    Reef Raider Slot 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, featuring 15 meter bars in total. Whenever you remove a Clam Wild from play as a result of a cluster win, one meter bar is charged. 

    You can trigger features by charging these meter bars as follows:

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

    You are also able to fill the meter bars while playing the Free Spins bonus.

    Clam Wilds

    If you complete a winning cluster with a minimum of three medium win or low win symbols, a Clam Wild symbol is displayed in place of one of the removed medium-win or low-win symbols. This takes place prior to the Avalanche, improving your chance of winning with the new tumbling symbols.

    Anchor Drop

    This feature is triggered when you have three charged bars.

    You can activate Anchor Drop in the base game and Free Spins, and it causes between one and three different low win symbols to be selected at random, and these are erased from the play area.

    Random Wilds

    Complete six charged bars to unlock the Random Wilds feature.

    Between four and eight Wild Coin symbols are randomly placed on the reels when you play this feature.

    Mystery Chest

    Trigger the Mystery Chest feature by completing nine charged bars.

    When you activate this feature in the base game or in Free Spins, between two and 16 medium win and low win symbols are substituted for Mystery symbols.

    All Mystery symbols will then be revealed, allowing potential cluster wins to be evaluated.

    Cannon Blast

    To play the Cannon Blast feature, you require 12 charged bars award.

    A random symbol on the reels is taken out of the play area, in addition to every medium win and low win symbol in the same row and column as the selected symbol.

    It is not possible to remove Clam Wild symbols, Wild Coin symbols, and Multiplier symbols in this section.

    Free Spins

    Free Spins is triggered when you have a minimum of 15 charged Treasure Trail meter bars, with an extra two free spins awarded for every three additional charged bars you have.

    If you have 15 charged bars while playing the feature you receive an extra free spin, and another free spin is available if you have an additional three charged bars.

    When the Free Spins counter reaches zero, this bonus round concludes.

    Mystery Overlay

    The Mystery Overlay feature is activated when you enter Free Spins.

    Five Mystery symbols are shown 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.

    The Mystery symbols are then revealed, and a winning cluster of low win or medium win symbols is created.

    It's possible for extra Mystery symbols to be displayed on the reels randomly on each free spin.

    Should extra Mystery symbols appear horizontally or vertically adjacent to one of the positions of the initial cluster of Mystery symbols, the extra Mystery symbol position becomes a part of the cluster until the end of Free Spins.

    Winning Clusters

    If a symbol is horizontally or vertically adjacent to the same symbol, it forms part of a cluster.

    Multiple clusters of the same symbol that are not adjacent to each will be evaluated as separate clusters.

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

    You will only be paid for the highest win on every cluster. Simultaneous wins from numerous 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.
