About Mysterious slot

The aptly named Mysterious slot is one that fits in particularly well in our Halloween slots category. The backdrop is the haunted house on the hill with some lightning effects above. Meanwhile, the 4x4 reels are quite compact but the boldness of the slot makes it look particularly impressive, especially when the reels flash for the Free Spins bonus round which has two different sections for players to explore. One provides players with a multiplier and the other provides players with roaming wilds. One aspect that sets this slot above a tonne of other Pragmatic Play casino slots is the bonus features. There are three different game modes for players to take in, all of which have significant winning potential.

If you’re playing on mobile, this slot offers the opportunity to play either in landscape mode or horizontal mode, which means that it is perfect for our Mobile Casino players. There are up to 256 paylines for players to win with, but as the reels expand during the Free Spins bonus round, this can increase up to 4096 different ways to win. This means that this particular game almost has as many ways to win as our Megaways slots, which is just one of the many brilliant features of the Mysterious slot.

How to play Mysterious slot

How to set your stake

If you’re looking to play on the Mysterious slot, players must set their stake by using the - and + symbols either side of the spin button on the bottom right of the reel. Doing this will bring up a pop up with “bet”, “coin value” and “total bet” as the three sections that players can change.

Free Spins Bonus Round

Once players land three of the Free Spins symbols on the reels at any point they can activate the Free Spins bonus round. Once activated, two options will appear on the reels giving players the option of Locking Multiplier Free Spins and Resurrecting Roaming Wilds Free Spins. The Locking Multiplier adds clock symbols on the reels that provide a multiplier of either x3, x6, x9 or x12. If players land two clocks, they receive extra Free Spins and the multiplier locks. Meanwhile, in the wilds feature, wilds will float around the reels until the end of the spins.

Wild Modifiers

Players may have noticed the three characters on the left side of the reels. If a character is highlighted, that character's wild features are added. The three characters are:

The Lord - Lord Wilds provide players with multipliers of x2 and x3 to all wins they’re involved in. Multiple Lords will end up multiplying each other to provide bigger wins.

The Lady - Lady Wilds expand after the spin is paid out and provide players with a stack of mystery symbols to create additional wins.

The Baron - Baron Wilds change symbols near to the wild into additional wild symbols.

The Boss Believes: Mysterious Slot review

We think that the Mysterious slot could be the very best Pragmatic Play game on Slot Boss. It takes a lot to stand out in our casino games library but Mysterious does a very good job of doing exactly that. With a plethora of bonus features and with the spooky haunted house on the hill theme, we think that Mysterious slot is definitely the best horror-themed game on Slot Boss. If you’re looking for a different style of slot to try out, why not play Cop the Lot, which is a comedy slot.
