Tome of Madness

About Tome of Madness

Tome of Madness is the fourth entry in Play'n GO's Rich Wilde series and its full title is Rich Wilde and the Tome of Madness. Released in 2019, it swaps the reels of Book of Dead for a 5x5 cascading grid and moves the setting from Egyptian tombs to the Cthulhu Mythos of H.P. Lovecraft. Rich Wilde stands beside the grid holding the book itself, and the whole presentation is built around dim light and green fog.

Structurally the game belongs to Play'n GO's grid family alongside Reactoonz. Winning clusters charge a Portal Meter, and the meter drives a sequence of effects that reshape the board. Maximum win is 2,000x stake, which is low for a high-volatility title, so the appeal sits in how the features chain together rather than in the ceiling.

How to Play Tome of Madness

Four or more matching symbols connecting horizontally or vertically form a winning cluster. Diagonal connections do not count. Winning symbols are removed, new ones drop in from above, and cascades continue while wins keep forming. Stakes at Midnite start from £0.10 per spin.

Every symbol that forms part of a win adds to the Portal Meter shown beside the grid. Passing set thresholds awards Special Wilds and sets off Portal Effects, which remove rows, columns or blocks of symbols and feed those removals back into the meter. Filling the meter completely opens the Other World Free Round, a single bonus round where Eye Marks cover the grid and opening all of them brings in a moving Mega Wild.

Tome of Madness Features

• Cluster Pays: Wins are formed by 4 or more matching symbols connecting horizontally or vertically. There are no paylines.
• Cascades: Winning symbols are removed and replaced from above, so a single spin can produce several consecutive wins.
• Portal Meter: Every winning symbol charges the meter. Reaching set thresholds awards Special Wilds and triggers Portal Effects.
• Portal Effects: The Abyss effect removes a row or column from the grid. The Void effect adds Special Wilds. Symbols cleared by either effect feed straight back into the meter.
• Three Wild Types: The Book acts as the standard Special Wild, Rich Wilde acts as a 2x Multiplier Wild, and the Mega Wild appears only in the bonus round.
• Eye Marks: Marked positions appear at random. Forming a winning cluster on one awards two Special Wilds on the next losing cascade.
• Other World Free Round: A single bonus round where the grid starts covered in Eye Marks. Opening all of them brings in a 2x2 Mega Wild that moves down the grid with every cascade.

Tome of Madness Theme and Symbols

The grid sits inside a dark hall lit by a single source, with Rich Wilde on the right holding an open book that reacts as the meter charges. Play'n GO leaned into Lovecraft's cosmic horror rather than the pulp adventure tone of the earlier Rich Wilde games, and the sound design carries most of that shift. The Portal Meter and a small grid map showing Eye Mark positions both sit to the left of the play area.

Low-value symbols are four coloured crystals in purple, red, blue and green. Premium symbols are Cult of Cthulhu artefacts: a Cthulhu skull, a gemstone ring, a dagger and an octopus pendant, with the pendant paying most. The Book is the standard Special Wild, Rich Wilde himself doubles any win he completes, and the 2x2 Mega Wild appears only inside the Other World Free Round, where it steps one row down the grid with each cascade.
