Abstract
A gaming machine having a display and game control, the game control being arranged to play a game wherein a plurality of symbols are randomly selected from a predetermined set of symbols and displayed in rows on the display and if a winning combination of symbols results, the machine pays a prize. In a first aspect, a triggering event invokes a game feature in which a sprite randomly designates one or more of the symbols displayed on the display to be treated as special symbols for that particular game and a prize is awarded for any winning combinations formed with one or more of the special symbols. Embodiments of the special symbol include a wild card symbol and a scatter symbol. In a second aspect, the sprite designates the win meter or the credit meter, causing the amounts shown on the win meter and credit meter to increase.
