An interactive electronic reel gaming machine that includes a special region is disclosed. A game controller is configured to provide a reel with a particular arrangement of display positions, where each display position includes a separately controlled individual reel. Following receipt of a user input, one or more of the individual reels are spun and stopped, displaying symbols (e.g., corresponding to playing cards, pictures, credit values, etc.) in one or more of the display positions. The game controller is configured to apply a multiplier to symbols displayed in the special region. Pay awards are made when clusters of two or more like symbols are located in adjacent display positions. The pay award is increased if one or more symbols of the cluster is located in a display position corresponding to the special region. The symbol display positions are configured in a geometric shape.
