Design and Theme
🖼️ Graphics
A deserted cathedral looms in the background: cracked windows, cold moonlight, and a smug treasure-hunter hugging a cursed tome. Tiles are ornate and heavy, with occult jewellery, knives and carved gems. The UI frames the grid like a grimoire, while the Portal meter on the left glows as if something impatient wakes beneath the floor. The whole screen reads as an antique museum after midnight.
🎶 Sound
The score is a tense, stately theme that never quite resolves. You feel the threat in the low strings. Wins detonate with a bang and a flash, then the grid drops with a mechanical rumble. When chains of cascades build, percussion swells and the mix tightens, which sells the idea that the Portal is about to crack open.

Special Symbols
- Special Wild (book icon): adds to wins and may trigger a Portal effect when part of a winning cluster.
- Multiplier Wild (Rich Wilde portrait): x2 to any win it participates in.
- Mega Wild (Cthulhu eye): a giant wild that appears in the feature and steps downward between cascades, creating new connections.
- Eye Marks (glowing tiles): marked cells on the grid; open an eye by landing a win covering that position to spawn +2 Special Wilds. In the feature, opening all eyes summons the Mega Wild.
Bonus Game
The slot replaces classic free spins with a single escalating round where queued effects fire automatically.
Other World Free Round: charge the Portal by winning on 42 symbols in one paid spin to enter the feature. Extra charge beyond 42 adds more effects: +1 effect per +3 symbols, up to 7 in total. During the round, when no new win forms, one random Portal effect resolves; this continues until all stored effects are spent.
Portal effects:
- Special Wilds: several Special Wilds are added to the grid.
- Abyss: removes a full row or column from the Special Wild that just won; removed symbols also charge the Portal during the build-up.
- Void: selects one regular symbol and removes all its instances from the grid.
RTP, Volatility, Max Win
RTP — 96.59%. Volatility high. Maximum win capped at x2,000 of the bet.
Our Verdict
Rich Wilde and the Tome of Madness is all about momentum. Dead spins feel quiet, then a single cluster wakes the meter and suddenly the grid starts eating itself, stacking wilds and removals until the Portal tips. The one-spin feature is neat: you watch effects discharge like fuses, hoping the Mega Wild lands where it matters.
If you want something simpler, try Legacy of Dead with free spins and expanding symbols. If you want coins and a three-mode FS setup instead: Le Bandit.
