How to Play

To start playing Mysterious, do the following:

  1. Open the slot
  2. Click on paytable
  3. Read the rules
  4. Bet from €0.1 to €100
  5. Spin the reels

The title has from 256 to 4,096 pay lines. The maximum number of ways to win is activated during the bonus round. The slot also has a standard 4x4 playing field, but after the free spins are launched, it expands to 6 reels. The game has a set of 9 symbols suitable for making combinations.

In addition, during the course of the game, three separate features of the Wilds may be activated randomly. Moreover, the slot has free spins containing a number of bonus features that increase the chances of winning.

Mysterious RTP and Volatility


The RTP of the slot is 96.5%, while the volatility is very high.

The return percentage is a theoretical number that indicates the amount of bets to be returned to the user's balance after they finish the game. You should not think that the game will definitely return 96.5% of the money spent on it because the slot has a random number generator. Thanks to it, you can get much more without relying on RTP.

Volatility is an indicator that is responsible for the amount of prizes in the slot. If it is very high, you can hope for relatively large winnings, which, however, will appear quite rarely in the title.




The title has a rather interesting and high-quality graphic design that perfectly conveys the spirit and theme of the slot. In the background, you can see a city plunged into twilight, dominated by a mysterious haunted mansion. Lightning flashes in the sky and the streets are shrouded in an ominous haze. It seems that from behind any corner a monster can appear here, causing mortal horror.

The soundtrack of the slot is made in a majestic style. The melody carries the tension of the ghost hunt that takes place during the spins of the reels. The set of sounds is completely original, even the classic victorious fanfare sounds very fresh here.

The symbols of the title are four card suits, as well as images of the Bull, Buffalo, Eagle, and Lion, stylized as locks, unlocking some mysterious gates. The most valuable symbol of the game is its logo on a blue background. There are also 3 portrait images of ghosts – Lord, Lady, and Baron. They are Wilds during the base round.

In addition to them, the title has a bonus symbol. It is made in the form of a sign decorated with intricate drawings. The image of a clock stopped at midnight plays the role of a special multiplier symbol here.
