Title: Wager sell back option

Description:
FIELD 
     This disclosure generally relates to wagering. 
     BACKGROUND 
     An organization, company, institution or other entity that accepts bets or places wagers for bettors on the general outcome of events (e.g., on scores or other attributes of sporting events) is referred to as a sports book. The role of the sports book is to act as a market maker for sports wagers. The sports book accepts wagers placed on either team or competitor, and maintains a point spread which aims to ensure a profit (i.e., the vigorish) for the sports book regardless of the outcome of the wager by attempting to attract an equal dollar amount of wagers for each team or competitor of a particular event. Sports books in general are continually striving to improve profits while maintaining current bettors&#39; interest and attracting new bettors. 
     SUMMARY 
     According to one example, a request to place a wager on an event may be received from a user. An option to cancel the wager in exchange for a refund amount may be presented for purchase to the user. Presenting the option may include presenting for selection by the user at least a first exercise time and a second exercise time, the first exercise time having a first fee associated therewith and the second exercise time having a second fee associated therewith. A price of the option may be based on the fee associated with the exercise time selected by the user. Selection of the first exercise time may allow the user to cancel the wager at least prior to the first exercise time in exchange for the refund amount, and selection of the second exercise time may allow the user to cancel the wager at least prior to the second exercise time in exchange for the refund amount. The refund amount associated with each of the first and second exercise times may be the same amount. An indication may be received that the user is purchasing the option. With the purchase, a selection by the user of either the first exercise time and/or the second exercise time may also be received. An indication may be recorded (such as in/on a memory device, paper, etc) that the user has paid for the option, the price of the option being based on, for example, the fee associated with the exercise time selected by the user. An indication may be received that the user is exercising the option. A determination may then be made as to when the indication is received as compared to the exercise time. If the indication is received at least prior to the selected exercise time, the wager may be canceled in exchange for the refund amount. In the alternative, if the indication is received after the selected exercise time, for example, the option may expire, the user&#39;s wager may remain in place/not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. As another alternative, the selected exercise time may pass without the user exercising the option/without receiving an indication that the user is exercising the option. Again, the option may expire, the user&#39;s wager may remain in place/may not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. 
     According to another and/or additional example, a request to place a wager on an event may be received from a user. A plurality of options to cancel the wager in exchange for a refund amount may be presented to the user, the plurality of options including at least a first option and a second option. The first option may have associated therewith a first exercise time and a first price, and the second option may have associated therewith a second exercise time and a second price. Selection of the first option may allow the user to cancel the wager at least prior to the first exercise time in exchange for the refund amount, and selection of the second option may allow the user to cancel the wager at least prior to the second exercise time in exchange for the refund amount. The refund amount associated with each of the first and second options may be the same amount. An indication may be received that the user is purchasing at least one of the first option and the second option. An indication may be received that the user is exercising the purchased option. A determination may then be made as to when the indication is received as compared to the exercise time associated with the purchased option. If the indication is received at least prior to the exercise time associated with the purchased option, the wager may be canceled in exchange for the refund amount. In the alternative, if the indication is received after the exercise time associated with the purchased option, for example, the option may expire, the user&#39;s wager may remain in place/not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. As another alternative, the exercise time associated with the purchased option may pass without the user exercising the purchased option/without receiving an indication that the user is exercising the purchased option. Again, at the option may expire, the user&#39;s wager may remain in place/may not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. 
     According to another and/or additional example, a request to place a wager on an event may be received from a user. An option to cancel the wager may be presented for purchase to the user for a price. The option may include a plurality of exercise times including at least a first exercise time and a second exercise time. The first exercise time may have a first refund amount associated therewith and the second exercise time may have a second refund amount associated therewith. The second exercise time may be subsequent to the first exercise time. The option may allow the user to cancel the wager prior to and/or at the first exercise time in exchange for the first refund amount, and/or to cancel the wager at and/or after the first exercise time and prior to and/or at the second exercise time in exchange for the second refund amount. An indication may be received that the user is purchasing the option. An indication may be received that the user is exercising the option. A determination may then be made as to when the indication is received as compared to the exercise times associated with the option. If the indication is received prior to and/or at the first exercise time associated with the option, the wager may be canceled in exchange for the first refund amount. If the indication is received at and/or after the first exercise time and prior to and/or at the second exercise time associated with the option, the wager may be canceled in exchange for the second refund amount. In the alternative, if the indication is received at and/or after the second exercise time associated with the option, the option may expire, the user&#39;s wager may remain in place/not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. As another alternative, all exercise times associated with the option may pass without the user exercising the option/without receiving an indication that the user is exercising the option. Again, the option may expire, the user&#39;s wager may remain in place/may not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. 
     According to another and/or additional example, a request to place a wager on an event may be received from a user. An option to cancel the wager may be presented for purchase to the user for a price. An indication may be received that the user is purchasing the option. An indication may be received that the user is exercising the option. Responsive to the user exercising the option, the wager may be canceled in exchange for a refund amount. The user may be required to use at least a portion of the refund amount to place another wager.

The system memory  269  includes read-only memory (“ROM”)  270  and random access memory (“RAM”)  272 . A basic input/output system (“BIOS”)  271 , which can form part of the ROM  270 , contains basic routines that help transfer information between elements within the peripheral computing system  114 , such as during start-up. 
     The payment disbursement computer system  262  may also include one or more media drives  273  (e.g., a hard disk drive, magnetic disk drive, and/or optical disk drive) for reading from and writing to computer-readable storage media  274  (e.g., hard disk, optical disks, and/or magnetic disks). The computer-readable storage media  274  may, for example, take the form of removable media. For example, hard disks may take the form of Winchester drives, optical disks can take the form of DVDs, while magnetic disks can take the form of magnetic floppy disks or diskettes. The media drive(s)  273  communicate with the processing unit  268  via one or more system buses. The media drives  273  may include interfaces or controllers (not shown) coupled between such drives and the system bus, as is known by those skilled in the relevant art. The media drives  273 , and their associated computer-readable storage media  274 , provide nonvolatile storage of computer-readable instructions, data structures, program engines and other data for the payment disbursement computer system  262 . Although described as employing computer-readable storage media  274  such as hard disks, optical disks and magnetic disks, those skilled in the relevant art will appreciate that payment disbursement computer system  262  may employ other types of computer-readable storage media that can store data accessible by a computer, such as magnetic cassettes, flash memory cards, compact discs (“CD”), Bernoulli cartridges, RAMs, ROMs, smart cards, solid state drives, etc. 
     Program engines, such as an operating system, one or more application programs, other programs or engines and program data, can be stored in the system memory  269 . Program engines may include instructions for handling security such as password or other access protection and communications encryption. The system memory  269  may also include communications and server programs, for example a Web server that permits the payment disbursement computer system  262  to disburse and/or initiate disbursement of payments to bettors for winning bets and/or for refunds resulting from the bettor exercising a sports book ticket sell back option (e.g., during a specified break in play during a an event or other indicated period). The other indicated period may be any period from the moment the wager is placed through completion of the entire sporting event or through completion of any portion of the sporting event. The payments may be disbursed directly via a cash dispenser or voucher printer (not shown) connected to or integrated with the payment disbursement computer system  262 , or electronically to an account associated with the bettor. The electronic disbursements may be sent over the Internet and/or via Web applications and/or other networks or electronic payment and deposit systems such as automated clearing house (ACH) systems, credit and debit systems, etc, via network  108 . 
     While described as being stored in the system memory  269 , the operating system, application programs, other programs/engines, program data and/or browser can be stored on the computer-readable storage media  274  of the media drive(s)  273 . An operator can enter commands and information into the payment disbursement computer system  262  via a user interface  275  through input devices such as a touch screen or keyboard  276  and/or a pointing device  277  such as a mouse. Other input devices can include a microphone, joystick, game pad, tablet, scanner (e.g., sports book ticket scanner), etc. These and other input devices are connected to the processing unit  269  through an interface such as a serial port interface that couples to the system bus, although other interfaces such as a parallel port, a game port or a wireless interface or a universal serial bus (“USB”) can be used. A display or monitor  278  may be coupled to the system bus via a video interface, such as a video adapter. The Payment disbursement computer system  262  can include other output devices, such as speakers, printers, etc. 
     The payment disbursement computer system  262  includes instructions stored in non-transitory computer-readable storage media that cause the processor(s) of the payment disbursement computer system  262  to pay bettors bets won that had been placed on sporting events through the sports book wagering computer system  202  from various bettor computer systems over the LAN  208  or WAN  210 , including, for example, those from Bettor A computer system  264  and Bettor B computer system  266 . For example, the sports book wagering computer system  202  may disburse or initiate disbursement of a ticket (paper or electronic) indicating a wager placed for a bet made on a sporting event by Better A. 
     The payment disbursement computer system  262  also includes instructions stored in non-transitory computer-readable storage media that cause the processor(s) of the payment disbursement computer system  262  to refund bettors amounts determined and communicated by the refund amount determination module  240  of the sports book wagering computer system  202  when the bettor exercises a previously purchased sports book ticket sell back option during a specified break in play or other indicated period of the sporting event on which the original bet was placed. The other indicated period may be any period from the moment the wager is placed through completion of the entire sporting event or through completion of any portion of the sporting event. 
