Method and system are disclosed for allowing players at wagering game terminals to select entire sets of bonus games instead of a single bonus game upon occurrence of a certain randomly selected basic game outcome. One or more of the bonus games or sets of bonus games may be temporarily unavailable or “locked” to the player. The player may unlock the bonus games or sets of bonus games by acquiring certain game assets, reaching certain game milestones, and/or exceeding certain wagering levels. The unlocked games may reveal credits, prizes, progressives, basic and/or bonus game updates, or additional bonus games, some of which may also be locked. The updates and additions may already be present in the wagering game terminals or they may be downloaded from a central location. The player may retain the locked and unlocked statuses of the bonus games across multiple wagering game sessions and/or wagering game terminals.
