This application is related to U.S. patent application Ser. No. 10/106,992, filed on Mar. 26, 2002, and also U.S. patent application Ser. No. 09/819,152, filed on Mar. 27, 2001, both of which are incorporated herein by reference in their entireties.
BRIEF DESCRIPTION OF THE INVENTION
This invention relates to gaming machines. More specifically, this invention relates to a method and apparatus for previewing a game on a gaming machine.
BACKGROUND OF THE INVENTION
Modern casinos and other gaming establishments often overwhelm players with the number and type of gaming machines available. Potential users or players of gaming machines are often given a choice of games such as slot machines, video poker, keno, blackjack, and many other games of skill and/or chance. Presented with a multitude of unfamiliar games, players often play only a select few favorites, or simply do not play any at all. This situation is exacerbated by the fact that most games require money to play. Thus, even if a game is potentially appealing to players, they often will not spend money to try an unfamiliar game, with the result being a loss of business to the gaming establishment and/or slow introduction of new machine types.
Methods of attracting players to unfamiliar games on unfamiliar gaming machines thus would help gaming establishments attract further business. In addition, players benefit by gaining access and familiarity to a wider variety of games, many of which they may not have been familiar with. It is therefore desirable to develop ways to allow players to preview games, so as to introduce them to those games that may have previously been unfamiliar to them.
SUMMARY OF THE INVENTION
Broadly speaking, the invention pertains to previewing a game on a gaming machine. A portable sample play device, such as a player tracking card or other player-carried device, allows players or users of a gaming machine to view, and/or participate in, sample or preview play of a game. The portable sample play device can be a smart card that stores all necessary information itself, or a known magnetic stripe card that simply stores rudimentary information such as an identification number. Additionally, such a sample or preview can include many different modes of play. For instance, the gaming machine can display a preview of link progressive play, along with the progressive jackpot. It can also display the special bonus modes of various games, demonstrating to the player various special prizes than can be won. Such preview play can be interactive, allowing player participation, or passive, simply illustrating sample play without allowing user interaction. Preview play can also include full, nominal, zero, or other payouts if so desired.
The invention can be implemented in numerous ways, including as a method, system, device, and apparatus. Several embodiments of the invention are discussed below.

DETAILED DESCRIPTION OF THE INVENTION
In one embodiment of the invention, a player is given a portable sample play device, such as a tracking card, that allows the user to preview a new game on a gaming machine. Information stored in the sample play device prompts the game machine to display a preview of the game, familiarizing the user with a new and unfamiliar game, and perhaps displaying to him/her the potential prizes that can be won. In this manner, players are given a new vehicle for learning about unfamiliar games, allowing gaming establishments to perhaps gain revenue from game machines that would have otherwise been neglected by players, and players to find more, and more interesting, games to play.
FIG. 1 illustrates a gaming machine system configured to operate in accordance with an embodiment of the invention. The gaming machine system 10 includes at least one gaming machine 20 at a particular location, remote gaming machines 30 at another location, a bus 40, and a back-end server 50. The gaming machines 20, 30 and the back-end server 50 communicate with each other electronically via the bus 40, which is simply a known data transmission line. Each gaming machine 20, 30 is a known device capable of allowing a player to play a game, and dispensing rewards, monetary or otherwise, as appropriate. The configuration of the gaming machine system 10 encompasses embodiments in which the back-end server 50 controls the operation of the gaming machines 20, 30. The system 10 also encompasses embodiments in which the gaming machines 20, 30 are each stand-alone units capable of operating play of their games largely without the back-end server 50. Like gaming machine 20, gaming machines 30 are configured to allow a player to play a game. The gaming machines 30 are shown as separate from gaming machine 20 simply to illustrate the fact that various embodiments of the invention can be utilized within systems 10 that have multiple networked gaming machines.
Also included in the system 10 is a portable sample play device 60 that can be carried by players. The sample play device 60 can be a known player tracking card that stores information. In such a case, the gaming machine 20 can be equipped with a known card reader, allowing players to insert their tracking cards into the gaming machine 20 to be read before or during game play. The sample play device 60 can be any device that can be carried by a player and that can store information. As discussed above, it is often convenient for the sample play device 60 to be a player tracking card, as such cards are known and widely used by players already. FIGS. 2A-C illustrate two different types of player tracking cards, each capable of being used in connection with the invention. FIGS. 2A-B illustrate an exemplary “smart” player tracking card 100 having contacts 110 on its outer surface, as well as internal components including a microprocessor 120 and memory 130. The microprocessor 120 and memory 130 are in electronic communication, allowing the microprocessor 120 to store information in, and retrieve information from, the memory 130. The microprocessor 120 is also electrically connected to the contacts 110, allowing it to interface with external devices and systems.
