Abstract: A gaming system includes a processor that initiates a base game including a matrix having a plurality of symbol positions. The processor causes display of an array of symbols populated in the symbol positions. Each symbol in the array of symbols is randomly selected from a reel strip. A first reel strip associated with a first symbol position includes a first special symbol and a second reel strip associated with a second symbol position includes a second special symbol. A feature game trigger condition is satisfied in response to at least one of: i) the first special symbol being displayed in the first symbol position and ii) the second special symbol being displayed in the second symbol position. The first special symbol is a trigger for a first feature game and the second special symbol is a trigger for a second feature game.

Abstract: A gaming system includes a processor and a memory storing a plurality of stage game rule sets. Each rule set of the stage game rule sets corresponding with a stage of a game. The processor is programmed to cause display of columns each including symbol positions based on a first game configuration for a first instance of a first stage of the game and determine a first game outcome for the first instance based on the first game configuration and a first rule set. The processor is further programmed to change the first game configuration to a second game configuration based on a first trigger symbol occurring in the first game outcome and determine a second game outcome for a first game instance of a second stage of the game based on the second game configuration and a second rule set associated with the second stage.

The at least one processor may be configured to, in response to a bonus game being triggered, cause a display device to prompt selection of an upgrade type of a plurality of upgrade types, receive a selection of a first upgrade type of the plurality of upgrade types, randomly determine a first upgrade based on the first upgrade type, determine a first state based on the first upgrade type or the first upgrade, select a first set of reel strips of the plurality of sets of reel strips based on the first state, and generate and display in a game matrix a first game outcome based on the first set of reel strips and the first upgrade.

Abstract: An electronic gaming system including a memory and a processor is described. The processor is configured to cause a persistent feature to be provided as being associated with an electronic game and a player account. The processor is also configured to, as play of the electronic game by the player account progresses, cause a meter associated with the persistent feature to fill, wherein as the meter fills, return to player (RTP) of the electronic game increases, and wherein the meter is caused to be filled based upon a bonus symbol being provided during play of the electronic game. The processor is further configured to, after a predetermined amount of time passes where no plays of the electronic game by the player account occur, cause the meter associated with the persistent feature to empty, wherein as the meter empties, RTP of the electronic game decreases.

Abstract: An electronic gaming machine includes one or more processors and memory storing instructions that, when executed, cause the processors to perform operations. The operations include presenting a feature game comprising metamorphic feature game interface elements, each corresponding to a different feature game value. During the feature game, a feature game value is adjusted based on an output of a random number generator, and an appearance of a corresponding metamorphic interface element is adjusted. An outcome of the feature game is determined based on an additional output of the random number generator and the feature game values. A state of a base game is adjusted based on the outcome of the feature game. The feature game values may be incremented according to a sequence of levels, each corresponding to a different enhancement multiplier. The outcome may be determined using a Hold and Spin matrix with activated metamorphic enhancements applied to positions.

Abstract: An electronic gaming machine includes a game controller configured to (a) determine, during a base game, that a feature game trigger condition is satisfied; (b) activate a feature game within the base game; (c) display, a feature game play area associated with the feature game, the feature game play area including a plurality of zone patterns overlaid on the symbol display positions; (d) convert the symbol display positions into independent feature game reels; (e) generate a first game outcome by (i) holding a first set of feature game reels displaying the prize symbols while (ii) selecting and displaying a symbol for a second set of feature game reels; (f) determine that at least one zone pattern is complete with prize symbols; (g) apply a zone multiplier associated with the zone pattern to credit values within the zone pattern; and (h) award the incremented credit values to the player.

Abstract: Electronic gaming machines and systems are disclosed that provide for a symbol-based main game that features an array of symbol positions that may, if an array growth condition is met, increase in size. Determining whether the array growth condition is met may involve determining how many array growth symbols are shown in association with a game play. A further determination may be made as to whether a feature game trigger condition is met and, if so, a feature game may be presented that utilizes the same array of symbol positions that were present in the main game when the feature game was triggered. Additional array growth may occur in the feature game if the array growth condition is met again.

Abstract: An electronic gaming system includes a memory device and a processor configured to cause display of a plurality of symbol positions arranged in a game matrix with a first set of symbols including a first designated persistence symbol displayed in a first symbol position of a first column and a second designated persistence symbol displayed in a first symbol position of a second column. In response to the first designated persistence symbol being displayed in the first column, the first designated persistence symbol is locked in the first symbol position of the first column for subsequent spins of the bonus game. In response to the second designated persistence symbol being displayed in the second column, the second designated persistence symbol is moved horizontally from the second column to an adjacent column of the plurality of columns for a second spin of the bonus game.

Abstract: A gaming system includes a processor and a memory storing instructions and a persistence counter. The instructions cause the processor to cause display of an initial game outcome by displaying symbols from a plurality of reels in a plurality of columns, the plurality of reels including a plurality of symbol types and increment the persistence counter based on the initial game outcome. The instructions further cause the processor to determine, based on a value of the persistence counter, at least one symbol type of the plurality of symbol types, change the at least one symbol type in the initial game outcome to a second symbol type, and determine, based on changing the at least one symbol type, an upgraded game outcome.

Abstract: An electronic gaming system including a memory and a processor is described. The processor is configured to cause display of a first display area including a plurality of symbol positions for an electronic game, determine a respective symbol for each symbol position of the plurality of symbol positions, and cause at least one bonus symbol to advance at least one symbol position of the plurality of symbol positions toward an edge of the plurality of symbol positions. The processor is also configured to cause display of at least a portion of the at least one bonus symbol in a second display area wherein display of at least the portion of the at least one bonus symbol indicates that an output amount will be provided and cause the output amount associated with the at least one bonus symbol to be provided.
