Mysterious Bonus Features

When you look at the Mysterious bonus features, the game is promising right from the start. It comes with random spin features, free spin modifiers and resurrecting roaming wilds. Are you spooked out yet? Let’s dig deeper.


You’ll play with three different types of wilds in the Mysterious slot game, which can be activated randomly. Although each wild is rich in diverse qualities, you’ll soon learn that they still substitute for all symbols except for other wilds and the free spins icon. Here goes:

  • The Lord: With this wild, you’ll be rewarded up to x3 multiplier. Plus, multiple wilds of a kind multiply each other.
  • The Lady: Once the Lady paid any wins available, it may expand revealing more mystery stacked symbols which will be useful for creating more winning combinations.
  • The Baron: Expect all bordering symbols to be affected by the Baron and turn wild as a result.

Scatter Symbol

In the Mysterious online slot, the Free Spins symbol is the scatter. By hitting 3 or 4 of these anywhere on the reels, you’ll trigger up to 12 free spins.

Free Spins Feature

In the Mysterious free spins feature, the reels shift from 4 reels to 6 reels transforming the slot into a mighty 4,096 ways to win game. But before you get started, you must choose between two modes. Here are your options:

The Locking Multiplier Free Spins mode:

In this mode, look out for a golden clock symbol. When one of them lands, you’ll get a multiplier bonus of up to x12 that applies to the total win of the spin. Hit 2 or more and you’ll collect 2 extra free spins to play instantly, with the multiplier frozen in place.

The Resurrecting Roaming Wilds Free Spins mode:

During this mode, an intricately framed eerie wild symbol lands on your reels. After each spin, these wilds fade away and roam the reels like ghosts with a prospect to resurrect at the end of each free spin. They can land in random places given more wilds land on the reels.

Mysterious Jackpot

There’s no mention of the Mysterious progressive jackpot, but there’s a fantastic max payout of 9,648x your stake if you bet max. You go, Pragmatic Play!

RTP and Volatility

This is a highly volatile slot, with the Mysterious volatility being set to sky-high. Perfect for the thrill-seekers. The Mysterious RTP is currently at 96.5% but can vary from casino to casino. Be sure to check before you start playing.

Mysterious Bonus Spins

Seeking out Mysterious bonus spins is a smart move because you get to test the slot for free before playing for real money. If you don’t know where to look, we recommend LeoVegas, Dunder and 21Prive Casino.

Mysterious on Mobile

Being a mobile-friendly slot, Mysterious will be a great addition to your mobile casino slots collection. It works great on all devices and appears as dramatic on a smartphone as it does on the desktop.
