1. Field of the Invention
The present invention relates to casino games and, more particularly, to casino games having bonusing features.
2. Background
Casino bonusing games are increasingly popular when placed in operation with underlying casino gaming machines such as, for example, slot machines. Such bonusing games not only attract players but provide additional gaming excitement. In the play of such casino bonusing games, instructions on how to play the bonus game are usually placed on the face of the machine or can be read by a player in a display through suitable “help” input signals such as on a touch screen, a separate button, etc. The same is true of the underlying casino game wherein a player has the ability to obtain instructions for the play of the game. By following the instructions, the player is informed of the play characteristics of both the underlying casino gaming machine and/or the casino bonus game.
UK Patent Application GB2262642A describes a fruit machine with a “special status mode” in which an indicator alerts the player to a “secret” feature. In this mode, a non-explanatory indicating sign, e.g. a light, appears on the display screen, and usually the display screen gives no instructions as to how to obtain an award. A special sequence of inputs, e.g. button pushes, is required to obtain an award. The '642A reference describes a “secret” feature whose presence is not really secret because it is known to the player (i.e., by use of the indicator). But what is secret is how the player should properly respond when the indicator is illuminated (i.e., pushing a special sequence of multiple button pushes). Hence, the proper time at which to enter the button sequence is not kept secret, but the secret lies in “cracking the code” of what to do to achieve the award. Stated another way, the '642A reference informs a player by an illuminated indicator that a bonus opportunity exists, but the player must figure out by guessing what to do. While interesting to players, this approach has the disadvantage of frustrating players who know they ought to do something, but then repeatedly err while trying to crack the code. In conjunction with the British adaptive logic approach (in which odds/payoffs for subsequent game trials are adaptively dependent on previous results), this approach has the undesirable side effect of potentially frustrating poor players (who by virtue of not knowing what to do, will see the “secret feature” more often, enhancing and reinforcing feelings of failure) while also potentially frustrating the good players (who by virtue of winning more with the “secret feature,” are apt to see the feature less often, leading to aggravation while waiting to see the feature again).
A need therefore exists to provide enhancements to hidden bonus features in an underlying casino gaming machine and/or even in a casino bonus game to further award the player in a surprise fashion without providing any instruction on how to play the hidden bonus feature on the face of the machine or in any help instructions for play of either casino game. A further need exists for gaming machines that are operated under strict U.S. guidelines in which the selection of game trial outcomes are independent events, and not adaptive in nature.
A need also exists for hidden bonus features to be provided without any separate indicators alerting the player to their presence. A need exists for hidden bonus features to be secret but once discovered, simple enough so that a player need not memorize complex inputs to be awarded a prize. By combining and fulfilling these needs, different kinds of players may be accommodated and provided a rewarding experience. In particular, poor players, by virtue of not recognizing the hidden bonus feature, are not therefore frustrated at “not knowing what to do,” while good players, as they succeed in finding and obtaining the hidden awards, are not penalized by decreased frequencies of winning, etc.
A need exists to make the value of the hidden bonus feature a function of the time taken to react to it. A need exists to make the hidden bonus feature awards random as a means of keeping player suspense even once the hidden bonus feature is identified.
The present invention solves the aforesaid problem by providing a hidden bonus feature in a casino game such as an underlying gaming machine or an underlying game having a casino bonus game without providing any external or separate indicator and without providing information concerning how to play and/or respond to the hidden bonus feature on the face of the casino game or in association with the instructions for the play of the casino game.
A method is set forth for further awarding a player of a casino game. The player normally plays a casino game. During play of the casino game, a hidden bonus feature occurs such as through a display. The hidden bonus feature may occur at a random statistical frequency or other event, so that the hidden bonus feature suddenly occurs. While the existence of the hidden bonus feature may be made known to the player, there is no indicator and no instructions or information concerning how to respond to this hidden bonus feature on the face of the casino game or in any play instructions for the casino game. Upon display or occurrence of the hidden bonus feature, the player must then provide a correct response and when a correct response is received, the player receives an additional award. If a correct response is not received, the player does not receive any further award.
