Mysterious Bonus Features

Random Spin Features

On any spin of the standard game, one of three features can be applied, all of which feature wild symbols. Lord wilds will have a multiplier of 2x or 3x attached, which can be combined, while Lady wilds can expand to reveal mystery stacked symbols to potentially enhance wins. Finally, the Baron wilds can infect nearby symbols, turning them wild too.

Free Spins

There are two Free Spins bonus rounds to be found in Mysterious slot, and landing three or four scatter symbols on the reels will give you the choice between them. Locking Multiplier Free Spins will add clock symbols to the reels, which can have a multiplier of 3x, 6x, 9x, or 12x attached. Two clock symbols landing on a single spin will add two more Free Spins to your haul. Meanwhile, the Resurrecting Roaming Wilds Free Spins will see wild symbols added, that then fade and move around. They can come back into play whenever any further wilds land on the reels, potentially boosting wins.