     For example, Bettor A may have purchased on option to sell back the sports book ticket disbursed by the sports book wagering computer system  202  during half time of the sporting event on which the bet was made for a refund amount determined at the time the option is exercised. In some embodiments, this refund amount may not fall below a guaranteed pre-determined minimum amount. To exercise the purchased option, at some time (e.g., half time, between periods, between innings or quarters) during the sporting event, Bettor A sells back the sports book ticket issued by the sports book wagering computer system  202  by bringing, sending, initiating sending or otherwise communicating the ticket (if electronic) to the payment disbursement computer system  262  to have the ticket electronically scanned or read, have the refund amount determined (either by the sports book wagering computer system  202  or the payment distribution computer system) and receive the determined refund amount. In some embodiments, the payment distribution computer system may wirelessly authenticate the Bettor A computer system  264  (e.g., via a near field communications (NFC) or radio frequency identification (RFID) chip in the Bettor A computer system  264  and/or the payment distribution computer system  262 ) to enable payment disbursement to Bettor A. Note that although the refund amount determination module  240  and historical analytics module  244  are shown as being part of the sports book wagering computer system  202 , one or both of these modules may also or instead be part of the payment disbursement computer system  262 . 
     In instances where the refund amount determination module  240  is part of the payment disbursement computer system  262 , the payment disbursement computer system  262  includes instructions stored in non-transitory computer-readable storage media that cause the processor(s) of the payment disbursement computer system  262  to receive additional information and analyses from the sports book wagering computer system  202  regarding historical statistical data of outcomes of previous sporting events of the same type as the current sporting event on which the bet was made and corresponding to the same breaks in play or corresponding intervals in the previous sporting events and other corresponding factors at the same breaks in play or corresponding intervals in the previous sporting events to determine a refund amount. 
     The Bettor A computer system  264  may have one or more identical or similar components to the previously described computer systems, for example a processing subsystem  280  including one or more non-transitory processor and computer-readable memories, a media subsystem including one or more drives and computer-readable storage media, and one or more user interface subsystems  282  including one or more keyboards, keypads, displays, pointing devices, graphical interfaces, scanners and/or printers. 
     The Bettor A computer system  264  includes program instructions stored in non-transitory computer-readable storage media such as those program instructions of a Web browser  284  configured to access the services of the sports book wagering computer system  202  and the payment disbursement computer system (e.g. to remotely place wagers on sporting events, purchase sports book ticket sell back options, remotely exercise previously purchased sports book ticket sell back options, collect refunds and payments, etc.). The browser  284  in the depicted embodiment is markup language based, such as Hypertext Markup Language (HTML), Extensible Markup Language (XML) or Wireless Markup Language (WML), and operates with markup languages that use syntactically delimited characters added to the data of a document to represent the structure of the document. A number of Web clients or browsers are commercially available such as those from Mozilla, Google and Microsoft. 
     The Bettor B computer system  266  may have identical or similar components to the previously described computer systems, for example a processing subsystem  286  including one or more non-transitory processor and computer-readable memories, a media subsystem  288  including one or more drives and computer-readable storage media, and one or more user interface subsystems  290  including one or more keyboards, keypads, displays, pointing devices, graphical interfaces scanners and/or printers. 
     For example, the Bettor B computer system  266  may include program instructions stored in non-transitory computer-readable storage media such as those program instructions of a Web browser  290  configured to access the services of the sports book wagering computer system  202  similar to that of Web browser  284  of Bettor A computer system  264  described above. Although there are only two example bettor computer systems depicted in  FIG. 2 , there may be fewer or more such bettor computer systems operably connected to LAN  208  and/or WAN  210  in various other embodiments. 
       FIG. 3  is a diagram of an example user interface  300  for Bettor A to purchase a sports book wager ticket sell back option, one or more portions of which may be displayed on a display of the sports book wagering computer system  202  or the Bettor A computer system  264 , according to one illustrated embodiment. Bettor A may purchase a sports book ticket sell back option via the interface  300 , for example, during the process of placing a wager on the corresponding sporting event. Also, a bettor may purchase a sports book ticket sell back option via the interface  300  after placing a wager on the corresponding sporting event at some time before completion of the specified break in play or indicated period in which the option may be exercised and after having received the sports book ticket indicating the initial wager. There may be some instances after which the sports book ticket has been issued where the purchase of a sell back option is barred or suspended, including, but not limited to: changes in the point spread, key players becoming injured, key players being removed from the roster, catastrophic events for a particular team, etc. The purchased option may be an option to be exercised by the bettor during a specified break in play or indicated period of the corresponding sporting event (e.g., during half time) for the bettor to receive compensation (i.e., a determined refund amount) for canceling the wager. 
     However, in some embodiments, all or some of the user interface  300  features and components described herein may be configured for the sports book employee or agent to use instead of or in addition to Bettor A, such as to place wagers and make sell back option purchases on behalf of Bettor A. In other embodiments, neither the sports book nor Bettor A need use the Bettor A interface to place the wager and have the sell back option purchased by Bettor A. For example, Bettor A enters a sports book and walks up to the existing counter that is manned by an agent of the sports book. Bettor A then asks to make a wager on any of the types of bets for any of the events offered for wagering by the sports book (e.g., football, basketball, soccer, baseball, boxing, individual competitions, horse racing, political events, competitions, contests, activities of public figures, activities of celebrities, etc.). The types of bets or wagers may include, but are not limited to: straight, total score (i.e., over/under), money line, teasers, future bets, if-win only (single action), if-win-tie-cancel (double action), reverse wagers, buying points, proposition bets, etc. Bettor A then requests that the agent include the sell back option in his wager, or the agent makes a proffer to the bettor and the bettor accepts the proffer from the agent to participate in the sell back option. One or more of the above acts may be performed independently or in conjunction with the Bettor A interface. In one embodiment, where Bettor A declines purchase or selection of the sports book ticket sell back option (or had never been offered the sell back option) and after having been issued the sports book ticket indicating the initial wager, the sports book may make an unsolicited offer to Bettor A for Bettor A to have the opportunity to purchase a sports book ticket sell back option at some time before completion of the break in play or indicated period in which the option may be exercised. The offer to Bettor A may be displayed on a public display in the establishment of the sports book, shown on a display of the Bettor A computer system, printed out and provided to Bettor A, posted on a sports book web site, and/or electronically communicated via email, text message, fax, etc. 
     An added cost of participating in the sell back option, if any, is determined by the sports book and can range from 0% to any percentage of the ticket price or amount wagered and/or any fixed dollar amount chosen by the sports book. At the discretion of the sports book, an added cost of participating in the sell back option at the time the wager is placed may be higher or lower than an added cost of participating in the sell back option when purchased at a later time. 
     The refund amount (i.e., the value of the sports book ticket sell back option to Bettor A) may be determined at the time the sports book ticket sell back option is exercised based on a current probability or odds at the specified break in play of the event or indicated period of whether the bettor will win the bet for which the wager was made. The option may also include a minimum guaranteed amount (e.g., 20 percent of the wager amount, or other pre-determined minimum amount) to be refunded to the bettor should the bettor choose to exercise the option. However, in some embodiments, there may be no guaranteed percentage refund or other guaranteed refund amount. The current calculated refund amount (i.e., current value of the sports book ticket sell back option) may be shown to the bettor at the time of the purchase of the sports book ticket sell back option, or at any time from the moment the sporting event begins to (and including) the period when the bettor can exercise the option. For example, this value may be displayed on a public display in the establishment of the sports book, shown on the display  302  of Bettor A Interface, printed out and provided to the bettor, posted on a sports book web site, and/or electronically communicated via email, text message, fax, etc. 
     In one example embodiment, user interface item  308  of user interface  300  is configured to display an indication of the type of bet placed (e.g., ABC), display an indication of which sporting event on which the bet was placed (e.g., XYZ game) and the wager amount (e.g., $110). Before the ticket is issued, user interface item  302  is configured to display a prompt asking Bettor A whether the Bettor A would like to purchase the sports book ticket sell back option for a minimum guaranteed percent return of the wager amount should the option be exercised by the bettor during the specified break in play. In some embodiments, there may be no minimum guaranteed percentage refund or other guaranteed refund amount. The user interface item  302  also indicates the up-front and non-refundable cost or fee charged to the bettor for the purchase of the option. For example, this fee may be a percentage of the wager (e.g., 2.5 percent of the wager). However, other percentage amounts, flat fees or combinations thereof, may be selectively charged by the sports book wagering computer system and will be indicated to the bettor via the user interface item  302 . In some embodiments, the sports book may elect to charge no fee or a refundable fee for the purchase of a sports book ticket sell back option and this will be indicated to the bettor via the user interface item  302 . 
     The user interface item  302  also includes controls selectable by the bettor to indicate whether the bettor wants to purchase the sports book ticket sell back option. For example, the user selects icon or button  312  to indicate the bettor wants to purchase the option and selects icon or button  314  to indicate that the bettor does not want to purchase the option. In embodiments where user interface item  302  is displayed on the sports book wagering computer system  202 , the interface  300  may also include a ticket printing and retrieval component  316  configured to print a sports book ticket indicating the wager and whether the sports book ticket sell back option had been purchased. These indications may be printed or otherwise encoded (e.g., on a bar code) on the sports book ticket dispensed by the ticket printing and retrieval component  316 . 
     In other embodiments (e.g., those in which the user interface item  302  is displayed on a Bettor A computer system  264  remote from the sports book wagering computer system  202 ), the sports book ticket may be issued electronically as an electronic ticket stored on the sports book wagering computer system  202  and/or Bettor A computer system  264 . The electronic sports book ticket is associated with the bettor via a code communicated to the bettor via the sports book wagering computer system, an account of the bettor, or other bettor credentials which may be verified at a point when the sports book ticket is used to redeem a payment amount for winning the bet placed or for exercising the purchased sports book ticket sell back option. 
