   DESCRIPTION 
   The present invention relates in general to a gaming device, and more particularly to a gaming device having an element and element group selection and elimination bonus scheme. 
   BACKGROUND OF THE INVENTION 
   Many existing gaming machines, such as, traditional slot machines, include bonus schemes. Typically, a bonus round of the bonus scheme begins when the player reaches a bonus triggering event in the primary game of the gaming device. In slot machines that employ reels, the triggering event generally occurs when the player reaches a predetermined combination of symbols on the reels. In general, the bonus round provides the player with an opportunity to gain and accumulate a bonus value or award before the bonus round ends or terminates. 
   For example, a player may receive a relatively high bonus value for selecting a certain symbol and a relatively low bonus value for selecting another symbol. The bonus value awarded for the same symbol can also vary. For instance, if a player chooses a symbol on one occasion, the game may award a certain bonus value, and if the player chooses the same symbol on another occasion, the game may award a different bonus value. The bonus values which are awarded to a player are predetermined by a computer using known data or by randomly generating data based upon one or more mathematical formulas. For any single symbol or combination of symbols, these techniques often derive bonus values from a single set of possible bonus values. For example, existing gaming devices utilize pay tables which include various sets of values with each set corresponding to a predetermined combination of symbols. European Patent Application No. EP 0 945 837 A2 filed on Mar. 18, 1999 and assigned on its face to WMS Gaming, Inc. discloses a bonus scheme generally of this type. 
   To increase player enjoyment and excitement, it is desirable to provide players with gaming devices having new bonus schemes. 
   SUMMARY OF THE INVENTION 
   The present invention overcomes the above shortcomings by providing a gaming device and preferably a gaming device having an element and element group selection and elimination bonus scheme which provides an apparatus and method for randomly determining a plurality of awards for the player. The gaming device, and particularly the bonus scheme, performs a number of sequencing events to randomly select and eliminate elements and element groups or groups of elements. The game preferably awards a player bonus values until the game ends upon the selection of an eliminated element. 
   The gaming device provides at least one selection, elimination and preferably award sequence of events. Each of the successive selection sequences involve the selection of an element or elements from a group not previously eliminated and at least containing the previously selected element. If the successively or next selected element is not an eliminated element, then the game preferably awards another bonus value. The gaming device repeats the selection, elimination and preferably award sequencing until a previously eliminated element is selected. 
   The gaming device, and particularly the bonus scheme of the gaming device, can include a variety of different configurations to the enhance the player&#39;s entertainment and enjoyment during the selection, elimination and award sequencing of the bonus scheme. 
   In one embodiment, the present invention preferably provides a grid which includes a plurality of rows and columns. Each row and column is a group of elements. Each of the squares, rectangles or other like shapes of the grid hereafter referred to as positions. Each position is an element and created by the rows and columns are associated with an award. 
   When the player selects a game initiator, the present invention begins by randomly picking a position and its associated award from one row of the grid, preferably the top row. The present invention can alternatively start with any row or column of the grid. The game preferably provides a sequence that randomly picks a position for creating player excitement and enjoyment. In a preferred embodiment the game scrolls back and forth across the top row before selecting any of the positions and its associated award. Thereafter, the game prohibits the player from obtaining an award from the top row of positions (i.e., the group of elements in the top row). The game ends if in a subsequent position selection the game randomly stops on or selects a top row position or element. The game therefore suitably marks each of the positions of the top row as spent or exhausted. In one embodiment, the game distinguishes between marked and unmarked positions by lighting each unmarked position with a different color than the marked positions, i.e., spent or exhausted positions. 
   The game then randomly selects a position and a corresponding award from the column that contains the position or element which was selected from the top row. In selecting a position from the column, the game preferably employs the same display or sequence used in the top row in conjunction with selecting the top row position. After randomly selecting a position from the column, the game preferably suitably marks the entire column as spent or exhausted. It should be appreciated that if the game randomly selects the position of the top row of the column, the game ends because that position is spent or exhausted. If the game selects any other position, the player wins its associated award and the game preferably accumulates the award with any previous awards. 
   Assuming the game does not select the position of the spent top row, each of the positions of the previously selected and marked row and column are marked or spent and the game proceeds to randomly select a position and corresponding award from a new or next selected row which contains the position that was selected from the previously selected column. The game preferably employs the same display or sequence as described above. 
