Abstract: A credit-substitution symbol mechanic for a gaming device is described. The credit-substitution symbol mechanic randomly triggers an add-substitution symbol feature in a game instance with an initial reel area and randomly determines an expanded reel size for a plurality of reels to be displayed in an expanded reel area. The credit-substitution symbol mechanic randomly determines a substitution symbol to be added to a first reel of the plurality of reels and randomly determines the substitution symbol is a credit-substitution symbol. The credit-substitution symbol mechanic determines that the credit-substitution symbol is part of a payline. The credit-substitution symbol mechanic performs a first payout for the payline that pays out a payline award and performs a second payout for the payline that pays out a credit value of the credit-substitution symbol.

Abstract: An interactive electronic gaming machine that includes cumulative free games and a spinning wheel feature is disclosed. The interactive electronic gaming machine is a video slot machine game that includes a base game, cumulative free games, and a spinning wheel feature. The spinning wheel feature may include a plurality of values, selectable in response to a spin and stop of the spinning wheel. The selected value can include a multiplier associated with cumulative free games, which enhances a payout to a player of the interactive electronic gaming machine.

Abstract: A hold-and-spin feature is expanded and a potential game outcome is increased by triggering resetting of the remaining number of spins to different reset spin values based on the collection of a number of first respin triggering symbols. In order to control and manage the degree of randomness in having different numbers of reset spin values, and thus controlling game volatility and/or thus maintaining a target RTP, multiple reel strip types with different properties are used to select symbols for various positions in the symbol matrix. The multiple reel strip types may have different probabilities of selecting credit symbols, non-credit symbols, first respin triggering symbols, second triggering symbols, and so on.

Abstract: A system for electronic gaming displays a plurality of symbols for play of an electronic game, the symbols including at least one multi-triggering symbol associated with a plurality of chances to trigger a feature game by randomly determining that one chance of the chances causes triggering of the feature game. Upon triggering a plurality of meters for the feature game are displayed based upon one chance causing the feature game to be triggered, and for each remaining chance, a meter of the plurality of meters is increased resulting in an adjusted plurality of meters. A reel set for the feature game is generated based upon the adjusted plurality of meters and includes a plurality of reels, each including a plurality of symbols that are determined at least in part based on a final state of the adjusted plurality of meters. The feature game is initiated using the generated reel set.

Abstract: An electronic gaming machine includes a display device and a game controller configured to initiate a feature game that uses a plurality of mechanical reels and the display device, identify a number of feature game symbols initially available for use during the feature game, display a plurality of symbol columns, each symbol column of the plurality of symbol columns is associated with a reel, perform a spin of the reels, in response to the player initiating the play, distribute the number of feature game symbols into the plurality of symbol columns based on an output of a random number generator, each feature game symbol being displayed in a determined symbol column of the plurality of symbol columns, evaluate an outcome of the feature game based on attributing the feature game symbols to associated reels, and award credit to the player based on the evaluating.

Abstract: In an electronic gaming device, instances of a target symbol are swapped in to symbol positions of one or more reel strips using one or more index tables to identify the symbol positions at which to swap in the instances of the target symbol. The index table(s) can be configured to cluster instances of the target symbol according to a deterministic approach. Subsequently, spin results are determined for one or more spins of reels using the reel strips.

Abstract: An electronic gaming machine includes a display device, a player input interface configured to receive player input from a player; and a game controller configured to execute instructions. The instructions cause the processor to display a plurality of game reels including a first game reel type having a plurality of symbol positions and a second game reel type including a grouped symbol position. The instructions also cause the processor to display a bonus symbol in the grouped system position and, in response to displaying the bonus symbol, to display an expanded display area comprising at least one additional symbol position located above the reels of the first game reel type. The instructions further cause the processor to determine a game outcome based upon a plurality of individual symbols.

Abstract: A gaming device including a memory device, and a processor is disclosed. The processor may cause display of a plurality of symbols including at least one symbol displaying a respective credit value thereon during a base game. The processor may, in response to triggering a feature game, determine a plurality of persistent values based at least in part on the at least one respective value symbol displayed in the base game, and cause display of a plurality of credit meters displaying the plurality of persistent values. The processor may generate a continuous symbol sequence by randomly assigning a respective persistent value of the plurality of persistent values to a set of feature symbols included in the continuous symbol sequence, and cause display of the continuous symbol sequence during the feature game including causing display of the set of feature symbols.

The instructions cause the processor to display a plurality of game reels including a first game reel type having a plurality of symbol positions and a second game reel type including a grouped symbol position. The instructions also cause the processor to display a bonus symbol in the grouped system position and, in response to displaying the bonus symbol, to display an expanded display area comprising at least one additional symbol position located above the reels of the first game reel type. The instructions further cause the processor to determine a game outcome based upon a combination of the at least one additional symbol position and the plurality of symbol positions.
