Tome of Madness.
Tome of Madness (Play'n GO, 27 June 2019) sends Rich Wilde into Lovecraft country on a 5x5 cluster grid. Winning symbols fill a portal meter; filling it releases special symbols, and filling it 3 times opens the Abyss free-spins round. RTP is 96.59%, volatility high, and the maximum win is 2,000x, which makes it one of the gentler titles in this catalogue.
How it plays.
- Clusters of 4 or more matching symbols pay and are removed; new symbols drop in and the chain continues.
- Every winning symbol fills the portal meter. At set thresholds the Eye of Cthulhu, a Wild Pattern or the Mega Wild feature triggers.
- Fill the meter 3 times in 1 spin to enter the Abyss Spins, where the whole grid is live and the portal effects are stronger.
Features.

Tips.
Editorial tips, no guarantees. The house edge is the same whichever way you play.
- With a 2,000x ceiling this is a session game. It stretches a bankroll further than the 10,000x+ titles and pays its RTP in smaller, more frequent pieces.
- Play'n GO ships lower RTP builds on most titles. Confirm 96.59% in the panel.
- No bonus buy, so the trigger rate sets the pace. 0.5% to 1% stake per spin keeps you in the game for 200 spins.
