    Bison Bonanza Game Overview

    The bet sizes available in Bison Bonanza range from 20p to £10.

    Betting in this game features a Scatter Pays mechanic.

    Cascading Symbols 

    A chain reaction takes place when you complete winning combinations in this game. Symbols involved in the wins will be removed from the reels, with new symbols dropping down to replace them. This can lead to a streak of wins from just a single spin.

    When a cascade fails to create a new winning combination, the process will end.

    Free Spins

    Trigger the Free Spins bonus round by landing at least four Bonus symbols on a spin.

    The Multiplier symbol is activated during this bonus, and when it is displayed along with a winning combination a multiplier worth 2x - 500x your wager is awarded.

    When you've completed your cascades, the values of all visible Multiplier symbols are added together, causing the total win from the cascades to be multiplied by the sum.

    You will play your free spins using the same bet size as the triggering spin.

    Land at least three Bonus symbols on a free spin to re-trigger the feature, giving you an extra five free spins.

    Your account is credited with the total winnings from the bonus at the end of Free Spins before regular play resumes.

    Free Spins Selection 

    You can choose from four different options when you enter the Free Spins bonus round:

    • 12 free spins with the Multiplier symbol ranging from 2x to 100x.
    • Eight free spins with the Multiplier symbol ranging from 4x to 200x.
    • Five free spins with the Multiplier symbol ranging from 8x to 500x.
    • Mystery Choice: The free spins and Multiplier range on offer is shuffled into six panels. You must pick one panel in each category, and the revealed values will be used during Free Spins.

    Return to Player 

    Return To Player (RTP): 95.50% - 95.51%. 

    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 between £95.50 - £95.51 of wins.
