RECORDING AND REPRODUCTION OF WAGERING GAME PLAY STEP EVENTS OCCURING IN MULTIPLE NESTED BONUS GAMES

A gaming system includes game-logic circuitry that primarily performs a casino wagering game. The casino wagering game includes gaming events (play steps) having outcomes that may trigger and perpetuate a multi-level bonus game. As the wagering game is performed, a game cycle data record is created containing game cycle data related to the outcome of the play steps. A predetermined number of the most recent game cycle data records are stored in non-volatile memory. Each game cycle data record includes a predetermined number of play step data records for the base-game, bonus-game-triggering, and bonus-game play steps, as performed in chronological order. When the predetermined number of play step data records is exceeded, the oldest non-triggering play step data record is removed from the game cycle data and accrued into summary data specific to a nested-depth of the play step for the game cycle.
