    Skeleton Key Slot - How To Play

    Play with up to 7,776 paylines in Skeleton Key.

    The betting sizes available range from 10p to £20.

    Reel Expansion 

    When a Key Scatter appears on any reel you will enable the Reel Expansion feature, and that reel will expand from three symbol positions high to six.

    The Key symbol will be removed from the reels after the have expanded, and new symbols drop down from above to fill the vacant space.

    Key symbols cannot drop down from above the reels.

    Symbols will continue to drop into vacant reel spaces until no Key symbols remain. 

    On each reel on a single spin, no more than one Key symbol can appear.

    Once the reels have expanded and symbols are no longer dropping, wins will be evaluated.

    After the next spin, the reel window will decrease one position per spin until it is back to three symbol positions high.

    If a Key symbol lands on any spins that follow, the reel will once again expand to six symbol positions high, and the sequence will reset.

    Reel heights in the base game are separately saved for every bet level, and they are stored between play sessions.

    Wild Symbol

    In the base game and in the Free Spins Bonus, reels 2-5 are the only places where Wild symbols can be displayed.

    Mystery Symbol 

    Mystery symbols can land on any spin, and they can transform into any symbol with the exception of Key, Bonus or Wild symbols. 

    All Mystery symbols on the reels turn into the same symbol type.

    MultiWay Xtra Feature 

    When this feature is active, you will have between 243 and 7,776 ways to win on each spin, and this is based on the Reel Expansion feature.

    Starting with the column furthest to the left, you are paid when you match symbols in any position in adjacent columns.

    Your payout is multiplied if at least two matching symbols appear in a single column.

    During MultiWay Xtra, Wild symbols can override all symbols with the exception of Key, Mystery and Bonus symbols. 

    On each spin, you are only paid for the highest-value MultiWay Xtra win for each symbol.

    Free Spins Bonus 

    Trigger the Free Spins Bonus when three or more Bonus Scatters are displayed on the reels.

    You will receive a larger amount of free spins if more Bonus Scatters land:

    Bonus Symbols
    Free Spins Triggered

    If at least two more Bonus Scatters appear on a free spin, you will re-trigger this bonus round. The maximum number of free spins per bonus is 200.

    The number of spins awarded is based on the number of Bonus symbols that landed:

    Bonus Symbols
    Extra Free Spins Triggered

    A three symbol position-high reel window is active at the start of this bonus, and works in the same manner as the Reel Expansion feature. 

    In the Free Spins Bonus a win multiplier is active that begins at 1x, and increases by 1 whenever a Key symbol appears.

    During this bonus all symbols can fall down from above, while Mystery symbols are able to turn into Key symbols.

    Symbols continue to fall and vacant positions are filled until no Key symbols are visible.

    When you've used your free spins allocation, or you've unlocked the maximum number of free spins, the feature concludes.

    Wins are evaluated at the end of every free spin when all features have occurred.

    The accumulating multiplier value takes effect on all wins in this bonus.
