Mysterious review

Theme and Style

Mysterious is themed around a spooky, supernatural world.

On a dark and stormy night, players will find themselves in a town where uncanny forces are afoot. They’ll need to befriend some eccentric characters if they want to make it to morning.

Fans of gothic narratives such as Dracula will especially appreciate this slot’s dark atmosphere.

Graphics, Sounds and Animations

The eerie soundtrack is filled with tinkling notes and dramatic organ chords. Ghostly moans are blended into the music to emphasize the haunting vibe.

On the reels, players will see a variety of elegantly carved door knockers. Each one portrays a different animal, including lions, rams, owls, and bulls, all with glowing eyes.

Hearts, diamonds, clubs, and spades also make an appearance among the symbols in the form of different gems. Ornately engraved backdrops give each of the card suits symbols even more flair.

Beside the reels, The Lady, The Lord, and The Baron characters sit in golden frames. They wear historical ensembles and grave expressions, making it easy to imagine them in an intriguing story together.

In the background, players will see a dark village with a full moon and flashes of lightning overhead. On a hill sits an intimidating manor that brings to mind the iconic settings of stories such as Frankenstein.

Overall, the music and animation of Mysterious creates a moody gothic world.

Wilds, Bonuses and Free Spins

The Lord appears only on reels 2, 3, and 4 during the base game.
• The Baron: Substitutes for every symbol excluding the other Wild symbols and the Free Spins symbol. The Baron has the special ability to transform vertically adjacent symbols into Wilds. The Baron appears only on reels 2, 3, and 4 during the base game.

The Free Spins feature is triggered when players land at least 3 Free Spins symbols. If the feature is triggered by 3 Free Spins symbols, 8 free spins are awarded. Meanwhile, if the feature is triggered by 4 Free Spins symbols, 12 free spins are awarded.

Special reels are used for the Free Spins feature, and prior to the feature starting, players must choose from two versions of the feature:
