Rich Wilde and the Tome of Madness

Rich Wilde and the Tome of Madness drops the traditional paylines entirely, replacing them with a 5x5 cluster-pays grid where 4 or more matching symbols connected horizontally or vertically constitute a win. Play'n GO built the game around an H.P. Lovecraft-inspired Cthulhu setting, a cascading avalanche mechanic, and a Portal Meter system that charges with each consecutive win and unlocks progressively stronger wild effects. Very high volatility, 96.59% RTP, 2,000x maximum win. Available on desktop and mobile at Wild.io.

What is Rich Wilde and the Tome of Madness?

Rich Wilde and the Tome of Madness is a 5x5 video slot from Play'n GO with a 96.59% RTP, very high volatility, cluster pays (4+ matching symbols), and a maximum win of 2,000x your bet. Its standout mechanic is the Portal Meter, a charge system where each avalanche win fills the meter and unlocks wild placement effects, culminating in the Other World free round with a 3x3 Cthulhu Mega Wild.

Play'n GO released Tome of Madness in June 2019 as a departure from the Dead series into the Cthulhu Mythos. The 5x5 grid operates on cluster pays: symbols win when 4 or more of the same type connect in any direction, and winning symbols disappear in an avalanche, new ones drop down to fill the gaps, potentially creating chain reactions. The Rich Wilde character appears as a Multiplier Wild that doubles any win it contributes to. The Necronomicon Book Wild triggers portal effects. The Portal Meter fills with each consecutive win in a cascade chain and, when fully charged, unleashes increasingly powerful wild events. The Other World free round features the 3x3 Cthulhu Mega Wild, a symbol that covers 9 positions simultaneously.

Who will enjoy this game the most?

You will probably enjoy this game if you like:

• Cluster-pays slot players who want an avalanche mechanic rather than fixed paylines, wins chain from cascades rather than line counts
• Rich Wilde series fans who want the character in a Lovecraftian setting rather than an Egyptian or archaeology backdrop
• Very-High-volatility players chasing chain-cascade wins through the Portal Meter progression
• Crypto casino players who want a 5x5 grid with progressive wild mechanics and a thematically distinct fantasy horror setting
• Players who enjoy feature-heavy games with multiple wild types, Multiplier Wilds, Book Wilds, Electric Wilds, Eye Marks, and a 3x3 Mega Wild each interact differently

How To Play Rich Wilde and the Tome of Madness Slot - Step By Step

Head to Wild.io and create a free account to start playing Rich Wilde and the Tome of Madness.

1. Set your bet and spin the 5x5 grid, wins form when 4 or more identical symbols connect horizontally or vertically, not through paylines.
2. Winning symbols disappear and new ones avalanche down to fill the gaps, any new winning clusters formed by the avalanche pay out before the cascade ends.
3. Each win in a cascade chain charges the Portal Meter, watch the meter fill with the Necronomicon Book symbol as each consecutive avalanche step adds charges.
4. When the Portal Meter fills, it triggers a wild placement effect: the specific effect depends on how many charges have accumulated, higher charges unlock stronger wild outputs.
5. Accumulate Eye Mark charges during base play to earn additional wild placements that trigger independently of the Portal Meter.
6. The Other World free round launches when the Portal Meter reaches its maximum, the 3x3 Cthulhu Mega Wild fills 9 positions and is the primary path to the highest single-round payouts.

Rich Wilde and the Tome of Madness Slot Theme & Graphics

Tome of Madness is built on H.P. Lovecraft's Cthulhu Mythos, specifically the concept of forbidden knowledge and the cosmic horror of the Necronomicon. Rich Wilde, Play'n GO's recurring archaeologist protagonist, appears here not as an Egyptian explorer but as a researcher who has opened a portal to the Other World. The visual palette is dark and desaturated with tentacle motifs, cthulhu medallion imagery, and eldritch artefacts, daggers, golden rings, and skull icons rendered in a deep jewel-tone style.

Play'n GO designed the 5x5 grid to feel more compact and contained than a wide reel set, which suits the Lovecraftian theme of everything converging on a single point of madness. The Portal Meter animation uses a swirling portal visual that builds in intensity as charges accumulate, giving a strong visual cue to the mechanic state. On mobile the grid is touch-responsive and the cascade animations are fluid without impacting load speed. The audio uses atonal strings and low percussion that fits the horror tone without being distracting during extended sessions.

Rich Wilde and the Tome of Madness Slot Symbols & Paytables

Tome of Madness uses an 8-symbol paytable split into four gemstone low-value symbols and four Lovecraftian artefact premiums, plus three types of wild symbols and two special indicators. Wins form from clusters of 4 or more rather than lines, so the payout figures are structured around cluster sizes of 4, 5, 6, 7, 8, 9, and 10 or more. The larger the cluster, the larger the multiplier on your stake.

