A portion of the disclosure of this patent document contains or may contain material which is subject to copyright protection. The copyright owner has no objection to the photocopy reproduction by anyone of the patent document or the patent disclosure in exactly the form it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.
The present invention relates in general to a gaming device, and more particularly to a gaming device having player selectable awards and award modification options.
Gaming devices currently exist with bonus rounds in which a player has one or more opportunities to choose masked bonus values from a pattern of masked values displayed to the player. When the player chooses a masked value from the pattern, the game removes the mask and either provides the player with a bonus value or terminates the bonus round with a bonus terminator. The outcome depends upon whether the player selects a value or a terminator.
In the above game, the controller of the gaming device randomly places a predetermined number of masked values and terminators in the pattern at the beginning of the bonus round and maintains the positioning until the bonus round terminates. When the player selects a masked value, the player receives the value, and the game typically displays a message that the player may continue and enables the player to select another masked award. The player then selects another masked value, and the process continues until the player selects a masked terminator. U.S. Pat. No. 6,190,255 B1, which issued on Feb. 20, 2001, and which is assigned on its face to WMS Gaming Inc., discloses a bonus game of this type.
Gaming machines also currently exist with bonus rounds in which the game selects or determines the player's award. PCT application PCT/AU97/00121 entitled, Slot Machine Game with Roaming Wild Card, having a publication date of Sep. 4, 1997, discloses an example. In this game, 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 symbol. The bonus symbol moves from game symbol to game symbol temporarily changing the game symbol to a bonus symbol. If the change results in a winning combination, the player receives an award.
In the first known game, the “go-until” or “do-until” bonus can end quite quickly if the player selects a bonus terminator early in the bonus round. The player selects masked symbols until selecting the bonus terminator, which is immediately displayed. The player's involvement in the bonus round is thus limited. The player has no opportunity to undo or redo an undesired pick. The player has no opportunity to optimize or maximize the bonus round award. In the second known game, the game completely determines the bonus round award, and the player has no effect on the outcome.
Gaming devices provide enjoyment and excitement to the player, in part, because they may ultimately lead to a monetary award for the player. Gaming devices also provide enjoyment and excitement to the player because they are fun to play. Bonus games, in particular, provide gaming device manufacturers with the opportunity to add enjoyment and excitement to that which is already expected from a base game of the gaming device. Bonus games provide extra awards to the player and enable the player to play a game that is different than the base game.
A continuing need exists for gaming devices that provide awards in an exciting and enjoyable manner. In this respect, it is desirable to enable the player to have an impact on, or a hand in, determining the player's award. It is also desirable to enable a player to optimize an award. It is further desirable to increase the level of player interaction. Each of these features is desirable in a base or primary game and in a bonus or secondary game.
The present invention provides a gaming device that has a player selectable award feature that may be implemented with a primary or bonus game. More specifically, the present invention provides a processor controlled gaming device that randomly generates a plurality of positions or digits of an award and enables the player to pick which position or digit receives a first randomly generated number, which digit receives a second randomly generated number, etc., until each of the positions have a number, whereby the gaming device determines the player's ultimate award based on the order of the number in the positions. This sequence or feature may be employed in a bonus game, in a known base or primary game or in any stand alone game.
In one embodiment, the gaming device randomly generates a number and does not disclose or reveal the number to the player. The game prompts the player to pick one of the award positions or digits. When the player selects one of the award positions or digits, the game reveals the number in the selected position or digit. The player hopes that higher numbers will be generated in positions or digits having a relatively high order of magnitude, e.g., the hundred's digit for a three digit award.
In another embodiment, the gaming device randomly generates and displays a plurality of player selectable masked numbers or selections and enables the player to place the selections or masked numbers in an order (i.e., in the positions or digits of an award). During or after the player directs the placement of the selections or masked numbers, the game reveals the numbers and the player's award.
