DESCRIPTION
The present invention relates in general to a gaming device, and more particularly to a gaming device having a wildcard symbol that affects other symbols in a same row, column or set as said wild card symbol, and wherein the game exercises two evaluations in determining the player's award.
BACKGROUND OF THE INVENTION
It is well known in the gaming industry to replace one symbol for another. In video poker, for example, the player discards unwanted cards (or symbols) and keeps desired cards (or symbols). Another well known concept related to symbol changing is the wildcard or wild symbol. A conventional wild symbol normally operates to stand for each and every non-wild symbol of the game, so that the wild symbol produces any win that each non-wild symbol or each combination having that non-wild symbol produces, wherein the combination is created in conjunction with other non-wild symbols.
Referring to FIGS. 3A through 3C, three screens of a central display device 30 (described in FIGS. 1A and 1B) illustrate the known operation of a wild symbol. Screen 30 of FIG. 3A illustrates a wild symbol “W”, a heart and a cherry on one payline or one row of symbols of a slot machine gaming device. If the only non-wild symbols that the game includes are the heart and the cherry, then screens 30 of FIGS. 3B and 3C illustrate the complete effect of the wild symbol “W”. Screen 30 of FIG. 3B figuratively illustrates that the wild symbol stands for or in the place of a heart symbol on the payline or row of symbols. Screen 30 of FIG. 3C figuratively illustrates that the wild symbol stands for or in the place of the cherry symbol on the payline or row of symbols.
It is also known to provide a gaming device that changes one or more non-wild symbols into a wild symbol, whereafter the changed wild symbol stands for each and every non-wild symbol of the game. For example, in a base game of a gaming device having a plurality of reels and displaying a plurality of rows of symbols, known gaming devices can change one or more non-wild symbols on the same reel as a randomly generated wildcard symbol.
Wildcards or wild symbols are well known in base games as well as bonus games of gaming devices. For example, in video poker, a wildcard can stand in the place of any other numbered or face card. A wildcard can turn two sevens into three of a kind. A wildcard can also produce a “straight” in a hand otherwise having four of the set including an ace, king, queen, jack and a ten.
PCT application No. PCT/AU97/00121 entitled, Slot Machine Game with Roaming Wild Card, having a publication date of Sep. 4, 1997, discloses a bonus game example. In this application, a slot machine having a video display contains a plurality of rotatable reels with game symbols. When the player receives a triggering symbol or combination, the game produces a bonus or wild symbol. The bonus or wild symbol moves from game symbol to game symbol temporarily changing the game symbol to a wild symbol. If the change results in a winning combination, the player receives an award.
In known non-bonus gaming systems, i.e., in the base game having a plurality of reels, the games evaluate the effect of a wild symbol one time. Thus, if a wildcard creates a new winning combination on a payline of a known slot machine, wherein the payline already contains a winning combination separate and apart from the new winning combination via the wildcard, the known slot machine will pay the separate winning combination once and the new combination once via the wild symbol. That is, in known games, the reels spin, any winning combinations are paid, and the wild symbols produce additional pays. The games, however, do not perform a total re-evaluation and pay all combinations again.
In general, gaming machines count winning combinations once. That is, when one or more symbols change and potentially create one or more new winning combinations, known games will credit the player for winning combinations prior to the change and then the new winning combinations, but will not repay non-changing combinations on a second evaluation. Gaming device manufacturers constantly strive to develop new games and new and exciting ways to award players.
SUMMARY OF THE INVENTION
The present invention provides a method for evaluating a player's award in a game, wherein one symbol of the gaming device changes into another. Specifically, the present invention provides a new method of evaluating winning combinations of symbols when one or more of the symbols changes and a winning combination exists before the change and a new winning combination exists after the change. The present invention applies to a gaming device having one or more reels, wherein each reel has a plurality of symbols. The present invention also applies to a bonus round of a gaming device, wherein the bonus round displays a plurality of changeable symbols. The present invention further applies to any video card game wherein one card having a symbol or number replaces another of such cards.
