Abstract

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.
