cause a display of the randomly selected symbols at a plurality of symbol display positions,
determine whether said displayed randomly selected symbols form any of a plurality of winning symbol combinations, and
responsive to determining that the displayed randomly selected symbols form at least one of the winning symbol combinations, for each formed winning symbol combination:
independent of any player input to reposition any of the displayed randomly selected symbols, remove at least one of the displayed randomly selected symbols that forms that winning symbol combination, and
for each removed symbol:
select one of the plurality of symbols as a replacement for that removed symbol, and
cause a display of that selected symbol.
2. The gaming system of claim 1 , wherein when executed by the processor, the instructions cause the processor to, for at least one of any removed symbols, cause a display of a repositioning of at least one remaining of the displayed randomly selected symbols to the symbol display position of that removed symbol.
3. The gaming system of claim 1 , wherein when executed by the processor, the instructions cause the processor to, for at least one of any removed symbols, cause the display of that selected symbol at the symbol display position of that removed symbol.
4. The gaming system of claim 1 , wherein when executed by the processor after causing a display of selected symbols for each removed symbol, the instructions cause the processor to:
determine whether said displayed selected symbols form any of the plurality of winning symbol combinations, and
responsive to determining that the displayed selected symbols form at least one of the winning symbol combinations, for each formed winning symbol combination:
independent of any player input to reposition any of the displayed selected symbols, remove at least one of the displayed selected symbols that forms that winning symbol combination, and
for each removed symbol:
select one of the plurality of symbols as a replacement for that removed symbol, and
cause a display of that selected symbol.
5. The gaming system of claim 1 , wherein when executed by the processor, the instructions cause the processor to: responsive to a physical item being received via an acceptor, establish a credit balance based, at least in part, on a monetary value associated with the received physical item, and responsive to a cashout input being received via a cashout device, cause an initiation of any payout associated with the credit balance.
6. The gaming system of claim 5 , which comprises the acceptor, and the cashout device.
7. The gaming system of claim 1 , which comprises a display device, wherein when executed by the processor, the instructions cause the processor to cause the display device to display the randomly selected symbols at the plurality of symbol display positions.
8. The gaming system of claim 1 , wherein the selected symbol for each removed symbol comprises a randomly selected symbol.
9. A method of operating a gaming system, said method comprising:
responsive to a placement of a wager, for a play of a game:
randomly selecting, by a processor executing instructions, at least two of a plurality of symbols,
causing a display of the randomly selected symbols at a plurality of symbol display positions,
determining, by the processor executing instructions, whether said displayed randomly selected symbols form any of a plurality of winning symbol combinations, and
responsive to determining that the displayed randomly selected symbols form at least one of the winning symbol combinations, for each formed winning symbol combination:
independent of any player input to reposition any of the displayed randomly selected symbols, removing at least one of the displayed randomly selected symbols that forms that winning symbol combination, and
for each removed symbol:
selecting, by the processor executing instructions, one of the plurality of symbols as a replacement for that removed symbol, and
causing a display of that selected symbol.
10. The method of claim 9 , which comprises, for at least one of any removed symbols, causing a display of a repositioning of at least one remaining of the displayed randomly selected symbols to the symbol display position of that removed symbol.
11. The method of claim 9 , which comprises, for at least one of any removed symbols, causing the display of that selected symbol at the symbol display position of that removed symbol.
12. The method of claim 9 , which comprises, after causing a display of selected symbols for each removed symbol:
determining, by the processor executing instructions, whether said displayed selected symbols form any of the plurality of winning symbol combinations, and
responsive to determining that the displayed selected symbols form at least one of the winning symbol combinations, for each formed winning symbol combination:
independent of any player input to reposition any of the displayed selected symbols, removing at least one of the displayed selected symbols that forms that winning symbol combination, and
for each removed symbol:
selecting, by the processor executing instructions, one of the plurality of symbols as a replacement for that removed symbol, and
causing a display of that selected symbol.
13. The method of claim 9 , wherein a credit balance is decreasable based on the placed wager, said credit balance being increasable via an acceptor of a physical item associated with a monetary value, and said credit balance being decreasable via a cashout device.
14. The method of claim 13 , wherein the gaming system comprises the acceptor, and the cashout device.
15. The method of claim 9 , wherein the gaming system comprises a display device, and which comprises causing the processor to execute instructions to cause the display device to display the randomly selected symbols at the plurality of symbol display positions.
16. The method of claim 9 , wherein the selected symbol for each removed symbol comprises a randomly selected symbol.
17. The method of claim 9 , which is provided through a data network.
