    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 substitute for all symbols bar Scatters in this game, helping to form wins.

    They can only appear in the symbol positions above reels two, three, four and five. 

    Only the highest win per winning combination pays out.

    TNT Symbols

    TNT symbols can land in any position.

    They reveal the same random symbol on the reels apart from Scatters. 

    Scatter Symbols

    Scatters can land on any reel except the positions above reels two to five. 

    Four Scatters appearing will award you 12 free spins - every Scatter that appears above four will award you an extra 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.

    During Free Spins, Free Spins Scatters can land in the positions above reels two to five.

    Three or more Free Spins Scatters appearing will award you even more spins:

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

    Bets in Free Spins use the same stake as the triggering bet. 

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

    Jackpot King Promotional Pot System

    During any spin there is a chance that the Jackpot King Bonus can be triggered by achieving 5 Jackpot King overlay symbols on reels 1 to 5.

    The Jackpot King Promotional Pot System is available on any stake on any game plugged into the Jackpot King Promotional Pot.

    Spin the reels to accumulate Crown symbols to move up the win ladder. 

    Achieve 15+ Crown symbols to enter the Wheel King section of the feature.

    After any spin choose an icon to reveal one of the following outcomes:

    Spin - spins the reels again, with any additional Crown symbols in view adding to the win ladder.

    Collect – ends the feature with you being awarded a Bonus Win based on the multiplier of your Total Bet reached on the win ladder.

    Wheel King - reveal this to go directly into the Wheel King round of the feature.

    Achieving 15+ Crown Symbols during the Jackpot King Bonus awards the Wheel King Bonus.

    The Wheel King Feature is a Tombola style Wheel consisting of Big Win Multiplier segments and Jackpot King Progressive pot segments.

    Spin the wheel to win either a Big Total Bet Multiplier or the Jackpot King Promotional Jackpot.

    NOTE - The Jackpot King Promotional Jackpot can only be won during the Wheel King part of the bonus.

    When the Promotional Pot is won, it is reset and begins to rise again.

    Simultaneous jackpot wins cannot occur. Should two players appear to win the jackpot at the same time the first player to trigger the jackpot will win the whole jackpot amount, the second player would win the reserve pot plus any further contributions made.

    In the event of a communication error after a promotional pot win result has been determined and before it has been displayed on screen, the win amount will automatically be transferred to the your account.

    While the game is live, the jackpot cannot be terminated. If the game is removed, the outstanding pool amount can be transferred to another jackpot.

    Malfunction voids all plays and pays throughout this game.

    Return to Player 

    Return to Player (RTP): 94.50% + 3% jackpot contribution. 

    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 £94.50 of wins, plus the chance to win the jackpot.
