Rich Wilde and the Tome of Madness Slot Review
Fog rolls through a ruined arcade of columns, a stone-and-brass reel frame stands cracked on the flagstones, and Rich Wilde waits at the edge of it with a glowing tome cradled against his hip. Few slots commit to a mood this completely, and this Lovecraftian chapter of Play’n GO‘s adventurer series commits harder than most. The book isn’t decoration – everything that happens on the reels flows from it.
It runs on a 5×5 grid with Cluster Pays, at 96.59% RTP and very high volatility, with wins up to 2,000x the bet and stakes from 0.10 to 100 per spin. It sits alongside Alice Cooper and the Tome of Madness and Book of Dead in the studio’s catalogue, and it’s the format Rich Wilde and the Tome of Insanity later built on.
How the 5×5 Grid Pays
Wins need four or more matching symbols touching horizontally or vertically anywhere on the grid. There are no paylines to trace and no reels to read left to right – a cluster in the middle of the grid pays exactly the same as one hugging the edge.
Winning symbols are then removed and symbols fall down to fill the gaps, so one spin can chain several wins as new symbols tumble in. Those cascades matter more here than in most games, because every winning symbol also feeds the charge meter sitting beside the reels.
The paytable is built on the total bet, and it climbs steeply with cluster size. Four premiums – the Cthulhu skull, dagger, ring and green skull – sit above four coloured gems, and the full ladder looks like this:
- Octopus/Cthulhu skull (purple) – 4: 2x, 5: 4x, 6: 8x, 7: 16x, 8: 32x, 9: 50x, 10+: 100x
- Dagger – 4: 1.5x, 5: 3x, 6: 6x, 7: 12x, 8: 24x, 9: 30x, 10+: 60x
- Ring/Snake – 4: 1x, 5: 2x, 6: 4x, 7: 8x, 8: 16x, 9: 20x, 10+: 40x
- Green octopus skull – 4: 0.7x, 5: 1.5x, 6: 3x, 7: 6x, 8: 12x, 9: 15x, 10+: 30x
- Purple gem – 4: 0.4x, 5: 0.6x, 6: 1x, 7: 2x, 8: 4x, 9: 4.5x, 10+: 6x
- Red gem – 4: 0.3x, 5: 0.5x, 6: 0.8x, 7: 1.6x, 8: 3.2x, 9: 4x, 10+: 5x
- Blue gem – 4: 0.2x, 5: 0.4x, 6: 0.6x, 7: 1.2x, 8: 2.4x, 9: 3x, 10+: 4x
- Green gem – 4: 0.1x, 5: 0.2x, 6: 0.3x, 7: 0.6x, 8: 1.2x, 9: 1.5x, 10+: 2x
The gaps between tiers are wide. Ten or more purple skulls pays 100x the bet, while ten or more green gems pays just 2x, so the top symbol is worth fifty times the bottom one at the same cluster size. Premium clusters of four pay between 0.7x and 2x the bet.
Wilde’s own portrait is the Multiplier Wild: it stands in for all regular symbols and doubles every win it takes part in. There’s no scatter in the usual sense; the path to the bonus runs through the charge meter instead.
The Portal and Its Effects
Every winning symbol charges the Portal, the gem-studded dial that watches over the grid. As it fills, pairs of Special Wilds are added to the reels, and winning with one of them triggers a Portal Effect.
Two effects do the clearing. Abyss removes a full row or column of symbols. Void removes every instance of one random symbol. Both feed the cascade cycle, clearing space for new symbols and fresh clusters, and both keep the charge meter climbing towards the Other World.
The order of events matters. A Special Wild has to land inside a winning cluster before its effect fires, so a grid carrying two or three of them can chain Abyss into Void inside a single cascade run – the board clears, new symbols fall, and the meter keeps counting.
Eye Marks
Certain positions on the grid carry Eye Marks. Form a win in an Eye Mark’s location and the eye opens, awarding two Special Wilds to the grid once no more wins are created. It’s a small mechanic with a large knock-on effect, since those Special Wilds are what trigger Abyss and Void.
The marks sit in fixed spots, so cluster placement genuinely matters: a win that lands across an eye pays the same as any other win but leaves two extra wilds behind for the next cascade. A cluster that misses the mark leaves nothing. It gives the 5×5 grid a spatial layer most cluster games don’t have.
The Other World Free Round
Open the Portal by winning on 42 symbols and the Other World Free Round begins. Charge it further and the round gets richer: three additional winning symbols beyond the threshold earn one extra Portal Effect, capped at seven in total.
Inside the round, one random Portal Effect fires whenever the wins dry up, and the round only ends when every effect has been played out. Each one is another chance to clear the board and set new clusters falling, so a well-stocked round can run for a long time before it settles.
Open every eye during the round and the Mega Wild is summoned: a tentacled creature that moves down the grid across cascades, creating chances with every step it takes. Wild symbols substitute for all regular symbols, so its passage can stitch together clusters that no ordinary spin would produce.
The ceiling on the whole thing is 2,000x the bet. Against very high volatility, that’s a modest cap for the effort the Portal demands.
Our Honest Verdict
Overall Rating: 8.1/10
This is a slot that makes you work for everything. The base game is a long charge towards 42 winning symbols, with Special Wilds and the occasional doubled win keeping the meter moving, and the build is the appeal: the Portal gives every cascade a purpose rather than just paying and clearing.
The Other World Free Round is the strongest thing here. Up to seven Portal Effects resolving in sequence, with the Mega Wild descending the grid if every eye opens, builds momentum that few cluster games match. The weakness is the cap. A 2,000x ceiling on very high volatility is tight for a game that demands this much patience, and Play’n GO’s own later take on this format pushed the potential considerably further.
It suits players who enjoy a long build and mechanics that stack, and who care more about how a bonus round plays out than what it can theoretically pay. Chasers of big ceilings should keep walking past this portal.