The gaming device may be adapted to provide an equal amount of selections and digits, more selections than digits or less selections than digits. The present invention provides several different visual techniques for enabling the player to place masked numbers into the award positions or digits. In certain embodiments, the gaming device enables the player to change the order of masked numbers before revealing the player's award. When the player is certain of the desired masked number arrangement, the game reveals the numbers.
In a preferred embodiment, the player's award is the displayed value, which is the combination of the revealed numbers in the selected digits. In other embodiments, the game can multiply one or more of the digits, add one or more of the digits and/or use the face value of other digits to form some or all of the player's award.
In one bonus game embodiment, the game initially randomly generates and displays a number of inputs and prompts the player to select one of the inputs. When the player selects an input, the game generates and displays a number of masked numbers. In one embodiment, the game also displays how many numbers are to be displayed, e.g., the number “three,” before displaying three masked numbers.
When this sequence is combined with the base game of slot, the initial random generation of the number of masked numbers may be replaced by the intermittent random generation of the masked numbers or selections on the reels of the slot machine. The slot game provides a secondary or jackpot award having a number of positions or digits (preferably three). As one or more players play the base slot game, they generate a required set of masked numbers and fill in the positions or digits of the jackpot award in a desired order. The game eventually reveals the masked numbers and awards the jackpot award to the player who completes the required set. It should be appreciated that the jackpot award may be progressive, e.g., incrementally built using a percentage of the player's wager.
The present invention further provides for modification of the player's award. The modification may be randomly triggered, provided as an option to the player or automatically executed based on the expected value of the current award. When randomly triggered, the gaming device in one embodiment provides a modifier upon a player's selection of a masked number or upon the players selection of an award position or digit. That is, when the player selects an award position or digit or selects one of the selections or masked numbers, the gaming device, instead of providing or revealing a number, provides or reveals a modifier. Alternatively, the game may be adapted to randomly generate an award modifier based on some other triggering mechanism, such as the generation of a particular number or set of numbers.
When provided as an option, the player decides whether to keep the currently generated award or risk the award and let the award modification take place. In one embodiment, the gaming device automatically provides the award modification option to the player. In another alternative embodiment, the gaming device randomly determines whether or not to provide an award modification option based on the player's selection or upon another triggering event.
Several different modification sequences or methods are provided by the present invention. In one preferred embodiment, the gaming device randomly generates one of the modification methods when the player decides to modify rather than keep a generated award. The modification methods include, among others: scrambling or rearranging the digits of an original award, completely regenerating the award, adding a digit to the award, subtracting a digit from the award and multiplying the award.
In the scramble or rearrangement modification method, the processor rearranges the digits of a currently generated award. In the option embodiment, once the player chooses to modify the current award, and the game randomly generates the rearrangement option, the player is provided the rearranged award regardless of whether the award is higher or lower. In another embodiment, the game determines the expected value for the originally generated set of digits and automatically rearranges the player's award if the expected value exceeds the current award.
In the award regeneration modification method, the gaming device enables the player to replay the game and generate a new award. In the option embodiment, once the player chooses to modify the current award, and the game randomly generates the regeneration option, the player is provided the regenerated award regardless of whether the award is higher or lower.
The add a digit modification method in one embodiment adds a one's digit of five to the end of the player's current award and slides each existing digit up an order of magnitude, thus, the award 416 becomes 4165. The subtract a digit modification method in one embodiment removes the lowest number or value from the player's current award. For example, the award 416 becomes 46. The multiply modification method in one embodiment randomly selects a multiplier and multiplies the player's current award, e.g., a multiplier of three times 416.
It is therefore an advantage of the present invention to provide a gaming device that enables a player to have a direct impact on determining an award.
Another advantage of the present invention is to provide a gaming device that selectively enables the player to keep or modify an award.
A further advantage of the present invention is to randomly employ one of a number of award modification methods to provide a varied and exciting gaming device.
Yet another advantage of the present invention is to provide a gaming device that increases the level of player interaction.
