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 random events are caused to be displayed on the display and, if a predefined winning event results, the machine awards a prize. If the predefined result includes a trigger condition which results in an initial series of free games awarded to a player and, during the initial series of free games, another trigger condition arises, a subsequent series of free games, including a bonus feature, is awarded and implemented immediately during the existence of the initial series of free games. The bonus feature applicable to the subsequent series of free games is applied to the remaining games of the initial series of free games as well as to the games of the subsequent series of free games.