The present invention preferably employs a video monitor, wherein the symbols are simulated and changing the symbols includes replacing one simulated symbol with another preferably through an entertaining and exciting method. Alternatively, the present invention can employ a mechanical symbol display having a mechanism to change the symbols or a method to indicate that a symbol has changed.
In one preferred embodiment, the present invention provides a method for evaluating a player's award in a game wherein one wild symbol turns other symbols wild. The method of the present invention involves a two step award evaluation. In one step, the game provides all awards for predetermined symbols and combinations thereof, including winning combinations produced by a wild symbol. If the player receives a winning combination coupled with the wild symbol, the first step pays for both the winning combination and the winning combination coupled with the wild symbol. The wild symbol can function alternatively, such as standing in the place of certain symbols but not in place of each symbol of the gaming device.
In a second step, the game awards all awards for predetermined symbols and combinations thereof produced after the wild symbol has changed one or more non-wild symbols to a wild symbol. This step includes awarding the player for combinations previously awarded in the first step, which may or may not have been the result of the wild symbol. The preferred embodiment applies to symbol generating gaming devices, such as slot machines, as well as video card gaming machines that generate playing cards having number or face card symbols.
In another embodiment, the present invention provides a method for evaluating a player's award in a game wherein one symbol substitutes for or replaces another symbol. The method again involves a two step award evaluation. In one step, the game provides all awards for predetermined symbols and combinations thereof, before the substitution or replacement. In a second step, the game provides all awards for predetermined symbols and combinations thereof produced after the substitution or replacement. This step includes awarding the player for combinations previously awarded in the first step, which remain after the substitution or replacement. This embodiment also applies to slot machines as well as video card games.
It is therefore an object of the present invention to provide a gaming device wherein one symbol substitutes for or replaces another symbol, and wherein the game provides awards for all winning symbols and winning combinations of symbols before said substitution or replacement and for all winning symbols and combinations of winning symbols after said substitution or replacement.
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.

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, such as payline 56, wherein the paylines can be horizontal, diagonal or any combination thereof.
Preferred Method—Slot Machine Embodiment
Referring now to FIG. 4, a well known paytable 100 having a plurality of winning symbol combinations that will aid in the description of the present invention is illustrated. All gaming devices, including slot, poker and other card machines include some form of winning symbol list or paytable that informs the player of symbols or symbol combinations that produce an award for the player. On gaming device 10b, for example, the upper display device 32 can contain the paytable. Paytable 100 includes: a winning combination 102 of two cherries that yields five credits to the player; a winning combination 104 of two hearts that yields ten credits to the player; a winning combination 106 of three cherries that yields fifty credits to the player; and a winning combination 108 of two hearts and a cherry that yields one hundred credits to the player.
Referring now to FIGS. 5A and 5B, one preferred method of the present invention is disclosed in a slot machine embodiment. FIGS. 5A and 5B both include the central display device 30, three reels 34a, 34b and 34c and three paylines 56a, 56b and 56c. FIGS. 5A and 5B illustrate a plurality of randomly generated symbols, some of which, namely the heart and the cherry, are located on the paytable 100 of FIG. 4. The paytable 100 of FIG. 4 is to be used in conjunction with the description of FIGS. 5A and 5B.
FIG. 5A also includes a preferably randomly generated wild symbol 110 shown as a “W” on reel 34b and payline 56a. FIG. 5B illustrates that the game of the present example maintains a feature whereby the randomly appearing wild symbol 110 on the central display device 30, as indicated by FIG. 5A, in turn replaces or substitutes for every display symbol on the wild symbol's associated reel, 34b, as indicated by FIG. 5B. The preferred method of the present invention evaluates the player's winnings, according to a predetermined paytable, in two steps.
In a first step, one preferred method of the present invention evaluates or finds all winning symbols and symbol combinations before the wild symbol replaces or substitutes for any other symbols. The wild symbol 110 on reel 34b and payline 56a of FIG. 5A preferably has the effect described above in FIGS. 3A and 3B. The wild symbol stands in the place of a cherry symbol and/or a heart symbol. Along payline 56a, then, the player wins fifty credits for the three cherries appearing on the reels 34a, 34b and 34c. Paylines 56b and 56c produce no winning combinations.
