Abstract: An electronic gaming system including a memory and a processor is described. The processor is configured to cause display of an adjustable game play matrix including a plurality of reels. A first column of the adjustable game play matrix includes a first predefined number of reels. The processor is also configured to randomly determine a first number of symbols to display on the first column for a first instance of an electronic game, randomly determine a first plurality of symbols corresponding to the first number of symbols, and select a first size, of a plurality of sizes, for each symbol of the first plurality of symbols to generate a sized first plurality of symbols. The processor is also configured to adjust display of the reels on the first column and cause display of the sized first plurality of symbols at a first number of the first predefined number of reels.

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.

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: An electronic gaming system is provided. The electronic gaming system may be configured to: (1) in response to a bonus feature being triggered, generate a game interface including a plurality of matrix positions; (2) in response to the bonus feature being triggered, record each of the matrix positions as being in an active state; (3) for each matrix position recorded as being in the active state, perform a first random determination; (4) cause a cash on reel (COR) symbol to be displayed in at least one of the matrix positions based on the first random determination; and (5) record each matrix position in which a COR symbol is not displayed following the first random determination as being in an inactive state.

Abstract: A system for displaying visual effects corresponding to events that occur in connection with bonus features of electronic wagering games may include and/or implement a display device and/or circuitry. In one example, the circuitry may be configured to detect a first event that triggers a bonus feature of an electronic wagering game and to detect, during implementation of the bonus feature, a second event that triggers a first collection of one or more values represented by one or more symbols on one or more reels of the electronic wagering game. In this example, the circuitry may also be configured to perform, upon completion of the bonus feature, a second collection of the values represented by the symbols and to then direct the display device to render one or more visual effects corresponding to the first event and the second event. Various other systems and methods are also disclosed.

Abstract: An electronic gaming device that includes a memory and a processor is described. The processor is configured to, for a first play of an electronic game, cause a first qualifier symbol to be displayed on a first reel, cause one or more first output symbols to be displayed, and cause one or more first output amounts to be added to the first qualifier symbol. The processor is also configured to, for a second play of the electronic game, cause a second qualifier symbol to be displayed on a second reel while the first qualifier symbol remains displayed, cause one or more second output symbols to be displayed, and cause one or more second output amounts associated with the one or more second output symbols to be added to the first qualifier symbol and the second qualifier symbol.
