    Reef Raider Game Overview

    The bet sizes available in Reef Raider range from 20p to £20.

    This game does not feature paylines, instead using a Cluster Pays mechanic.


    Treasure Trail

    The Treasure Trail surrounds the reels, and consists of 15 meter bars. On each occasion that a cluster win causes a Clam Wild to be erased from play, you will have a single meter charged.

    Unlock features in this game by charging meter bars, as outlined below:

    • Three bars activates the Anchor Drop feature
    • Six bars activates the Random Wilds feature
    • Nine bars activates the Mystery Chest feature
    • 12 bars activates the Cannon Blast feature
    • 15 bars activates Free Spins

    During the Free Spins bonus, you are able to fill the meter bars.


    Clam Wilds

    If you secure a cluster win with three or more medium win or low win symbols, a Clam Wild symbol will substitute in for one of the removed symbols before the Avalanche occurs. This improves your chances of completing a win when the new symbols fall into place.


    Anchor Drop

    To unlock this feature, you require three charged bars.

    Activating Anchor Drop in the base game or Free Spins results in one to three alternate low win symbols being picked, with any identical symbols being deleted from the play area.


    Random Wilds

    You can play the Random Wilds feature when you have six charged bars.

    Between four and eight Wild Coin symbols are added to the reels in random positions.


    Mystery Chest

    Trigger this feature with nine charged bars, causing between two and 16 medium win and low win symbols to be replaced by Mystery symbols.

    All Mystery symbols are revealed before possible cluster wins are evaluated.


    Cannon Blast

    The Cannon Blast feature is playable once you have 12 charged bars.

    A random symbol on the reels is removed from the play area when you initiate this feature, as well as all of the medium win and low win symbols in the same row and column as symbol that was picked.

    In this feature, you cannot remove Clam Wild symbols, Wild Coin symbols, and Multiplier symbols.


    Free Spins

    When playing the base game, Free Spins is activated when you have at least 15 charged Treasure Trail meter bars. An additional two free spins is awarded for every three extra charged bars over the minimum required.

    In Free Spins, 15 charged bars unlocks an extra free spin, and every extra three charged bars triggers one further free spin.

    This bonus ends when you the Free Spins counter hits zero.


    Mystery Overlay

    Upon entering Free Spins, the Mystery Overlay feature is triggered. A total of five Mystery symbols land on the reels: one in the centre of the play area, as well as an extra four on the positions horizontally and vertically adjacent to the centre.

    Onc the Mystery symbols are unveiled, a winning cluster of low win or medium win symbols is formed.

    On each free spin, more Mystery symbols can appear on the reels at random.

    If any of the extra Mystery symbols land horizontally or vertically adjacent to one of the positions of the first cluster of Mystery symbols, the extra Mystery symbol position is included in the cluster until Free Spins ends.


    Winning Clusters

    A symbol is part of a cluster if it is horizontally or vertically adjacent to the same symbol.

    If you have multiple clusters of the same symbol, they will pay as separate clusters if they are not adjacent to each other.

    A cluster win is equal to the value shown in the paytable multiplied by any applicable multipliers.

    Only the highest win per cluster is paid. Simultaneous wins from multiple clusters are added.


    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.
