Cluster Tumble

Cluster Tumble is the bubbly slot game featuring the cluster pays mechanic, as well as Wilds, Scatters and special Stone Blocks. 

    Cluster Tumble Slot - How to Play

    This is a cluster pays slot machine, which means that there are no paylines.

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

    Multiple clusters of the same symbol that are not adjacent to each other are paid out as separate clusters. 

    Wild Symbols

    Wilds replace certain symbols in this game to help create wins.

    Scatter Symbols

    Scatter symbols may appear throughout your game.

    Land at least three to activate the Free Spins feature - more information about this is below.

    Stone Blocks

    In Cluster Tumble, there are two types of Stone Blocks: 

    1. Normal stone blocks 
    2. Special stone blocks

    Achieving an adjacent win will activate a special stone block.

    Each time a special stone block becomes activated, it will trigger the respective feature.

    Special stone block features are outlined in the table below:

    Special Stone Block Features
    Lightning WinThe special stone block will be replaced by a random Target symbol. When it is applied after the following cascade, all normal symbols that match the Target symbol, including Wilds, will form a win, regardless of their board position
    WildWilds override all normal symbols
    Fire TransformThe special stone block will be replaced by a random Target symbol. On the next cascade, up to two symbols will turn into the same symbol as the Target symbol

    Free Spins

    There are two ways to activate the Free Spins feature:

    • When three Scatters hit the the reels 
    • By removing all stone blocks from the board in the main game

    You will receive five initial spins each time Free Spins triggers. 

    Each time a Scatter lands during the round, you will be awarded one extra spin.

    Clearing the whole board will also award you three extra spins, as well as an increased multiplier. 

    The multiplier increases by three each time you clear the board (i.e. the first removal awards a x3 multiplier, the second awards a 6x multiplier, the third awards a x9 multiplier and so on). 

    As soon as the multiplier increases, the new value will be applied and remain for the rest of the round.


    Cluster Tumble RTP

    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 £96.40 of wins.
