    Action Bank Wonder 500 Slot Game Overview

    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

    O symbols are blockers, and they can land on the reels without helping to form new winning combinations.

    It is possible for these symbols to turn into Vault symbols, and this could unlock the Free Spins Bonus.

    Vault Symbols

    Hit five Vault symbols on a spin to initiate the bonus choice. You will then be able to select whether to enter the Free Spins Bonus or the Big Bank Bonus.

    Free Spins Bonus

    Choose a vault door when you begin this bonus round, and the amount of free spins you will receive will be determined.

    Possible allocations of free spins are five, 10, 15, 20 or 25.

    As soon as the number of free spins you will receive has been shown, you can either collect them and play the bonus, or gamble them for the opportunity to trigger extra free spins.

    If you decide to gamble and lose, you could forfeit all of the free spins you were awarded.

    Before your first free spin is played, three 'double' symbols are placed on reel 1: Double 7, Double Bar and Double X.

    You can double the value of any payline win by matching one of the double symbols with their regular versions on reels 2-5.

    Land five Vault symbols on the reels on one of your free spins to re-trigger the bonus round.

    Big Bank Bonus

    In the Big Bank Bonus, you must select the vault doors. This will reveal sapphires, rubies and diamonds that are hidden behind them.

    Once you have revealed three identical gems, a multiplier will be triggered:
