Abstract: A method, apparatus, and computer readable storage to implement a bonus trigger mechanism which determined when a free bonus game (or multiple free games) is awarded to the player. A random determination determines whether the game initially qualifies for the bonus round. The qualifying can be displayed in numerous ways, such as adding tags (indicia) to symbols which are used for game-play. In order that the player actually receive the free bonus round(s) the player also has to win the underlying game.
