Rich Wilde is back from the South American jungles of Aztec Idols. His latest journey takes him on a quest to uncover ancient artefacts and relics from the Cult of Cthulhu in Tome of Madness, from Play’nGO, with up to 2,000x total bet.

Step into the Abyss

The adventure takes Rich Wilde into the world of the evil Cult of Cthulhu in search of the Book of Madness. No, this slot is not another clone of the popular classic Book of Ra from Novomatic.

For one thing, you find yourself in a dark chamber with ominous lightning and mist sweeping across the back of the 5×5 reels. Step into the abyss with stellar graphics and phenomenal soundtrack!

Cascading Cluster-pays

Tome of Madness is a cluster-pays slot where 4+ symbols connected horizontally and/or vertically create a win. Losing symbols are removed and new symbols cascade to fill the voids which can continue provided new wins are formed.

Tome of Madness – The Eye Marks

Eye Marks, similar to the eye of Horus, can appear in random spaces on any reel. Creating a win in the location of the Eye Mark adds two special wilds to the grid after a losing round.

Abyss Portal Effect & Void Portal Effect

To the left of the grid there is a meter which is charged by wins but resets after a losing round. A win with clusters totalling 7 and then 14 symbols award two special wilds onto the grid. A win that is helped along by one of these special wilds will unlock the Abyss Portal Effect.

Wins on 27 symbols will also add two special wilds. On this occasion, a win helped along by a special wild will unlock the Void Portal Effect.

So what is the Abyss Portal Effect? Well, this is a feature that will eliminate either a column or a row from the winning special wild and help to charge the portal. The Void Portal Effect, on the other hand, will randomly select all instances of a symbol to be removed.

Tome of Madness – Other World Free Round

Continuing to charge the meter to 42 symbols will unlock the Other World Free Round Feature consisting of a free round (spin) containing three random Portal Effects. Collect an extra Portal Effect for each three additionally collected winning symbols – capped at seven.

These portal effects can consist of four special wilds added to the grid, the Abyss Portal Effect or the Void Portal Effect.

On a final note, during the feature, 11 or 12 Eye Marks become noticeable. Open the eyes by winning on their location to unleash the Mega Wild Cthulhu symbol who cascades down by one row on every spin until he disappears.


Tome of Madness slot is a high volatility horror-adventure, based on a fictional grimoire, with variable wagers from 0.10 to 100. It blends an Indiana Jones-like theme with unusual features. With an RTP of 96.59%, you can find it at one of our recommended casinos today!