The microprocessor 20 is usually connected 28 to a random number generator (RNG) 50 which may be a separate hardware component or a software module within memory 60. The microprocessor 20 is interconnected 24 to memory 60 and interconnected 72 to display 70 showing slot reels 94a, 94b and 94c. Slot machine 10 is shown in functional block diagrams and conventional devices, ports, busses, buffers, etc. are not shown.

It is to be expressly understood that in some designs for the hardware of the present invention, microprocessor 120 can drive over 22 the display 110 without using a separate display processor 20 and display memory 130. For example, in a video poker gaming machine 10, the display 70 could display play of the underlying gaming machine 100a with the occurrence of a hidden bonus in the same display 70 under control of the microprocessor 20. The method of the present invention as set forth in the following works with a casino game using a single display such as only display 70 in

The bonus condition can be any suitable bonus condition and is not limited to a bonus symbol 80 appearing on the pay line 90. Whatever causes a bonus condition to occur in the play of the underlying game 100a causes play of the casino bonus game 100b (either in a separate display 110 as shown in
The hidden bonus feature 200 of the present invention is shown in
The term “casino game” is defined herein to include any gaming machine 10, underlying gaming machine 100a having a bonus game 100b implemented with a computer-based control 20 such as illustrated with a microprocessor in
The hidden bonus feature 200 starts 300, in one embodiment, at the same point in time or at different times in the casino game, but whether it occurs can also be determined at a random statistical frequency based on the input from the random number generator 50 as shown in FIG. 3. The occurrence of the hidden bonus feature can be, in another embodiment, based on an event 302. For example, such an event 302 may occur when the player wins 100 credits or more in the underlying casino game. Or, the event 302 may occur when a game symbol 92 or combination of symbols 92 appear in play of the casino game. The occurrence of the hidden bonus feature 200 is vigorous and is not limited to the above embodiments. Any event 302 that invokes the occurrence of the hidden bonus feature 200 can be used. As additional examples, but not meant to limit the invention, the event 302 can be triggered on a given or randomly selected number of coin-ins to the underlying game; on a given or randomly selected number of bonus game 140 plays; on a given or randomly selected number of credits won in the underlying game (whether or not it is the same player); on the occurrence of a given timed period, given time of the day, or randomly selected time period or time of day; etc.
In one embodiment, nothing is displayed at all to the player when the hidden bonus feature 200 occurs. In this embodiment, the hidden bonus feature 200 may be a function of the outcome of the casino game (i.e., game outcome). In an example of a slot casino game, the hidden bonus feature 200 occurs with a predetermined combination (or alignment) of a game symbol 92 or game symbols 92 as an event 302, such as, by way of an example, four watermelons (not shown). In which case, the award for the hidden bonus feature 200 is obtained by the player touching the fourth watermelon to receive 2× the standard payout. The response 310 from the player is the touching 370 of the fourth watermelon on the touch screen display 70. If the player touches 370 any other watermelon or symbol 92 nothing happens as these are incorrect responses. Likewise, if the player wagers and spins the reels 94 again, this is an incorrect response 310 for the hidden bonus feature 200. What the hidden bonus feature 200 is and/or how to respond is not known to the player. In the above watermelon example, the player does not know from any instructions for play of the casino game that the hidden bonus feature 200 is “four watermelons” or that the player must touch 370 the “fourth watermelon” to receive the 2× (or whatever the desired bonus is). In one variation, the player responding 310 in an incorrect manner (e.g., by touching the second watermelon) negates the feature. In another variation, an incorrect response 310 on the part of the player does not negate the feature, which remains eligible to be “discovered” and is only negated when the reels 94 are again spun to initiate the next play on the machine (e.g., causing any pre-determined time period timer to immediately time out) or when a pre-determined time period times out. This is shown by dotted lines 372 in FIG. 3. The time it takes for a player to input 370 after the hidden bonus feature 200 occurs, in a variation, results in a higher payoff to the player in step 330. In this variation, the method would start a timer and measure the amount of time for the correct response 310 to be input 370. The method, either in a look-up table or a software determination, would then provide a higher award 330 for a faster input 370 resulting in a correct response 310.
