Mysterious online slot game

Mysterious slot was released in 2020 giving players a spooky theme with 243 up to 4096-ways-to-win on 4x4 and 6x4 reels. Free spins unlock more ways to win and multipliers, while in the base game 3 separate wild symbols infect the reels with stacked and spreading wilds as well as multipliers.

Theme and Story Line

Players will visit the Victorian age in 19th century England where ghostly happenings infect the city as ‘The Lord’, ‘The Lady’, and ‘The Baron’ ghosts haunt the reels. Although they are may seem scary at first, these ghosts are not here to shock you not with fear but with big wins!

Graphics, Sounds, and Animations

Pragmatic Play has become an accomplished software developer and it shows in the Mysterious video slot gameplay. A dark Victorian age city background with a haunted house on a hill, animated lightning, the sound of whirling winds and howling wolves set this slot game’s eerie tempo. On the reels, the symbols are just as creepy and will trigger various animations when feature bonuses are triggered such as the resurrecting wilds which are creepy but also helpful.

Overall, the Mysterious video slot game blends in all the right graphics, colours, animations, and sound effects to bring players an atmospheric Victorian-era ghost story to the reels.

During the base game of the Mysterious online slot, players will spin on 4x4 reels with 243-ways-to-win. These reels can be expanded to 6x4 and 4096-ways-to-win if the free spins bonus is triggered.

In the base game, you will be spinning 9 regular symbols that pay for 3 and 4 symbol combinations. These symbols can also be linked up into 5 and 6 symbol combinations when the free spins game is triggered. All these symbols can be substituted by any of the ghosts which are all wild symbols. When the ghost wild symbols appear, they will also infect the reels with a feature that could be stacked wilds, multipliers, or spreading wilds.

All combination wins during either the free spins game or the base game must begin with the first symbol on reel 1 and appear on subsequent adjacent reels running from left to right. As a result, if you land a 3-symbol combination, it will be on reels 1-2-3. If you see the same symbol on reels 1-2-4, this is not a winning combination as there is no symbol on reel 3.

Game options available to you include volume control, quick spins, sound FX, ambient music, and battery saver (reduces animations). You also have an ‘Autoplay’ option that will allow you to set between 10 and 100 automatic reel spins.

Bonuses and Free Spins

Random Spin Wild Symbol Modes: On the left of the reels you will see the 3 ghosts of the Mysterious online slot game. Whichever one is activated is the wild symbol feature you will receive.

  • The Lord: Multiplies wins it completes by x2 or x3
  • The Lady: Expands into a mystery stack of symbols
  • The Baron: Spreads onto adjacent reels giving you more wilds

Free Spins: Land 3 or 4 free spins scatters for 8 or 12 free goes on the reels respectively. The reels will become 6x4 and you will have 4,096 ways-to-win plus 2 additional features.

  • Locking Multiplier: A gold clock landing on the reels during free spins will multiply all wins by 12, 9, 6, or 3. When 2 land simultaneously, an additional 2 free spins will be played immediately with the multipliers locked in place.
  • Resurrecting Wilds: During free spins, any wild symbol that hits the screen will fade away and randomly appear in another position on any given spin.

Bet sizes, RTP and Variance

Min-max bets are 0.10-100.00 per spin. Bets are set using the -/ options where you have ‘Bet’ and ‘Coin Value’ options. The ‘Bet’ option can be set from level 1 to level 10 with each level playing 10 coins per spin, therefore, at Level 10, you will be placing 100 coins on the spin bet. The ‘Coin Value’ can be set from 0.01 to 1.00. As a result, 100 coins at level 10 multiplied by the max ‘Coin Value’ of 1.00 provides you with a 100.00 max cash bet per spin. The Mysterious online slot’s expected RTP is 96.5% and Pragmatic Play has rated the gameplay's volatility as 5 out 5 thus providing you with high variance gameplay.


The mysterious online slot is obviously very different from most other slots being released. Players can trade in traditional gameplay in favour of 4x4 reels that provide the chance to expand their gameplay over 6x4 reels, which is when players really begin to roll in the big win. The increase to 4096-ways-to-win really does make all the difference – especially with the addition of the locking multiplier and resurrecting wild symbols during the free spins bonus.
