Gaming Machine and Method

A gaming machine comprising:

• a display for displaying a game, wherein said game comprises randomly selected game symbols displayed in an array of game positions and where predetermined winning combinations of said randomly selected game symbols in said game award prizes to a player;
• a game controller for controlling the display of said game symbols on said display;
• and
• a value transfer mechanism for receiving value from said player, wherein said game controller communicates with said value transfer mechanism such that when a threshold amount of value has been received from said value transfer mechanism, said game controller initiates a play of said game;
• wherein said game controller configures said array so that said array comprises at least one non-game symbol position in which only a non-game symbol can be displayed, said non-game symbol being a symbol that does not form part of any of said predetermined winning combinations;
• and
• wherein the display of said non-game symbol and at least one of said predetermined winning combinations in a first play of said game causes said game controller to enhance the prize awarded for said at least one predetermined winning combination.