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 an embodiment, at the same time that the “X,” “Y” and “Z” selections 116 are displayed, the game also displays a number of positions 118, 120 and 122, which correspond to digits of the player's award. The positions 118, 120 and 122 do not initially contain or display numbers. In one preferred embodiment, the game displays the same number of positions or digits, such as positions or digits 118, 120 and 122, as there are masked numbers 116. That is, the game displays the same number of masked numbers 116 as the positions or digits. In this embodiment, the number of selections 116 sets the order of magnitude of the player's award. For reasons which become apparent below, the game of the present invention preferably displays an award having at least two positions or digits.
In another embodiment, the game displays more masked numbers 116 than positions or digits. That is, the player will not be able to select or use each displayed selection 116. This alternative embodiment may be implemented in a number of ways. In one implementation, the game generates a number of positions or digits, such as the positions 118, 120 and 122, which is equal to or less than the number of masked numbers 116. That is, if the game displays four selections 116, the game generates and displays two, three or four positions (preferably at least two). In this implementation, the game may be adapted to weight the selection, e.g., provide a 60% chance of selecting three numbers, provide a 20% chance of selecting two numbers and provide a 20% chance of selecting four numbers.
In another implementation, the game always displays the same number of positions or digits, e.g., the three positions 118, 120 and 122. The game then generates at least that number of masked numbers 116. This implementation sets the number of digits or the order of magnitude of the player's award, even though the first and second digits may turn out to be zero.
In a further implementation, the game displays less selections 116 than positions or digits. In this embodiment, the game may randomly generate the number of positions or digits or maintain a preset number as described above. This implementation may require the player to use or select a masked number 116 more than once. For instance, the game displays the “X” and “Y” numbers 116 and the positions 118, 120 and 122, wherein the player must use either the “X” or the “Y” twice. This implementation may also be adapted so that the game supplies one of the numbers. For instance, the game displays the “X” and “Y” numbers 116 and the positions 118, 120 and 122, wherein the one's digit 122 automatically has a value of zero. In this implementation, the player only determines the hundred's and the ten's digits.
In
The game thereafter provides a visual, audio or audiovisual message 136 informing the player to select one of the numbers 116 for the one's digit or position 122. As illustrated in
In one preferred embodiment, the game does not enable the player to reselect a previously selected masked number 116. For instance, when the player 114 picks the “Y” number 116 for the hundred's position 118, the game removes, grays out, darkens or otherwise indicates that the “Y” number 116 is no longer selectable. In this embodiment, the game may be adapted to fill in the last digit, e.g., the position 122, after the player makes the second to last pick, since there is only one other choice. In another embodiment, the player is able to pick the same masked number 116 a predefined number of times or any amount of times, so that the selected masked award can thus be “Z,” “Z,” “Z,” if desired.
Upon providing the message 132, 134 or 136, the game highlights, flashes or otherwise indicates the hundred's 118, ten's 120 and one's 122 positions, respectively, and/or grays out or otherwise indicates that the other positions are not to be currently filled. The present invention includes a selection ordering device that enables the player to order the selections. The selection orderer may be adapted a plurality of ways. In one embodiment, the selection orderer is adapted so that the selections 116 are selectable areas of a touch screen 50 that are each individually adapted to send a discrete input to the processor 38. When the game highlights the hundred's position 118 and the player selects the “Y” number 116, the game places the “Y” in the hundred's digit. The game alternatively uses separate electromechanical devices (not illustrated) representing each of the numbers 116 in a like manner as the touch screen 50 areas.
In another embodiment, the selection orderer is adapted so that the touch screen 50 enables the player to press and drag or place a number 116 on a position or digit. The selection orderer in one implementation visually displays the number 116 moving to the desired digit, so that the player can discern when it is in position. In another implementation, the selection orderer maintains an area in the memory device 40 that acts similar to the Microsoft™ clipboard, whereby the game remembers the last number 116 that the player selected. For instance, if the player selects the “X” number 116, the game stores the “X” on the clipboard. When the player touches the one's digit 122, the game remembers that the “X” is on the clipboard and places the “X” in the one's position 122. If the player selects two numbers 116 sequentially, the game may be adapted to either write over or maintain the original selection.
