Gaming systems and methods using dynamic modifiers
A gaming system includes a gaming machine and game-logic circuitry. The gaming machine includes a display device configured to display (i) a symbol array comprising a plurality of symbols and (ii) a modifier array comprising a plurality of modifiers. The game-logic circuitry is configured to select, for a plurality of rounds of populating the symbol array with symbols, a subarray of the modifier array. The selected subarray is displayed by the display device. The game-logic circuitry is further configured to generate, using a random-number generator, one or more random numbers to determine an outcome of a round of the plurality of rounds, modify the subarray in response to the outcome of the round including a selection symbol, and apply, in response to a trigger round of the plurality of rounds, the modifiers of the subarray to an outcome associated with the trigger round.
1. A gaming system comprising:
a gaming machine comprising a display device configured to display a symbol array comprising a plurality of symbols and a modifier array comprising a plurality of modifiers and blanks; and
game-logic circuitry configured to:
select, for a plurality of rounds of populating the symbol array with symbols, a subarray of the modifier array, the selected subarray displayed by the display device;
generate, using a random-number generator of the game-logic circuitry, one or more random numbers to determine an outcome of a round of the plurality of rounds;
in response to the outcome of the round including an upgrade symbol, upgrading one or more modifiers within the modifier array;
in response to the outcome of the round including a swap symbol, swap modifiers between two or more array positions within the modifier array; and
in response to a trigger round of the plurality of rounds, cause the display device to apply the modifiers of the subarray to an outcome associated with the trigger round.
2. The gaming system of claim 1 , wherein the trigger round is a final round of the plurality of rounds.
3. The gaming system of claim 1 , wherein the trigger round is a randomly selected round of the plurality of rounds.
4. The gaming system of claim 1 , wherein a new subarray is selected from the modifier array in response to the outcome associated with the trigger round.
5. The gaming system of claim 1 , wherein the plurality of modifiers includes a wild symbol modifier to replace a symbol populating the symbol array with a wild symbol.
6. The gaming system of claim 1 , wherein the plurality of modifiers includes a multiplier modifier for increasing an award for a winning outcome.
7. The gaming system of claim 1 , wherein the plurality of modifiers includes a blank that does not apply any modifier or change when the modifiers of the subarray are applied to an outcome associated with the trigger round.
8. The gaming system of claim 7 , wherein the game-logic circuitry is further configured to, in response to the outcome of the round including a blank elimination symbol, cause the display device to replace one or more modifiers within the selected subarray with a non-blank modifier.
9. The gaming system of claim 1 , wherein the display device is configured to display the modifier array as a symbol-bearing reel.
10. The gaming system of claim 1 , wherein the display device is configured to display the modifier array as a wheel.
11. A method of using a gaming system comprising game-logic circuitry and a gaming machine, the gaming machine having a display device in communication with the game-logic circuitry, the method comprising:
displaying, via the display device, a symbol array comprising a plurality of symbols and a modifier array comprising a plurality of modifiers;
selecting, by the game-logic circuitry and for a plurality of rounds of populating the symbol array with symbols, a subarray of the modifier array, the selected subarray displayed by the display device;
generating, using a random-number generator of the game-logic circuitry, one or more random numbers to determine an outcome of a round of the plurality of rounds;
in response to the outcome of the round including an upgrade symbol, upgrading, by the game-logic circuitry, one or more modifiers within the modifier array;
in response to the outcome of the round including a swap symbol, swapping, by the game-logic circuitry, modifiers between two or more array positions within the modifier array; and
in response to a trigger round of the plurality of rounds, causing, by the game-logic circuitry, the display device to apply the modifiers of the subarray to an outcome associated with the trigger round.
12. The method of claim 11 , wherein the trigger round is a final round of the plurality of rounds.
13. The method of claim 11 , wherein the trigger round is a randomly selected round of the plurality of rounds.
14. The method of claim 11 , wherein a new subarray is selected from the modifier array in response to the outcome associated with the trigger round.
15. The method of claim 11 , wherein the plurality of modifiers includes a wild symbol modifier to replace a symbol populating the symbol array with a wild symbol.
16. The method of claim 11 , wherein the plurality of modifiers includes a multiplier modifier for increasing an award for a winning outcome.
17. The method of claim 11 , wherein the plurality of modifiers includes a blank that does not apply any modifier or change when the modifiers of the subarray are applied to an outcome associated with the trigger round.
18. The method of claim 17 , wherein, in response to the outcome of the round including a blank elimination symbol, causing, by the game-logic circuitry, the display device to replace one or more modifiers within the selected subarray with a non-blank modifier.
19. The method of claim 11 , wherein the modifier array is displayed as a symbol-bearing reel.
20. The method of claim 11 , wherein the modifier array is displayed as a wheel.
