Gaming machine using multiple triggers to determine an award from a subset of displayed awards
A gaming system includes at least one input device adapted to receive a physical item associated with a monetary value that establishes a credit balance, an input indicative of a wager drawn on the credit balance for a wagering game, and a cashout input that initiates a payout from the credit balance. In response to a wager input, a wagering game is initiated that includes the spinning and stopping of a set of bonus reels through a plurality of bonus spins populating a bonus array with bonus symbols. The bonus reels comprise a combination of symbols reducing display processing requirements and improve mapping random numbers to displayed symbols for display during bonus spins having reduced durations. When completed, an award is determined based according to values associated with less than all of the bonus symbols displayed in a bonus outcome array.
1. A method of operating a gaming machine, the method comprising the operations of:
detecting, via a value input device, a physical item associated with a monetary value that establishes a credit balance;
receiving, via at least one of one or more electronic input devices, a wager that is drawn from the credit balance;
displaying, on an electronic display device, an array of symbol positions;
animating, on the electronic display device, a spin of symbol-bearing reels wherein the symbol-bearing reels are spun and stopped to populate the array with a plurality of symbols borne by the reels, the plurality of symbols including one or more value-bearing symbols, each value-bearing symbol displaying a respective value thereon;
in response to the plurality of symbols including a first feature symbol displaying a first feature indicator thereon, adding one or more additional value-bearing symbols to respective symbol positions in the array that do not already contain the one or more value-bearing symbols, each additional value-bearing symbol displaying a respective value thereon, the first feature indicator indicating the number of additional value-bearing symbols to be added;
in response to the plurality of symbols including a second feature symbol displaying a second feature indicator thereon, increasing the value borne by at least one of the one or more value-bearing symbols, the second feature indicator indicating a value by which the value borne by at least one of the one or more value-bearing symbols will be increased;
in response to the plurality of symbols including a third feature symbol displaying a third feature indicator thereon, immediately awarding the values borne by the one or more value-bearing symbols; and
in response to a cashout input via at least one of the one or more electronic input devices, dispensing, via a value output device, a payout from the credit balance.
2. The method of claim 1 , wherein at least one of the first, second, or third feature indicator includes a directional pointer visually indicating any symbol positions of the array impacted by the respective first, second, or third feature symbol.
3. The method of claim 1 , wherein the increasing the value borne by at least one of the one or more value-bearing symbols includes at least one of increasing the value by a predetermined amount, increasing the value by a random amount, or multiplying the value by a multiplier.
4. The method of claim 3 , wherein the value indicated by the second feature indicator is a credit amount or the multiplier.
5. The method of claim 1 , further including:
animating, on the electronic display device, additional free spins of the symbol-bearing reels;
holding the value-bearing symbols in the array during the additional free spins; and
in response to additional value-bearing symbols landing in the array as a result of the additional free spins, holding the additional value-bearing symbols in the array and incrementing a number of the additional free spins.
6. A gaming system, comprising:
a gaming machine including a value input device, a value output device, one or more electronic input devices, and an electronic display device configured to display an array of symbol positions; and
game-logic circuitry configured to perform the operations of:
detecting, via the value input device, a physical item associated with a monetary value that establishes a credit balance;
receiving, via at least one of the one or more electronic input devices, a wager that is drawn from the credit balance
animating, on the electronic display device, a spin of symbol-bearing reels wherein the symbol-bearing reels are spun and stopped to populate the array with a plurality of symbols borne by the reels, the plurality of symbols including one or more value-bearing symbols, each value-bearing symbol displaying a respective value thereon;
in response to the plurality of symbols including a first feature symbol displaying a first feature indicator thereon, adding one or more additional value-bearing symbols to respective symbol positions in the array that do not already contain the one or more value-bearing symbols, each additional value-bearing symbol displaying a respective value thereon, the first feature indicator indicating the number of additional value-bearing symbols to be added;
in response to the plurality of symbols including a second feature symbol displaying a second feature indicator thereon, increasing the value borne by at least one of the one or more value-bearing symbols, the second feature indicator indicating a value by which the value borne by at least one of the one or more value-bearing symbols will be increased;
in response to the plurality of symbols including a third feature symbol displaying a third feature indicator thereon, immediately awarding the values borne by the one or more value-bearing symbols; and
in response to a cashout input via at least one of the one or more electronic input devices, dispensing, via the value output device, a payout from the credit balance.
7. The gaming system of claim 6 , wherein the at least one of the first, second, or third feature indicator includes a directional pointer visually indicating any symbol positions of the array impacted by the respective first, second, or third feature symbol.
8. The gaming system of claim 6 , wherein the increasing the value borne by at least one of the one or more value-bearing symbols includes at least one of increasing the value by a predetermined amount, increasing the value by a random amount, or multiplying the value by a multiplier.
9. The gaming system of claim 8 , wherein the value indicated by the second feature indicator is a credit amount or the multiplier.
10. The gaming system of claim 6 , wherein the game-logic circuitry is further configured to perform the operations of:
animating, on the electronic display device, additional free spins of the symbol-bearing reels;
holding the value-bearing symbols in the array during the additional free spins; and
in response to additional value-bearing symbols landing in the array as a result of the additional free spins, holding the additional value-bearing symbols in the array and incrementing a number of the additional free spins.