     In embodiments where Bettor A declines purchase of a sports book ticket sell back option via the interface  300  after placing a wager on the corresponding sporting event at some time before completion of the specified break in play or indicated period in which the option may be exercised and after having been issued the sports book ticket indicating the initial wager, Bettor A may scan the sports book ticket (e.g., via a machine-readable symbol such as barcode or 2-D code symbol, radio frequency identification or RFID transponder, near field communication (NFC) chip, or optical character recognition or OCR) at a scanner that is part of the ticket printing and retrieval component  316  or located elsewhere (such as on the Bettor A computer system  264 ) to have the sell back option associated with the wager associated with the sports book ticket. In embodiments involving an electronic ticket, Bettor A may input the code provided to Bettor A at the time the ticket was issued or other credentials associated with the electronic ticket or Bettor A in order to have the sell back option associated with the wager indicated by the previously issued sports book ticket. 
       FIG. 4  is a diagram of an example user interface  400  for facilitating Bettor A to exercise a sports book wager ticket sell back option, one or more portions of which may be displayed on a display of the sports book wagering computer system  202 , payment disbursement computer system  262  or the Bettor A computer system  264 , according to one illustrated embodiment. Bettor A may exercise a sports book ticket sell back option (such as the one purchased via interface  300  of  FIG. 3 ) via the interface  400  of  FIG. 4 , for example, during the specified break in play or indicated period during which the previously purchased option is valid. 
     However, in some embodiments, all or some of the user interface  400  features and components described herein may be configured for the sports book employee, cashier or agent to use instead of or in addition to Bettor A, such as to exercise sell back option purchases on behalf of Bettor A and provide refunds to Bettor A. In other embodiments, neither the sports book nor Bettor A need use the user interface  400  to exercise the sports book ticket sell back option. For example, Bettor A may approach a sports book cashier, ask to exercise the sports book sell back option, hand the cashier the sports book ticket, and the cashier will provide the refund amount in cash to Bettor A. If Bettor A chooses to exercise the sports book ticket sell back option, Bettor A can make it known to the sports book via any system that the sports book cares to use, whether it be electronic or open utterance. For example, Bettor A can scan or insert the sports book ticket, or input information related to the sports book ticket, into an electronic kiosk, approach a sports book agent at the counter of the sports book or enter a code or scan the sports book ticket using an electronic handheld device, etc. However, with respect to Bettor A, such a kiosk, sports book agent and/or handheld device may use any combination of features and components described herein of the user interfaces  300  and  400 , the sports book wagering system  202 , payment disbursement computer system  262  and/or the Bettor A computer system to perform the sports book ticket sell back option purchase, exercise the sports book ticket sell back option, determine the sports book ticket refund amount and/or to disburse the refund amount. 
     The period in which the sports book ticket sell back option may be exercised may be during all or a portion of any number of periods during the sporting event as determined by the sports book. For example, sports book ticket sell back options may be exercised during a single specific break in play, multiple specific breaks in play or any break in play. A break in play is defined as stoppage in play for any reason whatsoever and may include, but is not limited to the following breaks in play during various sporting events: half time period, quarter periods, between innings or half-innings in baseball games, time-outs, between regulation time and overtime periods, during caution laps of an auto race, the period intermission of a hockey game, between rounds of a boxing match, prior to specific types of plays (e.g., field goals, two-point conversions, penalty kicks or shots), a period prior to a specific event that might occur during the course of play including but not limited to: an injury to a player, removal of a pitcher, or changing of a goaltender. In some embodiments, the sports book may determine that sports book ticket sell back options may be exercised from the moment the wager is recorded through completion of one of: a portion of the sporting event or the entirety of the sporting event. This is defined as an indicated period and may be communicated to the bettor at the time of placement of the wager. In one embodiment, sports book ticket sell back options may be exercised during both ongoing play as well as all breaks in play during the indicated period. 
     For example, during half time of a sporting event for which Bettor A has placed a wager and purchased a half time sports book ticket sell back option, Bettor A may approach the sports book wagering computer system  202 , approach a cashier, employee or other agent using the sports book wagering computer system  202 , or utilize the Bettor A computer system  264  to exercise the option. The bettor may scan their sports book ticket at the component  324  on the sports book wagering computer system  202  that is configured to scan and read information encoded in machine-readable symbols on or RFID transponders on or in the sports book ticket. Component  324  may then print out a voucher or coupon that the bettor may redeem for cash, or in some alternative embodiments, dispense cash. In other embodiments, instead of receiving a voucher or cash, the bettor may receive instructions at or via component  324  on how to obtain a refund. For example, component  324  may print, display or otherwise communicate instructions for the bettor on how, when and where to proceed to a cashier, refund machine, etc. with the ticket to complete the refund process. Component  324  may also communicate a refund code or other item to use alone or in conjunction with the ticket to enable the bettor to receive the refund or initiate an electronic transaction to credit an account of the bettor to provide the refund. 
     In some embodiments, where the sports book ticket is an electronic ticket, Bettor A may provide a code associated with the electronic ticket given to the Bettor at the time the ticket was issued, or input credentials associated with Bettor A and/or the issued electronic ticket at the sports book wagering computer system  202  or the Bettor A computer system  264 . User Interface item  318  may then be displayed to Bettor A including a prompt asking Bettor A whether Bettor A would like to exercise the sports book ticket sell back option purchased for that sports book ticket. User Interface item  318  also displays the refund amount (i.e., the value of the sports book ticket sell back option to Bettor A). User interface item  308  of user interface  400  is also configured to display an indication of the type of bet placed (e.g., ABC), display an indication of which sporting event on which the bet was placed (e.g., XYZ game) and the wager amount (e.g., $110). 
     The user interface item  318  also includes controls (e.g., user selectable icons, dialog boxes, keys, switches, buttons) selectable by the bettor to indicate whether the bettor wants to exercise the sports book ticket sell back option. For example, the user selects icon or button  320  to indicate the bettor wants to exercise the option and selects icon or button  322  to indicate that the bettor does not want to exercise the option. If Bettor A selects icon or button  320  to indicate the Bettor A wants to exercise the option, then a refund amount will be dispensed, sent or otherwise issued to Bettor A. 
     As mentioned above, the refund amount (i.e., the value of the sports book ticket sell back option to Bettor A) may be determined at the time the sports book ticket sell back option is exercised based on a current probability or odds at the specified break in play or indicated period of the sporting event of whether the bettor will win the bet for which the wager was made. The option may also include a minimum guaranteed amount (e.g., 20 percent of the wager amount, or other pre-determined minimum amount) to be refunded to the bettor should the bettor choose to exercise the option. However, in some embodiments, there may be no guaranteed percentage refund or other guaranteed refund amount. The current calculated refund amount (i.e., current value of the sports book ticket sell back option) may be shown to the bettor at the time of the purchase of the sports book ticket sell back option, or at any time from the moment the wager is placed to (and including) the period when the bettor can exercise the option. For example, this value may be displayed on a public display in the establishment of the sports book, shown on the display  318  of Bettor A Interface, printed out and provided to the bettor, posted on a sports book web site, and/or electronically communicated via email, text message, fax, etc. In some embodiments, Bettor A may approach and/or activate user interface  400  and scan or otherwise input the bettor&#39;s ticket or ticket information for the user interface  400  to display the current refund amount (i.e., the value of the sports book ticket sell back option to Bettor A). 
     The current refund amount (i.e., the value of the sports book ticket sell back option to Bettor A) can be determined in any manner that the sports book chooses. The sports book may use a historical probability model, a coin toss or whatever system or method they choose. In some circumstances, the sports book may choose to outsource determination of the current refund amount to an individual or entity deemed to have special expertise in the regard. Even when outsourced, the sports book retains ultimate authority to determine the current refund amount. 
     The determined refund amount may be based on statistical analyses of previous sporting events with characteristics in common with the current sporting events on which wagers have been placed and for which sports book sell back options have been purchased and, in some embodiments, based on intrinsic game factors. These intrinsic game factors may include, but are not limited to, catastrophic player injury, illness or other disqualification occurring before the specified break in play or before completion of the indicated period during which the sports book ticket sell back option may be exercised. In some embodiments, these analyses may be based on historical data regarding outcomes of previous sporting events of the same type as the current sporting event at corresponding breaks in play or corresponding intervals in the previous sporting events and other corresponding factors at the corresponding breaks in play or corresponding intervals in the previous sporting events. 
     For example, if Bettor A placed a wager of $110 on the Bears playing the Packers (the home team) that the Packers would not win by more than 7 points, and at half time the score is Bears 10 and Packers 17, then the analysis would determine the percentage probability (based on historical NFL statistical data) that a home team winning by 7 points at half time gains at least one point in the second half. The sports book wagering computer system  202  or payment disbursement computer system  262  would then use this probability to determine the amount to refund Bettor A at half time for exercising the sports book ticket sell back option. The percentage amount refunded may also be reduced further (e.g., by one percentage point) as an additional charge to the bettor and would thus increase the amount earned by the sports book organization (i.e., the vigorish). Using the present example, if the probability that a home team winning by 7 points at half time gains at least one point in the second half is 75 percent and the sports book organization reduces the percentage or odds paid to the bettor, e.g., by one percentage point, then the amount refunded Bettor A should Bettor A exercise the sell back option would be (25%-1%)*$210=$50.40. However, in other examples using the same wager amount, based on the probability and the additional percentage charged by the sports book organization, if the determined amount to refund falls below the guaranteed refund amount (e.g., falls below 20 percent of the wager amount), the amount refunded would instead be the guaranteed refund amount of 20 percent of the wager amount ($22). 
     In some embodiments, the determined amount to refund the bettor when the bettor exercises the sports book ticket sell back option may also be based on or adjusted according to the current number of sports book ticket sell back options being exercised for a particular winning or losing team during previous breaks in play and/or the current specified break in play or indicted period to keep a more even amount of sports book ticket sell back options being exercised for each team of the sporting event. For example, if the current number or dollar value of sell back options being exercised for team A of the sporting event far outweighs that of team B of the sporting event, then the determined amount to be refunded for exercising sports book ticket sell back options for team A may be reduced and/or the determined amount to be refunded for exercising sports book ticket sell back option for team B may be increased. 
