Gaming machine including one or more grouped held value symbols
Disclosed is a gaming system including a gaming machine primarily dedicated for use in playing at least one regulated casino wagering game. In response to a triggering event, the gaming system initiates play of a feature game including a plurality of standard symbols and value symbols, the value symbols being associated with one or more values. One or more of the value symbols are held in place in a group on a display device, the standard symbols then replaced with respective replacement symbols randomly selected from the plurality of standard and value symbols. In response to the replacement symbols including another value symbol, the value symbol is added to the group and at least one of the values of the symbols previously in the group is modified. An award based on the current cumulative value of the held value symbols is determined at the conclusion of the feature game.

game-logic circuitry configured to:
detect, via at least one of the one or more electronic input devices, a physical item associated with a monetary value that establishes a credit balance;
initiate the casino wagering game in response to an input indicative of a wager covered by the credit balance;
in response to a triggering event:
initiate play of a feature game including:
randomly select a set of symbols from a plurality of symbols, the plurality of symbols including standard symbols and value symbols;
display the set of symbols in an array on the electronic display device, the value symbols being associated with one or more values;
hold one or more of the value symbols in place in a group on the electronic display device;
graphically indicate the group on the electronic display device via a single border surrounding all of the symbols in the group;
replace one or more of the standard symbols with respective replacement symbols randomly selected from the plurality of symbols;
only in response to the replacement symbols including another one or more of the value symbols in an array position immediately adjacent to the border,
add the another one or more of the value symbols to the group to increase the number of value symbols in the group;
expand the border to include the another one or more of the value symbols added to the group;
modify at least one of the values of the symbols previously in the group;
modify the credit balance by an amount comprising a total of the values of the symbols in the group; and
receive, via at least one of the one or more electronic input devices, a cashout input that initiates a payout from the credit balance.
2. The gaming system of claim 1 , wherein a value initially associated with each held value symbol is either randomly selected from a set of possible values or is fixed value.
3. The gaming system of claim 1 , wherein the game-logic circuitry is configured to increase by a fixed amount one or more values associated with the held value symbols.
4. The gaming system of claim 1 , wherein in response to the triggering event, the game-logic circuitry is configured to predetermine a number of plays of the feature game, wherein in each play the game-logic circuitry is configured to repeat the holding, replacing and adding operations in response to the replacement symbols including another one or more of the value symbols in an array position immediately adjacent to the border.
5. The gaming system of claim 4 , wherein the number of plays is reset to the predetermined number in response to the replacement symbols including another one or more of the value symbols being added to the group.
6. The gaming system of claim 1 , wherein the one or more value symbols added to the group are adjacent to one or more of the value symbols previously in the group.
7. A gaming system, comprising:
a regulated gaming machine primarily dedicated to playing at least one casino wagering game, the gaming machine including an electronic display device and one or more electronic input devices; and
means for:
detecting, via at least one of the one or more electronic input devices, a physical item associated with a monetary value that establishes a credit balance;
initiating the casino wagering game in response to an input indicative of a wager covered by the credit balance;
in response to a triggering event:
initiating play of a feature game including:
randomly selecting a set of symbols from a plurality of symbols, the plurality of symbols including standard symbols and value symbols;
displaying the set of symbols in an array on the electronic display device, the value symbols being associated with one or more values;
holding one or more of the value symbols in place in a group on the electronic display device;
graphically indicating the group on the electronic display device via a single border surrounding all of the symbols in the group;
replacing one or more of the standard symbols with respective replacement symbols randomly selected from the plurality of symbols;
only in response to the replacement symbols including another one or more of the value symbols in an array position immediately adjacent to the border, adding the another one or more of the value symbols to the group to increase the number of value symbols in the group, expanding the border to include the another one or more of the value symbols added to the group and modifying at least one of the values of the symbols previously in the group;
modify the credit balance by an amount comprising a total of the values of the symbols in the group; and
receiving, via at least one of the one or more electronic input devices, a cashout input that initiates a payout from the credit balance.
8. The gaming system of claim 7 , wherein a value initially associated with each held value symbol is randomly selected from a set of possible values or is a fixed value.
9. The gaming system of claim 7 , wherein the game-logic circuitry is configured to increase by a fixed amount one or more values associated with the held value symbols.
10. The gaming system of claim 7 , including means for, in response to the triggering event, predetermining a number of plays of the feature game, wherein in each play the holding, replacing and adding operations are repeated in response to the replacement symbols including another one or more of the value symbols in an array position immediately adjacent to the border.
11. The gaming system of claim 10 , wherein the number of plays is reset to the predetermined number in response to the replacement symbols including another one or more of the value symbols being added to the group.
12. The gaming system of claim 7 , wherein the one or more value symbols added to the group are adjacent to one or more of the value symbols previously in the group.
13. A method of operating a gaming system, the gaming system including game-logic circuitry and a regulated gaming machine, the gaming machine primarily dedicated to playing at least one casino wagering game, the gaming machine including an electronic display device and a value input device, the method comprising:
detecting, via at least one of the one or more electronic input devices, a physical item associated with a monetary value that establishes a credit balance;
initiating the casino wagering game in response to an input indicative of a wager covered by the credit balance;
in response to a triggering event:
initiating play of a feature game including:
randomly selecting a set of symbols from a plurality of symbols, the plurality of symbols including standard symbols and value symbols;
displaying the set of symbols in an array on the electronic display device, the value symbols being associated with one or more values;
holding one or more of the value symbols in place in a group on the electronic display device;
