Abstract: A gaming system including a processor and a memory storing instructions thereon which, when executed by the processor, cause the processor to: select symbols from reel strips stored in the memory for display in corresponding columns by determining stopping positions for the reel strips; cause display of the selected symbols in the columns on a display of a gaming device; determine that a trigger condition stored in the memory is satisfied based on the selected symbols; and in response to determining that the trigger condition is satisfied: replace one or more of the selected symbols in a group of symbol positions with an animation effect, the animation effect including display of a spin and stop sequence of credit values in the group of symbol positions; select a subset of the credit values; and cause display of the subset of credit values in the group of symbol positions.

Abstract: In one aspect, an electronic gaming system is provided. The electronic gaming system may cause to be displayed on a display device a game interface including a matrix having a plurality of symbol positions for displaying a symbol within each symbol position, generate, based on an RNG call outcome, an optimal game outcome, programmatically select a suboptimal game outcome based on the generated optimal game outcome, display at least a portion of the suboptimal game outcome in the matrix, cause to be displayed a prompt to select from a plurality of user options to modify at least one symbol of the at least a portion of the suboptimal game outcome displayed in the matrix, modify, based on a selection received from a user of one of the plurality of user options, the symbols displayed in the matrix, and determine if the optimal game outcome is displayed.

Abstract: An electronic gaming device that satisfies a return-to-player value when different features are initiated. The electronic gaming device includes a display device and a controller. The controller animates in the active reel matrix a plurality of game symbols, and a plurality of configurable symbols selected moving from a space moving into the active reel matrix. When the plurality of game symbols selected include a first trigger symbol, the controller also expands the active reel matrix to include more symbols. When the active reel matrix includes a second trigger symbol, the controller absorbs values of the plurality of configurable symbols into the second trigger symbol.
