In the Play’n GO’s 2019 slot Tome Of Madness, protagonist Rich Wilde is taken on an adventure into a realm inspired by H.P. Lovecraft’s famous fictional universe of the Cthulhu Mythos. The game is hugely popular for its dark theme and homage to the author, as well as its numerous special features.
The Tome Of Madness slot is set within what looks like an abandoned church, and its symbols include a tome, explorer Rich Wilde himself, mega wild symbols in the form of a tentacled cyclops monster, a Cthulhu necklace, a dagger, a ring, a Cthulhu skull, and purple, red, blue, and green gems.
Tome Of Madness Slot Basics
The Tome Of Madness slot is played on a 5×5 grid that uses a cluster pays mechanic, and the slot has an RTP of 94.52% with high variance, which means you’re more likely to land infrequent large wins when playing. The bet values range from £0.10 to £100 per spin, and you can get a maximum payout of up to £10,000 times your bet. To make these wins, you’ll need to land clusters of four or more identical symbols.

At the highest bet, the highest-paying symbol is the Cthulhu necklace, which pays £200 for a cluster of four symbols, £400 for a cluster of five symbols, £800 for a cluster of six symbols, £1,600 for a cluster of seven symbols, £3,200 for a cluster of eight symbols, £5,000 for a cluster of nine symbols, and a maximum of £10,000 for a cluster of ten or more symbols.
After this, the dagger pays up to £6,000, the ring pays a maximum of £4,000, the Cthulhu skull pays up to £3,000, and the purple, red, blue, and green gems pay £600, £500, £400, and £200 respectively.
Special Features
The Tome Of Madness slot comes with plenty of bonus features. For example, there are three wild symbols; the special wild, which triggers portal effects; the multiplier wild, which doubles all wins; and the mega wild, which moves down the grid to create rewarding opportunities. All wild symbols substitute for all regular symbols.
Landing winning clusters charges a meter on the side of the slot and for each charge, two special wild symbols are added to the grid. If you win with one of the wild symbols, you can trigger the abyss, which removes an entire row or column, or the void, which removes one type of randomly selected symbol.
There are also eye marks in the game. Forming a win in the eye mark’s location will add two special wild symbols to the grid. Opening the eye awards two special wild symbols when no more wins are made and during the other world free round, opening all eyes summons the mega wild symbol.
After winning on 42 symbols and fully charging the game’s meter, you’ll enter the other world free round. For every three additional winning symbols, an extra portal effect is awarded up to a maximum of seven. During the feature, one random portal effect is triggered when no more wins are achieved. The free round ends when all portal effects have been used.