   If the game selects the position from the spent or marked column, the game ends. If not, the games awards the value associated with the next selected position and preferably accumulates the award with any previous awards. The present invention proceeds in this manner by alternating between unmarked rows and columns to randomly select a position from its respective row or column until the game selects a position belonging to a spent, exhausted, eliminated or marked row or column. The player wins the accumulation of awards from each of the selected positions, preferably, but not limited to, including the selected position from a marked row or column. It should be appreciated that successive random selections of the present invention have a decreasing chance of generating an award for the player. 
   While the present invention preferably employs a square or rectangle grid, the present invention can employ any shaped grid that enables the selection sequence as detailed above or like selection sequence to randomly select an award. The present invention can employ any type of display including, but not limited to, a plate of glass covering an array of lights or any known video monitor. The present invention preferably displays all available awards to the player at all times during the game. The game can alternatively employ one of a plurality of reveal sequences, wherein the game does not display all values at all times. The present invention also contemplates varying amounts of player interaction including, but not limited to: no player interaction (game automatically begins and ends); the player selecting a start button once, wherein the game automatically runs its course; the player initiating each random generation of a selected position; and the player initiating each selection or generation sequence and also separately initiating a sequence which randomly selects a position, wherein it appears that the player has control over the position selected. 
   The present invention is not limited to the rows and columns of the grid configuration as discussed above. In another embodiment, the groups are defined by a circular boundary or border that each contain a number of elements. 
   It is therefore, an object of the present invention to provide a gaming device having an element and element group selection and elimination bonus scheme. 
   It is a further object of the present invention to provide a gaming device having a position, row and column selection and elimination bonus scheme. 
   Other objects, features and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanying sheets of drawings, wherein like numerals refer to like parts, elements, components, steps and processes.

   As shown in  FIGS. 1A and 1B , gaming device  10  also includes a bet display  22  and a bet one button  24 . The player places a bet by pushing the bet one button  24 . The player can increase the bet by one credit each time the player pushes the bet one button  24 . When the player pushes the bet one button  24 , the number of credits shown in the credit display  16  decreases by one, and the number of credits shown in the bet display  22  increases by one. 
   At any time during the game, a player may “cash out” and thereby receive a number of coins corresponding to the number of remaining credits by pushing a cash out button  26 . When the player “cashes out,” the player receives the coins in a coin payout tray  28 . The gaming device  10  may employ other payout mechanisms such as credit slips redeemable by a cashier or electronically recordable cards which keep track of the player&#39;s credits. 
   Gaming device  10  also includes one or more display devices. The embodiment shown in  FIG. 1A  includes a central display device  30 , and the alternative embodiment shown in  FIG. 1B  includes a central display device  30  as well as an upper display device  32 . Gaming device  10  preferably displays a plurality of reels  34 , preferably three to five reels  34  in mechanical or video form at one or more of the display devices. However, it should be appreciated that the display devices can display any visual representation or exhibition, including but not limited to movement of physical objects such as mechanical reels and wheels, dynamic lighting and video images. A display device can be any viewing surface such as glass, a video monitor or screen, a liquid crystal display or any other display mechanism. If the reels  34  are in video form, the display device for the video reels  34  is preferably a video monitor. 
   Each reel  34  displays a plurality of indicia such as bells, hearts, fruits, numbers, letters, bars or other images which preferably correspond to a theme associated with the gaming device  10 . Furthermore, gaming device  10  preferably includes speakers  36  for making sounds or playing music. 
   As illustrated in  FIG. 2 , the general electronic configuration of gaming device  10  preferably includes: a processor  38 ; a memory device  40  for storing program code or other data; a central display device  30 ; an upper display device  32 ; a sound card  42 ; a plurality of speakers  36 ; and one or more input devices  44 . The processor  38  is preferably a microprocessor or microcontroller-based platform which is capable of displaying images, symbols and other indicia such as images of people, characters, places, things and faces of cards. The memory device  40  can include random access memory (RAM)  46  for storing event data or other data generated or used during a particular game. The memory device  40  can also include read only memory (ROM)  48  for storing program code which controls the gaming device  10  so that it plays a particular game in accordance with applicable game rules and pay tables. 
