A method of game play, where a plurality of graphic objects are displayed on the display (106), each graphic object being operable to present one or more symbols. A subset of the graphic objects (604, 606, 608, 610) are activated to present symbols on the display, and at least one remaining graphic object (602) is obscured during the activation. The remaining graphic object (602) is revealed if a combination of symbols presented on the activated subset matches an eligibility criterion, and the revealed graphic object (602) is activated to present one or more symbols. An award is awarded if the symbols displayed on the graphic objects match a specified winning criterion.