The select and drag or select and place embodiments of the selection orderer are not time dependent and may be advantageous in that they let the player fill in the award digits as desired by the player. These selection orderers may further be adapted to allow players to change their minds and move the selections 116 after they have been placed in a position or digit. If the player moves a number 116 to an empty position or digit, the game needs to take no further action and awaits the player's next selection. If the player moves a selection 116 to an occupied position or digit, however, the game preferably writes over the previous selection, redisplays the removed selection 116 on the display device 30 or 32, ungrays it or otherwise indicates that it is once again selectable. The game may be adapted to allow the player to change masked numbers a limited or unlimited number of times. This embodiment preferably includes a “keep it” or select button (not illustrated), which enables the player to send a signal to the processor to indicate that the current positioning or ordering is satisfactory and to reveal the award as selected.

Gaming device 10 may be adapted to randomly assign numbers to each of the player's picks before the player actually makes a selection, or the game can make the random assignments as the player makes the selections. Preferably, however, even a contemporaneous assignment gives effect to the player's decision. Giving effect to the player's selection order is further discussed below in connection with
In an alternative embodiment, the gaming device may assign the numbers based on the position that the player selects. In such a case, gaming device 10 assigns a number to the hundred's digit 118, the ten's digit 120 and the one's digit 122 before the player makes any selections. Here, the order that the player selects the digits does not affect the overall award, which is less desirable. Not giving effect to the player's selection order is further discussed below in connection with
In the screen 90 of
Referring now to
The game may reveal the masked numbers 116 all at once or one at a time. If revealed at different times, the game may reveal the masked numbers in the order that the player placed the numbers 116 in the positions (e.g., as the player places a number), from left to right, right to left, or in any other desired manner. If the game generates more masked numbers 116 than positions, the game may be adapted to reveal the unselected numbers 116 at this time or at any other time when the player can no longer select the number 116. Accordingly, the game may continue to display the masked numbers 116 or only the unselected masked numbers 116, if desired.
The game may be adapted to add other features to the reveal sequence to enhance the player's enjoyment and excitement. For example, the game in one embodiment shows all three revealed numbers to the player somewhere on the display device 30 or 32 before displaying which position the numbers belong to. The game in another embodiment audibly announces the generated numbers from the speakers 36 before revealing their positions. Informing the player of the chosen numbers but not their positions enhances the player's anticipation.
In one preferred embodiment, the award is formed by revealing values in the positions or digits 118 through 122, as illustrated. The award is the number created and displayed on the display device 30 or 32. In another embodiment, the game performs a mathematical operation using the generated values. For instance, the game in one implementation multiplies 4.times.1.times.6 and provides the player an award of 24. The game may be adapted to employ any combination of addition, multiplication, subtraction or division to form the player's award.
In a further embodiment, the award is formed through a combination of revealing values in the positions or digits and by performing a mathematical operation. For example, instead of displaying 416, the positions 118 through 122 display 4, 3.times. and 6, respectively. In this embodiment, the game takes the 4 and places it in the ten's digit to form an amount of 46. The game then multiplies the 46 amount by 3 to form the player's overall award. The game also preferably provides a suitable visual grouping display to show the player what is happening. The game could alternatively slide the 6 into the ten's digit, assume a value such as zero for the one's digit, form the amount of 460 and multiply the 460 amount by 3 to determine the player's award.

In another embodiment, the numbers or values are weighted, as illustrated by database 142. For each of the masked numbers “X,” “Y,” and “Z,” the game generates and assigns or associates one of the values 0 through 9 from the database 142. The database 142 may also include multipliers or other mathematical modifiers as described above.
