    Rich Wilde and the Tome of Madness Game Overview

    The bet sizes available in this game range from 10p to £20.  

    This game employs the cluster pays slot mechanism, meaning there are no paylines.

    Game Rules

    Symbols horizontally or vertically adjacent to each other form clusters.

    Clusters made up of the same symbol but not adjacent to each other will pay out as separate clusters.

    Eye Marks

    Eye Marks can appear on the reels at random.

    Completing a win in an Eye Mark location will open the eye, adding two special Wild symbols to the reels once win evaluations are finished.

    With each win, the Portal will be charged.

    Special Wild Symbols

    Special Wilds can be awarded by completing wins on a particular number of symbols:

    Number of Winning Symbols
    Special Wilds Awarded


    • The Abyss Portal Effect will trigger if a special Wild is involved in a win on seven or 14 symbols.
    • The Void Portal Effect will trigger if a special Wild is involved in a win on 27 symbols. 
    • The Other World free round will activated if a special Wild is involved in a win on 42 symbols. 

    After effects have been played, the game will return to normal.

    Portal Effects

    • Abyss - All symbols in the row or column containing the winning special Wild will be removed. This charges the Portal further. If a special Wild is removed during the effect, all symbols in that row or column will also be removed
    • Void - All instances of a randomly chosen symbol will be removed from the grid.


    Other World

    The Other World round will trigger automatically after winning on 42 symbols. 

    One free round is awarded with three random Portal Effects. 

    If the Portal becomes over-charged, an extra Portal Effect will trigger whenever you collect three more winning symbols. 

    When a special Wild is involved in a win, or when no more wins are possible, another Portal Effect will be triggered.

    Up to seven Portal Effects can be triggered in total.

    Both the Abyss and Void Portal Effects are available during the Other World feature.

    11 or 12 Eye Marks will be visible during the round - if all eyes are opened, one Mega Wild Cthulhu symbol will be added to the reels.

    With each cascade, Cthulhu symbols move down a position.

    The Cascade will keep going until no more wins land. 

    Return to Player 

    Return to Player (RTP): 94.52%.

    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 £94.52 of wins.
