For some reason the Victorian era consistently finds itself associated with the eerie and macabre. Mysterious from Pragmatic Play definitely plays on this perception, with a thematic slot that harnesses some very intriguing gameplay. The grid is set up with reels that can be 4 reels or 6 reels wide. The paylines work in a similarly unsettled way, ranging from 256 and going up to 4096 ways to win.

Many players will be drawn to the excitement of a changeable grid, but if you’re not one of them, maybe the 20,000 x your bet top prize will seal the deal. Read on to find out what combination of special features go along with this chilly Victorian game.

Mysterious - Theme and Background

Mysterious 400 x 600 Maybe it’s the top hats, or maybe it’s the severe hairstyles and tightly buttoned collars. Whatever the reason, the Victorian era evokes feelings of repression and austerity that murder mysteries and horror movies cut their teeth on.

In this case we’re talking slots, but it’s not exactly an original theme even with the online casino world. Remember Microgaming’s A Dark Matter? Pragmatic Play have followed the trend and added their own spin on it.

You’ll be welcomed to the scene of a frosty London street, where a derelict manor house dominates the skyline. The game is presided by three enigmatic characters, each of whom appears to be up to no good. All we really know about them is that they’re a Lord, a Lady and Baron. Vague enough to remain intriguing I’d say.

The design is good and fairly engaging, definitely one of Pragmatic Play’s better looking games. The three characters appear on the reels as well as on to the left of the grid (more on this below).

They’re joined by a Scatter, lions, owls, rams, and bulls. Bringing up the rear are a series of low-value card suits.

Mysterious - Gameplay

Despite the game only having one special feature, it’s both busy and rewarding enough to keep the gameplay interesting. Besides, there’s plenty to look out for in the base game alone. Here’s how things play out:

Mysterious Wild Modifiers

Wild Modifiers

There are 3 different wilds in the base game that change according to the game mode. Each one is represented by its own troubled-looking Victorian character. The highlighted character on the side of the reels signifies which mode and wild is active on the reels. Players have no control over which one is highlighted.

No matter which one is engaged, they will always act as normal wilds by substituting for any of the regular symbols. Here’s how each wild is characterized:

  • The Lord Wild will reveal a multiplier of 2 x or 3 x whenever it’s part of a winning combination. If more than Lord Wild lands, then they’ll multiply each other for extra wins.
  • The Lady Wild will expand to form a stack of mystery symbols to hopefully create more winning combinations. This will only happen if the Wild is part of an initial winning combination and only expands after the initial prize is paid out.
  • The Baron Wild will change nearby symbols into more wilds when part of a winning combination.
Mysterious Free Spins

Free Spins

As Free Spins games go, this one is fairly exciting. This is largely due to the fact that players can choose which type of bonus game they’d like to kick off. But before we get into that you should probably know that 3 or 4 Scatters must land before you’re offered the choice. The Scatter is labeled with the words ‘Free Spins’ so you’ll know it when you see it. 3 Scatters will get you 8 Free Spins, and 4 Scatters will get you 12 Free Spins. Triggering the game will take you off the streets and into the eerie manor house. The reels will also expand to 6 and players will now have up to 4,096 ways to win. And now it’s time to make your choice between two games.

Locking Multiplier Free Spins

Locking Multiplier Free Spins

A clock symbol is introduced and when one lands it awards a random multiplier of x3, x6, x9, or x12 which is applied to the total win of that spin. If two clocks land, then 2 extra free spins are played with the multiplier locked at that level for both of them.

Resurrecting Roaming Wilds

Resurrecting Roaming Wilds Free Spins

Rolls off the tongue doesn’t it? Well, if you opt for this game instead, you’ll be in for guaranteed wilds with each spin. If Wilds land on the reels on a spin then they’ll turn ghostly and float around for all remaining spins, landing in random positions for each spin. If another wild lands in view during a subsequent spin, then they will join the ghostly wilds for the rest of the game.

Mysterious - Payouts and Wagering Limits

Wagers can be set starting at C$0.10 and going up to C$100. That’s a great range because it will suit all kinds of players. Going low might well be worth it in this case, because staying power means you’ll have a bigger shot at accessing the game’s special features — which are sitting on wins of up to 20,000 x the stake.

Of course, achieving the top prize isn’t exactly what I’d call likely, but there are plenty of other healthy hauls to walk away with, helped along considerably by wagers of up to 12 x. The volatility level is nothing to play around with, it scores a 5 out of 5 on Pragmatic Play’s scale, so expect a few round of dry spins that could bring more than a single tear to your eyes.

That being said, the RTP is set at 96.50%, which is slightly more than average a welcome softener to this haunted manor of a slot.

Mysterious - Final Verdict

Mysterious 270 x 218

Final Verdict



In terms of theme and design, this is definitely my favorite Pragmatic play slot yet. The storyline and setting gives a very Sherlock Holmes vibe that goes down well with a lot of players. And even though a manor house and noble title isn’t up for grabs, a prize of up to 20,000 x your bet is. The high numbers come with equally high volatility, which will be an immediate turn off for a certain group of players.

To those who are ready for the challenge, and have the bankroll to support the sometimes punishing gameplay, then this Mysterious slot is sure to be a thrilling ride.