In the operation of a gaming machine system 10 utilizing smart cards 100, players insert their tracking cards 100 into a gaming machine 20. The microprocessor 120 then retrieves information from the memory 130 and transmits it to the gaming machine 20. The information can include such items as time information indicating how much sample play time remains, as well as various parameters of the sample game, and perhaps identification identifying the player. Receipt of this information prompts the gaming machine 20 to initiate a preview of the game.
FIG. 2C illustrates an exemplary magnetic stripe tracking card 140. In contrast to the smart tracking card 100, the magnetic stripe tracking card 140 does not contain a microprocessor 120. Instead, its magnetic stripe 150 stores a relatively small amount of information, such as an identification number, that can be read by a known card reader. Operation of a gaming machine system 10 utilizing magnetic stripe tracking cards 140 typically requires the presence of the back-end server 50 to provide information that cannot be stored on the card 140. Commonly, the gaming machine 20 automatically retrieves an identification number stored on the card 140, and sends it to the back-end server 50. The back-end server 50 checks the identification number to determine whether the user of that particular card 140 is entitled to sample play and, if so, initiates sample play on the gaming machine 20.
As discussed above, the sample play device 60 can be any device capable of being used by a player, and also capable of storing information. As such, the invention is not limited to the tracking cards 100, 140 described above. Rather, any device capable of storing information can be employed. For instance, payment tickets such as those used in the EZ Pay® system produced by IGT can be simply printed tickets that show a monetary amount to be paid to a player. Such tickets can be modified to include information for implementing the various embodiments of the invention, such as the information stored on the tracking cards 100, 140 to govern preview play.
Attention now turns to a more detailed explanation of this process by which the smart tracking cards 100 are used to initiate a sample or preview game on gaming machines 20, 30. FIG. 3 illustrates a flow diagram, in accordance with an embodiment of the present invention, that allows a player to preview a game on a display of a gaming machine by using a smart player tracking card. As mentioned, the information stored within the smart card 100 can render the back-end server 50 unnecessary for many tasks, often allowing the game machine 20, 30 to carry out many aspects of sample play by itself The smart card 100 is first inserted into, or otherwise placed in electronic communication with, a gaming device 20 (step 200). Stored in the memory 130 is a flag or other information indicating whether the player in possession of this particular smart card 100 is allowed preview play, as will be described below. The gaming machine 20 reads this information (step 210), and if the player is not allowed preview play, the session ends (step 300).
However, if preview play is allowed, the various parameters of preview play are read (step 220), and the gaming machine 20 sets up preview play according to these parameters (step 230). The parameters, then, are basically instruction sets that govern play of this game. For example, the parameters can include paytable values that indicate how much payment, if any, could be awarded to the player upon a favorable outcome such as a winning card hand. The parameters can also include such things as a predetermined set of outcomes, or a specified percent chance of winning. Thus, the smart card 100 can instruct a gaming machine 20 to display preview play in a manner indicating a higher incidence of winning, so as to promote player interest and attractiveness. The card 100 can also set up preview play illustrating a specific sequence of outcomes, so that in a slot game, for instance, the player is guaranteed to see a four King outcome, or in video poker, the player is guaranteed to be dealt a full house. Such favorable outcomes make the game more attractive to the player, in part by demonstrating possible outcomes of interest to the player. Text or other indicators can also be displayed, tending to highlight the fact that game play can result in such favorable outcomes. Those of skill will recognize that the smart card 100 can store these and other parameters, allowing for sample game play that is configured in any desired manner.
Once preview play is set up according to the parameters stored in the smart card 100, preview play is initiated (step 240). As discussed above, this preview play can be interactive, permitting players to play hands of video poker or play a slot game, for instance. Preview play can also be passive, with the various parameters instructing the gaming machine 20 to simply show players, for example, card hands they could have been dealt or slot machine outcomes they could have received.
If a player wins, or is shown a winning outcome (step 250), the gaming machine 20 determines the appropriate award from the paytable (step 260), and presents that award to the player (270). Often, it is desired that preview play merely demonstrate to players how to play the game, and does not illustrate any monetary rewards. In these situations, the parameters stored on the smart card 100 include paytable values of zero, instructing the gaming machine 20 not to award any money to the player.
To further entice players, however, the smart card 100 can also include information instructing the gaming machine 20 to apply its “normal” playtable(s) to determine and display what reward the player could have been awarded had they actually played the game.
