A controller is configured to set a volatility factor to a first volatility value, set a number of plays to a first random number of games, and establish a counter of a number of games played. The controller is also configured to display a first instance of the game on a display device, randomly select an outcome of the first instance of the game, display the outcome on the display device, and award an award to the player as a function of the outcome of the first instance of the game and the volatility factor if the outcome of the first instance of the game is a winning outcome. The controller counts the number of games played and, if a predetermined number of games have been played, sets the volatility factor to another volatility value.
Description
- The present invention relates generally to video gaming machines and more particularly, to an apparatus and method for providing a video game with varying volatility.
- Gaming machines, such as slot machines, are a cornerstone of the gaming industry. Generally, the popularity of such machines with players is dependent on the perceived likelihood of winning money at the particular game and the intrinsic entertainment value of the game relative to other available gaming options. Where the available gaming options include a number of competing games and the expectation of winning each game is believed to be generally the same, players are most likely to be attracted to the most entertaining and exciting games. Thus, gaming operators strive to employ the most entertaining and exciting games available because such games attract frequent play and, hence, increase profitability to the operator.
- Furthermore, one concept that has been successfully employed to enhance the entertainment value of the game is the addition of a bonus game that may be played in conjunction with the “primary” game. The bonus game may comprise any type of game, either similar to or completely different from the primary game. The bonus game is initiated upon the occurrence of a selected event or outcome of the primary game.
- Because the excitement and entertainment value of the primary game provides increased player appeal relative to other gaming machines and the bonus game concept increases player appeal and excitement, thereby increasing the chance to win the potential pay-out amount, there is a continuing need to develop new features for primary and bonus games. New features are necessary to appeal to player interest and enhance excitement in order to entice longer play and satisfy demands of operators for interesting games and increased profitability.
- The present invention is directed to satisfying these needs.
- In a first aspect of the present invention, a method provides a game to a player. The method includes the steps of (a) providing a gaming machine having a display and a user interface, (b) setting a volatility factor to a first volatility value, (c) setting a number of plays to a first random number of games, and (d) establishing a counter of a number of games played. The method further includes the steps of (e) allowing the player to make a wager using the user interface, (f) displaying the game on a display device, (g) randomly selecting an outcome of the game and displaying the outcome on the display device, and (h) awarding an award to the player as a function of the outcome of the game and the volatility factor. The method also includes the steps of (i) incrementing the counter, (j) comparing the counter to the number of games played and, if the counter is equal to the number of games played: (1) resetting the counter, (2) setting the volatility factor to another volatility value, and (3) setting the number of plays to another random number of games played. Steps (e)-(j) are then repeated.
- In a second aspect of the present invention, a method provides primary and secondary games to a player. The method includes the steps of (1) providing a gaming machine including a display and a user interface, (2) setting a volatility factor to a first volatility value, (3) setting a number of plays of the primary game to a first random number of games, and (4) establishing a counter of a number of games played of the primary game. The method further includes the steps of (5) allowing the player to make a wager on the primary game using the user interface, (6) randomly selecting an outcome of the primary game, (7) displaying the primary game on the display, (8) determining if the outcome of the primary game is a winning outcome, and (9) awarding the player a primary award as a function of the outcome, the wager made by the player, and a predetermined paytable. The method also includes the step of (10) determining if a triggering condition occurred in the primary game and initiating a secondary game, and for the secondary game: (a) randomly selecting an outcome of the game and displaying the outcome on the display device, (b) awarding an award to the player as a function of the outcome of the game and the volatility factor, (c) incrementing the counter and (d) comparing the counter to the number of games played and, if the counter is equal to the number of games played: (i) resetting the counter, setting the volatility factor to another volatility value, and setting the number of plays to another random number of games. Steps (5)-(10) are then repeated.
- In a third aspect of the present invention, a gaming machine provides electronic games to a player. The gaming machine includes a display, a user interface, and a controller. The controller is coupled to the display and the user interface. The controller is configured to set a volatility factor to a first volatility value, to set a number of plays to a first random number of games, and to establish a counter of a number of games played. The controller is also configured to allow the player to make a wager using the user interface, to display a first instance of the game on a display device, to randomly select an outcome of the first instance of the game, to display the outcome on the display device, and to award an award to the player as a function of the outcome of the first instance of the game and the volatility factor if the outcome of the first instance of the game is a winning outcome. The controller increments the counter, compares the counter to the number of games played and, if the counter is equal to the number of games played: resetting the counter, sets the volatility factor to another volatility value and the number of plays to another random number of games played. The controller is configured to allow the player to make a second wager using the user interface, to display a second instance of the game on the display device, to randomly select an outcome of the second instance of the game, to display the outcome of the second instance of the second game on the display device, and to award a second award to the player as a function of the outcome of the second instance of the game and the volatility factor if the outcome of the second instance of the game is a winning outcome.