       FIG. 5  shows a method  500  for electronically processing a request to purchase a sports book wager ticket sell back option, according to one illustrated embodiment. In some embodiments, the bettor may communicate the request for a wager in any manner to a designated agent of the sports book. The agent may then enter the wager into the sports book wagering computer system  202 . 
     The method  500  starts at  502 , in which the sports book wagering computer system  202  shown in  FIG. 2  receives a request to place a wager of a bettor for a bet regarding an outcome of an event. 
     At  504 , the sports book wagering computer system  202 , receives an indication of whether the bettor has selected to purchase an option to be exercised at will by the bettor during a break in play or an indicated period for the bettor to receive compensation to cancel the wager. 
     At  506 , if the received indication indicates the bettor has selected to purchase the option, the sports book wagering computer system  202  determines an option fee to charge the bettor for the purchase of the option. 
     Also, in some embodiments, a sports ticket sell back option may automatically be sold or included as part of the bet placed by the bettor, and the bettor automatically charged without prompting the bettor to indicate whether the bettor desires to purchase the sports book ticket sell back option. 
       FIG. 6  shows a method  600  for electronically determining an amount to refund a bettor who is exercising a sports book wager ticket sell back option previously purchased by the bettor that is useful in the method of  FIG. 5 , according to one illustrated embodiment. For example, during the specified break in play during the sporting event, or in some embodiments, during any time from the point the wager is placed until the sporting event ends, the sports book wagering computer system  202  may receive an indication that the bettor is exercising the purchased option and in response to the received indication that the bettor is exercising the purchased option, the sports book wagering computer system  202  determines an amount to refund to the bettor according to the method  600 . Although the method  600  described below includes determining an amount to refund to the bettor based on a probability of whether the bettor will win the bet for which the wager was made, the amount to refund to the bettor may be based on anything. For example the amount to refund to the bettor may be based on, including but not limited to: a probabilistic method, a random method, recommendation from an individual or entity, voting, a static amount, etc. In various embodiments, the amount to refund to the bettor may be any percentage of the original bet made by the bettor, a flat amount, or any combination thereof. 
     The method  600  starts at  602 , in which the sports book wagering computer system  202  shown in  FIG. 2  determines a current probability (e.g., percentage probability) at the break in play or the indicated period of whether the bettor will win the bet for which the wager was made. 
     At  604 , the sports book wagering computer system  202  subtracts a determined amount (e.g., percentage, flat fee, or combination thereof) from a number reflecting the current probability (e.g., percentage probability) to obtain a multiplier. 
     At  606 , the sports book wagering computer system  202  multiplies the multiplier by an amount that would be paid to the bettor if the better were to win the bet to obtain a bettor refund amount factor. 
     At  608  the sports book wagering computer system  202  subtracts a determined amount (e.g., percentage, flat fee, or combination thereof) from the bettor refund amount factor to determine the amount to refund to the bettor. 
     The method may further include varying the determined amount to refund to the bettor during the sporting event before the specified break in play or the indicated period, or at any time before the event on which the wager was placed ends, the varying of the determined amount being indicated by the electronic sports book wagering system. 
     The method may further include communicating the varied determined amount to the bettor in response to the varying of the determined amount. 
     For example, the method may include communicating the determined amount to the bettor at any point from a time ranging from the moment the wager is recorded to a point during the break in play or the indicated period during the sporting event. The receiving an indication that a bettor intends to exercise the option may include receiving the indication that the bettor intends to exercise the purchased option during the break in play or the indicated period during the sporting event. 
     The method may further include communicating the determined amount to the bettor in response to the received indication that the bettor intends to exercise the purchased option. 
     The up-front and non-refundable cost or fees charged to the bettor for the purchase of the sell back option as well as the fees charged at  604  and  608  are determined by the sports book. Such fees may vary depending, for example, on the individual sporting event, type of wager, or even from time to time (e.g., the day of the week the wager is placed and/or the day of the week the sporting event occurs). At the discretion of the sports book, some or all of the fees may be waived as a means of increasing current bettor&#39;s interest and attracting new bettors. In addition to the waiving of fees, the sports book may incentivize the purchase and/or redemption of sports book ticket sell back options by offering casino compensation (“comps”) including but not limited to: free or discounted hotel room stays, show tickets, meals, drinks, gift certificates, etc. 
       FIG. 7  shows a method  700  for electronically issuing a ticket indicative of a wager associated with a sports book wager ticket sell back option, according to one illustrated embodiment. 
     The method  700  starts at  702 , in which the sports book wagering computer system  202  shown in  FIG. 2  receives an indication that a bettor has placed a wager for a bet regarding an outcome of an event. 
     At  704 , the sports book wagering computer system  202  receives an indication that the bettor has paid an option fee to purchase an option to be exercised at will by the bettor during a break in play or an indicated period, for the bettor to receive compensation to cancel the wager. 
     At  706 , the sports book wagering computer system  202  issues a ticket to the bettor indicative of the wager associated with the purchased option. As mentioned above the sports book ticket may be an electronic ticket that is issued electronically such as by providing a code to the bettor associated with the electronic ticket or associating the issued electronic ticket with a bettor account or other bettor credentials. 
       FIG. 8  shows a method  800  for electronically initiating payment to a bettor who is exercising a sports book wager ticket sell back option previously purchased by the bettor, according to one illustrated embodiment. 
     The method  800  starts at  802 , in which the sports book wagering computer system  202  or the payment disbursement computer system  262  shown in  FIG. 2  receives, during a break in play or an indicated period, an indication that a bettor is exercising an option for the bettor to receive compensation to cancel a wager previously placed by the bettor on an outcome of an event. 
     At  804 , the sports book wagering computer system  202  or the payment disbursement computer system  262 , in response to the received indication that the bettor is exercising the option, determines an amount to refund to the bettor. 
     At  806 , the sports book wagering computer system  202  or the payment disbursement computer system  262  initiates a disbursement of the amount to refund to the bettor. The refund to the bettor may be paid in currency or in the form of a credit or any item that has a value to the bettor, including casino compensation (“comps”), including, but not limited to: free or discounted hotel room stays, show tickets, meals, drinks, gift certificates, etc. 
     At  806 , the sports book wagering computer system  202  or the payment disbursement computer system  262  then cancels the wager. For example, the wager may be removed from the sports book wagering computer system  202  or otherwise indicated by the sports book wagering computer system  202  as being canceled, invalid or no longer in effect. 
     Sell Back Option with Multiple Exercise Choices 
     According to another example of a sell back option, in connection with a bettor/patron/user placing/making a wager on an event for a wager amount W and/or subsequently thereto, a bettor may be presented with an opportunity to purchase an option to cancel/purge/sell back the wager in return/exchange for a refund/refund amount/refund payment/cancelation amount/cancelation payment of R. In connection with presenting the opportunity to purchase the option, the bettor also may be provided/presented with a plurality (e.g., two or more) of choices as to when the option may be exercised, or in other words, with a plurality of choices as to when the option may expire. For example, there may be four choices, although fewer or more choices may be presented. Hence, the bettor may have the choice to purchase the option with a first exercise time of X1, a second exercise time of X2, a third exercise time of X3, and/or a fourth exercise time of X4, or in other words, an option with an expiry of X1, X2, X3, and/or X4. According to this example, expiry/exercise time X4 may be subsequent to/after expiry/exercise time X3, expiry/exercise time X3 may be subsequent to/after expiry/exercise time X2, and expiry/exercise time X2 may be subsequent to/after expiry/exercise time X1. According to a further aspect of this example, regardless of which selection(s) of exercise/expiry time(s) the bettor may choose, the refund amount R may be the same. In addition, according to this example, each exercise time may have an associated price/cost/fee, such as exercise time X1 having a price P1, exercise time X2 having a price P2, exercise time X3 having a price P3, and exercise time X4 having a price P4. According to this example, one or more of prices P1, P2, P3, and P4 may be different and in particular, each of prices P1, P2, P3, and P4 may be different. According to one example, P1 may be less than P2, P2 may be less than P3, and P3 may be less than P4. In other words, a longer expiry time may have a larger price. 
     Hence, according to this example sell back option a bettor, in connection with placing/making a wager and/or subsequently thereto, may purchase an option to cancel/purge the wager in return for a refund amount R. In addition, the bettor may make a selection as to how much time the bettor would like to make the decision as to whether to cancel/purge the wager through the exercise of the option including, for example, up to and/or including an exercise time X1, up to and/or including a later exercise time X2, up to and/or including a still later exercise time X3, or up to and/or including a still later exercise time X4. According to this example, the more time the bettor would like, the higher the price the bettor may pay for the option. Again, each exercise time may have the same refund amount of R with the difference being that the bettor may pay more for additional time to make a decision. 
     As an example, a bettor may place a $100 wager on a football game, such as the Packers vs. the Bears. In connection with making/placing this wager and or subsequently thereto, the bettor may be presented the possibility of purchasing an option to purge/cancel the wager for a refund amount of 25% of the wager amount, or $25. In addition, the user may be presented with four expiry times, each with a different price:
         Cost $2.50: The bettor may exercise the option at any time up to, and possibly including, the end of the first quarter (e.g., before the start of the second quarter) for a refund of $25.   Cost $5.50: The bettor may exercise the option at any time up to, and possibly including, the end of the second quarter (e.g., before the start of the third quarter) for a refund of $25.   Cost $9.00: The bettor may exercise the option at any time up to, and possibly including, the end of the third quarter (e.g., before the start of the fourth quarter) for a refund of $25.   Cost $12.50: The bettor may exercise the option at any time up to, and possibly including, the 2 minute warning in the fourth quarter (e.g., before the start of play after the 2 minute warning) for a refund of $25.       