In the database 142, it is more likely that the game generates and assigns the 0, 1, 2 or 3 value to the masked numbers 116 (
In another embodiment, the player's placement of the masked numbers 116 (
In
The weighting distribution is different for the tens digit 120, as illustrated by the database 146. Here, the middle values 4 through 6 are generated slightly more often than the lower or higher values. The higher values of 7, 8 and 9 each have a ten percent chance of being generated, while the lower values each have a less than ten percent likelihood of being generated. For the one's digit 122, the database 148 weights the values 0 through 9 such that the highest values are most likely to be generated, the middle values the second most and lowest values the least most likely to be generated.
In the illustrated embodiment, it is thus more likely to receive a lower value in the hundred's position 118, a middle value, on average, in the ten's position 120 and a higher average value in the one's position 122. Different distributions can obviously be achieved in accordance with a desired payout percentage by varying the weightings of the individual databases. Each of the databases 142 through 148 is programmed and stored in the memory device 40 as is well known. One or more random number generators, which are also preferably stored as software code, generate numbers according to the desired weighting system.
In one embodiment, the game provides a predefined number of masked numbers 116 (
The screen 145 can present any number of selectable inputs, such as inputs 102 through 108, and is not limited to presenting four as illustrated. The selectable inputs in one embodiment are areas of a touch screen 50 (see
The inputs 102 through 108 are each associated with a quantity of the masked numbers 116 or digits, such as digits 118, 120 and 122, which are stored in an area of the memory device 40. The area of the memory device 40 having the quantity of masked numbers 116 or digits is illustrated here in phantom for purposes of describing the present invention. In the game, the player does not know the quantity of masked numbers 116 or digits associated with any of the selectable inputs.
To simplify the illustration, the screen 145 illustrates one embodiment, wherein the game randomly assigns a quantity of masked numbers 116 to each selectable input 102 through 108. It should be appreciated, however, that gaming device 10 may alternatively be adapted to assign a quantity of digits, such as the digits 118 through 122, to the inputs 102 through 108. Each selectable input is randomly assigned a quantity of masked numbers 116 from a database or table (not illustrated), which is stored in the memory device 40. The database may be weighted such that a particular quantity or set of quantities is assigned more often than another quantity or set of quantities. This embodiment enables the game to reveal the quantities of the masked numbers 116 for the unselected inputs after the player chooses one of the selectable inputs 102 through 108.
In another embodiment (not illustrated), the game does not assign a different quantity of masked numbers 116 to each input 102 through 108; rather, the game randomly assigns a quantity to a particular game. That is, the game generates and displays the same quantity of masked numbers 116 no matter which input the player selects. In this embodiment, the game also picks from a database stored in the memory device 40 that may be weighted such that a particular quantity or set of quantities is assigned more often than another quantity or set of quantities.
In one embodiment, the database is weighted so that it is more likely that the player generates a particular number of, such as three, masked numbers 116. The screen 145 illustrates that if the player selects either the “B” input 104 or the “D” input 108, the game displays three masked numbers 116 on the display device 30 or 32. If the player selects the “A” input 102, the game only displays two masked numbers 116, and if the player selects the “C” input 106, the game displays four masked numbers 116. For the reasons discussed below, the game preferably provides at least two masked numbers 116. As illustrated in this schematic example, when the player 114 picks the “B” input 104, the game generates three masked numbers 116.
The game as illustrated in
The joeys can represent either masked numbers 116 or digits, e.g., digits 118 thorough 122. In one implementation, the game is predefined to provide three joeys and three digits or positions. Another implementation employs the selectable inputs 102 through 108, which are each mother kangaroos. Here, the player selects one of the mother kangaroos and a quantity associated with the selected input appears, e.g., the number “three,” whereby this quantity of joeys are shown to come out of the selected mother kangaroo.
In one implementation (

The select lines input 152 enables the player to pick whether to play one, two or three paylines 56. The slot machine of the present invention may be adapted to have any number of paylines 56 and typically has one, three, five, nine, fifteen or twenty-five paylines 56. The bet per line input 154 enables the player to wager a desired amount of coins or tokens on the desired number of paylines. The slot machine of the present invention may be adapted to allow the player to wager any amount of coins or tokens per payline and in one preferred embodiment allows the player to wager up to five coins per payline. The max bet input 156 is a convenience input that enables the player to play the maximum amount of coins or tokens on all available paylines upon a single input by the player.
