Bottom Line: Rich Wilde and the Tome of Madness stands as one of Play’n GO’s most atmospheric and mechanically innovative slots, successfully merging H.P. Lovecraft’s cosmic horror with exciting cluster-based gameplay. While the 2,000x max win might seem modest compared to modern slots, the game’s cascading features and unique Portal system create consistently engaging gameplay that keeps players coming back.
Game Overview
Rich Wilde returns in his fourth adventure, but this time he’s trading Egyptian tombs for something far more sinister. The Tome of Madness is the fourth instalment in Play’n GO’s popular Rich Wilde series, inspired by H.P. Lovecraft’s famous horror writing and packed with spooky music and graphics. The intrepid explorer delves into the mysteries of the Cult of Cthulhu, creating an eerie departure from the series’ usual adventure themes.

Core Gameplay Mechanics
Cluster Pays System
The game uses a 5×5 cascading grid where you need to match four or more symbols vertically, diagonally, or horizontally. Winning symbols disappear in cascades, allowing new symbols to drop down and potentially create additional wins from a single spin.
The Portal System
The Portal meter, located on the left side of the grid, is the heart of the game’s bonus mechanics. Every win contributes to charging the Portal, which unlocks several bonus features at various stages:
- 7 symbols: 2 Special Wilds added
- 14 symbols: 2 Special Wilds + Abyss feature potential
- 27 symbols: 2 Special Wilds + Void feature potential
- 42 symbols: Other World Free Round triggered
Wild Symbols & Features
Rich Wilde (Multiplier Wild): Substitutes for all regular figures by doubling the payouts
Special Wild (Tome Book): Can trigger portal effects and appears when Eye Marks are activated
Mega Wild (Cthulhu): A 2×2 symbol that appears in the bonus round and moves down the grid with each cascade
Eye Marks Feature
Eye Marks are purple squares that appear on the grid – when you make a cluster on one, you get two Special Wilds once you’re out of wins. This feature adds an extra layer of anticipation to every spin.
Bonus Features
Portal Effects
- Abyss: Removes an entire row or column of symbols
- Void: Removes all randomly selected paying symbols of one type
Other World Free Round
Triggered when you land 42 winning symbols, you’ll receive a single free spin where more Eye Marks are added to the reels. For every three symbols collected above the 42 that trigger Other World, you’ll get an extra portal effect added on, up to a maximum of seven portal effects.
Mega Wild Cthulhu: During the Other World free round, you’ll notice 11 or 12 eye marks on the grid. If you form winning clusters over all eyes, the Mega Wild Cthulhu symbol is released and continues to move down the grid with each cascade.
Paytable & Winning Potential
The game’s cluster pay system rewards larger symbol groups with exponentially higher payouts. The highest paying symbols give you 100 times your stake for a cluster of 10 or more symbols. However, the max win of 2,000x will happen every 100 million spins on average, making it a true high-volatility experience.
Mobile Compatibility
You can play on mobiles, but being a 5×5 grid, it can feel a little cramped on smaller devices. The HTML5 technology ensures smooth gameplay across all platforms, though the intricate details are better appreciated on larger screens.
Strategy & Tips
Given the very high volatility, consider these approaches:
- Bankroll Management: The high volatility demands careful budget management
- Feature Focus: The cascading system, along with the Special Wilds and the Portal, mean that once you get on a roll, the wins can keep coming
- Demo Play: Try the free version first to understand the complex feature interactions
Comparison to Similar Games
Both Moon Princess and Viking Runecraft are huge hits, so it’s no wonder Rich Wilde and the Tome of Madness is also a favorite. The game shares DNA with other Play’n GO cluster slots like Sweet Alchemy, but the Lovecraftian theme and unique Portal system set it apart.

Where to Play in 2025
Rich Wilde and the Tome of Madness remains widely available at licensed online casinos. Always check the RTP version before playing, as alternative RTP rates are too low for a high-variance online slot at some operators.
Final Verdict
This is a fresh take on the series with a different theme which has been brought to life through gripping gameplay and a combination of bonus features. The low max win potential might deter some, but the big-bonus action and solid RTP more than make up for this.
Rich Wilde and the thetomeofmadness.com succeeds as both a horror-themed slot and a mechanically sophisticated game. This is a really well-crafted and entertaining slot with the cascading grid and cluster system making it much easier to spot wins straight away. While it may not offer life-changing jackpots, it provides consistent entertainment value and remains one of Play’n GO’s standout releases.
