    All reels can reveal up to seven symbols. 

    Wins are awarded for matching consecutive symbols (regardless of height) from left to right, starting with the left-most reel.

    All wins are added together and multiplied by the stake.

    Wild Symbols

    Wilds can only land in the symbol positions above reels two to five in this game. 

    They override all symbols except Scatters, to help form wins. 

    Only the highest win per winning combination pays out.

    TNT Symbols

    This symbol can appear in any position.

    Whenever one lands, it will reveal the same random symbol on the reels.

    The TNT symbol cannot reveal Scatters. 

    Scatter Symbols

    Scatters may land on any reel apart from the positions above reels two, three, four and five. 

    Four Scatters appearing will award you 12 free spins. 

    Every extra Scatter above four will award you another five free spins. 

    Scatter wins are awarded in addition to reel wins.

    Free Spins

    An unlimited win multiplier is active during Free Spins - it starts at one and increases by one with each Cascade.

    Free Spins Scatter symbols can land in the positions above reels two to five in this round.

    Land three or more Free Spins Scatters to win extra spins:

    • Three Free Spins Scatters = another five free spins
    • Four Free Spins Scatters = another 10 free spins

    Bets in Free Spins are the same as the triggering bet. 

    Any wins will be awarded at the end of the round before regular play resumes.