   As illustrated in  FIG. 2 , the player preferably uses the input devices  44 , such as pull arm  18 , play button  20 , the bet one button  24  and the cash out button  26  to input signals into gaming device  10 . In certain instances it is preferable to use a touch screen  50  and an associated touch screen controller  52  instead of a conventional video monitor display device. Touch screen  50  and touch screen controller  52  are connected to a video controller  54  and processor  38 . A player can make decisions and input signals into the gaming device  10  by touching touch screen  50  at the appropriate places. As further illustrated in  FIG. 2 , the processor  38  can be connected to coin slot  12  or bill acceptor  14 . The processor  38  can be programmed to require a player to deposit a certain amount of money in order to start the game. 
   It should be appreciated that although a processor  38  and memory device  40  are preferable implementations of the present invention, the present invention can also be implemented using one or more application-specific integrated circuits (ASIC&#39;s) or other hard-wired devices, or using mechanical devices (collectively referred to herein as a “processor”). Furthermore, although the processor  38  and memory device  40  preferably reside on each gaming device  10  unit, it is possible to provide some or all of their functions at a central location such as a network server for communication to a playing station such as over a local area network (LAN), wide area network (WAN), Internet connection, microwave link, and the like. The processor  38  and memory device  40  is generally referred to herein as the “computer.” 
   With reference to  FIGS. 1A ,  1 B and  2 , to operate the gaming device  10  in one embodiment the player must insert the appropriate amount of money or tokens at coin slot  12  or bill acceptor  14  and then pull the arm  18  or push the play button  20 . The reels  34  will then begin to spin. Eventually, the reels  34  will come to a stop. As long as the player has credits remaining, the player can spin the reels  34  again. Depending upon where the reels  34  stop, the player may or may not win additional credits. 
   In addition to winning credits in this manner, preferably gaming device  10  also gives players the opportunity to win credits in a bonus round. This type of gaming device  10  will include a program which will automatically begin a bonus round when the player has achieved a qualifying condition in the game. This qualifying condition can be a particular arrangement of indicia on a display device. The gaming device  10  preferably uses a video-based central display device  30  to enable the player to play the bonus round. Preferably, the qualifying condition is a predetermined combination of indicia appearing on a plurality of reels  34 . As illustrated in the five reel slot game shown in  FIGS. 1A and 1B , the qualifying condition could be the number seven appearing on three adjacent reels  34  along a payline  56 . It should be appreciated that the present invention can include one or more paylines displayed in a horizontal and/or diagonal fashion. 
   Bonus Scheme 
   If a player achieves a bonus triggering or qualifying condition while playing the game, the gaming device  10  automatically begins the bonus round of the present invention. At the beginning of the bonus round, the game exhibits or displays one or more symbols, sounds, indicators, selections, visual or audio representations or other graphical representations. The bonus scheme may involve a variety of game scenarios which involve awarding bonus values to a player upon the occurrence of certain events. The computer of the gaming device determines what a game exhibits or displays, game scenarios, the object of the game, how the game is played and the various events which occur in the game. The gaming device utilizes a monitor to display or exhibit the game scenarios, including the bonus round. The monitor includes a video monitor for displaying a video display of the game scenarios. However, the present invention is not limited to the use of a video monitor and can include any suitable display for exhibiting the game scenarios. 
   The present invention provides a bonus scheme that includes at least one selection, elimination and preferably award sequence of events. Each of the successive selection sequences involve the selection of an element or elements from a group not previously eliminated and at least containing the previously selected element. If the successively selected element is not an eliminated element, then the game preferably awards another bonus value. The gaming device repeats the selection, elimination, and preferably award sequencing until a previously eliminated element is selected. The present invention provides a plurality of groups that each contain at least one element and can include a variety of different configurations to enhance the player&#39;s entertainment and enjoyment during play. 
   As shown in  FIGS. 3  to  6 , one embodiment of the bonus scheme of the present invention is displayed as a grid  100  that has a plurality of rows  102  and columns  104  wherein each row  102  and column  104  has a plurality of positions  106 . Generally, each row and each column is a group of elements and each position is an element. 
   As illustrated in  FIG. 3 , the bonus round begins preferably when the player  108  depresses a start button  110  or other like triggering event. The game randomly selects a first position  112  from a first row  114  of the grid  100 . However, the game is not limited to selecting the first position  112  from the first row  114 . The game may select a first position  112  from any of the columns  104  and rows  102  that makeup the grid  100 . 