FIG. 5 is a diagrammatic illustration of a third screen shot of the secondary game ofFIG. 3 ; and -
FIG. 6 is a diagrammatic illustration of a fourth screen shot of the secondary game ofFIG. 3 . - With reference to the drawings and in operation, the present invention provides a
gaming system 10 which provides a primary (or base) game or a primary and secondary games to players on one ormore gaming machines 14. - In one embodiment, the secondary game may be provided on a
single gaming machine 14. - In another embodiment, the secondary game may be provided on a plurality of linked
gaming machines 14. The secondary game may be a progressive game. Progressive games are well known in the art and are therefore not further discussed. - In one aspect of the present invention, the
system 10 and method randomly change or modify the volatility of the primary and/or secondary games. The term volatility may be used in reference to any factor or parameter of the primary and/or secondary games. - In one aspect of the present invention, there may be multiple levels of volatility. In one embodiment, the present invention changes between at least two levels of volatility. In another embodiment, the present invention changes between at least three levels of volatility, e.g., low, medium, and high volatility.
- In one aspect of the present invention, the volatility of a game is modified from a first state or value to a second random state of value. In one embodiment, the game maintains the current state of volatility for a random predetermined number of games (or cycles). The random predetermined number of games may have a minimum value, e.g., 10 or 50 games. In one embodiment, the volatility of a primary game (or game without a secondary game) is modified. In another embodiment the volatility of the secondary game is modified. In a third embodiment, the volatility of the primary and/or secondary game may be modified.
- The volatility of a game may be modified by changing one or more features or parameters of the game (for a random predetermined number of games or cycles). The features or parameters of the game which may be modified may include, but are not limited to game rules, paytables, symbol distribution, number of free spins awarded, e.g., in a video slot game, hit frequency, e.g., (high hit frequency with low payouts; medium hit frequency with medium payout; low hit frequency with high payouts), win evaluation, multipliers applied to payout of the primary and/or secondary games, and the trigger condition for the secondary game (if required), e.g., the number of symbols appearing in the primary game to trigger the secondary game.
- In one aspect of the present invention, the change in volatility does not affect the hold percentage of the
gaming machine 14. In another aspect of the present invention, the change in volatility changes the hold percentage of thegaming machine 14. - For example, in one embodiment the present invention may utilize or two or more paytables. Two exemplary paytables are shown below:
-
Paytable 1Paytable 2 Three As: 1,000 Three As: 3,000 Three Ks: 100 Three Ks: 180 Three Qs: 75 Three Qs: 120 Three Js: 50 Three Js: 60 Three 10s: 30 Three 10s: 50 Two 10s: 20 Two 10s: 10 One 10: 10 One 10: 6 - In a second embodiment, a preliminary (or base award) is determined as a function a predetermined paytable and based on the outcome of the game. The base award is multiplied by a randomly determined multiplier. The randomly determined multiplier is randomly selected from a set or table of multipliers. Each set or table of multipliers provides a different level of volatility. In this example, there are three tables, as indicated below:
-
TABLE A Multiplier Weight P(x) EV 5 50 0.14 0.71 4 50 0.14 0.57 3 100 0.29 0.86 2 150 0.43 0.86 350 3.00 -
TABLE B Multiplier Weight P(x) EV 10 55 0.16 1.57 3 50 0.14 0.43 2 100 0.29 0.57 1 150 0.43 0.43 355 3.00 -
TABLE C Multiplier Weight P(x) EV 25 29 0.08 2.07 3 25 0.07 0.21 2 50 0.14 0.29 1 150 0.43 0.43 254 3.00 - In this embodiment, upon machine reset or once the threshold number of games is hit, a new number of games is randomly determined. The number represents the number of games the
gaming machine 14 will stay in its current state before switching over to a new state. For example, if the number of games is determined as 130, the current game state will stay active for the next 130 games or cycles. - The states are defined by one of the Tables. In one embodiment, the new state (or Table) is randomly determined. In another embodiment, the states are cycled through, e.g., Table A, followed by Table B, followed by Table C, then back to Table A. Once the state, i.e., table is established, one of the multipliers in the table is randomly selected. The selected multiplier may be displayed. If there is a winning condition, then the award (normally) associated with the winning condition is multiplied by the selected multiplier and the product is awarded to the player. In this embodiment, the hold percentage across the three tables remains the same. The average value of the multiplier for all three states remains the same (3.0), but the states have increasing volatility from Table A to Table C.