     Hence, the bettor, if deciding to purchase the option, may select a desired expiry/exercise time for the option. The price of the option may be the price associated with the selected expiry/exercise time. Thereafter, the bettor may choose to exercise the option at any time up to and/or including, for example, the selected expiry/exercise time and receive in return the refund amount R, thereby canceling/purging the original wager. If the expiry time passes without the bettor exercising the option, the option expires, the bettor&#39;s wager remains in place/is not canceled, and the bettor either wins or loses the wager based on the outcome of the event wagered on. 
     One skilled in the art will recognize that rather than a bettor being presented with the possibility of purchasing an option and that option having a plurality of exercise times the bettor may select from, in connection with a bettor making/placing a wager and or subsequently thereto, the bettor may be presented the possibility of purchasing any one or more of a plurality of options to purge/cancel a wager. Here, each option may have the same refund amount R, but with each option having a progressively longer exercise time, and each option having a progressively larger price. Using the above example again where a bettor may place a $100 wager on a football game, such as the Packers vs. the Bears, the bettor may be presented the possibility of purchasing any one or more of four options to purge/cancel the wager for a refund amount of 25% of the wager amount, or $25:
         Option 1: Cost $2.50—The bettor may exercise the option at any time up to, and possibly including, the end of the first quarter (e.g., before the start of the second quarter) for a refund of $25.   Option 2: Cost $5.50—The bettor may exercise the option at any time up to, and possibly including, the end of the second quarter (e.g., before the start of the third quarter) for a refund of $25.   Option 3: Cost $9.00—The bettor may exercise the option at any time up to, and possibly including, the end of the third quarter (e.g., before the start of the fourth quarter) for a refund of $25.   Option 4: Cost $12.50—The bettor may exercise the option at any time up to, and possibly including, the 2 minute warning in the fourth quarter (e.g., before the start of play after the 2 minute warning) for a refund of $25.       

     One skilled in the art will recognize that the above described characteristics of this example option are merely examples and that other variations are possible, including the application of the option to sports other than football and to events other than sports. 
     Turning to further example aspects of this example sell back option, the refund/cancelation amount R that a bettor may be offered in connection with each exercise/expiry time choice of a given option (and may subsequently receive upon exercising the option) may be a predetermined amount. In other words, at the time the offer to purchase the option is made to the bettor/at the time the bettor is contemplating the purchase of the option, the refund amount associated with each of the exercise/expiry times choices may be determined and may be conveyed to the bettor such that if the bettor were to purchase the option with a selected exercise time and later decide to exercise the option, the bettor may know the refund amount he/she will receive. The refund amount may be a guaranteed amount. In other words, the refund amount may be such that the bettor knows that if the bettor purchases the option and later decides to exercise the option, the bettor is guaranteed to receive the refund amount (e.g., exactly the determined refund amount or at least at a minimum, the determined refund amount). 
     The refund/cancelation amount R offered in connection with each exercise/expiry time choice of a given option may be determined in various fashions. For example, the refund amount R may be a set/constant amount, regardless of the wager made (e.g., regardless of the amount wagered, regardless of the amount/potential amount the bettor stands to win (i.e., the payout) on the wager associated with the option, etc.). For example, the refund amount associated with each of the exercise times associated with an offered option may be the same amount, and this amount may be the same for all bettors. A sports book, for example, may set the refund amount. As a further and/or additional example, the refund amount may vary depending on when the option is purchased by a bettor. For example, assuming the option may be purchased up to some set time (which may be some time before and/or including the start of an event, some set time into the event, etc.), the refund amount may vary depending on when the option is purchased relative to that set time. For example, assuming the option may be purchased up to one minute before the start of an event wagered on (set time), the refund amount may be a first amount if the option is purchased any time up to one day prior to that set time, and may be a second amount if purchased any time thereafter up to the set time. The refund amount may decrease the closer to the set time the option is purchased. Alternatively, the refund amount may increase the closer to the set time the option is purchased. The refund amount may change at preset times (which may or may not be made known to the bettor) as the set time approaches, e.g.: one week before, one day before, twelve hours before, one hour before, etc. As another and/or additional example, for a given sporting event for example, say football, the refund amount(s) may be the same amount for every game on a given day, or may be different across one or more of the games played on that day (e.g., every bettor that wagers on game A and exercises an associated option may receive refund amount R1 and every bettor that wagers on game B and exercises an associated option may receive a different refund amount R2). As another and/or additional example, the refund amount(s) may be the same across different sporting events for example, say football and baseball, and/or may be different across one or more different sporting events. Other variations are possible. 
     According to another and/or additional example, the refund amount R may be determined as a function of the wager amount W of the wager associated with the option. For example, the refund amount may be a predetermined percentage of the wager amount W. A sports book, for example, may set the percentage. For example, if a bettor wagers $100 on an event and the predetermined percentage is 25%, upon exercising the option the bettor may receive $25 ($100×25%) regardless of the exercise time the bettor selects (i.e., the refund amount associated with each exercise time of the option offered to the bettor may be $25). The predetermined percentage may vary depending on when the option is purchased. For example, assuming the option may be purchased up to some set time, the percentage may vary depending on when the option is purchased relative to that set time. For example, assuming the option may be purchased up to one minute before the start of an event wagered on, the percentage may be a first amount if the option is purchased any time up to one day prior to that set time, and may be a second amount if purchased any time thereafter up to the set time. The percentage may decrease the closer to the set time the option is purchased. Alternatively, the percentage may increase the closer to the set time the option is purchased. The percentage may change at preset times (which may or may not be made known to the bettor) as the set time approaches, e.g. one week before, one day before, twelve hours before, one hour before, etc. As another and/or additional example, the percentage may vary depending on the size of the wager amount W. For example, the percentage may decrease the larger the wager amount. Alternatively, the percentage may increase the larger the wager amount. As an example, wager amounts may be classified into ranges with a percentage associated with each range. As another and/or additional example, the percentage may vary according to the payout/potential-estimated payout a bettor stands to win on the wager associated with the option. For example, the percentage may decrease the larger the payout. Alternatively, the percentage may increase the larger the payout. As an example, payouts may be classified into ranges, with a percentage associated with each range. As another and/or additional example, for a given sporting event for example, say football, the percentage(s) may be the same for every game on a given day, or may be different across one or more of the games played on that day. As another and/or additional example, the percentage(s) may be the same across different sporting events, for example say football and baseball, and/or may be different across one or more different sporting events. Other variations are possible. 
     As another and/or additional example of the refund amount R being determined as a function of the wager amount W, wager amounts may be broken into ranges with each range having an associated refund amount. For example, the refund amount may generally decrease the larger the wager amount. Alternatively, the refund amount may generally increase the larger the wager amount. As another and/or additional example, the refund amount for one or more of the ranges may vary depending on when the option is purchased. For example, assuming the option may be purchased up to some set time, the refund amount for one or more of the ranges may vary depending on when the option is purchased relative to that set time. In general, the refund amounts across the ranges may decrease the closer to the set time the option is purchased. Alternatively, the refund amounts across the ranges may increase the closer to the set time the option is purchased. The refund amounts across the ranges may change at preset times (which may or may not be made known to the bettor) as the set time approaches, e.g. one week before, one day before, twelve hours before, one hour before, etc. As another and/or additional example, for a given sporting event for example, say football, the ranges and/or refund amount(s) across the ranges may be the same amount for every game on a given day, or may be different across one or more of the games played that day. As another and/or additional example, the ranges and/or refund amounts across the ranges may be the same across different sporting events, for example say football and baseball, and/or may be different across one or more different sporting events. Other variations are possible. 
     Refund amounts may be determined as a function of wager amounts in other fashions than those discussed herein. As a further and/or additional example, for wager amounts of a specified size/amount or larger, the sell back option may not be made available to a bettor. As another example, the sell back option may not be made available to a bettor unless the wager amount is of a minimum size/amount. A sports book for example, my specify the wager amount to which the option is available/not available. As a still further and/or addition example, the wager amount used to determine the refund amount may have a ceiling. In other words, when a bettor wagers an amount greater than a specified ceiling amount, the wager amount used to determine the refund amount may be set at the ceiling amount. For example, assuming the refund amount may be a predetermined percentage of the wager amount W, say 25%, and that the ceiling amount is $100, if a bettor wagers $110, the refund amount may be set at 25% of the ceiling amount of $100 (i.e., $25) rather than 25% of $110. A sports book for example, my specify the ceiling amount. Other variations are possible. 
     According to another and/or additional example, the refund amount may be determined as a function of the payout/potential-estimated payout a bettor stands to win on the wager associated with the option. For example, the refund amount may be a predetermined percentage of the payout/potential payout. A sports book, for example, may set the percentage. For example, if a bettor stands to win $100 on a bet and the predetermined percentage is 25%, upon exercising the option the bettor may receive $25 ($100×25%) regardless of the exercise time the bettor selects (i.e., the refund amount associated with each exercise time of the option offered to the bettor may be $25). As similarly discussed above, the predetermined percentage may vary depending on when the option is purchased. For example, the percentage may decrease the closer to the set time the option is purchased. Alternatively, the percentage may increase the closer to the set time the option is purchased. The percentage may change at preset times (which may or may not be made known to the bettor) as the set time approaches, e.g. one week before, one day before, twelve hours before, one hour before, etc. As another and/or additional example, the percentage may vary depending on the size of the payout/potential payout. For example, the percentage may decrease the larger the payout/potential payout. Alternatively, the percentage may increase the larger the payout/potential payout. As an example, payout/potential payouts may be classified into ranges with a percentage associated with each range. As another and/or additional example, the percentage may vary according to the wager amount. For example, the percentage may decrease the larger the wager amount. Alternatively, the percentage may increase the larger the wager amount. As an example, wager amounts may be classified into ranges, with a percentage associated with each range. As another and/or additional example, for a given sporting event for example, say football, the percentage(s) may be the same for every game on a given day, or may be different across one or more of the games played on that day. As another and/or additional example, the percentage(s) may be the same across different sporting events, for example say football and baseball, and/or may be different across one or more different sporting events. Other variations are possible. 
