Abstract
An electronic gaming device including a display device operable to display a portion of a plurality of reels, and a controller. The controller includes a processor to associate a first lookup table and a second lookup table with a first symbol and a second symbol from a first reel, respectively, select a first entry in the first table that satisfies a target threshold, convert the first symbol with the first entry, and evaluate the portion of the plurality of reels for a win combination that satisfies the target threshold.
Claims20
An electronic gaming device comprising:
- a display device operable to display at least a portion of a plurality of reels at a plurality of symbol positions;
- and
- a controller comprising a processor and memory storing a symbol set including a plurality of game symbols and special symbols, a plurality of lookup tables, each of the plurality of lookup tables including a range of credit values, and instructions, which, when executed, cause the processor to at least:
- access the memory during game play for a first table and a second table of the plurality of lookup tables with a first special symbol and a second special symbol from a first reel of the plurality of reels, respectively, wherein the range of credit values for the first table differs from the range of credit values for the second table,
- control the display device to animate a first converted symbol formed from the first special symbol and a first credit value based on one or more random numbers generated by a random number generator, and the first table,
- control the display device to animate a second converted symbol formed from the second special symbol and a second credit value based on the random numbers generated, and the second table, and
- control the electronic gaming device to generate a payout based on an outcome formed from a subset of game symbols including the first converted symbol with the first credit value and the second converted symbol with the second credit value, and based on a stop position of the first reel that includes the first converted symbol and the second converted symbol.
A method for controlling a gaming system that comprises a plurality of devices, and a server being coupled to the plurality of devices and including a processor and a memory storing a plurality of game symbols and special symbols on a set of reel strips, a plurality of lookup tables, each of the plurality of lookup tables including a plurality of entries having a range of values, wherein the range of values for a first table of the plurality of lookup tables differs from the range of values for a second table of the plurality of lookup tables, and instructions, which, when executed, cause the processor at least to initiate a game, the method comprising:
- controlling the processor to access the memory during play of the game for the first table and the second table with a first special symbol and a second ame special symbol on a first reel strip of the set of reel strips, respectively;
- controlling a first device to animate the first special symbol and the second special symbol being overlaid with a first entry from the first table and a second entry from the second table, respectively, based on one or more random numbers generated by a random number generator;
- controlling the first device to animate a subset of the plurality of game symbols being selected for each reel strip of the set of reel strips based on the random numbers generated;
- and
- controlling the first device to animate a win when a win combination exists across the set of reel strips being displayed including the first special symbol overlaid with the first entry and the second special symbol overlaid with the second entry based on the subset of the plurality of game symbols selected.
A non-transitory computer-readable medium comprising a plurality of game symbols and special symbols, a plurality of lookup tables, a plurality of reels, and instructions for conducting a game on a plurality of devices comprising a display device operable to display a portion of the plurality of reels, and a controller comprising a processor, and the instructions, when executed, cause the processor to perform the steps of:
- accessing the non-transitory computer-readable medium during game play for the plurality of lookup tables with the plurality of game symbols on a first reel of the plurality of reels, each of the plurality of lookup tables including a plurality of entries having a range of values, wherein the range of values for each of the plurality of lookup tables differs among each of the plurality of lookup tables;
- controlling the display device to animate the special symbols on the first reel being converted into one or more converted symbols with a subset of entries in the plurality of entries of the plurality of lookup tables associated with the first reel of the plurality of reels based on one or more random numbers generated by a random number generator;
- controlling the display device to display the portion of the plurality of reels responsive to the special symbols having been converted;
- and
- controlling the display device to generate a payout when the portion of the plurality of reels displayed includes a win combination.