The screen 150 also includes the positions or digits 118 through 122 having the functions as described above in connection with
In connection with the slot game, the present invention operates substantially as described above. The main difference is in how the game generates the masked numbers 116. Instead of generating the masked numbers 116 all at once, the slot base game generates the masked numbers 116 intermittently according to the number of masked numbers 116 that the implementors place on the reels 34, the rules of the game, the player's wager and luck.
The implementors dispose masked numbers 116 on the reels 34 to achieve the desired payout percentage of the game. One, a plurality of or all the reels may include masked numbers 116. Each of the reels having masked numbers 116 may be adapted to have one or a plurality of the masked numbers 116. The game may be adapted to require the player to generate a masked number for use with the jackpot award: (i) on an active payline; (ii) on an active payline having max coins wagered; (iii) when all paylines are active; or (iv) when the player plays max coins. The game may alternatively provide a masked number 116 anytime the game generates one anywhere on the reels 34.
The player selectable award of the present invention can be combined with the base game of slot in many different ways. As indicated by the visual, audio or audiovisual message 158, in one implementation the player must place an “X,” “Y” and “Z” masked number 116 in the positions 118, 120 and 122, as before, to win the jackpot award. If the player generates the “X” a number of times in a row, the subsequent generations after the first generation do not help the player win the jackpot. In this implementation, the game may be adapted to associate a value database with the masked numbers 116 or the positions 118 through 122, as described in connection with
In another implementation, the reels 34 contain masked numbers 116 having the same indicia. That is, instead of “X,” “Y” and “Z,” the numbers 116 have only “X” or some other desired indicia. The player places the masked numbers 116 in the positions or digits as before. Here, the game preferably assigns a value and thus a value database to the position or digit 118, 120 or 122 with which the player places the number 116.
In a further alternative embodiment, which coincides with the disclosure in connection with
In any implementation, the game may reveal the masked numbers 116 or digit selections as the player places them or alternatively after each position has been selected or has a masked number. If revealed all at once, the game may be further adapted to allow the player a chance to rearrange the selection a limited or unlimited number of times before revealing the award. In this rearrangement, the game would flip flop a non-revealed number placed on one position with a non-revealed number placed on another position. The game would provide a “keep it” or select button (not illustrated), which would enable the player to send a signal to the processor 38 that the current positioning is satisfactory and to reveal the award as selected.
The award in the slot machine embodiment is a secondary or jackpot award. The slot machine game generates other base game awards according to a paytable of winning combinations of the symbols presented by the reels 34. The player selectable award of the present invention, which is in the nature of a bonus or extra award, is likely to be a relatively large award in relation to the base game awards to attract players and to increase the fun and excitement associated with the gaming device 10. Large, one time or intermittent awards of this type are often termed jackpot awards.
The player selectable award as described in connection with the base game of slot is a persistent award, that is, it takes a series of games or a period of time before a player wins the award. That is, the positions or digits 118 through 122 preferably do not zero out when a player cashes out by selecting the cash out button 26. If a first player generates the “Z” and the “X” and leaves the gaming device 10 before generating the “Y” and the jackpot award, a second player stands in the first player's place (only needs the “Y”) upon beginning play. The award may also be progressive and be funded by a percentage, e.g., ten percent, of each wager.
It should be appreciated that the base games of blackjack, poker and keno may be modified to include the player selectable award feature of the present invention. In either of the card base games of poker and blackjack, designated face cards or cards having other indicia interspersed among the face cards are used as the masked symbols 116. In the base game of keno, designated numbers or other indicia interspersed among the keno numbers are used as the masked symbols 116.