The first step of the method of the present invention provides fifty overall credits to the player. It should be appreciated that the first step can alternatively not give the wild symbol the effect described in FIGS. 3A and 3B, namely to stand in the place of all non-wild symbols, and still award credits for any award generating non-wild symbol or combinations. It should also be appreciated that the implementor of the present invention can design one or more reels or otherwise design a game wherein the player is guaranteed or predetermined to obtain one or more wild symbols. For instance, in FIGS. 5A and 5B, the implementor can place a wild symbol 110 on every third position of a reel, so that the player is guaranteed to receive one wild symbol 110 on that reel. It should further be appreciated that the present invention contemplates any award including but not limited to credits, multipliers, a number of picks from an award set or any combination thereof.
In a second step, one preferred method of the present invention evaluates or finds all winning symbols and symbol combinations after the wild symbol 110 replaces the other symbols. The wild symbol “W” on reel 34b and paylines 56a, 56b and 56c of FIG. 5B have the effect described above in FIGS. 3A and 3B. Along payline 56a, as before, the player wins fifty credits for the three cherries appearing on the reels 34a, 34b and 34c. Along payline 56b, the player now wins 100 credits for the two hearts and a cherry appearing on the reels 34a, 34b and 34c. Along payline 56c, the player now wins ten credits for a heart—heart combination appearing on reels 34a and 34b. 
The second step of the method of the present invention provides 160 overall credits to the player. Both steps provide 210 credits to the player. It should be appreciated that any award produced in the first step is included or counted again in the second step along with any new winning symbol or symbol combinations produced by the expanding wild symbol. In this example the awards produced along payline 56a are included or counted again in the second step.

FIG. 13 also includes a preferably randomly generated wildcard, which is one of the playing cards. The game can assign one or more of the cards to be a wildcard at any point of the game. In this example the game has preferably randomly determined but alternatively predetermined that all aces are wildcards, as indicated by the message 124. The game can give any suitable desirable effect to a wildcard, however, the game preferably gives the known poker effect to a wildcard. That is, the game enables the wildcard to adopt or equate to any desired playing card value or symbol. The game can automatically and optimally determine which value or symbol with which to equate a wildcard. The preferred method of the present invention evaluates the player's winnings, according to the paytable 112, in two steps.
In a first step, the preferred method of the present invention evaluates or finds all winning playing card and playing card combinations before the game activates or equates the wildcard to a particular playing card. According to the paychart 112 of FIG. 12 and the hand 122, the player wins five credits for a two of a kind winning combination 114 for the two twos and five credits for a two of a kind winning combination 114 for the two aces. The first step of the method of the present invention provides ten credits to the player.
In a second step, the preferred method of the present invention equates the wildcard to one of the other non-wild cards of the hand 122. Since the wildcard preferably equates to only one other card, the player or game must in the second step optimally decide which non-wildcard of the hand 122 with which to equate. Since aces are wild in the hand 122, the game or player can equate the two aces to the eight of diamonds and create a full house winning combination 118 including three eight's over two two's. Alternatively, the game or player can equate the two aces to the two's (of spades and of hearts) and create a four of a kind winning combination 120. Since, according to the paytable 112 four of a kind 120 pays better than a full house 118, the game or player preferably equates the two aces to the two's.
In the second step, the player obtains 100 credits for the four of a kind winning combination 120. Overall, the player wins 110 credits in the poker game employing the preferred method of the present invention. FIG. 13 discloses the preferred wildcard effect for the method of the present invention in a poker machine embodiment, wherein the wildcard equates to one of the other non-wild cards of the hand 122. The present invention can alternatively equate the wildcard to each non-wildcard of the hand 122. In this embodiment the game provides a plurality of second step awards: (i) 100 credits for four two's, and (ii) 50 credits for the full house eight's over two's.
