The slot is set in Victorian times, and every leading character of this slot has something to hide. It oozes doom and gloom, and an atmosphere full of fog, dark alleys, and mysterious country houses sets the tone. There is also a big storm building up to top it all off, complete with lightning and rain.

Luckily, the three main characters are on your hand to help you with mystery features so that you can rake in significant amounts of money. Well, clear skies follow storms.
Pragmatic Play seems to be heading for an excellent 2020. Their first new release of 2020 was the insane Release The Kraken, and also their second new slot, Mysterious, is an absolute gem.
The theoretical payout rate is 96.5%, which is excellent and better than the average RTP of a run of the mill online slot. Actually, most Pragmatic Play slots have a Return to Player of 96.5%. We are happy to see that it’s in the ballpark, although it’s not enough to make it to our top 10 best-paying slots.
We expect that the maximum win must be at least 10,000x the bet. It’s not formally published by Pragmatic Play, so it could well be higher than that! However, many non-winning spins or disappointing bonus rounds are inevitable in return with such large possible profits.
According to Pragmatic Play (a score of 5 out of 5 for the volatility), the variance is high. Wins exceeding 2,000x the bet must be possible with this slot.

Mysterious is a win all-ways slot. The base game has 4 reels with 4 rows of symbols, creating 256 ways to win.
Wagering can be done with a bet range between $€ 0.10 and $€ 100 per spin.
During the free spins bonus, the playing field is increased from 4 to 6 reels. So the maximum value per symbol is determined by a 6-of-a-kind.
The highest paying symbol is the beautiful gold Mysterious logo, and yields, with six the same, 25 x the total wager.
The high symbols consist of four of those old-fashioned, solid door handles. These are worth between 3 x and 10 x the total bet for six identical ones.
The four card symbols (hearts, spades, diamonds, clubs) are worth a maximum of only between 2 x and 2.5 x the bet.
By the way, these low symbols only payout when you hit 4 of the same symbols or upwards. So that you know: the high symbols yield a price starting from a 3-of-a-kind.
There are three mystery boosters, which are activated by the then acting character. The mechanism is very similar to that of Moon Princess, and it ensures the base game remains attractive.
The Lord: 1 or more Lord wilds part of a winning combination contain multipliers of x 2 or x 3.
The Lady: if the Lady Wild is part of a winning combination, she expands and changes into a stack of mystery symbols for a chance at super big wins.
The Baron: the baron changes neighbouring symbols into more wild symbols.
3 or 4 scatters will reward you with 8 or 12 free spins.
The playing field is now considerably increased: from four to six reels—the number of ways to win changes just as dramatically: from 256 to 4,096 ways to win.
You can choose from the following free spins bonuses:
Locking Multiplier Free Spins: spin clocks on reel 1 and/or reel 6 for extra multipliers and so-called “locked free spins.” These are free spins with an additional high multiplier.
Resurrecting Roaming Wilds Free Spins: once spun, wilds don’t disappear but start “haunting.” Bring them back to life by creating another wild. A lot of wilds means possible monster payouts.
Mysterious is an excellent Pragmatic Play slot game, well-crafted, with lots of cool features.
And, last but not least: you can bring fat wads of cash home with it.
