Abstract

Claims (34)

1. A method for use with a gaming machine including a processor that is arranged to provide a spinning reel game, the method comprising:

stopping, using the processor, a spinning reel in order to display a symbol to a player;

determining, using the processor, whether the symbol is a specified symbol and is adjacent another symbol that was held in a fixed display position while the reel was spinning; and, if so

holding, using the processor, the symbol and the other symbol in fixed display positions during at least one subsequent reel spin.

2. A method according to claim 1 wherein the player is awarded an award if a winning outcome is displayed on the reels, the method comprising:

increasing the award if the winning outcome comprises at least one of the held symbols.

3. A method according to claim 1 wherein the held symbol is a wild symbol.

4. A method according to claim 3 wherein the specified symbol is a wild symbol that substitutes for one or more other symbols in assessing whether a winning outcome has occurred.

5. A method according to claim 1 wherein the adjacent specified symbol has a multiplier effect on the award.

6. A method according to claim 5 wherein the multiplier effect increases dependent on a quantity of the specified symbols that are adjacent one another on the displayed reels.

7. A method according to claim 5 wherein the multiplier effect is capped.

8. A method according to claim 1 wherein the resultant position has four edges and a specified symbol in the resultant position has a multiplier effect if the resultant position shares an edge with an adjacent resultant position in which an adjacent specified symbol is displayed.

9. A method according to claim 1 wherein the resultant position has four edges and a specified symbol in the resultant position has a multiplier effect if the resultant position shares an edge or a corner with an adjacent resultant position in which an adjacent specified symbol is displayed.

10. A method according to claim 1 wherein the specified symbol is represented as superimposed on underlying symbols as the reel carrying the specified symbol is re-spun.

11. A method according to claim 1 wherein the specified symbol is held in the resultant position for a series of spinning reel games.

12. A method according to claim 1 wherein the specified symbol, if spun up in a bought game, is held in the resultant position for a predetermined number of bought spinning reel games.

13. A method according to claim 1 wherein the spun-up specified symbol is held in the resultant position if an eligibility criterion is satisfied.

14. A method according to claim 13 wherein the eligibility criterion is the occurrence of a trigger condition on the reels.

15. A method according to claim 13 wherein the eligibility criterion is the payment of an ante-bet by a player of the gaming machine.

16. A method according to claim 13 wherein the satisfaction of the eligibility criterion commences a series of free games in which all specified symbols that are spun up are held.

17. A gaming machine arranged to provide a spinning reel game in which symbols are spun up on a plurality of reels to form at least one outcome and, if a winning outcome occurs, the gaming machine awards an award, the gaming machine comprising at least one game controller including a processor arranged to:

stop a spinning reel in order to display a symbol to a player;

determine whether the symbol is a specified symbol and is adjacent another symbol that was held in a fixed display position while the reel was spinning; and, if so hold the symbol and the other symbol in fixed display positions during at least one subsequent reel spin.

18. A non-transitory computer readable storage medium comprising machine-readable instructions which, when executed by a processor, control operation of a data processing apparatus on which the program code executes to perform a method for use with a gaming machine that is arranged to provide a spinning reel game, the method comprising:

stopping a spinning reel in order to display a symbol to a player;

determining whether the symbol is a specified symbol and is adjacent another symbol that was held in a fixed display position while the reel was spinning; and, if so

holding the symbol and the other symbol in fixed display positions during at least one subsequent reel spin.

19. A non-transitory computer readable storage medium comprising machine-readable instructions which, when executed by a processor, control operation of a data processing apparatus on which the program code executes to perform a method for use with a gaming machine that is arranged to provide a spinning reel game, the method comprising:

stopping a spinning reel in order to display a symbol to a player;

determining whether the symbol is a specified symbol and is adjacent another symbol that was held in a fixed display position while the reel was spinning; and, if so

holding the symbol and the other symbol in fixed display positions during at least one subsequent reel spin.

20. A computer readable storage medium according to claim 19 wherein the player is awarded an award if a winning outcome is displayed on the reels, the method further comprising:

increasing the award if the winning outcome comprises at least one of the held symbols.

21. A computer readable storage medium according to claim 19 wherein the held symbol is a wild symbol.
