Skeleton Key

Skeleton Key Online Slot Game

You can play Skeleton Key from just 10p per spin.

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

Reel Expansion Feature

A Key Scatter symbol landing on a reel will cause the reel to expand in height to six symbol positions.

Once the reel has expanded, the Key symbol will disappear and symbols will fall into empty reel positions from above.

Key symbols cannot fall from above.

More than one Key symbol can land, but only one may appear on each reel during one spin.

Symbols continue to fall from above until no more Key symbols appear.

Wins are evaluated after the reel has expanded and all symbols have finished falling.

The reel remains six symbol positions high on the next spin, however, it will decrease in height by one position on each subsequent spin until it returns to the original height of three symbol positions.

If a Key symbol lands during subsequent spins, the reel expands to six symbol positions high again and the process repeats.

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

Mystery Symbol Feature

Mystery symbols may land on any spin.

All Mystery symbols that land will transform into the same symbol, which can be anything except the Key, Bonus, or Wild symbol.

Wins are evaluated after all symbols have transformed.

MultiWay Xtra Feature

There are between 243 and 7,776 paylines available on every spin, based on the Reel Expansion feature.

Match symbols in any position across adjacent columns from left to right to achieve a MultiWay Xtra win.

The award will be multiplied if more than one symbol is matched in the same column.

Wild symbols substitute for all symbols except the Key, Mystery and Bonus symbols.

Only the highest paying MultiWay Xtra win for each symbol is paid per spin. 

Free Spins Bonus

Landing three or more Bonus Scatter symbols anywhere will trigger the Free Spins Bonus.

The number of free spins awarded depends on how many Bonus symbols trigger the bonus.

• Three Bonus symbols - 10 free spins 
• Four Bonus symbols - 20 free spins
• Five Bonus symbols - 30 free spins

It is possible to re-trigger the Free Spins Bonus by landing two or more Bonus Scatter symbols during free spins.

The Free Spins Bonus can be re-triggered multiple times, up to a maximum of 200 free spins.

The number of extra free spins awarded depends on how many additional Bonus symbols land.

• Two Bonus symbols - two additional free spins 
• Three Bonus symbols - ten additional free spins
• Four Bonus symbols - 20 additional free spins
• Five Bonus symbols - 30 additional free spins

A different set of reels are used during the Free Spins Bonus, which begin at three symbol positions high.

The Reel Expansion feature is active during the Free Spins Bonus.

An accumulating multiplier is active during free spins, with a starting value of 1x.

The accumulating multiplier value increases by one every time a Key symbol lands in the active reel window.

Free spins are played at the same coin value as the triggering spin.

The Free Spins Bonus ends when no more free spins remain or after 200 free spins have been played.
