Patent ID: 11210903

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.