- Table A includes multipliers of 5, 4, 3, and 2 with respective weights of 50, 50, 100, and 150. Thus, when Table A is active, there is a 50/(50+50+100+150)=14% of a multiplier of 5 being used. In contrast, Table B has a maximum multiplier of 10, while Table C has a maximum multiplier of 25.

The selected game elements are selected from a set of possible game elements. Thegame controller 40 is adapted to determine an outcome of each of the game based on the displayed game elements, the pay-table, a wager, and predetermined paylines. - Each video slot game is generally first played in a conventional manner. The player makes a wager, which may be based on a predetermined denomination and a selected number of paylines. The reels are spun and game symbols or elements are randomly chosen for each cell. If a predetermined pattern of elements are randomly chosen for each cell on a played payline, the player is awarded a payout based on the payline, the wager, and a predetermined paytable. Many variations to the above described general play of a video slot game fall within the scope of the present invention. Such video slot games are well-known in the art, and are therefore not further discussed.
- After the outcome of the
primary game 76 is determined, thesecondary game 70 may be played. In one embodiment, thesecondary game 70 is played automatically afterprimary game 76. In other words, after each play of theprimary game 76, one or more plays of thesecondary game 70 occur automatically. In another embodiment, the play of thesecondary game 70 is dependent upon the occurrence of a triggering condition. If the triggering condition is detected then thesecondary game 70 is initiated. - In one aspect of the present invention, the
secondary game 70 is a progressive game in which multiple players may be eligible in to win a, generally large, jackpot or payout. The jackpot or payout is generally funded from a pool which is added to through contributions from the wagers made by a plurality of players. The triggering condition for the progressive award may be the appearance of a triggering symbol within theprimary game 76 of one thegaming machines 14, or may be based on a separate random event. The triggering condition may be determined at the jackpot controller 12 or thegame controller 40. - Alternatively, the
secondary game 70 is a bonus game in which only the player who has triggered thesecondary game 70 may win and the secondary jackpot or bonus is funded from the associatedgaming machine 14. With respect to the bonus game, a plurality of thegaming machines 14 may be used to display the bonus game so that all of the players may share in the excitement of the bonus game. In one embodiment, the triggering condition is winning outcome condition. For example, inFIG. 3 , if theprimary game 76 has a winning condition, then the bonus award would be awarded in addition to the award for the winning condition of theprimary game 76. Alternatively, the triggering condition could be a losing outcome. - With specific reference to
FIGS. 2-3 , in one embodiment, thegaming system 10 includes a plurality of linkedgaming machines 14 and a jackpot controller 12. Eachgaming machine 14 includesdisplay game controller 40. Thecontroller 40 allows a player to make a wager on aprimary game 76, randomly selects an outcome of theprimary game 76 and determines if the outcome of theprimary game 76 is a winning outcome. If the outcome of theprimary game 76 is a winning outcome, thecontroller 40 awards the player a primary award as a function of the outcome, the wager made by the player, and a predetermined paytable. - The jackpot controller 12 determines if a triggering condition occurred in one of the
primary games 76 and initiates thesecondary game 70. The outcome of thesecondary game 70 is displayed using arotating selector device 72. - The jackpot controller 12 randomly selects an outcome of the
secondary game 70, spins rotatingselector device 72, and awards one or more of the players a secondary award as a function of the outcome of thesecondary game 70. - As discussed more fully below, in one embodiment the
secondary game 70 is a progressive game. The secondary award may be either a set amount or a progressive award or amount. In one embodiment the progressive award may be one of a plurality of progressive award levels. - Alternatively, the

gaming machine 14 includes adisplay user interface 13, and acontroller 40. The controller is coupled to thedisplay user interface 13. - The
controller 40 sets a volatility factor to a first volatility value. As discussed above, the volatility factor may be any parameter associated with the (primary or secondary)game controller 40 also sets a number of plays to a first random number of games. The number of plays of games defines how many plays of the game will be played using the current volatility value. A counter is used to count the number of games played. - The
controller 40 allows the player to place a wager using theuser interface 13. A first instance of the game is played and displayed on thedisplay controller 40 randomly selects an outcome of the first instance of the game, displays the outcome on thedisplay device - The counter is incremented and its value is compared against the number of games to be played and it the counter is equal to the number of games, the counter is reset and the volatility factor is set to another volatility value.
- The number of plays of the game is set to another random of games played and a next instance of the game is played.
- As discussed above, the volatility factor may be a paytable. For example the first volatility factor may be a first paytable and the second volatility factor may be a second paytable.
- In another embodiment, the volatility factor may be a multiplier which is applied to an award amount. For example, if the outcome of the game is a winning outcome and a base award is determined as a function of the outcome of the game and a paytable, the base award is multiplied by the multiplier and awarded to the player.
