Collect enough bonus points to unlock the Bonus Game — choose your vault challenge and go for bigger prizes.

All wins are expressed as a multiplier of your play amount. The table below lists every possible outcome.

Key Vault bonus outcomes (multiplier of total bonus cost):

Return to Player (RTP): This game has a theoretical RTP of 96%. Actual results may vary over short sessions.

Volatility: Medium-high. Wins are less frequent but tend to be larger when they hit.

Minimum play amount: Determined by the available ladder. Start small to extend your session.

Maximum win: 500× your play amount per round.

Malfunction voids all pays and plays. In the event of a disconnection during a round, the result is preserved and will be shown on reconnection.

Bonus Game is triggered by accumulating bonus progress. The Key Vault bonus requires collected keys and has its own paytable.

Play responsibly. If it stops being fun, take a break. Set limits and enjoy the game.
