Tome of Madness Slot Game Overview

Tome of Madness has a high volatility rating and a Return To Player (RTP) percentage of 96.59%. The game can be played with bet amounts ranging from £0.10 up to £5 per spin. 

The slot is set in a dark abandoned hall with Rich Wilde standing to the right of the reels. The glittery symbols on the reels effectively contrast the dark and gloomy backdrop. 

The low-paying symbols of this online slot are the green, blue, red, and purple crystals. While high-paying symbols include Cthulhu skull, ring, dagger, and octopus pendant icons. 

You can earn a win if 4 or more matching symbols land horizontally or vertically adjacent to each other on the reels. A cluster of 10+ matching symbols could pay out up to 6x your stake for low-paying symbols and up to 100x your stake for high-paying symbols. 

Tome of Madness features 3 wild symbols: the Special Wild, Multiplier Wild, and Mega Wild. Special Wilds activate Portal Effects, Multiplier Wilds could double any winnings, and Mega Wilds move down the grid. The wild symbols can replace all regular-paying symbols.

Eye Marks

If you land a win in the Eye Mark's location, two special wilds may be added to the reels.


Landing wins charges the Portal. As the Portal charges, it can add 2 special wilds to the reels. Landing a win with one of the special wild symbols can trigger the Abyss or Void feature. Abyss removes a row or column from the reels, while Void removes all instances of a single random symbol.

Other World Free Round

If 42 symbols have been involved in winning combinations, the Portal opens and the Other World Free Round triggers. 

Landing 3 extra winning symbols activates another Portal Effect, which can be triggered up to 7 times. The Free Round ends if all Portal Effect has been used up.

Cascading Wins

All winning symbols in the game are removed from the reels and replaced with new symbols from the top reels. This could lead to numerous consecutive wins from a single spin.

Return To Player (RTP): 91.59%

The RTP is a theoretical value and is shown as a percentage. It’s used to describe the percentage of money wagered a particular casino game may pay back to players over a certain period of time.

For example, if a game had a RTP of 92%, in theory, this would mean that for every £100 wagered, the game could return £92 back to players in potential winnings. However, it is important to note that winnings are completely random, and players are not guaranteed to receive this.