- In another embodiment, volatility factor is a table of multiplier. For example, the first volatility factor may be a first table of multipliers and the second volatility factor may be a second table of multipliers. Each multiplier in a table has a weight and corresponding odds of being used. One a table of multiplier has been set as the volatility factor, one of the multipliers in the table is randomly chosen. The randomly chosen multiplier is then. Generally, a new multiplier is randomly chosen each play of the game.
- In one embodiment the game is a
primary game 76. In another embodiment the game is asecondary game 70. - The base award may be a set amount, a progressive award, a number of free spins or any other type of award.
- In a second embodiment, the
controller 40 sets the volatility factor to a first volatility value and sets a number of plays of theprimary game 76 to a first random number of games. A counter is used to count the number of plays of theprimary game 76 played. - The
controller 40 allows the player to make a wager using theuser interface 13 and displays theprimary game 76 on thedisplay device primary game 76 is randomly selected and displayed. An award is award to the player if the an outcome of the first instance of the game, to display the outcome on thedisplay device primary game 76 if the outcome of theprimary game 76 is a winning outcome. - The controller displays the
secondary game 70 on the display device. An outcome of thesecondary game 70 is randomly selected and displayed. A second award is awarded to the player if the outcome of thesecondary game 70 is a winning outcome. The second award is a function of the volatility factor. - The counter is incremented. If the counter is equal to the number of games played, the counter is reset, the volatility factor is set to another volatility value, the number of plays is set to another random number of games played.
- In another aspect of the present invention, a method of provides a game to a player. The method includes the steps of (a) providing a
gaming machine 14 having adisplay user interface 13, (b) setting a volatility factor to a first volatility value, (c) setting a number of plays to a first random number of games, and (d) establishing a counter of a number of games played. The player is allowed to place or make a wager (step (e)). - The game is displayed (step(f)), an outcome of the game is randomly selected (step(g)) and an award is awarded to the player as a function of the outcome of the game and the volatility factor (step(h)).
- The method also includes the steps of (i) incrementing the counter, (j) comparing the counter to the number of games played and, if the counter is equal to the number of games played: (1) resetting the counter, (2) setting the volatility factor to another volatility value, and (3) setting the number of plays to another random number of games played. Steps (e)-(j) may be repeated.
- In a fourth aspect of the present invention, a method provides primary and
secondary games gaming machine 14 including adisplay user interface 13, (2) setting a volatility factor to a first volatility value, (3) setting a number of plays of theprimary game 76 to a first random number of games, and (4) establishing a counter of a number of games played of theprimary game 76. The player is allowed player to make a wager on theprimary game 76 using the user interface 13 (step (5)). An outcome of theprimary game 76 is randomly selected (step (6)) and displayed (step (7)). - If the outcome of the
primary game 76 is a winning outcome (step (8)), the player is awarded aprimary award 76 as a function of the outcome, the wager made by the player, and a predetermined paytable (step (9)). If a triggering condition has occurred in theprimary game 76, asecondary game 70 is initiated (step (10)). Thesecondary game 70 includes the steps of (a) randomly selecting an outcome of the game and displaying the outcome on thedisplay device - Steps (5)-(10) may be repeated.
- With reference to
FIGS. 3-6 , the present invention is used to implement a game titled “Rock Around the Clock”. In the Rock around the Clock game, the player advances to bonus time, with every bought game, i.e., theprimary game 76. - With specific reference to
FIG. 3 , when theclock 72 strikes BONUS TIME, a feature game, 76 is awarded. All feature games are multiplied by the current bonus time multiplier (indicated by the arrow on the clock). Duringprimary game 76 play theMascot 74 may randomly increase the multiplier to a higher value. Different multiplier tables are used based on the number of games played. Each table has the same Expected Value (EV) but different volatility. Two examples are shown in Tables 1 and 2. Table 1 is used for a first random number of games, e.g., game number 1-49 and Table 2 is used for a random number of games thereafter. - The game number is reset back to 0 once bonus time is triggered.
-
TABLE 1 Multiplier Weight 40x 0 20x 0 8x 0 3x 200 2x 400 1x 200 Bonus Multiplier Table (EV = 2, σ = 3.32) -
TABLE 2 Multiplier Weight 40x 4 20x 10 8x 50 3x 200 2x 400 1x 832 Bonus Multiplier Table (EV = 2, σ = 15.21) - Both tables have an average multiplier value of 2×. Table 2 has greater volatility (more dispersion in multiplier award). The idea is that as the player invests more money by playing more games, the chance for a large multiplier increases once 50 games have been played.
- When the number of games played has reached this random number of games played, the
Mascot 74 changes the multiplier, e.g., from 2× to 8× (seeFIGS. 4-6 ). - Other aspect and features of the present invention can be obtained from a study of the drawings, the disclosure, and the appended claims.
