Skeleton Key

Don't be afraid to enjoy a game of Skeleton Key... there's lots to be won in this exciting slot!

    Skeleton Key Game Overview

    The bet sizes available in Skeleton Key range from 10p to £30.

    There are up to 7,776 paylines available in this game. 


    Reel Expansion 

    The initial reel window is three symbol positions high. 

    Reel Expansion is triggered when a Key Scatter symbol lands - it causes that reel to expand to six symbol positions high.

    The Key symbol will then disappear from the reels before empty positions are filled with new symbols from above. 

    Symbols continue to fall until there are no more Keys present. 

    All symbols can fall from above except the Key - only one Key symbol can land per reel, per spin. 

    Wins are calculated when all symbols have stopped falling.

    The reel window remains six symbol positions high for the following spin.

    It will decrease one position in height with each subsequent spin until it returns to three symbol positions high.

    Should a Key symbol land, that reel will expand to six symbol positions high again and the sequence resets. 

    Reel heights in the base game are saved separately for each bet level and remain between play sessions. 


    Wild Symbol

    Wilds can only land on reels two, three, four and five in the main game and Free Spins. 

    Mystery Symbol 

    Mystery symbols can transform into any symbol except Key, Bonus or Wild symbols.

    All Mystery symbols present will turn into the same symbol. 

    They can land on any spin.

    MultiWay Xtra Feature 

    If triggered, this feature guarantees between 243 and 7,776 paylines on every spin, based on the Reel Expansion feature.  

    You need to land matching symbols in any position, in adjacent columns starting from the leftmost column, in order to win. 

    Your prize amount will be multiplied if more than one matching symbol appears in the same column.

    Wilds override every symbol except Key, Mystery and Bonus symbols during this bonus.  

    You'll be paid the highest-value MultiWay Xtra win only for each symbol, per spin.


    Free Spins Bonus 

    Free Spins is activated if three or more Bonus Scatters appear anywhere on the reels.

    The amount of free spins awarded depends on the number of Bonus Scatter symbols:

    Bonus SymbolsFree Spins Awarded

    Land at least two Bonus Scatters during Free Spins to re-trigger the feature.

    This can happen several times - until you win the maximum 200 free spins per bonus.

    The amount of spins you win depends on the number of Bonus symbols present:

    Bonus SymbolsFree Spins Awarded

    Free Spins starts with a three symbol position-high reel window - it works the same as the Reel Expansion feature does in the base game. 

    There's also an accumulating multiplier starting at 1x in Free Spins. 

    You'll win another 1x multiplier for each Key symbol that appears, which will be added to the accumulating multiplier.

    All symbols can fall from above, including the Key symbol, in this feature; Mystery symbols may turn into a Key symbol. 

    You'll win another 1x multiplier if more than one Key symbol appears on any reel during Free Spins. 

    Symbols will continue to fall onto the reels until there are no Keys present. 

    Free Spins ends when all spins have been used or you reach the maximum number of free spins (200). 

    Wins are calculated at the end of each free spin once reel expansions, falling symbols, Mystery symbol transformations or multiplier increases have taken place. 

    The accumulating multiplier value will be applied to all wins. 

    Return to Player

    Return to Player (RTP): 96.49%

    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 £96.49 of wins.
