Slot Summary

A darker alternative to the Rich Wilde series' traditional book format is the gap Tome of Madness fills. Play'n GO's fourth Rich Wilde chapter sends the explorer into a Lovecraftian horror story, then replaces paylines with a 5x5 Cluster Pays grid and cascading Avalanche play. The result treats the franchise less like a conventional book slot and more like a high-volatility system of changing symbols, wild multipliers, and successive cluster wins.

How It Plays

Winning clusters disappear through the Avalanche feature, allowing new symbols to enter the grid and create another cluster before the sequence ends.

Symbol Swap and Remove Symbols alter which icons remain available, while Colossal Reels can change how much of the 5x5 field a symbol occupies.

Theme & Atmosphere

Horror and Action & Adventure meet through Rich Wilde's encounter with H.P. Lovecraft's Cthulhu Mythos, shifting the series toward a more ominous fantasy setting.

Book, Magic, Mystic, and Fantasy motifs support the story of forbidden knowledge, while the Cult of Cthulhu reference gives the conflict its Lovecraftian identity.

Features & Win Potential

Random Wilds can change the useful area of the grid between cascades, and Wild Multipliers increase the value attached to those altered positions.

Symbols collection (Energy) supplies an additional objective across the changing grid, while Symbol Swap and Remove Symbols reshape the available cluster patterns during successive results.

Bonus & Free Spins

Free Spins separate the longer feature sequence from the base game, carrying Cluster Pays, Avalanche results, and Wild Multipliers into repeated grid resolutions.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (94.52%), with wins capped at its top multiplier (2,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