The smart card 100 can also store information indicating whether preview play should end at some point. For example, the smart card 100 can store time information indicating how long preview play should continue before it terminates, or information indicating how many hands, rounds, or the like can be played. In these cases, the gaming machine 20 checks to determine whether play should be ended (step 280). Preview play can also be ended voluntarily if the player desires. If either of these situations occurs, the gaming machine 20 updates the preview play information to indicate how much, if any, preview play remains (in the case that preview play time has expired, or the specified number of hands/rounds/etc. has been played, that time would be zero) (step 290), and play ends at step 300. If play is to continue, the process returns to step 240 instead.
In contrast to the process illustrated in FIG. 3, FIG. 4 illustrates process steps that enables a player to preview a game by using a magnetic stripe player tracking card 140 in accordance with an embodiment of the invention. As previously discussed, a magnetic stripe card 140 can only store a small quantity of information such as an identification number. The presence of the back-end server 50 is thus typically required in combination with the application of the magnetic stripe card 140.
Once the magnetic stripe card 140 is entered into the gaming device 20 (step 310) and the identification number is read (step 320), the back-end server 50 is contacted (step 330). If contact cannot be made, the process terminates (step 420). However, if contact is made, the gaming device 20 transmits the identification number to the back-end server 50.
The back-end server 50 maintains a list of identification numbers that are authorized to initiate preview play, as well as all parameters for configuring the appropriate preview play. The back-end server 50 then checks the received identification number against its list (step 340). If the identification number does not match any on the list, preview play is unavailable for that card 140, and the process ends at step 420. If a match is found, preview play is available for the holder of that card 140. The parameters for preview play are then retrieved, and preview play is set up accordingly (step 350). The back-end server 50 then initiates preview play 360 according to these parameters. Again, as above, such parameters are simply the parameters of the game to be played, such as the outcomes or the rewards to be paid.
Once preview play is initiated (step 360), the player may be allowed to participate interactively, or may simply be a passive witness to preview play of the game. Either way, winning outcomes may or may not be achieved (step 370). If a win occurs, the back-end server 50 consults its paytable (which may or may not have been modified according to the appropriate parameters) to determine the appropriate reward (step 380). This reward, if any, is then presented to the player (step 390). As mentioned, the award may be merely an indication of the what the player could have received had they achieved a similar outcome when playing the game outside of preview play.
At various points in the game, such as after an electronically generated hand of cards or an electronic die roll, or after a specified amount of time (stored on the back-end server 50) has elapsed, play may be ended (step 400). If it is not, then the process continues to step 360 and preview play continues. If preview play is to end, preview play information on the back-end server 50 is updated, perhaps to update the amount of preview play time allotted to the holder of the card 140, or to log the awards paid to the holder of the card 140 (step 410), and preview play ends at step 420.
In connection with the process steps of FIG. 4, it should be noted that certain embodiments of the invention allow the back-end server 50 to fully execute game play, with the gaming machine 20 being simply a dummy terminal that displays the game as executed by the server 50. As servers 50 can be configured to run more than one game, it follows that each gaming machine 20 can, in some embodiments, display more than one game. More specifically, even though a gaming machine 20 typically displays a first game, insertion of the tracking card 140 may initiate the display of a preview of a second game. For example, a gaming machine 20 can typically display a video poker game, and may even be advertised as a video poker machine. However, a card 140 may store an identification number corresponding to preview play of a slot game. In embodiments corresponding to FIG. 4, the back-end server 50 may be configured to run both video poker and slot games. Accordingly, upon insertion of the card 140 into the video poker game, preview play of a slot game may could be initiated instead. One of skill will realize that the invention therefore encompasses the initiation of preview play of games that are different from those normally played on a particular gaming machine 20.
One advantage of the invention is that it permits players to preview a previously unfamiliar game by simply inserting their tracking card into a game machine. In this manner, gaming establishments have a convenient platform to offer new games to their customers, and players have an opportunity to sample play of these new games with little or no cost.
FIGS. 5-7 illustrate an example of preview play, so as to further demonstrate novel aspects of the invention. In this example, regular game play of the slot game is explained, and preview play is then shown in contrast. In conventional play of a slot game, players either pull a handle or press a button to commence spin a number of reels. When each reel stops spinning, it displays a number or symbol as an outcome. For example, one spin of a five reel slot machine may produce a Queen—Nine—Ten—Ace—Money Symbol. Desired outcomes, such as Ace—Ace—Ace—Ace—Ace, may produce monetary rewards.