The draw poker game preferably contains one or more card exchanges, wherein the game enables the player to keep certain cards and discard others. That is, the player can for example keep a pair of kings and a wildcard and discard a four and a two. The game will issue two new replacement cards. The game can then enable another card exchange. The evaluation method applies to a draw poker game having a card exchange the same as described above. After the game enables the player to exchange cards, the game employs the evaluation sequence by: (i) providing an award for winning card combinations present before activating or equating the wildcard; and (ii) providing an award for winning card combinations present after activating or equating the wildcard.
Most poker games do not, and likewise the poker game of the present invention preferably does not provide a separate award for a full house and its constituent three of a kind and two of a kind. Likewise, poker games generally do not pay for one, four of a kind and two, two of a kind combinations. That is, in the alternative embodiment, the game equates the wildcard to each non-wildcard but preferably does so for one, the most profitable, winning combination.
Alternative Method
Referring now to FIGS. 14A and 14B, the present invention contemplates an alternative embodiment, illustrated here in connection with a slot machine embodiment, wherein the game replaces one or more symbols with one or more different symbols. That is, the replacement is not a wild symbol. The alternative method still applies a similar two step evaluation, wherein the game adds all awards from winning symbols or symbol combinations before the replacement to all awards from winning symbols or symbol combinations after the replacement.
The paytable 100 of FIG. 4 applies to and is used to describe the alternative slot machine method of the present invention including a central display device 30, three reels 34a, 34b and 34c and three paylines 56a, 56b and 56c. In this example of the present invention the heart symbol replaces a “7” symbol. In the first step of the evaluation, the player wins 50 credits for obtaining three cherry symbols along payline 56a. The game then replaces each “7” with a heart symbol, which results in the screen of FIG. 14B.
In the second step evaluation, the player again wins 50 credits for obtaining three cherry symbols along payline 56a, 100 credits for the heart—heart-cherry combination on reels 34a, 34b and 34c of payline 56b and 10 more credits for the heart—heart combination on reels 34b and 34c and payline 56c. The total for the second step evaluation is 160 credits and the total for the alternative slot machine embodiment round is 210.
Referring now to FIGS. 15A and 15B, the present invention contemplates the alternative embodiment in connection with the poker game, wherein the game replaces one or more playing cards with one or more different playing cards. That is, the replacement is not a wildcard replacement wherein one card of a hand adopts or equates to another card of a hand. In FIGS. 15A and 15B, which are evaluated in conjunction with the paytable 112 of FIG. 12, one of the displays 30 or 32 includes a hand 126 and a message 128 indicating that an ace of a suit is replaced by an eight of the same suit.
FIG. 15A includes the initial hand 126 including an eight of diamonds, a two of spades, a two of hearts, an ace of clubs and an ace of diamonds. In the first evaluation of the alternative embodiment, the player receives five credits for the two of a kind two's and five credits for the two of a kind ace's, according to FIG. 12, for a total of 10 credits. For the second evaluation every ace is replaced by an eight of the same suit. The ace of clubs changes to the eight of clubs and the ace of diamonds changes to the eight of diamonds. The player therefore receives 50 credits for a full house eight's over two's, according to FIG. 12. The game contemplates enabling two of the same card to exist in one hand at the same time, e.g., two eight of diamonds as illustrated in FIG. 15B. The player again preferably does not win constituent combinations in the poker embodiment. The total win for the alternative method poker embodiment is 60 credits.
It should be appreciated that in both the alternative slot and poker embodiments, more than one symbol can replace more than one different symbol as desired by the implementor. In the alternative slot embodiment for example, a heart can replace a “7” and a cherry can replace a bar. In the alternative poker embodiment, the ace of a suit can be replaced by the eight of the same suit and the king of a suit can be replaced by the two of the same suit.
While the present invention is described in connection with what is presently considered to be the most practical and preferred embodiments, it should be appreciated that the invention is not limited to the disclosed embodiments, and is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the claims. Modifications and variations in the present invention may be made without departing from the novel aspects of the invention as defined in the claims, and this application is limited only by the scope of the claims.