   The game makes a series of passes along the first row  114  prior to selecting the first position  112 . For example, the game can make a series of four passes and selects the first position  112  on the next or select pass. The game is not limited to the number or series of passes that it makes prior to selecting a position  106 , such as, the first position  112 . In order to facilitate excitement, the positions are randomly highlighted or highlighted in a predetermined order as displayed on the monitor (not shown) when the game makes a series of passes prior to selecting a position. The game utilizes a light box associated with the positions in order to highlight the positions. However, the game is not limited to the use of a light box and can include a variety of different and suitable highlighting mechanisms. 
   When the selected position is chosen, the selected position, such as the selected position  112 , remains highlighted to designate its selection as further illustrated in FIG.  3 . The highlighted and selected first position  112  corresponds to or is associated with an award or bonus value of 20. The bonus value of 20 is identified on an award display  116  or other like member for the player to monitor during the bonus round as illustrated in FIG.  3 . 
   Once the first position  112  is selected, the entire first row  114  is spent, exhausted or eliminated and marked as illustrated in FIG.  4 . By marking, the gaming device highlights the entire row or column (i.e., the group) containing the selected position (i.e. the selected element), such as the first row  114  as further illustrated in FIG.  4 . However, the present invention is not limited to marking by highlighting and can utilize a variety of different and suitable marking techniques. 
   The game next makes a series of passes along a first column  118  to randomly select a second position  120 . The first column  118  includes the first or previously selected position  112 . As further illustrated in  FIG. 4 , the position that corresponds to a bonus award of 50 was selected and highlighted. The bonus value of 50 was added to the previously selected bonus value and a cumulative bonus value of 70 is displayed in the award display  116  as illustrated in FIG.  4 . 
   When the position  120  of the first column  118  is selected, the entire first column is spent or exhausted and marked as further illustrated in FIG.  5 . The game continues and makes a series of passes to randomly select a next position along a second row  122  that includes the previously selected position  120  from the first column  118 . The selected position  124  of the second row  122  is highlighted and corresponds to a bonus value of 5 as illustrated in FIG.  5 . The newly awarded bonus value of 5 is added to the bonus value cumulative total for a new cumulative total of 75 as displayed in the award display  116  as illustrated in FIG.  5 . 
   The second row  122  is spent and marked as illustrated in FIG.  6 . The game continues by making a series of passes along a second column  126  to randomly select a position of the second column  126 . The second column  126  includes the previously selected position  124  of the second row  122 . As further illustrated in  FIG. 6 , the game ends because the selected and highlighted position  128  was a marked or spent position, i.e., the selected position  128  is from a marked row  122 . The selected bonus value is not added to the cumulative bonus value total. Therefore, the bonus round ends with a cumulative bonus value or award of 75 as further illustrated in FIG.  6 . 
   In another embodiment of the present invention as shown in  FIGS. 7  to  10 , the bonus round randomly selects a bonus award by performing the same sequencing as detailed above for the previously described bonus round. At game initiation, the bonus award or value that corresponds to each position  106  of the grid  100  are masked or not displayed as further illustrated in FIG.  7 . The game performs a series of passes along a column  130  to randomly select a position  132  and award the bonus value which corresponds or is associated with the selected position  132 . When the position  132  is selected, all of the bonus values of the column that contains the selected position  132  are displayed or unmasked and the entire column is visually marked as further illustrated in FIG.  8 . 
   The bonus round continues and makes a series of passes along the row  134  which includes the previously selected position  132  as illustrated in  FIG. 8. A  position  136  along this row  134  is randomly selected and its corresponding bonus value of 50 is added to the previously awarded bonus value of 5 for a cumulative total of 55 and displayed in the award display  116  as illustrated in  FIGS. 8 and 9 . All of the bonus values of this row  134  are displayed and the entire row  134  is visually marked as further illustrated in FIG.  9 . 
   The bonus round continues to the next selection sequence by making a series of passes along the column  138  that contains the previously selected position  136 . The next position  140  is randomly selected and its corresponding bonus value of 10 is added to the previous cumulative bonus value total of 55 for a new cumulative total of 65 as displayed in the award display  116  as illustrated in  FIGS. 9 and 10 . This column  138  is marked and all of its bonus values are revealed or unmasked as illustrated in FIG.  10 . 