     As another and/or additional example of the refund amount R being determined as a function of the of the payout/potential payout, payouts/potential payouts may be broken into ranges with each range having an associated refund amount. For example, the refund amount may generally decrease the larger the payout/potential payout. Alternatively, the refund amount may generally increase the larger the payout/potential payout. As another and/or additional example, the refund amount for one or more of the ranges may vary depending on when the option is purchased. For example, the refund amounts across the ranges may decrease the closer to the set time the option is purchased. Alternatively, the refund amounts across the ranges may increase the closer to the set time the option is purchased. The refund amounts across the ranges may change at preset times (which may or may not be made known to the bettor) as the set time approaches, e.g. one week before, one day before, twelve hours before, one hour before, etc. As another and/or additional example, for a given sporting event for example, say football, the ranges and/or refund amounts across the ranges may be the same amount for every game on a given day, or may be different across one or more of the games played on that day. As another and/or additional example, the ranges and/or refund amounts across the ranges may be the same across different sporting events, for example say football and baseball, and/or may be different across one or more different sporting events. Other variations are possible. 
     Refund amounts may be determined as a function of payouts/potential payouts in other fashions than those discussed herein. As a further and/or addition example, for payouts/potential payouts of a specified size or larger, the sell back option may not be made available to a bettor. A sports book for example, my specify the payouts/potential payouts to which the option is available/not available. As a still further and/or addition example, the payouts/potential payouts used to determine the refund amount may have a ceiling. In other words, when a payout/potential payout is greater than a specified ceiling amount, the payout/potential payout used to determine the refund amount may be set at the ceiling amount. A sports book for example, my specify the ceiling amount. Other variations are possible. 
     Turning to further example aspects of this example sell back option, the price associated with each exercise time may be a set/constant amount, regardless of the wager made/amount wagered and/or regardless of a payout/potential-estimated payout a bettor may stand to win. Hence, each bettor may be presented with the same price(s). A sports book, for example, may set the price(s). According to another and/or additional example, one or more of the prices may be determined as a function of the wager amount W of the wager associated with the option. As a still further and/or addition example, the wager amount used to determine the price(s) may have a ceiling. In other words, when a bettor wagers an amount greater than a specified ceiling amount, the wager amount used to determine the price(s) may be set at the ceiling amount. According to another and/or additional example, one or more of the prices may be determined as a function of the payout/potential-estimated payout a bettor stands to win on the wager associated with the option. As a still further and/or addition example, the payouts/potential payouts used to determine the price(s) may have a ceiling. In other words, when a payout/potential payout is greater than a specified ceiling amount, the payout/potential payout used to determine the price(s) may be set at the ceiling amount. As a further and/or additional example, one or more of the prices may vary depending on when the option is purchased by a bettor. For example, one or more of the prices may decrease the closer to a set time the option is purchased. Alternatively, one or more of the prices may increase the closer to the set time the option is purchased. As another and/or additional example, for a given sporting event for example, say football, one or more of the prices may be the same amount for every game on a given day, or may be different across one or more of the games played on that day). As another and/or additional example, one or more of the prices may be the same across different sporting events for example, say football and baseball, and/or may be different across one or more different sporting events. Other variations are possible. 
     Turning to further example aspects of this example sell back option, the choices of exercise/expiry times that a bettor may be offered in connection with a given option may be defined in various fashions. For example, one or more of the exercise times associated with a given option may be:
         one or more specific times of day, such a 12 noon, 1 PM, etc;   one or more specified amounts of time into a sporting event, such as 15 minutes into an event, 30 minutes into the event, etc;   one or more specified times during an event such as end of one or more quarters in football, end of one or more innings or half innings in baseball, one or more times in a hockey event including intermission, end of one or more rounds in boxing, one or more furlongs in a horse race, completion of one or more laps by a lead car, e.g., in auto racing, etc.; and/or   one or more occurrences of a specific event within a sporting event such as, the occurrence of the first field goal, the occurrence of the nth field goal, the occurrence of a team scoring, the occurrence of the first team to score z points, etc.       

     One skilled in the art will recognize that other variations of exercise/expiry times are possible including any variations of the above. For example, one or more of the exercise/expiry times offered in connection with an option may be a specific time of day and another may be a specified time during an event such as end of a quarter in football. As another example, one or more of the exercise/expiry times offered in connection with an option may be before the start of an event and/or during the event. 
     According to further example aspects of this example sell back option, the option may be offered to a bettor in connection with the bettor placing/making a wager on an event and/or subsequently thereto. In either instance, the bettor may be required to purchase the option when offered, or may be given the opportunity to purchase the option at a later time. According to one example, there may be a set time when the option is no longer available for purchase. As discussed herein, for example, the option may be available for purchase up to some set time before and/or including the start of an event, some set time into the event, etc. The option may be available for purchase up to some set time before the first exercise/expiry time offered in connection with option. For example, referring to the example option discussed herein offered in connection with the Packers vs. the Bears, the option may be available for purchase up to some set time before the end of the first quarter or in other words, some set time before the exercise/expiry time that costs $2.50. 
     According to another and/or additional example, the number of choices of exercise/expiry times offered to a bettor may change depending on when the offer to purchase the option is made to a bettor and/or when a bettor decides to purchase the option. For example, referring again to the example option discussed herein offered in connection with the Packers vs. the Bears, when a bettor places a wager on the game, the bettor may be offered the possibility to purchase the option along with selecting any one of the four exercise/expiry times. Assuming the bettor declines to purchase the option at that time, but then later decides he/she would like to purchase the option, one, two, or three of the choices of exercise/expiry times may no longer be available. For example, the bettor may no longer have the choice of selecting the exercise/expiry time that costs $2.50. This may occur for example, if the end of the first quarter is too close to and/or has already occurred at the time the bettor decides to purchase the option. As another example, assuming a first bettor places a wager on the game at one time and a second bettor places a wager on the game at later second time, the second bettor may be offered a fewer selection of exercise/expiry times than the first bettor. For example, the first bettor may be offered all four choices, while the second bettor may be offered three, two, or just one of the choices. This may occur for example, if the first bettor places a wager well before the start of the game and the second bettor places a wager after the start of the game, such as to close to and/or after the first quarter. Other variations are possible. 
     According to further example aspects of this example sell back option, once a bettor has selected an exercise/expiry time and purchased the option, there may be designated points (e.g., discrete points) during the period of time leading up to the selected exercise time at which the bettor may exercise the option. For example, the bettor may be allowed to exercise an option only between plays, i.e., at a stoppage of action in a game. Alternatively, the bettor may be allowed to exercise the option at any time during the period of time leading up to the selected exercise time. Other variations are possible. As another example, of the offered choices of exercise/expiry times offered to a bettor for a given option, one or more of the exercise/expiry times may have different criteria as to how and/or when the bettor may exercise the option. 
     According to further example aspects of this example sell back option, a bettor may place a bet and pay the wager amount W with cash, using an established account, points, such as comp points, credits, etc. Similarly, the bettor may purchase the option with cash, using an established account, points, such as comp points, credits, etc. Similarly, the refund amount R may be paid to the bettor in cash, crediting of an account, in points, such as comp points, credits, etc. According to one example, the user may place the wager, purchase the option, and receive the refund in different forms: place the wager in cash, purchase the option with credits, receive the refund in comp points. According to another example, if the wager and/or option is placed in one form, the refund amount R may be required to be paid in the same form. Other variations are possible. 
     According to another example of this sell back option as applied to football for example (although other sports and/or events may apply), in connection with making/placing a wager with wager amount W and/or subsequently thereto, a bettor may be presented the possibility of purchasing an option to purge/cancel the wager for a refund amount R which may be a defined percentage of the wager amount W. The defined percentage may be a value between 20-30%, such as 25%. In addition, the bettor may be presented with up to four and/or possibly more (or less) exercise/expiry times, each with a different price:
         Cost $A: The bettor may exercise the option at any time up to, and possibly including, the end of the first quarter (e.g., before the start of the second quarter) for a refund of $25.   Cost $B: The bettor may exercise the option at any time up to, and possibly including, the end of the second quarter (e.g., before the start of the third quarter) for a refund of $25.   Cost $C: The bettor may exercise the option at any time up to, and possibly including, the end of the third quarter (e.g., before the start of the fourth quarter) for a refund of $25.   Cost $D: The bettor may exercise the option at any time up to, and possibly including, the 2 minute warning in the fourth quarter (e.g., before the start of play after the 2 minute warning) for a refund of $25.       

     Cost A may be a cost between $2.40 and $2.60, such as $2.50, cost B may be a cost between $5.40 and $5.60, such as $5.50, cost C may be a cost between $8.90 and $9.10, such as $9.00, and cost D may be a cost between $12.40 and $12.60, such as $12.50. Other variations are possible. Other costs and percentages may be used. 
