There’s also the chance for plenty of free spins when you head on this Victori-goth adventure.  Scatter symbols will lead you towards the world of wonder, opportunity and free spins.

Not much of a steamdork? There’s plenty more fun to be had with the rest of our online slots.

Bonus features

Mystery symbols

Mystery Symbol(s) landing on the reels will open to reveal a randomly selected Low, High or Wild Symbol.


Win Booster

You can choose to turn this on or off in the base game and when it is on, it boosts your bet and removes the chance for Mystery Symbols to reveal Low Symbols. Boosting increases total bet by 50%.


Free spins with Mystery Reels

3, 4 or 5 Scatters anywhere on the reels will give you 10 free spins. Landing Scatters during free spins will award one additional spin per Scatter. You could get up to 3 Mystery Reels™, based on the number of triggering Scatters.