   The bonus round continues to the next selection sequence by making a series of passes along the row  142 . As further illustrated in  FIG. 10 , the game ends because a position  144  of the marked column  138  was selected. The bonus award or value of this selected position  144  is not added to the cumulative bonus value total, and therefore, the cumulative bonus value total for this bonus round is 65 as displayed in the award display  116 . 
   The present invention is not limited to a square or rectangular-shaped grid as detailed above. A variety of different grid shapes may be utilized to facilitate and enhance the enjoyment and entertainment objectives of the present invention. For example, a cross-shaped grid  146  may be employed as illustrated in FIG.  11 . In  FIG. 12 , a square-shaped grid  148  that is missing an L-shaped section is another example of a grid shape that may be utilized. In  FIG. 13 , a polygonal-shaped grid  150  is further illustrated. 
   As illustrated in  FIGS. 14  to  20 , a variety of different sequences may be utilized to randomly select a bonus award or value from a grid configuration. As indicated in circle  152 , a bonus triggering event is the first step of each bonus round. As discussed above, the bonus triggering event occurred when the player depressed the start button. However, the bonus triggering event is not limited to this event and can include a variety of different events. For example, the game can initiate or activate the bonus round without any interaction from the player and can continue to play the bonus round until the game ends without further player interaction as illustrated in  FIG. 14  as indicated in box  153 . 
   In  FIG. 15 , the bonus awards are not displayed after the bonus triggering event as indicated in box  154 . A position is randomly selected as indicated in box  156 . If the selected position is a spent, exhausted or eliminated position as indicated in diamond  158 , then the bonus values for each of the corresponding selected positions are displayed as further indicated in box  160 , and the bonus round ends as shown in circle  162 . If the selected position is not spent as indicated in diamond  158 , then the bonus value that corresponds to or is associated with the selected position is displayed and another position is selected as further indicated in boxes  164  and  156 . These steps are repeated until a selected position is a terminating position, i.e., spent or exhausted. Thereafter, the game ends. 
   As illustrated in  FIG. 16 , the sequence of events are identical to those of  FIG. 15  except that the bonus value or award is displayed for each of the positions of the row or column from which a position is selected as indicated in box  168 . 
   In  FIG. 17 , the game automatically begins the sequence and proceeds to select positions and provide awards until the game randomly selects a position from a spent row or column as indicated in box  170 . Thereafter, the game ends as further indicated in circle  162 . 
   In  FIG. 18 , the game enables the player to selectively initiate the game, as indicated by box  172 . Once initiated, the sequence begins and randomly picks or selects a position from a row or column and provides an award until randomly selecting a position from a spent row or column, i.e., selecting a terminating position as indicated in box  174 . Thereafter, the game ends as further indicated in circle  162 . In  FIG. 19 , the game enables the player to initiate a sequence as indicated in box  172 . Once initiated, the sequence begins and randomly picks a position from a row or column as indicated in box  176 . If the position is not spent, then an award is provided and the selection sequence is repeated as indicated in diamond  178  and box  179 . If the position is spent, then the game ends as further indicated in diamond  178  and circle  162 . 
   In  FIG. 20 , the game enables the player to selectively initiate a sequence, as indicated in box  172 . Once initiated, the game begins the sequence and enables the player to selectively initiate a stop sequence as indicated in boxes  180  and  181 . The game randomly selects a position in response to the stop sequence as indicated in box  182 . If the position is not spent, then an award is provided and the selection sequence is repeated as indicated in diamond  184  and box  186 . If the position is spent, then the bonus round ends as further indicated in diamond  184  and circle  162 . 
   As previously discussed, the present invention is not limited to a bonus round that employs a grid configuration. The present invention includes a bonus round configuration having a plurality of groups that each contain a number of elements. The plurality of groups and elements are related in such a way that the bonus round has a decreasing chance of generating an award for the player with each successive random selection of an element from a group. 
   In an alternative embodiment, the groups  188  and elements  190  of the bonus scheme are configured as illustrated in  FIGS. 21  to  24 . As illustrated in  FIG. 21 , the bonus round begins when the player  108  depresses the start button. The game randomly selects an element  192  from a group  194  and awards a bonus value  196  that corresponds to or is associated with the selected element  192 , i.e., a bonus value of 30 as displayed in the award display  116  of FIG.  21 . Once the element  192  is selected, the entire group  194  specifically including the elements of the group that contains this element  192  is spent or exhausted and visually marked as indicated in FIG.  22 . If another group containing any of the elements of the group is selected, the game terminates as discussed below. 
