About this game

Rich Wilde and the Tome of Madness

Tome of Madness continues the story of adventurer Rich Wilde, this time taking a more mysterious turn. The game revolves around secrets linked to the cult of Cthulhu and the enigmatic Tome of Madness.

Play’n GO builds the atmosphere through dark visuals, mystical symbols and features that gradually unfold as the game progresses. While the slot leans more heavily into theme and atmosphere than previous entries in the series, it still retains the light, familiar pacing the game series are known for.

Inside the gameplay

The slot is played on a 5×5 grid, where wins are formed through clusters of matching symbols that touch each other. A winning combination is created when at least four identical symbols connect horizontally or vertically.

Winning symbols are removed from the grid and replaced by new ones, which can continue the winning chain within the same spin. At the same time, the game’s portal gradually charges and may unlock additional features.

Game Features

The game revolves around the portal and the features it unlocks as play progresses.
