How to Play Skeleton Key


Before playing Skeleton Key, you must set a stake that you wish to bet. You can do this by using the + and - buttons on-screen to adjust the stake currently set. Please remember that you can adjust your stake at any point during the game if you wish.


Once you are content with your stake, begin the game by selecting the main spin button on-screen. This will spin the reels, thus beginning the game! If you wish to use the iconic autoplay function, select the autospin button above the main spin button and choose how many spins you wish to be spun automatically. You are also able to set loss and/or win limits, both of which will stop the function if they are reached.

Skeleton Key Bonus Features

Reel Expansion

The reel window is initially three positions high, however, if a key scatter symbol lands on any reel, they will expand to six positions high. This will then cause the empty reel spaces to fill with symbols from above once the key scatter symbol disappears.

Mystery Symbol

The mystery symbol can appear at any point during the game at random, transforming into any symbol on the reels other than the key scatter symbol, a bonus symbol or wild symbols. If there are multiple mystery symbols on-screen, they all transform into the same symbol, thus potentially leading to a winning combination.

MultiWay Extra Feature

This bonus feature ensures there are 243 to 7,776 ways you can win, following the reel expansion feature.

Free Spins

Three or more bonus scatter symbols landing on the reels will trigger the free spins bonus. Three bonus scatter symbols will award 10 free spins, four will award 20 and five will award 30. Free spins can also be retriggered within the feature.