The game of the present invention, in any of the embodiments previously described, includes modifying the player's award. In one embodiment, the gaming device randomly determines when to modify the player's award. In another embodiment, the gaming device modifies the player's current award when the current award is less than the expected value.
In another embodiment, gaming device 10 provides the award modification as an option. That is, after placing masked numbers 116 in the positions or digits 118 through 122 (

If the player elects to keep the original award by selecting the keep input 166, the game provides it to the player and game play resumes. If the player elects to modify the award by selecting the modify input 164, the game in one embodiment randomly generates one of a number of different modification methods. The random selection of a modification method also applies to embodiments wherein modification is not an option and instead occurs randomly or based on an expected value.
Since the different methods have substantially different potential outcomes, the generation of the method is preferably weighted, although it does not have to be. Generally, the more drastically the original award may change due to a modification method, the less likely it is that the game generates that modification method.
The modification methods includes the following: (i) an award rearrangement or scramble using existing numbers or digits; (ii) a complete regeneration; (iii) an addition of a digit to the original award; (iv) a removal of a digit from the original award; and (v) a multiplication of the original award. Each of these modification methods is discussed in turn below. Alternative implementations of the award modification embodiment include any combination of less than all of the modification methods.
In the kangaroo/joey theme described above, in one implementation, three joeys or masked numbers 116 appear from the mother kangaroo. The player orders the joeys, and the game reveals an award and an award modification option. In one implementation, the game provides an area of the touch screen 50 which is associated with a displayed help button. When the player presses the help button (not illustrated), the display 30 or 32 provides a help screen (not illustrated) that explains each of the modification methods, i.e., the potential awards and losses associated with each method. If the player chooses to modify the award, another joey or theme related symbol appears from the mother kangaroo and reveals which modification option the player has drawn.

The game provides the scramble modification method to the player according to a predefined or varying probability stored in the memory device 40. Since the scramble modification method maintains the order of magnitude of the player's award (i.e., such as a three digit award) and may result in a higher or lower award (i.e. which results from the change in the order of the numbers in the award positions), this method is generated relatively often. The game can alternatively predefine this option to result from the occurrence of some game event, such as a particular combination of slot symbols, face cards or other event.
The scramble modification option enables the player to flip-flop or scramble the digits, i.e., change the order of the digits in the award. The scramble works in one of two primary ways. Assuming the award has three digits (even if the first and second digits are zero), the game either randomly selects from all six combinations of three digits, including the player's current award, or, from the five remaining combinations besides the current award. That is, if the player decides to risk the award, the game generates a different award, for better or worse. In the above example, the player risking an award of 416 might obtain an award of 146, 164, 461, 614 or 641. In the other implementation, the player might also receive 416 again. In either case, the game in one implementation evenly weights each possibility.
In the screen 170 of
As described above, the player selectable award is preferably at least two and most preferably at least three digits. It should be appreciated that the award rearrangement option is inapplicable to an award of a single digit. The award rearrangement option is too simple for an award having two digits. Players would generally choose to rearrange an award of 19 to try to obtain an award of 91 and at the worst wind up with an award of 19 unless a related consolation award was less than the award of 19. Four digits provides a significant number of combinations for the player to understand and also requires a relatively substantial award. Therefore, the rearrangement option is preferably applied to a three digit award.
In an alternative embodiment, the game does not provide an option and instead automatically scrambles or rearranges the award when the expected value of the digits of the current award exceed the current award, i.e., when the smart play is to exercise the rearrangement option. Using the implementation wherein the game selects only from the different permutations of the player's award, in the example where the game generates an award of 416, the expected value after rearranging the award is (146+164+461+614+641)/5=405.2. Thus, even though three out of five results increase the current award of 416, the smart play is to keep the 416 award. The game in the auto-rearrange embodiment therefore does not rearrange the player's award. In this situation, the game may be adapted inform the player that the smart play is to keep the current award, but that the player may rearrange at the risk of obtaining a lower award.