     Each of a wager and/or an associated sell back option according to the present example may be presented to, purchased by, and/or exercised by a bettor through the use of one or more computing systems, through the use of one or more employees/agents (of a sports book for example) or any combination thereof as similarly discussed herein for other example sell back options. For example, each of a wager and/or an associated sell back option may be presented to, purchased by, and/or exercised by a bettor through the use of system  100  and/or  200  and/or one or more employees/agents (of a sports book for example). For example, each of a wager and/or an associated sell back option according to the present example may be presented to, purchased by, and/or exercised by a bettor entirely electronically, entirely though the use of one or more employees/agents (of a sports book for example) (such as over the counter), or some combination thereof. Similarly, each of a wager and/or an associated sell back option according to the present example may be managed electronically, such as through the use of system  100  and/or  200 , by one or more employees/agents (of a sports book for example), or any combination thereof. 
     One skilled in the art will recognize that the above described characteristics of this example option are merely examples and that other variations are possible, including the application to sports and to events other than sports. 
     Referring now to  FIG. 9 , there is shown an example method  900  for offering, purchasing, and exercising an option. At step  902 , a request to place a wager on an event may be received from a user. At step  904 , an option to cancel the wager in exchange for a refund amount may be presented for purchase to the user. Presenting the option may include presenting for selection by the user at least a first exercise time and a second exercise time, the first exercise time having a first fee associated therewith and the second exercise time having a second fee associated therewith. A price of the option may be based on the fee associated with the exercise time selected by the user. Selection of the first exercise time may allow the user to cancel the wager at least prior to the first exercise time in exchange for the refund amount, and selection of the second exercise time may allow the user to cancel the wager at least prior to the second exercise time in exchange for the refund amount. The refund amount associated with each of the first and second exercise times may be the same amount. At step  906 , an indication may be received that the user is purchasing the option. With the purchase, a selection by the user of either the first exercise time and/or the second exercise time may also be received. At step  908 , an indication may be recorded (such as in/on a memory device, paper, etc) that the user has paid for the option, the price of the option being based on, for example, the fee associated with the exercise time selected by the user. At step  910 , an indication may be received that the user is exercising the option. A determination may then be made as to when the indication is received as compared to the exercise time (step  912 ). If the indication is received at least prior to the selected exercise time, at step  914  the wager may be canceled in exchange for the refund amount. In the alternative, if the indication is received after the selected exercise time, for example, at step  916  the option may expire, the user&#39;s wager may remain in place/not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. As another alternative, the selected exercise time may pass without the user exercising the option/without receiving an indication that the user is exercising the option. Again, at step  916  the option may expire, the user&#39;s wager may remain in place/may not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. 
     Referring now to  FIG. 10 , there is shown another example method  1000  for offering, purchasing, and exercising an option. At step  1002 , a request to place a wager on an event may be received from a user. At step  1004 , a plurality of options to cancel the wager in exchange for a refund amount may be presented to the user, the plurality of options including at least a first option and a second option. The first option may have associated therewith a first exercise time and a first price, and the second option may have associated therewith a second exercise time and a second price. Selection of the first option may allow the user to cancel the wager at least prior to the first exercise time in exchange for the refund amount, and selection of the second option may allow the user to cancel the wager at least prior to the second exercise time in exchange for the refund amount. The refund amount associated with each of the first and second options may be the same amount. At step  1006 , an indication may be received that the user is purchasing at least one of the first option and the second option. At step  1008 , an indication may be received that the user is exercising the purchased option. A determination may then be made as to when the indication is received as compared to the exercise time associated with the purchased option (step  1010 ). If the indication is received at least prior to the exercise time associated with the purchased option, at step  1012  the wager may be canceled in exchange for the refund amount. In the alternative, if the indication is received after the exercise time associated with the purchased option, for example, at step  1014  the option may expire, the user&#39;s wager may remain in place/not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. As another alternative, the exercise time associated with the purchased option may pass without the user exercising the purchased option/without receiving an indication that the user is exercising the purchased option. Again, at step  1014  the option may expire, the user&#39;s wager may remain in place/may not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. 
     Sell Back Option with Multiple Exercise Times 
     According to another example of a sell back option, in connection with a bettor/patron/user placing/making a wager on an event for a wager amount W and/or subsequently thereto, a bettor may be presented with an opportunity to purchase an option for a price P to cancel/purge/sell back the wager in return for a refund amount/refund payment/cancelation amount/cancelation payment of R. The option, according to this example, may have a plurality (e.g., two or more) of exercise/expiry times associated with it. For example, there may be four exercise/expiry times (although fewer or more exercise times may be used) such as: a first exercise time of X1, a second exercise time of X2, a third exercise time of X3, and a fourth exercise time of X4, or in other words, an option with four exercise times of X1, X2, X3, and X4. According to this example, exercise/expiry time X4 may be subsequent to/after exercise/expiry time X3, exercise/expiry time X3 may be subsequent to/after exercise/expiry time X2, and exercise/expiry time X2 may be subsequent to/after exercise/expiry time X1, although other variations are possible. Accordingly, if a bettor purchases the option, the bettor may exercise the option/cancel the wager according to any one of the exercise times X1, X2, X3, and/or X4. According to an aspect of this example, regardless of which exercise/expiry time the bettor may eventually choose to exercise the option against, the price P of the option may be the same. According to a further aspect of this example option, each exercise time may have a refund amount associated with it, such as exercise time X1 having a refund amount R1, exercise time X2 having a refund amount R2, exercise time X3 having refund amount R3, and exercise time X4 having a refund amount R4. According to this example, one or more of refund amounts R1, R2, R3, and R4 may be different and in particular, each of refund amounts R1, R2, R3, and R4 may be different. According to one example, R1 may be more than R2, R2 may be more than R3, and R3 may be more than R4. In other words, a longer expiry time may have a smaller refund amount. Nonetheless, other variations are possible including R1 being less than R2, R2 being less than R3, and R3 being less than R4. Hence, according to this example option, given an event wagered on of a certain duration, for example, the refund amount a bettor receives for exercising the option is based on, for example, when into the event the option is exercised or in other words, how much time is remaining in the event when the option is exercised. 
     Hence, according to this example sell back option a bettor, in connection with placing/making a wager and/or subsequently thereto, may purchase an option for a price P to cancel/purge the wager. At the time the option is presented, an associated table for example, of exercise/expiry times, such as exercise/expiry times X1, X2, X3, and X4 (where, e.g., X1&lt;X2&lt;X3&lt;X4), associated with the option may also be presented to the bettor. For each exercise/expiry time, the bettor may also be presented with an associated refund amount, such as R1, R2, R3, and R4. Hence, assuming the bettor purchases the option for a price P, the bettor may subsequently choose to do any one (or more) of:
         Exercise the option (thereby canceling/purging/selling back the wager) at some time up to and/or including exercise time X1 and receive in return refund amount R1;   Exercise the option (thereby canceling/purging/selling back the wager) at some time at and/or after X1 and up to and/or including exercise time X2 and receive in return refund amount R2;   Exercise the option (thereby canceling/purging/selling back the wager) at some time at and/or after X2 and up to and/or including exercise time X3 and receive in return refund amount R3;   Exercise the option (thereby canceling/purging/selling back the wager) at some time at and/or after X3 and up to and/or including exercise time X4 and receive in return refund amount R4; or   Not exercise the option, leaving the wager in place, and either winning or losing the wager based on the outcome of the event wagered on.       

     One skilled in the art will recognize that the above described characteristics of this example option are merely examples and that other variations are possible, including the application to sports and to events other than sports. 
     As an example, a bettor may place a $100 wager on a football game, such as the Packers vs. the Bears. In connection with making/placing this wager and or subsequently thereto, the bettor may be presented the possibility of purchasing an option to purge/cancel the wager for a price, such as $10. The option may also include four exercise/expiry times, each with a different refund amount:
         Exercise Time 1: The bettor may exercise the option at any time up to, and possibly including, the end of the first quarter (e.g., before the start of the second quarter) for a refund of $25.   Exercise time 2: The bettor may exercise the option at any time at and/or after the end of the first quarter and up to, and possibly including, the end of the second quarter (e.g., before the start of the third quarter) for a refund of $20.   Exercise time 3: The bettor can exercise the option at any time at and/or after the end of the second quarter and up to, and possibly including, the end of the third quarter (e.g., before the start of the fourth quarter) for a refund of $15.   Exercise time 4: The bettor can exercise the option at any time at and/or after the end of the third quarter and up to, and possibly including, the 2 minute warning in the fourth quarter (e.g., before the start of play after the 2 minute warning) for a refund of $10.       

     Turning to further example aspects of this example sell back option, the refund/cancelation amounts R that a bettor may be offered for each exercise/expiry time of a given option and may subsequently receive upon exercising the option may be predetermined amounts. In other words, at the time the offer to purchase the option is made to the bettor/at the time the bettor is contemplating the purchase of the option, the refund amounts may be determined and may be conveyed to the bettor such that if the bettor were to purchase the option and later decide to exercise the option, the bettor may know the refund amount he/she will receive based on when the option is exercised. The refund amounts may be guaranteed amounts. 
     As similarly discussed herein, one or more of the refund amounts for each of the associated exercise times of a given option may be a set/constant amount, may be a function of the amount wagered W (e.g., each refund amount may be a set percentage of the wager amount R), may be a function of the payout/potential payout on the wager, may vary depending on when the option is purchased, may or may not vary across games/events of the same and/or different types, etc., or any combination thereof. Again, if the refund amounts are a function of the wager amount and/or payout, a ceiling amount may be used as similarly discussed herein. As also discussed herein, a sell back option according to this example may not be made available to a bettor if the wager amount and/or payout is too large and/or unless the wager amount and/or payout is of a minimum size. Other variations are possible. 