   The bonus round continues and randomly selects an element  198  from another group  200  that also includes the element  192  that was previously selected as further illustrated in FIG.  22 . In other words, because the “B” was selected in the first group, the next element is randomly selected from another group which includes the “B”. If the “B” element is again randomly selected, the game ends because the “B” and the other elements (i.e., A, C, D and E in the group) are exhausted or eliminated. Once the element  198  is selected, a bonus value of 20 (not shown) that corresponds to this element  198  is added to the previous bonus value of 30 for a cumulative bonus value total  202  of 50. The entire group  200  including the elements in the group that contains this newly selected element  198  also is spent and visually marked as illustrated in FIG.  23 . 
   The bonus round continues and randomly selects an element  204  from another group  206  that also contains the previously selected element  198  as further illustrated in FIG.  23 . The newly selected element  204  is highlighted and its corresponding bonus value of 20 (not shown) is awarded and added to the cumulative bonus value total  202  for a new cumulative bonus value total  208  of 70. The entire group  206  that includes the newly selected element  204  is spent and visually marked as illustrated in FIG.  24 . 
   The bonus round continues and randomly selects an element  210  from another group  212  that also contains the previously selected element  204  as further illustrated in FIG.  24 . However, the game ends because the selected element  210  is a terminating element, i.e., an element from the spent or eliminated group  194  as visually marked in FIG.  24 . The bonus value (not shown) that corresponds to this element  210  is not added to the cumulative bonus value total. Thus, the bonus value total  214  is 70 at the end of the game as displayed in the award display  116 . 
   Although the groups are illustrated by a circular boundary  216  as illustrated in  FIGS. 21  to  24 , the present invention is not limited to any particular group display. The group display can be defined by a variety of different boundary shapes, sizes, dimensions and configurations or be hidden from the player. For example, the group boundary can include a square, rectangular, triangle, or other like boundary shapes. 
   The present invention is not limited to the element display as further illustrated in  FIGS. 21  to  24 . The elements are represented by letter symbols, such as, A, B, C, etc., as further illustrated in  FIGS. 21  to  24 . However, the elements can be represented by a variety of different symbols, such as, numbers, characters, figures, or other like symbols. 
   The present invention may include a variety of different sequencing events to randomly select a bonus award that corresponds to an element of a group as illustrated above. For example, the bonus round triggering event is the first event or sequence of the bonus round as illustrated in circle  218  of FIG.  25  and further detailed above. The bonus awards or values for each of the elements are not displayed at game initiation as indicated in box  220 . An element is randomly selected. If the element is from a spent or marked group, then the game ends as shown in diamond  222  and circle  224 . If the element is not from a spent or marked group, then an award is displayed that corresponds to a bonus value associated with the selected element as indicated in box  226 . Another element is randomly selected and its corresponding bonus award or value is added to the current bonus value total and displayed as a new cumulative bonus value total. The bonus round continues to select elements and cumulatively award bonus values until an element is selected from a marked or spent group. 
   The present invention is not limited to the sequencing of events as previously discussed and can include any number and variety of different and suitable sequences in order to facilitate excitement and entertainment for the player. For example, the bonus round may include a risk sequence where the player can risk the award prior to the next selection of an element. If the player risks the award and the next selected element is not previously marked or eliminated, the game continues and provides the player with a higher award. The higher award is greater than the award (i.e., the award associated with the cumulatively awarded bonus values) which the player would have received if the risk had not been taken. 
   However, if the player risks the award and the next selected element is a marked or eliminated element, the game ends and provides the player with a consolation award equaling in value less than the value of the award (i.e., the award associated with the cumulatively awarded bonus values) if the risk had not been taken. 
   The player has the opportunity to risk the award before any or all of the selections of the next selected elements. However, if the player chooses not to risk the award, the game provides the award as previously discussed, that is, the player receives an award associated with the cumulatively awarded bonus values that equals, for example, the sum total of bonus values cumulatively awarded at that stage in the bonus round. 
   While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but on the contrary is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the claims. It is thus to be understood that modifications and variations in the present invention may be made without departing from the novel aspects of this invention as defined in the claims, and that this application is to be limited only by the scope of the claims.
