Abstract

An electronic method of operating a gaming system. The method includes selecting a plurality of symbols, displaying the selected symbols, and upon the displayed symbols including one or more designated symbols, retaining each displayed designated symbol for a subsequent game round at a respective symbol display position at which the designated symbol is displayed. The method also includes, in the subsequent game round, selecting, a plurality of symbols from the symbol data, upon a further designated symbol being selected for display at a symbol display position at which the retained designated symbol is displayed, modifying the retained designated symbol to indicate that a win containing the retained designated symbol will be increased, and upon the selected symbols in the subsequent game round corresponding to a winning outcome incorporating the modified retained designated symbol, making an award of an award value corresponding to the winning outcome modifier by the increase.

First claim

What is claimed is:

1. A gaming machine, comprising:
one or more display devices;
a game controller executing instructions from a memory, wherein execution of the instructions causes the game controller to at least:
present symbols at display positions of the one or more display devices, wherein the display positions comprise a first subset of display positions and a second subset of display positions; and
in response to a trigger condition:
present an update of the symbols in the second subset by holding each instance of a designated symbol in the second subset at its respective display position, and
presenting a respective replacement symbol at each display position in the second subset that is not holding the designated symbol.

2. The gaming machine of claim 1 , wherein execution of the instructions causes the game controller to, in response to at least one replacement symbol being the designated symbol, present another update of the symbols in the second subset by holding each instance of the designated symbol in the second subset at its respective display position, and presenting a respective replacement symbol at each display position in the second subset that is not holding the designated symbol.

3. The gaming machine of claim 2 , wherein execution of the instructions causes the game controller to continue updating the symbols in the second subset until an update fails to present at least one replacement symbol that is the designated symbol.

4. The gaming machine of claim 1 , wherein the first subset consists of a single column of display positions from the columns of display positions.

5. The gaming machine of claim 1 , wherein:
the first subset consists of a single leftmost column of display positions from the columns of display positions per a perspective of a player facing the one or more display devices; and
the second subset consists of remaining rightmost columns of display positions from the columns of display positions per the perspective of the player facing the one or more display devices.

6. The gaming machine of claim 1 , wherein:
the first subset consists of a single leftmost column of display positions from the columns of display positions per a perspective of a player facing the one or more display devices; and
the second subset consists of four rightmost columns of display positions from the columns of display positions per the perspective of the player facing the one or more display devices.

7. The gaming machine of claim 1 , comprising:
a credit input and
wherein execution of the instructions causes the game controller to establish a credit balance in response to the credit input interacting with a physical item having an associated credit value.

8. The gaming machine of claim 1 , wherein execution of the game controller causes the game controller to determine that the trigger condition has occurred in response to each column of display positions in the second subset including at least one instance of the designated symbol.

9. A method, comprising:
presenting symbols in display positions of one or more display devices, wherein the display positions include a first column of display positions and second columns of display positions; and
holding each instance of a designated symbol in the second columns at its respective display position; and
presenting a respective replacement symbol at each display position in the second columns that is not holding the designated symbol.

10. The method of claim 9 , comprising, in response to at least one replacement symbol being the designated symbol:
holding each instance of the designated symbol in the second columns at its respective display position; and
presenting a respective replacement symbol at each display position in the second columns that is not holding the designated symbol.

11. The method of claim 10 , comprising continually holding each instance of the designated symbol and presenting a respective replacement symbol until the presenting the respective replacement symbol fails to present at least one replacement symbol that is the designated symbol.

12. The method of claim 11 , comprising, in response to the presenting of the respective replacement symbol failing to present at least one replacement symbol:
presenting symbols at the first column of display positions; and
presenting an award based on the symbols in the first column of display positions and the symbols in the second columns of display positions.

13. The method of claim 9 , wherein the first column of display positions consists of a single column of display positions.

14. The method of claim 9 , wherein:
the first column of display positions consists of a single leftmost column of display positions per a perspective of a player facing the one or more display devices; and
the second columns of display positions consists of remaining rightmost columns of display positions per the perspective of the player facing the one or more display devices.

15. The method of claim 9 , wherein:
the first column of display positions consists of a single leftmost column of display positions per a perspective of a player facing the one or more display devices; and
the second column of display positions consists of four rightmost columns of display positions per the perspective of the player facing the one or more display devices.

16. The method of claim 9 , comprising, in response to failing to present at least one replacement symbol that is a designated symbol:
presenting symbols at the first column of display positions; and
presenting an award based on the symbols in the first column of display positions and the symbols in the second column of display positions.

17. A non-transitory computer readable storage medium comprising instructions that when executed cause a computing device to:
present symbols in display positions of one or more display devices, wherein the display positions include a first column of display positions and second columns of display positions; and
in response to a trigger condition:
hold each instance of a designated symbol in the second columns at its respective display position; and.
present a respective replacement symbol at each display position in the second columns that is not holding the designated symbol.

18. The non-transitory computer readable storage medium of claim 17 , wherein the instructions, when executed, cause the computing device, in response to at least one replacement symbol being the designated symbol, to:
hold each instance of the designated symbol in the second columns at its respective display position; and
presenting a respective replacement symbol at each display position in the second columns that is not holding the designated symbol.

19. The non-transitory computer readable storage medium of claim 17 , wherein the instructions, when executed, cause the computing device, in response to the replacement symbols failing to include at least one designated symbol, to:
present symbols at the first column of display positions; and
present an award based on the symbols in the first column of display positions and the symbols in the second column of display positions.

20. The non-transitory computer readable storage medium of claim 17 , wherein:
the first column of display positions consists of a single leftmost column of display positions per a perspective of a player facing the one or more display devices; and
the second columns of display positions consists of remaining rightmost columns of display
