The Mystical Powers
In the depths of a mansion glowing in the candlelight, Rich Wilde attempts to create wins from gemstones and ritual artefacts in order to activate secret runes. The free spin takes Rich straight to Yog-Sothoth’s humble abode, where only one of them can emerge victorious. The sound effects add another layer of mystery as Rich Wilde confronts his fears.
On the 5x5 grid, wins are formed as clusters when at least four identical symbols are connected horizontally or vertically. In addition, cascading symbols can create new wins during a single spin. When a cluster win is removed from the grid, new symbols drop down to fill the empty spaces. This process continues until no more wins are formed.
Who is Rich Wilde and the Tome of Insanity suitable for?
If Rich Wilde’s adventures are familiar, Rich Wilde and the Tome of Insanity is unlikely to disappoint. Bonus features such as versatile Wilds, the Portal, and the All-Seeing Eye, which also appear in other games in the series, such as Rich Wilde and the Tome of Madness and Rich Wilde and the Tome of Dead, are present here as well. Meanwhile, Rich Wilde and the Pearls of Vishnu is a little more traditional, with wins formed on paylines and having simpler bonus features.
In Rich Wilde and the Tome of Insanity, wins can theoretically occur fairly regularly thanks to the game’s medium volatility, keeping the gameplay pace steady. The Portal charging up with winning symbols and triggering several special features can also lead to longer winning streaks. In addition to its variety of features, the game’s graphics and sound design help maintain the suspense and create a distinctly gothic atmosphere.
Special Features
Wild Symbols
The game features several different Wild symbols, each with its own unique properties. However, all Wilds substitute for regular symbols, helping to create winning combinations.
The Portal levels introduce Book Wilds to the game, while the Multiplier Wild, featuring Rich Wilde himself, adds win multipliers in both the base game and the bonus game. If multiple Multiplier Wilds are included in the same cluster win, only the highest multiplier is applied.
When the Yog-Sothoth appears, it transforms into a Wild that moves across the grid three times and occupies a 2x2 area. If a Multiplier Wild and a Yog-Sothoth Wild appear at the same time, their values are multiplied together.
All-Seeing Eyes
A smaller grid next to the game layout shows the positions where the All-Seeing Eyes can be activated. In the base game, one eye appears at a time on random spins, and if a win is formed at the position of an eye, the player receives 2–4 Book Wilds once no other wins are formed.
During the bonus game, there can be up to 12 regular Eyes and 6 special Eyes in the game. If a win is formed at the position of a regular Eye, a Yog-Sothoth Wild enters the game. If wins are formed at the positions of 4, 5, or 6 special Eyes at the same time, the Yog-Sothoth Wild is awarded a multiplier of 2x, 3x, or 4x, respectively.

Portal
Each cluster win charges the Portal based on the number of winning symbols, and each Portal level introduces different features to the game. The Portal resets after every spin.
- Ruin is triggered with 8 winning symbols and adds 2–4 Book Wilds to the game.
- Harvest is triggered with 16 winning symbols and adds 2–4 Book Wilds to the game. If the Book Wilds are part of a cluster win, the Wild targets symbols 2 spaces away diagonally and 3 spaces away horizontally and vertically. If there are symbols in those positions, they are destroyed and removed from the game grid, making room for new symbols.
- Abomination is triggered with 30 winning symbols and adds 2–4 Book Wilds to the game. It also transforms a gemstone symbol into a ritual artefact, increasing the symbol’s value.
- Damnation Free Spin is triggered when the Portal is fully charged with 48 winning symbols.
Damnation Free Spin
When the Free Spin feature is triggered, the player enters the world of Yog-Sothoth. During the Free Spins, at least three Portal features are activated. However, if the Portal has been charged beyond 48 symbols before the Free Spin begins, it grants one additional feature for every four extra winning symbols, up to a maximum of 7 features.
Once no more wins are created after a cascade, the player receives one additional randomly selected Portal feature. The bonus game ends once all available features have been used.
