Rich Wilde and the Tome of Madness

Rich Wilde and the Tome of Madness is a 2019 entry in Play’n GO’s Rich Wilde adventurer series, trading Book of Dead’s Egyptian setting for a Lovecraftian horror theme. It plays on a 5×5 grid using cluster pays rather than paylines or Book of Dead’s classic 5×3 layout: groups of four or more matching symbols connected horizontally and/or vertically form a win, after which winning symbols clear and new ones cascade into place.

The game’s central mechanic is a rising “madness” meter that fills as symbols are collected during play, eventually unlocking modifiers that alter the reels — extra wilds, symbol upgrades or added multipliers — before a free spins round in which those modifiers stay active, compounding the potential payout. This structure gives it a slower-building, more escalating feel than Book of Dead’s straightforward pick-bonus format.

Rich Wilde and the Tome of Madness runs at a 96.59% default RTP (with 94.52%, 91.59%, 87.52% and 84.50% variants available to operators), is rated high volatility, and caps out at a 2,000x maximum win — considerably lower than Book of Dead’s ceiling, reflecting its more frequent, cluster-driven payout style rather than a single big free-spins jackpot moment.
