Bonus features

Free Spins

Scattered vault symbol across 5 reels could initiate the free spins bonus.

The player will be prompted to open a vault door where they will be awarded 5, 10, 15, 20, or 25 free spins, with the chance of selecting the Big Bank Bonus.

The player is then given the chance to gamble or collect their free spins with the chance to increase the amount of free spins or lose them all.

During the Free Spins bonus there are 3 double symbols added to the first reel - these are double X, double bar and double 7. These will double the players line win if matched with the corresponding consecutive singular symbol on reels 2, 3, 4 and 5.

During the free spins execution, the “O” symbols continue to change to “Vault” symbols on a chance basis.

If 5 further “Vault” symbols are achieved then the free spins are re-triggered and the player is prompted to pick a “Vault” symbol again.

 Any additional free spins awarded may NOT be gambled. Instead they will be added directly to  the free spins remaining.


Big Bank Bonus

If the bonus is activated the player has the chance of selecting the Big Bank Bonus during the vault selection.

During the Big Bank Bonus game, the player must select vault doors until 3 of the same colour gems are selected (sapphire, Ruby or Diamond).
