Abstract

Claims (38)

1. A method of operating a gaming machine, the method comprising the operations of:

accepting, via a value input device, a physical item associated with a monetary value to establish a monetary balance;

conducting, by game-logic circuitry, a game including:

presenting, by a presentation assembly, a plurality of symbol-bearing reels, an array, and a plurality of persistent elements, each persistent element having an associated game feature and an associated accumulation symbol;

spinning and stopping the plurality of reels to land symbols from the reels in the array; and

in response to the landed symbols including at least one accumulation symbol:

animating an addition of the at least one accumulation symbol to its associated persistent element; and

randomly determining whether or not to award the game feature associated with the persistent element associated with the at least one accumulation symbol; and

in response to awarding the game feature associated with the persistent element associated with the at least one accumulation symbol, implementing the game feature via the game-logic circuitry, wherein the implementing comprises applying changes associated with the game feature to game conditions currently in effect for a set of bonus spins comprising a combination of purchased spins and free spins and removing the applied changes upon completion of the bonus spins, wherein the changes associated with the game feature comprise, upon the landed symbols including a catalyst symbol, awarding values borne by one or more value-bearing symbols landed in the array; and

receiving, via at least one of one or more electronic input devices, a cash out input that initiates a payout from the monetary balance via a value output device.

2. The method of claim 1 , wherein the set of bonus spins comprises a subset of free spins preceded by a subset of purchased spins.

3. The method of claim 1 , wherein the set of bonus spins comprises a subset of purchased spins preceded by a subset of free spins.

4. The method of claim 1 , wherein the set of bonus spins comprises a predetermined number of spins.

5. The method of claim 1 , wherein the set of bonus spins comprises a randomly determined number of spins.

6. The method of claim 1 , wherein the gaming machine is regulatorily approved and primarily dedicated to playing a wagering game.

7. The method of claim 1 , wherein the animating operation includes increasing a size of the persistent element or a volume of items therein.

8. The method of claim 7 , wherein randomly determining whether or not to award the game feature associated with the persistent element is based, at least in part, on the size of the persistent element or the volume of items therein.

9. The method of claim 1 , wherein the changes associated with the game features comprise modification of the symbols borne by the plurality of reels, the modification including a wild multiplier.

10. A gaming machine comprising:

a presentation assembly;

a value input device configured to accept a physical item associated with a monetary value to establish a credit balance;

a value output device configured to dispense a payout from the credit balance in response to a cashout input; and

game-logic circuitry configured to perform the operations of:

conducting a game including:

presenting, by the presentation assembly, a plurality of symbol-bearing reels, an array, and a plurality of persistent elements, each persistent element having an associated game feature and an associated accumulation symbol;

spinning and stopping the plurality of reels to land symbols from the reels in the array; and

in response to the landed symbols including at least one accumulation symbol:

animating an addition of the at least one accumulation symbol to its associated persistent element;

randomly determining whether or not to award the game feature associated with the persistent element associated with the at least one accumulation symbol; and

in response to awarding the game feature associated with the persistent element associated with the at least one accumulation symbol, implementing the game feature via the game-logic circuitry, wherein the implementing comprises applying changes associated with the game feature to game conditions currently in effect for a set of bonus spins comprising a combination of purchased spins and free spins and removing the applied changes upon completion of the bonus spins, wherein the changes associated with the game feature comprise, upon the landed symbols including a catalyst symbol, awarding values borne by one or more value-bearing symbols landed in the array.

11. The gaming machine of claim 10 , wherein the set of bonus spins comprises a subset of free spins preceded by a subset of purchased spins.

12. The gaming machine of claim 10 , wherein the set of bonus spins comprises a subset of purchased spins preceded by a subset of free spins.

13. The gaming machine of claim 10 , wherein the set of bonus spins comprises a predetermined number of spins.

14. The gaming machine of claim 10 , wherein the set of bonus spins comprises a randomly determined number of spins.

15. The gaming machine of claim 10 , wherein the gaming machine is regulatorily approved and primarily dedicated to playing a wagering game.

16. The gaming machine of claim 10 , wherein the animating operation includes increasing a size of the persistent element or a volume of items therein.

17. The gaming machine of claim 16 , wherein randomly determining whether or not to award the game feature associated with the persistent element is based, at least in part, on the size of the persistent element or the volume of items therein.

18. The gaming machine of claim 10 , wherein the changes associated with the game features comprise modification of the symbols borne by the plurality of reels, the modification including a wild multiplier.
