Abstract
A gaming machine 10 has a display 12 and a game controller arranged to control images of symbols displayed on the display 12.

The game controller monitors and stores data relating to a number of free games awarded to a player during a playing session. The gaming machine 10 includes a selector for operation by the player so that the player can choose when, during the playing session, any free game is to be played.
