Rich Wilde and the Tome of Insanity: Slot Overview

Howard Phillips Lovecraft, more widely known as H. P. Lovecraft, is often credited as the originator of cosmic horror, responsible for landmark works like At the Mountains of Madness, The Shadow over Innsmouth, and the standout The Call of Cthulhu. His impact has spread across books, films, tabletop games, and online slots. Sometimes those nods are understated; other times they’re unmistakable, and Play’n GO’s Rich Wilde and the Tome of Insanity firmly falls into the second camp. A sequel to the 2019 release Tome of Madness, this time Rich is joined by Yog-Sothoth—an eye-covered cosmic being, one of the Outer Gods, and a key figure in the Cthulhu Mythos. ‘Past, present, future, all are one in Yog-Sothoth.’

After the salt-and-pepper look seen in Rich Wilde in Rich Wilde and the Wandering City, the hero here seems to have somehow turned back time, appearing as a younger version of himself. Rich stands on the right side of the screen beside the reels, set in a candlelit room. Overall, Play’n GO uses the Lovecraftian angle well, particularly during the Damnation Free Spin where Yog-Sothoth can show up. That said, it also wouldn’t have hurt if the studio pushed the theme even further—perhaps taking a cue from Print Studio’s Darkness—but what’s here works nicely.

Symbols land on a 5×5 grid, and wins are formed when 4 or more matching symbols connect vertically and/or horizontally. Any winning symbols are removed, with new ones dropping in to refill the space. Cascades continue until no further winning clusters can be created. Behind the scenes, the game runs on a medium volatile (6 out of 10) model, and the standard RTP among the available return setups is 96.2%. When you’re ready to face the madness, stakes can be set from 10 c to $/€100.

Tome of Insanity’s paying symbols are split into gems and items. The four gems make up the lower-value group, while the higher-value items are potion bottles, severed tentacles, pocket watches, and cyclopean skulls. Clusters of four pay 0.1 to 2 times the bet, while clusters of 10+ return 3 to 100 times the bet.

Rich Wilde and the Tome of Insanity: Slot Features

Rich Wilde and the Tome of Insanity is a cluster-pay slot with cascading wins, where every win helps fill a meter that unlocks features at different points. The end goal is reaching the Damnation Spin, where Yog-Sothoth can appear and act as a wild symbol.

Wilds

All of the wilds substitute for all symbols. Book Wilds may trigger portal effects, while the Multiplier Wild brings multipliers of x2, x3, x4, or x5 in the base game or x2, x3, x5, or x10 in the bonus game. When more than one Multiplier Wild is present in a winning cluster, only the highest multiplier is applied. Multiplier Wild and Yog-Sothoth Wild values are multiplied. Yog-Sothoth Wild is a 2×2 wild that walks 3 times on the grid.

All-Seeing Eyes

An All-Seeing Eye may be created in the base game, while Damnation Free Spin offers 12 regular and 6 special eyes. They sit on the grid below regular symbols. In the base game, opening an All-Seeing Eye occurs by forming a win on its location on the grid, awarding 2-4 book wilds. These wilds are added when no more wins are formed.

Portal

All winning symbols charge the Portal meter: 8 charges award 2-4 Book Wilds while 16 charges award another 2-4 Book Wilds – winning with these triggers Harvest. Harvest destroys symbols in spots 2 symbols away in all diagonal directions, and all spots 3 symbols away in all horizontal and vertical directions, if possible. Get 30 charges to be awarded 2-4 Book Wilds, and winning with these triggers Abomination. Abomination upgrades a gem to a ritual item. Make it all the way to 48 charges to win the Damnation Free Spin.

Damnation Free Spin

Once 48 charges are achieved, a Damnation Free spin is guaranteed with 3 Portal features, though the Portal may be overcharged to gain an extra Portal feature for every 4 additional winning symbols, up to a maximum of 7. After a cascade ends with no win, one random Portal feature activates, continuing until all have been used. Damnation Spins finish when every Portal effect has been resolved. During the Damnation Free Spin, opening every All-Seeing Eyes calls in the Yog-Sothoth Wild, and if you also open 4, 5, or 6 All Seeing Multiplier Eyes, it gains x2, x3, x4 multipliers respectively.

Rich Wilde and the Tome of Insanity: Slot Verdict

Rich Wilde had been notably missing for a stretch, and since the original Tome of Madness landed in 2019, it almost felt as if the series had moved on. Rich Wilde and the Tome of Insanity proves there’s still plenty of adventure left in the fearless explorer, and with Rich looking as refreshed and youthful as ever, there may be more mileage in him yet.

As you step into the game, one thing is clear: if you’re into Lovecraft and the Cthulhu Mythos, Rich Wilde and the Tome of Insanity is well worth checking out. If this ends up becoming a trilogy of Lovecraft-inspired slots, that would be a welcome development. The Mythos has shown itself to be incredibly rich material, and a bolder, darker dive into the stories would be exciting for fans. On the mechanics side, Play’n GO has built enough of these “wins charge a meter” titles that it’s practically second nature, and Rich Wilde and the Tome of Insanity is another solid, enjoyable entry. In a few respects it recalled the heavy metal-themed Lordi Masters of Rock—in mood, in how the charge system builds, and in the fact that reaching full capacity results in 1, yes 1 free spin.

If Yog-Sothoth is ‘the key and guardian of the gate’ as the texts claim, then Rich Wilde and the Tome of Insanity is a gateway to some satisfying cluster-pay gameplay for Lovecraftian lore fans, with a top prize of up to 5,000 times the bet.