     As similarly discussed herein, the price associated with this example sell back option may be a set/constant amount, regardless of the wager made/amount wagered and/or regardless of a payout/potential-estimated payout a bettor may stand to win. Hence, each bettor may be presented with the same price. A sports book, for example, may set the price. According to another and/or additional example, the price may be determined as a function of the wager amount W of the wager associated with the option and/or as a function of the payout/potential-estimated payout a bettor may stand to win on the wager associated with the option. Again, if the price is a function of the wager amount and/or payout, a ceiling amount may be used as similarly discussed herein. As a further and/or additional example, the price may vary depending on when the option is purchased by a bettor, may or may not vary across games/events of the same and/or different types, etc., or any combination thereof. Other variations are possible. 
     As similarly discussed herein, the exercise/expiry times for a given option according to this example may be defined in various fashions, including one or more exercise times being defined in different fashions. For example, one or more of the exercise/expiry times associated with the option may be a specific time of day and another may be a specified time during an event such as end of a quarter in football. As another example, one or more of the exercise/expiry times may be before the start of an event and/or during the event the option is associated with. Other variations are possible. 
     According to further example aspects of this example sell back option, the option may be offered to a bettor in connection with the bettor placing/making a wager on an event and/or subsequently thereto. In either instance, the bettor may be required to purchase the option when offered, or may be given the opportunity to purchase the option at a later time. According to one example, there may be a set time when the option is no longer available for purchase. As discussed herein, for example, the option may be available for purchase up to some time before and/or including the start of an event, some set time into the event, etc. The option may be available for purchase up to some time before the first exercise/expiry time offered in connection with the option. Other variations are possible. 
     According to another and/or additional example, the number of exercise/expiry times associated with an option may change/vary depending on when the offer to purchase the option is made to a bettor and/or when a bettor decides to purchase the option. For example, referring again to the example option discussed herein offered in connection with the Packers vs. the Bears, when a bettor places a wager on the game, the bettor may be offered the possibility to purchase the option along with the four exercise/expiry times. Assuming the bettor declines to purchase the option at that time, but then later decides he/she would like to purchase the option, one, two, or three of the exercise/expiry times may no longer be associated with the option. For example, the option may no longer include “Exercise time 1”. This may occur for example, if the end of the first quarter is too close to and/or has already occurred at the time the bettor decides to purchase the option. As another example, assuming a first bettor places a wager on the game at one time and a second bettor places a wager on the game at later second time, the second bettor may be offered an option with fewer exercise/expiry times than the first bettor. For example, the first bettor may be offered an option with all four exercise/expiry times, while the second bettor may be offered an option with three, two, or just one of the exercise/expiry times. This may occur for example, if the first bettor places a wager well before the start of the game and the second bettor places a wager after the start of the game, such as to close to and/or after the first quarter. Other variations are possible. 
     According to further example aspects of this example sell back option, once a bettor has purchased the option, there may be designated points (e.g., discrete points) during the period of time leading up to each exercise time at which the bettor may exercise the option. For example, the bettor may be allowed to exercise an option only between plays, i.e., at a stoppage of action in a game. Alternatively, the bettor may be allowed to exercise the option at any time during the period of time leading up to an exercise time. Other variations are possible. As another example, one or more of the exercise/expiry times associated with an option may have different criteria as to how and/or when the bettor may exercise the option. 
     Each of a wager and/or an associated sell back option according to the present example may be presented to, purchased, and/or exercised by a bettor through the use of one or more computing systems, through the use of one or more employees/agents (of a sports book for example) or any combination thereof as similarly discussed herein for other example sell back options. For example, each of a wager and/or an associated sell back option may be presented to, purchased, and/or exercised by a bettor through the use of system  100  and/or  200  and/or one or more employees/agents (of a sports book for example). For example, each of a wager and/or an associated sell back option according to the present example may be presented to, purchased, and/or exercised by a bettor entirely electronically, entirely though the use of one or more employees/agents (of a sports book for example) (such as over the counter), or some combination thereof. Similarly, each of a wager and/or an associated sell back option according to the present example may be managed electronically, such as through the use of system  100  and/or  200 , by one or more employees/agents (of a sports book for example), or any combination thereof. 
     Referring now to  FIG. 11 , there is shown an example method  1100  for offering, purchasing, and exercising an option. At step  1102 , a request to place a wager on an event may be received from a user. At step  1104 , an option to cancel the wager may be presented for purchase to the user for a price. The option may include a plurality of exercise times including at least a first exercise time and a second exercise time. The first exercise time may have a first refund amount associated therewith and the second exercise time may have a second refund amount associated therewith. The second exercise time may be subsequent to the first exercise time. The option may allow the user to cancel the wager prior to and/or at the first exercise time in exchange for the first refund amount, and/or to cancel the wager at and/or after the first exercise time and prior to and/or at the second exercise time in exchange for the second refund amount. At step  1106 , an indication may be received that the user is purchasing the option. At step  1108 , an indication may be received that the user is exercising the option. A determination may then be made as to when the indication is received as compared to the exercise times associated with the option (step  1110 ). If the indication is received prior to and/or at the first exercise time associated with the option, at step  1112  the wager may be canceled in exchange for the first refund amount. If the indication is received at and/or after the first exercise time and prior to and/or at the second exercise time associated with the option, at step  1114  the wager may be canceled in exchange for the second refund amount. In the alternative, if the indication is received at and/or after the second exercise time associated with the option, at step  1116  the option may expire, the user&#39;s wager may remain in place/not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. As another alternative, all exercise times associated with the option may pass without the user exercising the option/without receiving an indication that the user is exercising the option. Again, at step  1116  the option may expire, the user&#39;s wager may remain in place/may not be canceled, and the user may either win or lose the wager based on the outcome of the event wagered on. 
     Option Restrictions 
     According to another example aspect of any of the sell back options discussed herein, for example, if a bettor purchases an option and later decides to exercise the option, the bettor may be required to use all or at least a defined portion (which portion may be set by a sports book for example) of the refund amount to place another wager or wagers. According to one example, the bettor may not be allowed to combine the refund amount with additional funds (e.g., cash, point credits, etc) of the bettor when placing the new wager. According to another and/or additional example, the bettor may be allowed to combine the refund amount with additional funds (e.g., cash, point credits, etc) of the bettor when placing the new wager. The bettor may be notified of the restriction at the time the bettor is presented with an opportunity to purchase an option and/or when the bettor is purchasing the option. 
     According to one example, at the time the bettor exercises the option, the bettor may be required to immediately use the refund amount (or a defined portion thereof) to place one or more new wagers. For example, if exercising the option electronically as discussed herein, the bettor may be presented with an interface to place a new wager(s). If exercising the option through an employee/agent (of a sports book for example), the employee/agent may require the bettor to place another wager(s). 
     According to another and/or additional example, at the time the bettor exercises the option, the bettor may not be required to immediately use the refund amount (or a defined portion thereof) to place one or more new wagers. On the contrary, the bettor may be given an indefinite amount of time to use the refund amount (or a defined portion thereof) to place a new wager(s). As another and/or additional example, the bettor may be given a certain time limit to use the refund amount (or a defined portion thereof) to place a new wager(s). If the bettor does not place a new wager by that time, the bettor may forfeit/lose the refund. As another example, the bettor may be given until a certain event to use the refund amount (or a defined portion thereof) to place a new wager(s). If the bettor does not place a new wager by that event, the bettor may forfeit/lose the refund. For example, if the bettor exercises an option at halftime of a football game, the bettor may have until the end of the game to place a new wager. Other events are possible. 
     As a further example, the bettor may be given a graduated time/event schedule to use the refund amount. For example, assuming a bettor may be required to use the entire refund amount to place new wager(s), the bettor may have the entire refund amount available for new wagers up to a time T1. After T1, the bettor may lose a defined percentage/portion of the refund amount and have until a later time T2 to use the remaining refund amount. After T2, the bettor may lose another defined percentage/portion of the refund amount and have until a later time T3 to use the remaining refund amount, etc. As one example, the bettor may only lose a portion of the refund amount at each time/event transition if the bettor has not wagered a defined portion prior to that trigger. According to another example, the bettor may lose a portion of the refund amount at each trigger regardless of what the bettor has wagered thus far. Other variations are possible. As one example, assuming the bettor has a refund amount of $10 and loses 25% of the refund amount at each of T1, T2, etc., the bettor may have $10 for new wagers up to time T1. If the bettor has failed to place a new wager by T1, from T1 to T2 the bettor may now have $7.50 to place a new wager(s), etc. 
     As a further and/or additional example, once a bettor decides to place a new wager(s) using the refund amount, the bettor may be required to wager/use all of the refund amount at that time on one or more wagers. As another and/or additional example, assuming the bettor may be given a set amount of time and/or until the occurrence of a defined event to use the refund amount, once the bettor decides to place a new wager(s) using the refund amount, the bettor may be required to wager/use all of the refund amount at that time on one or more wagers. As another and/or additional example, the bettor may be allowed to place wagers using the refund amount at any time prior to the set time/defined event. 
     According to another example aspect of any of the sell back options discussed herein, a bettor may only be able to exercise a purchased option if the bettor is winning the wager associated with the option. Alternatively, a bettor may only be able to exercise a purchased option if the bettor is losing the wager associated with the option. 
     Referring now to  FIG. 12 , there is shown an example method  1200  for offering, purchasing, and exercising an option. At step  1202 , a request to place a wager on an event may be received from a user. At step  1204 , an option to cancel the wager may be presented for purchase to the user for a price. At step  1206 , an indication may be received that the user is purchasing the option. At step  1208 , an indication may be received that the user is exercising the option. At step  1210 , responsive to the user exercising the option, the wager may be canceled in exchange for a refund amount. The user may be required to use at least a portion of the refund amount to place another wager.