Commonly, slot games store a numerical value associated with each position on each reel. This can be represented by the table of FIG. 5, where for a typical five reel slot game, each symbol 500 is assigned a number 510. Accordingly, typical parameters of such a slot game include a series of randomly or pseudo randomly generated numbers corresponding to numbers 510 that dictate game outcomes, as well as a paytable 520 for determining the reward or payout associated with each outcome. In operation of a five reel slot machine, players initiate play by pulling the slot machine handle or pressing a button. This randomly generates a set 530 of five numbers 510, here shown as 15, 3, 10, 30, and 21, in FIG. 6. Each number 510 is then matched to its corresponding symbol, using the Game Instruction Table of FIG. 5. For instance, the number 15 corresponds to the first reel displaying a “10.” As can be seen from the table, the numbers 15, 3, 10, 30, and 21 correspond to the five reels displaying results 540 of, in order, Ten, King, Eight, Queen, and Ten. Consulting the paytable 520, the payout value 550 for the results 540 is two dollars.
In one example of preview play, the paytable 520 is set to small values to provide the player a preview of what he or she could win, without excessive cost to the gaming establishment. The randomly generated results 530 are also replaced with preset values so that the player can witness some of the more favorable outcomes he or she may receive. In accordance with the process steps outlined above, players simply approach a game machine 20 with their player tracking card. Whether the tracking card is a smart card 100 or a simple magnetic stripe card 140, it can be configured to initiate play of a slot game. Parameters of the slot game, which are either stored on the smart card 100 or a back-end server 50, are retrieved and the slot game is configured accordingly. Specifically, the paytable 520 is wiped and its values are replaced with preset nominal values. The preview play paytable 600 is thus populated with much smaller values. One or more sets of predetermined results 610 are also utilized. When the player pulls the slot machine handle or presses the appropriate button, the set of predetermined results 610 is matched to the table of FIG. 5 to determine the resulting symbols 620 seen by the player. In this example, the set of predetermined results 610 consists of 9, 17, 12, 6, and 31, resulting in symbols 620 of Money Symbol—King—Money Symbol—King—King. This obviously favorable outcome results in a nominal payout value of one dollar. Preview play can then continue, with further result sets 610 producing other outcomes.
As can be seen, the parameters retrieved and used in sample play of a slot game include dollar values for paytables 600, and one or more sets of predetermined results. It should be noted that the invention is not limited to use of particular values of these parameters. For example, other dollar values for paytable 600 can be employed. Commonly, zero values can be used if preview play is intended simply to illustrate how the game is played, rather than to present a reward. The invention is also not limited to the parameters shown. Preview play may include randomly generated results rather than predetermined results 610, although predetermined results 610 are often desirable to show users some of the better outcomes and potentially larger jackpots.
In the example of FIG. 7, players are an active participant in preview play, pulling handles or pressing buttons themselves to initiate game play. However, as discussed previously, the invention can also allow players to be passive observers. It should be clear that, once the player inserts his or her tracking card, the preview play of FIG. 7 can be run automatically, with the player simply observing how the game is played.
Likewise, the invention is also not limited to display of the outcomes shown. Rather, any display of outcomes is contemplated. Thus, the parameters need not include preset results. Randomly generated results can be employed to give players a sense of what typical game play entails. Conversely, the results can include sequences of some of the more desirable game outcomes (e.g., several good poker hands, big slot jackpots, and the like), so as to entice the player to play.
The invention is also not limited to the slot game context. Rather, various embodiments of the invention can be used to illustrate preview play of any game capable of being played on a game machine 20, 30. For example, preview play can be of a video poker game or a blackjack game. Similarly, the invention can illustrate many different preview play modes of a single game. For instance, while the preview play of FIG. 7 illustrates a single player slot game, preview play can also be used to highlight link progressive play of multiple networked games. It is known that link progressive play involves multiple players playing games on networked gaming machines 20, 30 that each pay into a single jackpot. Each player then has a chance of winning all or part of this common jackpot, which due to the number of players can be larger than the typical jackpot from a single machine 20. The invention thus encompasses preview play of link progressive games, where the player is shown the current common jackpot value along with a preview of the game. Such previewing of link progressive play may educate players as to the potential rewards of progressive games, thus encouraging them to play.
The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the invention. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the invention. In other instances, well-known devices are shown in block diagram form in order to avoid unnecessary distraction from the underlying invention. Thus, the foregoing descriptions of specific embodiments of the present invention are presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. For example, the invention contemplates preview play of any game capable of being played on a game machine, either by smart card or simple magnetic stripe tracking card. The invention also includes multiple modes of preview play, including but not limited to displays of typical game play, predetermined sequences of more favorable outcomes, and progressive play. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the following claims and their equivalents.
