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: An electronic gaming device includes a memory for storing computer executable instructions and processor in communication with the memory. The instructions cause the processor to generate a first outcome of a game based on a first random number generator (“RNG”) output, the first outcome including a plurality of symbols positioned on a plurality of reels and determine that the first outcome does not include a winning symbol combination of a first symbol type. In response to the determination, the processor executes a reel boost mechanic enhancement including determining whether to modify the first outcome by adding symbol of the first symbol type to a first reel. The instructions further cause the processor to determine that the modified first outcome increases an award outcome of the game as compared to the first outcome and cause display of the modified outcome including the modified first reel with the added symbol.

Abstract: A gaming device may perform various electronic games, such as a keno game, and may include a game controller configured to control operations of the performed electronic games. During the course of a game performed on the gaming device, the game controller may control various winning scenarios, including alternate winning scenarios. At certain stages in a keno game, a number of markers may be selected. Before, after, or while these markers are selected, the game controller may determine how many bonus markers will be selected. Based on the number of selected bonus markers, the game controller may initiate a bonus draw phase where an additional number of markers may be selected. After all markers have been selected, any selected bonus markers may be added together and the calculated sum may be added to a credit balance associated with a player of the gaming device.

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 device is disclosed to (i) cause display of a game play matrix including a plurality of symbol positions including a set of active symbol positions and a set of locked symbol positions and arranged in columns and rows in response to triggering a bonus game; (ii) cause display of a modifier row proximate to the game play matrix where the modifier row; (iii) randomly determine a first set of symbols for displaying on the modifier row; (iv) randomly determine a second set of symbols for displaying within the active symbol positions of the game play matrix; and (v) cause modification of at least one modifiable symbol of the second set of symbols by showing a respective value assigned to a value symbol of the first set of symbols being transferred to the at least one modifiable symbol displayed within the game play matrix.

Abstract: Memory-efficient techniques for assigning credit values to credit symbols in games of chance are provided. Such techniques allow such credit values to be displayed in ascending or descending order while still allowing for control of the rate at which the credit values grow (or decrease) in value. Moreover, such techniques allow the particular sequences of credit values that are assigned to be dynamically generated from one game to the next, thereby avoiding potentially repetitive use of a limited number of pre-defined credit value sequences to assign credit values or the need for large numbers of pre-defined credit value sequences that may unnecessarily consume memory.

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.

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: An electronic gaming machine (EGM) includes a processor that provides opportunities to improve a winning combination in a base game window by copying the winning combination into one or more bonus game windows. The EGM achieves a designated game's Return to Player (RTP) while providing the opportunities. When a round of a game provided by the EGM generates an outcome in a base game window with a winning combination that includes one special symbol, the winning combination is copied to one or more bonus game windows. The bonus game windows are then played out to randomly determine whether to modify or improve the copied winning combination of the base game.

Abstract: An electronic gaming machine (EGM) includes a processor that achieves a designated RTP by providing a game feature that randomly awards one or more metamorphic feature types within a single spin. Additionally, the game feature that randomly awards one or more metamorphic feature types may be based on a triggering mechanism. The EGM utilizes different weight tables, reel strips, or a combination thereof depending on how the game triggers the game feature. For example, the game may trigger the game feature based on a base game outcome (e.g., 3SCAT, 4SCAT, and/or 5SCAT), a random feature trigger, the buying of an instant feature, or a combination thereof. Based on the triggering mechanism used, the game may have different probabilities in triggering one or more of the metamorphic feature types for a single spin.

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 combination of the at least one additional symbol position and the plurality of symbol positions.
