    Reef Raider Online Slot Game

    You can play Reef Raider from just 20p per spin.

    This game uses the Cluster Pays mechanic.


    The Treasure Trail

    There are 15 meter bars around the reels, which form the Treasure Trail.

    One meter bar is charged every time a Clam Wild symbol is removed as a result of a cluster win.

    Reaching a certain number of charged meter bars will trigger different features:

    Number of Charged Bars
    Feature Unlocked
    3Anchor Drop
    6Random Wilds
    9Mystery Chest
    12Cannon Blast
    15Free Spins

    It is possible to charge meter bars during the Free Spins Bonus.


    Clam Wild Symbols

    A Clam Wild symbol will appear if a winning cluster is achieved with at least three medium-value or low-value symbols.

    When this happens, the Clam Wild symbol replaces one of the symbols involved before the Avalanche begins.


    Anchor Drop Feature

    When the Anchor Drop feature is activated, between one and three different low-value symbols are randomly selected.

    All corresponding symbols are then removed from the reels.


    Random Wilds Feature

    When the Random Wilds feature is activated, between four and eight Wild Coin symbols are randomly added.


    Mystery Chest Feature

    When the Mystery Chest feature is activated, Mystery symbols will replace between two and 16 medium-win and low-win symbols.

    All Mystery symbols are then revealed and any potential cluster wins evaluated.


    Cannon Blast Feature

    When the Cannon Blast feature is activated, a random symbol on the reels is removed.

    All medium-win and low-win symbols that are in the same row and column as the chosen symbol are also removed.

    It is not possible for Clam Wild symbols, Wild Coin symbols and Multiplier Wild symbols to be removed during this feature.


    Free Spins Bonus

    The Free Spins Bonus is triggered when 15 or more meter bars are charged.

    Triggering the bonus with 18 charged bars will award an additional two free spins.

    Charging 15 bars during the bonus will award one extra free spin.

    You will receive an extra free spin every time three bars are charged during the bonus.

    The bonus ends when the free spins counter reaches zero.


    Mystery Overlay Feature

    This feature is activated when the Free Spins Bonus is triggered.

    Five Mystery symbols are placed on the reels - one is placed in the centre and four more are placed on the positions horizontally and vertically next to the centre.

    All Mystery symbols are then revealed to form a winning cluster of low-value or medium-value symbols.

    Extra Mystery symbols may randomly appear on each free spin.

    If the additional Mystery symbols are horizontally or vertically adjacent to the original cluster, then they will become a part of the cluster for the rest of the Free Spins Bonus.


    Winning Clusters

    Clusters are formed of matching symbols that are directly adjacent to each other.

    Multiple clusters of identical symbols will pay separately if they are not adjacent to each other.

    Cluster wins are equal to the value shown in the Paytable multiplied by any multipliers if applicable.

    Only the highest win is paid per cluster.

    Wins achieved from multiple clusters at the same time are added together.


    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.
