Abstract
A gaming machine has a display and a game controller arranged to control images displayed on the display. The game controller is arranged to play a game wherein a random event is caused to be displayed on the display. If a predefined winning event results, the machine awards a prize. When a secondary game, following a base game, is completed, a special symbol appears at at least one symbol position of the secondary game. The special symbol replaces, at least temporarily, an underlying symbol at the symbol position to contribute, if applicable, to a prize winning event.