In another alternative embodiment, gaming device 10 automatically and randomly rearranges the player's award. Gaming device 10, for example, may be adapted to rearrange the player's award on average once every ten games, wherein a random generation software generates a rearrangement using the weighted distribution.

The game provides the regeneration method to the player according to a predefined or varying probability stored in the memory device 40. Since the regeneration method maintains the order of magnitude of the player's award and may result in a higher or lower award, this method is generated relatively often. The game can alternatively predefine this option to result from the occurrence of some game event, such as a particular combination of slot symbols, face cards or other event.
The regeneration option enables the player to obtain a completely new set of digits, i.e., the new award is not constrained to have the same numbers as the old award. The regeneration in one embodiment includes randomly picking a number from zero to nine for each of the positions 118, 120 and 122, wherein each number has an equal chance of generation. This option can be favorable for the player who has an original award with low numbered digits or a detriment to the player with a high original award.

In another alternative embodiment, gaming device 10 automatically and randomly regenerates the player's award. Gaming device 10, for example, may be adapted to randomly regenerate the player's award on average once every ten games. Further alternatively, gaming device 10 may be adapted to regenerate the player's award whenever the award falls below a predefined threshold.

The game provides the add digit method to the player according to a predefined or varying probability stored in the memory device 40. Since the add digit method changes the order of magnitude of the player's award (i.e., the number of digits in the award) and can only increase the original award, this method is infrequently generated. The game can alternatively predefine this option to result from the occurrence of some game event, such as a particular combination of slot symbols, face cards or other event.
The add digit method enables the player to obtain an extra digit, i.e., the new award has the same numbers in the same order as the old award, plus the new award has an extra digit. The add digit method in one embodiment includes randomly picking either the number zero or five and appending it to the right end or one's digit of the original award. The add digit method may be adapted to generate and add any number, zero to nine, in any one of the one's, ten's, hundred's or thousand's digits. The additional number generated obviously has less significance as it is placed in lower digits. It can be seen that this option is highly desirable for the player regardless of the size of the original award.
In another alternative embodiment, gaming device 10 automatically and randomly (as opposed to an option) adds a digit to the player's award. Gaming device 10, for example, may be adapted to add a digit upon the player's placement of a masked number 116 (

The game provides the subtract digit method to the player according to a predefined or varying probability stored in the memory device 40. Since the subtract digit method changes the order of magnitude of the player's award (i.e., the number of digits in the award) and can only decrease the original award, this method is infrequently generated. The game can alternatively predefine this option to result from the occurrence of some game event, such as a particular combination of slot symbols, face cards or other event.
The subtract digit method removes a digit from the player's original award, e.g., the new award has two out of the three original numbers in the same order as the old award. The subtract digit method in one embodiment includes eliminating the lowest number from the original award. The subtract digit method may however be adapted to randomly eliminate any number from the original award. The actual number eliminated has less significance than the fact that the player's award is losing an order of magnitude. It can be seen that this option is highly undesirable for the player.

In another alternative embodiment, gaming device 10 automatically and randomly (as opposed to an option) subtracts a digit from the player's award. Gaming device 10, for example, may be adapted to subtract a digit upon the player's placement of a masked number 116 (

The game provides the multiply method to the player according to a predefined or varying probability stored in the memory device 40. Since the multiply method may change the order of magnitude of the player's award and can only increase the original award, this method is intermediately generated. The game can alternatively predefine this option to result from the occurrence of some game event, such as a particular combination of slot symbols, face cards or other event.
The multiply method generates a multiplier and multiplies this number by the player's original award to form a new award. The multiply method in one embodiment includes randomly generating either a 2.times. or a 3.times. multiplier. The multiply method may however be adapted to randomly generate any multiplier from a weighted or non-weighted table of multipliers. It can be seen that this option is desirable for the player.

In another alternative embodiment, gaming device 10 automatically and randomly (as opposed to an option) multiplies the player's award. Gaming device 10, for example, may be adapted to multiply the player's award upon the placement of a masked number 116 (
