Developed by Pragmatic Play, the brains behind the popular Wolf Gold which ranks highly within our collection of online casino games and the nautical-themed Release The Kraken, this slot is packed full of bonus features each of which can offer thee a myriad of features if the Lord, Lady or the Baron come into play.

A highly thematic slot, the highest-paying symbols on offer within this game have a haunted feel taking the form of door knockers represented by animals with the lion offering the highest potential payouts if you can match four across the reels.

Mysterious Slot Bonus Features

Random Spin Feature

Within the Mysterious slot, players are likely to come across 3 Wilds and in the base 1 of 3 random spin features can potentially be triggered by landing one of the games main characters, the Lord, the Lady or the Baron.

The Lord Feature - This Wild symbol replaces all the symbols bar the other wilds and the Scatter symbol. If they form part of a win, it will give thee a random multiplier and if you land additional Lord Wilds, the values of the multipliers will be multiplied together.

The Lady Feature - If the Lady symbol appears it will expand to reveal a mystery stacked symbol that can potentially form new combinations.

The Baron Feature - This wild infects nearby symbols and transforms them into Wilds.

Free Spins Feature

There are two Free Spins features which can be accessed if 3 or more scatter symbols appear across the game reels. Players will then be transported to a new set of reels which expands from 4x4 to 6x4 and increases the ways to win up to 4096. Depending on the number of Scatters thou lands, players will receive 8 or 12 spins respectively and they will then choose from one of the following options:

Locking Multiplier Free Spins - Landing a clock symbol on the reels will award a multiplier of 3x, 6x, 9x or 12x multiplier which will be applied to the total win of all spins. If two symbols land on the reels, 2 more Free Spins will be awarded with the multiplier locked.

Resurrecting Roaming Wilds Free Spins - Any Wilds that land will fade away following each spin and roam across the reels, they can also return at the end of any spin in a random position.
