Based on the combination of vaults activated, players can unlock a series of free games: nine for one vault, 12 for two vaults and 15 for unlocking all three.
In both the base game and free games, players can activate the multiplier (blue vault) for wild multipliers, while the bank (purple vault) awards increased credit prizes. During free games, the jackpot (red vault) feature allows players to win the mega, super, minor, or mini jackpots by collecting matching symbols. Four matching minor or mini symbols, or five matching mega or super symbols, will grant players their corresponding jackpot values.
Additional vault features can be activated during the free games, increasing the chances of unlocking even greater rewards.
