Abstract: A gaming machine includes a game controller that initiates play of a base game in response to a first input received via a player interface. In response to initiating the play of the base game, the game controller selects and displays first symbols at base game display positions displayed on a display device, and determines that a feature game has been triggered in response to a trigger condition. For each game of the feature game, the game controller selects and displays replacement symbols for display at feature game display positions not containing configurable symbols. In response to the feature game display positions displaying a first predetermined quantity of configurable symbols, the game controller expands the feature game display positions to include one or more additional feature game display positions.

Abstract: A gaming machine includes a game controller that initiates play of a base game in response to a first input received via a player interface. The game controller spins base game virtual reels to select and display a first symbols at display positions on a display device. The game controller, in response determining that a quantity of configurable symbols in the first symbols has a predetermined relationship to a predetermined quantity, triggers display of a feature game. The game controller further sets a quantity of remaining games for the feature game to an initial quantity. For each remaining game of the feature game, the game controller spins one or more feature game virtual reels to select and display symbols for one or more of the display positions with non-configurable symbols while holding configurable symbols at their respective display positions.

Abstract: A gaming machine includes a game controller executing instructions stored in a memory. The game controller establishes a credit balance in response to a credit input mechanism receiving a physical item with an associate credit value, and initiates play of a base game in response to a first input received via a player interface. During play of the base game, the game controller spins first reels to select and display first symbols at first display positions displayed on one or more display devices, and determine that a feature game has been won in response to a trigger condition. During play of the feature game, the game controller spins second reels to select and display a second symbols at second display positions displayed on the one or more display devices, and re-spins a subset of the second reels to select replacement symbols for at least a subset of display positions of the second display positions with non-configurable symbols while retaining configurable symbols at their respective display positions.

Abstract: A gaming machine includes a game controller executing instructions stored in a memory. The game controller establishes a credit balance in response to a credit input mechanism receiving a physical item with an associated credit value, causes a display device to display a first jackpot value associated with a first jackpot, and initiates play of a game in response to a first input received via a player interface. In response to initiating play of the game, the game controller spins virtual reels to select and display first symbols at display positions on the display device, and determines that the first jackpot has been won if the first symbols include a first configurable symbol with a first jackpot indicia as its variable component. The game controller increases the credit balance per the first jackpot value after determining that the first jackpot has been won.

Abstract: A gaming machine includes a credit input mechanism, a credit payout mechanism, a display device, a player interface, and a game controller executing instructions stored in a memory. The game controller establishes a credit balance in response to the credit input mechanism receiving a physical item with an associated credit value and initiates play of a game in response to a first input received via the player interface. The game controller spins virtual reels to select and display a first symbols at display positions on the display device. The first symbols are selected from non-configurable symbols and configurable symbols. The game controller determines that a prize, associated with an icon that has been split into a plurality of portions, has been won if variable components of the configurable symbols in the first symbols include each portion of the plurality of portions for the icon associated with the prize.

Abstract: A gaming machine. A memory stores a first set of symbols including first, second, and third symbols, and a second set of replacement symbols. A symbol selector selects symbols from the set of symbols, displays the selected symbols, and selects a replacement symbol to replace a selected third symbol in response to the third symbol being selected. A value assigner randomly assigns a prize value to a selected first symbol. An outcome evaluator determines if the selected symbols include a defined number of first symbols, and triggers a feature game when a defined number of first symbols are selected. Until an end condition is met in the feature game, the symbol selector causes the display to retain a selected first symbol, remove a selected second symbol, and replace the removed second symbol with a symbol selected from the feature game set of symbols.

Abstract: A gaming machine comprises a symbol selector for selecting a plurality of symbols from a set of symbols for display during play of a base game, the set of symbols including a plurality of non-configurable symbols and a plurality of configurable symbols; a random number generator for generating random prize values; a value assigner for assigning a generated random prize value to each selected configurable symbol; and an outcome evaluator for monitoring play of the base game, wherein a feature game is triggered in response to a trigger event, the trigger event comprising a predefined number of the plurality of configurable symbols being selected by the symbol selector for display.

Abstract: A gaming machine comprises a display, a game player input means and a game controller arranged to control images displayed on the display. The game controller controls play of a game in which a winning game result causes a prize to be awarded to a game player. The game comprises an interactive sequence related to a tournament in which a representation of a first video-player, of one team is displayed. An action of the first video-player to be executed is selected by the game player via the game player input means and the game controller selects an action to be performed by another video player. Depending on an outcome resulting from the selected actions, an award is made to the game player.
