Wagering game having free spin feature with variable quantities of reel arrays
View Patent ↗A gaming system for conducting a wagering game includes at least one input device, at least one display device, at least one processor, and at least one memory device storing instructions. The instructions, when executed by the at least one processor, cause the gaming system to receive a wager for playing the wagering game, and trigger a free-spin event in which a plurality of free spins is awarded. For a first spin, a first number of arrays is randomly determined, displayed, and evaluated to determine whether an award condition is present. For a second spin, a second number of arrays is randomly determined, displayed, and evaluated to determine whether an award condition is present. The second number of arrays is non-equal to the first number of arrays. Any awards associated with each determined award condition are provided.

at least one memory device storing instructions that, when executed by the at least one processor, cause the gaming system to:
receive a wager for playing a wagering game,
trigger a free-spin event in which a plurality of free spins is awarded,
randomly determine a first number of arrays for a first spin of the plurality of free spins,
display the first number of arrays on the at least one display device,
evaluate each of the first number of arrays to determine whether an award condition is present,
randomly determine a second number of arrays for a second spin of the plurality of free spins, the second number of arrays being non-equal to the first number of arrays,
display the second number of arrays on the at least one display device,
evaluate each of the second number of arrays to determine whether an award condition is present, and
provide any awards associated with each determined award condition.
2. The gaming system of claim 1 , wherein each of the arrays in the first number of arrays is of the same configuration and each of the arrays in the second number of arrays is of the same configuration.
3. The gaming system of claim 1 , wherein at least two arrays of the first and second number of arrays have at least one variable feature selected from a group consisting of variable symbol sets, variable reel weightings, variable line counts, and variable array forms.
4. The gaming system of claim 1 , wherein the random determination for the first number of arrays is determined by a first selection of a mystery symbol and the random determination for the second number of arrays is determined by a second selection of a mystery symbol.
5. The gaming system of claim 1 , wherein the instructions further cause the system to associate at least one game enhancement for each of the first number of arrays, the game enhancement being capable of enhancing an outcome for each associated array of the first number of arrays.
6. The gaming system of claim 5 , wherein the at least one game enhancement is the same game enhancement for each array of the first number of arrays.
7. The gaming system of claim 5 , wherein the at least one game enhancement is selected from a plurality of potential game enhancements and the random determination for the first number of arrays is impacted by which of the plurality of potential game enhancements is selected.
8. The gaming system of claim 7 , wherein the first number of arrays is selected from a group of numbers including a large number and a small number, the at least one game enhancement being selected from a plurality of potential game enhancements, the plurality of game enhancements including a great enhancement and a good enhancement, the great enhancement, on average, yielding more valuable award conditions than the good enhancement.
9. The gaming system of claim 8 , wherein a probability of selecting the large number is larger if the at least one game enhancement is selected to be the good enhancement than if the at least one game enhancement is selected to be the great enhancement.
10. The gaming system of claim 1 , wherein the instructions further cause the system to display the reel arrays generally simultaneously on the at least one display device.
11. A computer-implemented method in a gaming system, comprising:
receiving a wager in response to an input via at least one input device;
in response to receiving the wager, initiating, by at least one of one or more processors, a play of a wagering game;
representing the play, by at least one of the one or more processors, in a form of one or more reel arrays;
randomly determining, by at least one of the one or more processors, a first number of arrays for a first spin of a plurality of free spins;
displaying the first number of arrays on at least one display device;
evaluating, by at least one of the one or more processors, each of the first number of arrays to determine whether an award condition is present;
randomly determining, by at least one of the one or more processors, a second number of arrays for a second spin of the plurality of free spins, the second number of arrays being non-equal to the first number of arrays;
displaying the second number of arrays on the at least one display device;
evaluating, by at least one of the one or more processors, each of the second number of arrays to determine whether an award condition is present; and
providing, by at least one of the one or more processors, any awards associated with each determined award condition.
12. The computer-implemented method of claim 11 , wherein the random determination for the first number of arrays is determined by a first selection of a mystery symbol and the random determination for the second number of arrays is determined by a second selection of a mystery symbol.
13. The computer-implemented method of any of claims 11 , further comprising causing, by at least one of the one or more processors, the system to associate at least one game enhancement for each of the first number of arrays, the game enhancement being capable of enhancing an outcome for each associated array of the first number of arrays.
14. The computer-implemented method of any of claims 13 , wherein the at least one game enhancement is the same game enhancement for each array of the first number of arrays.
15. The computer-implemented method of any of claims 11 , wherein the first number of arrays is selected from a group of numbers including a large number and a small number, at least one game enhancement being selected from a plurality of potential game enhancements, a probability of selecting the large number being larger if the at least one game enhancement is selected to be a good enhancement than if the at least one game enhancement is selected to be a great enhancement, the great enhancement, on average, yielding more valuable award conditions than the good enhancement.
16. One or more machine-readable non-transitory storage media including instructions which, when executed by one or more processors, cause the one or more processors to perform operations comprising:
receiving a wager for playing a wagering game;
triggering a free-spin event in which a plurality of free spins is awarded, the plurality of free spins including a first spin and a second spin;
prior to evaluating the first spin, randomly generating a first number of first reel arrays;
displaying the first number of first reel arrays on at least one display device;
prior to evaluating the second spin, randomly generating a second number of second reel arrays; and
displaying the second number of second reel arrays on the at least one display device.
17. The machine-readable non-transitory storage media of claim 16 , the operations further comprising:
displaying a plurality of mystery symbols on the at least one display device;
in response to receiving a first player selection of a first mystery symbol of the plurality of mystery symbols, revealing the first number of first reel arrays and a first game enhancement;
in response to receiving a second player selection of a second mystery symbol of the plurality of mystery symbols, revealing the second number of second reel arrays and a second game enhancement; and
enhancing outcomes of the first reel arrays with the first game enhancement and outcomes of the second reel arrays with the second game enhancement.
18. The machine-readable non-transitory storage media of claim 16 , the operations further comprising selecting, for each spin of the plurality of free spins, a game enhancement from a plurality of game enhancement, a probability of generating the first number and the second number being dependent on the game enhancement.
19. The machine-readable non-transitory storage media of claim 16 , the operations further comprising receiving a player selection of a game enhancement for enhancing one or more outcomes of the first reel arrays and second reel arrays.
