About Skeleton Key Slot

Enter the key and creep through the spooky underground lair in search of hidden treasures in Skeleton Key! As you spin the reels, ancient jewels, golden treasure chests and spell books can be found amongst symbols, surrounded by a layer of green smoke, which instantly sets the mood of this mysterious slot. Brought to us by game developers IGT, Skeleton Key is a treasure hunting-themed slot, set against the backdrop of a gloomy cave, where mountains of glistening treasure can be observed beside the game’s grid. There’s certainly an ominous feel to Skeleton Key, with eerie aesthetics and intensifying audio which players may find similar to slots like Pragmatic Play’s Voodoo Magic.

There’s plenty going on in this slot, packing some stunning visuals alongside a number of exclusive bonus features, making Skeleton Key a fantastic addition to our collection of online slots. This slot boasts a classic 3x5 reel layout, which can be expanded further to 6x5 if you manage to land a key symbol and further increases your winning potential. But what you really want to focus your attention on is the turquoise padlock symbol, where landing three of these in the same spin will trigger the Free Spins bonus feature. Expect some big multipliers and retriggers along the way also, as you spin the reels in search of glistening treasures!

Skeleton Key Slot Special Features

Reel Expansion feature

When landing a winning cluster, this cluster will explode and additional symbols will fall into its position. This process continues until there are no more wins formed.

Beginning with a five reel, three row layout and with 243 ways to win, once you land a key symbol this is expanded by an additional three rows, meaning more symbols and an enhanced number of ways to win, up to 7,776.

Mystery Symbol feature

Keep an eye out for the ‘?’ cube, which is Skeleton Key’s Mystery Symbol. All of these symbols that land on the same spin become the same symbol, and a new payout is calculated.

Free Spins bonus feature

The bonus symbol is the blue padlock symbol. If you can land three or more of these on the same spin, you will trigger the Free Spins Bonus feature. Land three bonus symbols for 10 Free Spins, four bonus symbols for 20 Free Spins and five bonus symbols for 30 Free Spins.
