    The bet sizes available in Action Bank Wonder 500 range from 10p to £2.

    Betting in this game is fixed at 20 paylines.

    O Symbols

    When O symbols appear, they can block new wins being created.

    However, O symbols can also transform into Vault symbols, which may enable you to activate the bonus choice.

    Vault Symbols

    When five Vault symbols appear on any spin, the bonus choice will be activated. Make your choice between either the Free Spins Bonus or the Big Bank Bonus.

    Free Spins Bonus

    If you opt to play the Free Spins Bonus, you will first select a vault door. This will allocate you a number of free spins, which could be any of the following: five, 10, 15, 20 or 25.

    You can either collect these free spins or gamble them, which could increase your allocation.

    If you have a losing gamble, it may forfeit each of the free spins that you had received initially.

    You can find three 'double' symbols on reel 1 when you spin the reels in this bonus round: Double 7, Double Bar and Double X.

    If one of the double symbols appears alongside its standard version on reels 2-5, the payout of your winning combination can be doubled.

    The Free Spins Bonus can be re-triggered if five Vault symbols are displayed on the reels.

    Big Bank Bonus

    When you play this bonus round, you must choose from the vault doors shown on your screen to reveal hidden sapphires, rubies and diamonds.

    As soon as three matching gems have been revealed, the corresponding multiplier value below will be awarded:
