    Clam Wild Symbols

    Forming a winning cluster with three or more medium-win/low-win symbols will create a Clam Wild symbol on the reels.

    The new Clam Wild symbol will replace one of the winning symbols before the Avalanche begins.

    Anchor Drop Feature

    One to three low-win symbols are chosen at random when this feature is triggered.

    All matching symbols are then taken off the reels.

    Random Wilds Feature

    Four to eight Wild Coin symbols are placed on random positions on the reels during this feature.

    Mystery Chest Feature

    Two to 16 symbols are replaced with Mystery symbols during this feature.

    The chosen symbols are either medium-win or low-win symbols.

    Once the Mystery symbols are added, they will reveal their hidden symbols and any potential wins are calculated accordingly.

    Cannon Blast Feature

    A symbol is randomly chosen to be removed from the reels in this feature.

    All medium-win/low-win symbols that are in the same row and column are then removed.

    Note: Clam Wild symbols, Wild Coin symbols and Multiplier Wild symbols cannot be removed as a result of the Cannon Blast feature.

    Free Spins Bonus

    Charging at least 15 meter bars on the Treasure Trail will activate the Free Spins Bonus.

    Two extra free spins are awarded for every three extra bars used to activate the Free Spins Bonus.

    It is possible to re-trigger the Free Spins Bonus by charging 15 bars during the bonus - this will award one more free spin.

    An additional free spin will be awarded for every three extra bars charged during the free spins.

    The Free Spins Bonus ends when there are no more free spins left.


    Mystery Overlay Feature

    During the Free Spins Bonus, the Mystery Overlay feature will trigger and add five Mystery symbols to the reels.

    One Mystery symbol will be added to the centre of the reels, while the other four will be added to positions that are directly adjacent (either horizontally or vertically).

    Once all Mystery symbols have been added, they will all reveal a cluster or low-win/medium-win symbols.

    It is possible for more Mystery symbols to randomly land on each free spin.

    New Mystery symbols may become part of the initial cluster if they are directly adjacent to it.

    Winning Clusters

    If clusters are not directly adjacent to each other, then they will pay separately even if they use identical symbols.

    Wins from clusters that are created simultaneously are added together.

    Only the highest win is paid on each cluster.


    Return to Player

    Return to Player (RTP): 96.10%

    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 £96.10 of wins.
