The symbols in Rich Wilde and the Tome of Madness do much more than determine cluster payouts. Every symbol contributes to the game's distinctive Portal system, where cascading wins charge powerful features that gradually unlock throughout gameplay. Inspired by ancient relics and supernatural mysteries, the symbol collection combines valuable artefacts, colourful gems and several unique Wilds that influence how the grid develops. (Play'n GO)
Unlike traditional online slots with paylines, Rich Wilde and the Tome of Madness uses a 5x5 cluster grid. Four or more matching symbols connected horizontally or vertically form a winning cluster, after which the symbols disappear and new ones cascade into place. Every winning symbol also contributes towards charging the Portal meter, making each symbol important beyond its individual payout.
As with all slot games available through Slingo, every spin is determined independently by random outcomes.

Each category plays a different role, with some symbols paying through clusters while others activate bonus mechanics.
Tome of Madness Special Wild
The Book of Madness, also known as the Tome of Madness, serves as the game's primary Special Wild.
Its role is to substitute for regular symbols, helping complete winning clusters across the grid. Because the game uses cluster pays rather than paylines, the Special Wild can connect several groups of matching symbols that would otherwise remain separate.
The Special Wild appears during both the base game and bonus features, making it one of the most frequently encountered special symbols.
Rich Wilde Multiplier Wild
Rich Wilde himself also appears as a Wild symbol, but with an additional benefit.
When Rich Wilde contributes to a winning cluster, he acts as a Multiplier Wild, doubling the value of that cluster while substituting for premium symbols. This makes him particularly valuable when he lands as part of larger premium symbol combinations.
Unlike the standard Special Wild, Rich Wilde enhances qualifying cluster values through its built-in multiplier effect.
Mega Wild
The largest Wild in the game appears only during the Other World feature.
Known as the Mega Wild, this symbol represents the mysterious Cthulhu creature revealed once all Eye Marks are opened during the bonus round.
The Mega Wild:
- Covers multiple positions on the grid
- Acts as an oversized Wild symbol
- Continues moving through cascading sequences
- Helps create larger connected clusters
Because it is exclusive to the bonus feature, players will only encounter the Mega Wild after progressing through the Portal mechanics.
Premium Artefact Symbols
The highest-paying regular symbols reflect Rich Wilde's archaeological expedition and the game's supernatural setting.
These premium artefacts include:
|
Symbol |
Theme |
|
Cthulhu Skull |
Ancient relic |
|
Octopus Pendant |
Occult artefact |
|
Ceremonial Dagger |
Explorer's discovery |
|
Gem Ring |
Mystical treasure |
These symbols award the highest regular cluster values when four or more connect on the grid. Larger clusters naturally provide higher returns than smaller ones, although every outcome remains random. (Casinolandia)
Gem Symbols
Supporting the premium artefacts are four lower-value gemstone symbols.
These consist of:
- Purple Gem
- Red Gem
- Blue Gem
- Green Gem
Although they carry lower values than the artefacts, gem symbols appear more frequently and often contribute to longer cascading sequences because of their higher occurrence rate. (casinofever.ca)
Since every winning cluster charges the Portal meter regardless of symbol value, gem symbols still play an important role in feature progression.
Eye Marks Explained
Eye Marks are not traditional pay symbols.
Instead, they appear on selected grid positions during gameplay.
Whenever a winning cluster passes through one of these marked spaces:
- The Eye Mark opens.
- Two Special Wilds are awarded.
- Additional feature opportunities become available.
During the Other World feature, opening every Eye Mark eventually reveals the Mega Wild, making these positions particularly important as the bonus develops.
Portal Meter
Although technically not a reel symbol, the Portal meter interacts directly with every winning symbol on the grid.
Each symbol contributing to a winning cluster charges the meter.
As the Portal fills, it unlocks progressively stronger effects, including:
|
Portal Level |
Effect |
|
Early Charge |
Special Wilds added |
|
Mid Charge |
Abyss effect becomes available |
|
Higher Charge |
Void effect activates |
|
Full Charge |
Other World bonus begins |
Rather than paying directly, the Portal creates opportunities for additional symbol transformations and cascading sequences. (Play'n GO)
How the Symbols Work Together
One of the game's strengths is how every symbol contributes to multiple mechanics.
A typical feature sequence may include:
- Premium artefacts forming a cluster.
- Cascading gems creating another cluster.
- Portal meter charging.
- Eye Marks opening.
- Special Wilds appearing.
- Rich Wilde multiplying a cluster.
- Portal effects transforming the grid.
Instead of functioning independently, the symbols continually interact as the Portal becomes more powerful.

Final Thoughts
The symbol collection in Rich Wilde and the Tome of Madness combines atmospheric artwork with practical gameplay functions. Premium artefacts and colourful gems build winning clusters, while the Tome of Madness Wild, Rich Wilde Multiplier Wild and Mega Wild introduce additional ways to enhance the grid during feature sequences.
Meanwhile, Eye Marks and the Portal system ensure that every successful cluster contributes towards unlocking new mechanics rather than simply awarding payouts. This interconnected design helps distinguish the game from many other online slots and creates an evolving experience throughout each session. As always, every spin remains random, making Rich Wilde and the Tome of Madness a game of chance available through Slingo.
