The present invention relates to a gaming system and to a method of gaming. A game is played by displaying a representation of selection of a plurality of symbols from a set of symbols. The game enables selection of at least one additional symbol in addition to those originally selected, to increase the number of symbol combinations available for assessing a game outcome. In an example, the additional symbol is displayed as being mounted on a substrate which is “flipped” to reveal the additional symbol. Another face of this substrate mounts the originally selected symbol. A plurality of additional symbols may be available for selection.
