    Action Bank Slot Series

    Action Bank is back in this new addition to the fun-packed slot series. Featuring classic 7 and Bar symbols, this is a retro-themed slot offering exciting chances to break open the Free Spins vault. 

    O Symbols

    These symbols are essentially blocker symbols, since they can take up spaces on the reels without contributing to wins. 

    They can, however, transform into Vault symbols, which could send you to the Free Spins Bonus!

    Vault Symbols

    Find five Vault symbols across all the reels on a single spin to activate the bonus choice.

    Here, you can choose between playing the Free Spins Bonus or the Big Bank Bonus. 

    Let's take a look at the two options below!

    Free Spins Bonus

    Pick a vault door at the very start of the bonus to reveal the number of free spins you will receive (this can be 5, 10, 15, 20 or 25).

    Once you have revealed your free spins prize, you can choose to accept it or gamble for the chance to win more free spins.

    Choosing to gamble, though, could result in you losing all the free spins.

    Three 'double' symbols will be added to the first reel at the start of the bonus: Double 7, Double Bar and Double X.

    Match these symbols with their standard versions on reels two, three, four and five to double the line win.

    You can play the bonus again by finding five more Vault symbols across the reels on a single spin, so watch out!

    Big Bank Bonus

    Click on the vault doors to reveal sapphires, rubies and diamonds hiding behind them.

    The key here is to find three matching gems to receive a multiplier prize:

    Return to Player 

    Return To Player (RTP): 94.00%

    The expected return is the amount we pay out to players relative to the amount of wagering on the game. 

    For example, if we take £100 of wagers we will, on average, pay out £94.00 of wins.