In another variation, when the four watermelons line up, the hidden bonus feature 200 may be to touch the fifth symbol on that line or to touch any non-melon, etc. The hidden bonus feature 200 then becomes touching this other symbol which may turn into a melon, etc. Or, it may be to touch any non-melon symbol whose position becomes wild, etc. It is to be understood that many variations and other embodiments can be utilized and the examples presented herein do not limit the scope of the present invention. The watermelon example is but one of many. Additional examples of events 302 based on game outcomes are: a card combination in a casino card game (e.g., three aces), a number combination in a video keno casino game (e.g. appearance of “7, 17, 27”), etc. Again, the player input 370 is also vigorous. In the case of three aces, touching any ace, the first ace, the last ace, or simply the screen 70 can be selected as correct responses 310 under the teachings of the present invention.
In another variation, the hidden bonus feature 200 can occur when an event 302 is combination of game symbols 92 that happens during play of a casino game such as, for example, when a card combination is initially dealt to a player such as in a video poker game. Here, for example, the hidden bonus feature 200 occurs when the combination initially dealt to the player has two red queens (i.e., the event 302). The correct response 310 from the player is to touch 370 either red queen. The predetermined game symbols as events 302 in a casino game can be one, two, or any suitable number. For example, in a Wild Deuces video poker casino game, the hidden bonus feature 200 can be a single jack which can appear as the event 302 in the initial hand or any subsequent cards dealt. The player's correct response 310 would be to slap the jack, by touching 370 the card, to receive an award 330. The event 302 based on a symbol or combination of game symbols can occur “during play,” that is, at any time from the start to the end of the casino game. the slot feel reels 94 to start turning, while the reels 94 are spinning, or after the reels 94 stop. In the case of the casino bonus game 100b of
In reference to
The occurrence of the hidden bonus feature 200 in display 70 or 110 occurs as follows when based on randomness 300. The microprocessor 20 upon receiving the random number input 28 from the random number generator 50 activates the hidden bonus feature 200. During all play over time of the casino game, the occurrence of the hidden bonus feature 200 is random. Any of a number of different types of random number generator programs and hardware devices 50 could be used under the teachings of the present invention. As before, when the hidden bonus feature 200 occurs, the player is given an opportunity to respond 310 through a player input device 370. The player input device 370 can be any number of conventionally available input devices. For example, player input 370 could be incorporated in the touch screen display 110 at a suitable location such as touching the display of the hidden bonus feature 200. Or, it could be located on the gaming machine 10 or the underlying gaming machine 100a as a separate input device 370 shown in dotted lines in
When the player response 310 is not correct, the hidden bonus feature 200 is over and, in one embodiment, the casino game resumes 340. In another embodiment, the casino game continues while the hidden bonus feature 200 is still displayed. If the player response 310 is correct, then the player is awarded 330 such.
In the play of the method shown in
In another embodiment, the “existence” of the hidden bonus feature 200 is generally made known on the face of the casino game such as: “This Game has a Hidden Bonus That Pays $20,” “This Game Has Mystery Bonus—Can you Figure It Out?” In the case of the slap jack hidden bonus feature 200 example above, the “existence” may be made known: “Slap Jack Hidden Bonus,” but with no instructions on what, exactly, initiates the hidden bonus feature and what to do or how to respond. In the case of the four watermelons (and, for example, touching the fourth watermelon), the existence may be known such as “Watermelon Hidden Feature” but with no information given anywhere on the gaming machine 10 for the player to know when it has occurred and then what to do to input 370 for a correct response 310.
What is important is that while the “existence” of a hidden bonus feature 200 (somewhere within the casino game) may be alluded to or otherwise generally made known, the occurrence of the hidden bonus feature 200 during the casino game is not overtly displayed to the player. In this fashion, unknowledgeable players are not frustrated at knowing they're supposed to do something and failing. Knowledgeable players are still rewarded.
The hidden bonus feature 200 of the present invention is a special attraction to the players in that it occurs, perhaps suddenly as a graphic (or the combination of game symbols 92 suddenly appears) on the display 110 to the player. As such, it may surprise the player. But, there are no instructions on the casino game as to what the player should do when the hidden bonus feature 200 appears. It may well be that others watching the player may educate the player as to what to do (i.e., touch the parrot or “You have four watermelons, hurry and touch the last watermelon!”). This all adds to the surprise, excitement, and perhaps mysteriousness surrounding the hidden bonus feature 200 of the present invention.
In
As another preferred example, the graphic displayed is a variation of one the player has come to expect. As an example, the parrot 400 may be used as the “emcee” in a knowledge-based bonus game on an underlying slot machine. As the trivia question and answers are shown to the player in the bonus game, he may cheer on the player with phrases such as “Let's get this one?” “This one's a gimme!” “I love you!” and so forth. As a hidden bonus feature 200, he may, instead of one of the standard phrases, randomly flip a gold coin and ask, “Who wants some credits?” To the initiated observer, this is a subtle cue. To the uninitiated observer, this particular phrase, and its timing, looks much like any of the many other phrases and actions the parrot 400 may do. However, when the player touches 370 the parrot 400 on the display 110 within three seconds, a random award 330 is given to the player. If the player does nothing, or first touches 370 a response to the trivia answer, then no hidden award 330 is given and path 312 is entered for continuation of the casino game. The use of a cue adds excitement to the casino game since while the player is uninitiated, an observer may yell out what to do upon seeing the cue.
In another embodiment of the present invention, the correct action 370 to take during the occurrence of a hidden bonus feature 200 is touching (via touch screen) the object in question. This is a simple but effective means for the player to respond to the machine in a fashion that acknowledges that the hidden bonus feature 200 has been discovered. It is an advantage of this approach that the player need not memorize complicated sequences of button pushes and so forth, which more resemble an exam than a game of entertainment. It is an advantage of this approach that the player who discovers the feature then has no further memorization to do.
Under another embodiment of the present invention, the hidden bonus feature 200 can be any type of cue to the player. The hidden bonus feature 200 can be an animated sequence, a video sequence, a graphic, a letter or number, a casino logo, a sound, etc. The present invention is not limited to the form, shape or type of hidden bonus feature 200 used. Furthermore, when the hidden bonus feature 200 is not to be displayed, an alternate feature can be displayed. For example, the parrot 400 can be displayed in an animated sequence simply flapping its wings without showing the gold coin 410.
In one embodiment of the present invention, some mode of timing is utilized in conjunction with the hidden bonus feature 200. A clock, internal timer, etc., such as for three seconds can be used. Alternatively, the player may have no time limit per se in step 310, except that if the hidden bonus feature 200 is not responded to as the first response, then it goes away. As an example of this alternative, consider a trivia-based bonus game with a hidden bonus feature 200. The hidden bonus feature 200 may be on-screen motion (e.g., a bird 400 flipping a gold coin 410), or perhaps a change in artwork that the player sees (e.g., an orange sun instead of a yellow sun). Provided the player responds 312 correctly, by first touching 370 the element that comprises the hidden bonus feature 200, before selecting an answer to the trivia-based bonus game, the hidden bonus feature 200 is awarded 330. On the other hand, if the player selects and answers the trivia question, the hidden bonus feature 200 is not awarded.
The hidden bonus feature 200 of the present invention may, as discussed earlier, interrupt the play of the casino game, be part of the play of the casino game, or occur in parallel with the play of the casino game as discussed above with the parrot graphic 400. The present invention uses a hidden bonus feature 200 occurring in a display 70, 110 of the casino game to the player. In one embodiment, the hidden bonus feature 200 is not disclosed to the player in the instructions for or on the casino game. Alternatively, the casino game may be denoted as having a hidden bonus feature 200 existing, but with no other information about the hidden bonus feature 200 disclosed to the player such as what it is, when it occurs, why it occurs, or how to respond. The hidden bonus feature 200 of the present invention is a bonus in that it delivers an award 330 in addition to what is normally expected by the player during play of the casino game.