Low Value Symbols

The four gemstone symbols are purple, red, blue, and green coloured gems, stylised with an eldritch glow effect consistent with the Cthulhu aesthetic. These are the low-value cluster symbols and they award 2x to 6x your bet for clusters of 10 or more matching gems. Clusters of 4 are the minimum for a payout and pay at the lower end of the scale. Because the 5x5 grid has 25 positions, gemstones appear in large quantities and form the majority of base-game cluster wins. They are the fuel for the Portal Meter's charge chain rather than large individual win contributors.

• Purple Gemstone, lowest value cluster symbol
• Red Gemstone, low value cluster symbol
• Blue Gemstone, low value cluster symbol
• Green Gemstone, low value cluster symbol; all pay 2x-6x for 10+ in a cluster

High Value Symbols

The four Lovecraftian artefact symbols are the Cthulhu Amulet, the Dagger, the Golden Ring, and the Cthulhu Mask Medallion, rendered as ornate carved objects with deep gold and teal colouring. These award 30x to 100x your bet for clusters of 10 or more. The Cthulhu Mask Medallion is the top-paying symbol and can pay 100x for the maximum cluster size. In a cascading grid where 4+ matching symbols in any direction qualify, high-value artefact clusters form less frequently but produce proportionally larger wins when they do, and when the Rich Wilde Multiplier Wild contributes to one, the 2x multiplier doubles the already elevated payout.

• Cthulhu Amulet, high-value symbol
• Dagger, high-value symbol
• Golden Ring, high-value symbol
• Cthulhu Mask Medallion, top-paying symbol; all pay 30x-100x for 10+ in a cluster

Special Symbols

Three wild types operate in Tome of Madness. The Necronomicon Book Wild is a standard substituting wild with a portal effect trigger potential, it substitutes for all paying symbols and, when activated by the Portal Meter, generates additional wilds. Rich Wilde himself is the Multiplier Wild: he substitutes like the Book Wild but doubles the value of any winning cluster he contributes to, making him the highest-impact single symbol in the game. The Eye Marks are not traditional symbols, they are charge indicators that accumulate on the grid during play and trigger additional wild placements independently of the main Portal Meter system. The 3x3 Cthulhu Gargantoon Mega Wild appears exclusively in the Other World free round and occupies 9 grid positions simultaneously.

• Necronomicon Book Wild, standard wild with portal effect trigger potential; substitutes all paying symbols
• Rich Wilde Multiplier Wild, doubles wins it contributes to
• Eye Marks, trigger additional wild placements
• Gargantoon Mega Symbol, fills 3x3 area during Other World free round

Rich Wilde and the Tome of Madness Bonus Feature & Special Features

Cascading Avalanche

Tome of Madness uses a cascading avalanche mechanic rather than a standard spin-and-stop reel set. When 4 or more matching symbols form a cluster anywhere on the 5x5 grid, those symbols are removed and new symbols fall down from above to fill the empty positions. If the newly settled symbols form new winning clusters, those also pay out and cascade again. A single spin can produce multiple consecutive avalanche wins, the cascade chain continues until no new winning clusters form. Each avalanche step in the chain charges the Portal Meter. Longer chains both pay more in total and push the Portal Meter further toward its wild-effect thresholds, meaning a good cascade sequence rewards in two ways simultaneously.

Portal Meter and Wild Effects

The Portal Meter sits alongside the grid and charges with each win in an avalanche cascade chain. When the meter reaches specific charge thresholds, it unlocks wild-placement effects of escalating power: lower charges place a small number of additional wilds on the grid, higher charges place more wilds or stronger wild types including the Rich Wilde Multiplier Wild. The meter resets after each spin that does not continue the cascade chain. The Portal Meter system means sustained cascade chains have compounding benefits, each step both pays a cluster win and brings the meter closer to a wild activation threshold. The highest-charge unlocks include effects that place multiple wilds simultaneously, which can then contribute to new cluster formations in the continued cascade.

Other World Free Round

The Other World free round is Tome of Madness's primary bonus event. It activates when the Portal Meter reaches its maximum charge level, which requires a sustained cascade chain that fills the meter completely. During the Other World round, the 3x3 Cthulhu Mega Wild is placed on the grid, occupying 9 positions simultaneously. The Mega Wild substitutes for all paying symbols at every position it covers, which means it can contribute to multiple different cluster formations at once. The Rich Wilde Multiplier Wild also activates during this round, doubling wins it contributes to. The combination of the 3x3 Mega Wild covering 9 of the 25 grid positions and the doubling Multiplier Wild is the main mechanism behind the 2,000x maximum win in this very-high-volatility format.
