Tome of Madness
Tome of Madness is a slot game inspired by Lovecraftian themes, immersing players in mysterious visuals and eerie sounds as they join explorer Rich Wilde on a quest. The game features unique cascading mechanics and special symbols that unlock portals and powerful bonus features.
How Tome of Madness Works
Tome of Madness, designed by Play'n GO, is a cascading slot game featuring a 5x5 grid. The reels are filled with symbols that drop down, and the aim is to create winning clusters of 4 or more matching symbols that are connected horizontally or vertically. Once a winning cluster is formed, those symbols are removed, and new ones fall from above to fill the gaps. This cascading process continues until no new wins are possible in a game round.
Cluster wins pay only for adjacent symbol combinations, and multiple clusters formed in a single round will have their payouts added together. All winnings from features and the bonus round are combined with cluster wins. At the end of each round, the total winnings are awarded.
All winning combinations must consist of connected symbols with no gaps, and they may begin from any position on the grid. Only the highest win for each symbol combination is paid.

Game Features and Special Effects
Eye Marks and Special Wilds
Throughout the game, Eye Marks can randomly appear in different grid locations. When you form a winning combination in a position marked by an Eye Mark, that eye is opened. After all cascades have ended in a round, 2 Special Wild symbols are added to the grid.
Portal Charging and Effects
Winning clusters also charge the Portal. As you win symbols during a round, reaching specific milestones triggers additional features:
- After 7 symbols are part of wins: 2 Special Wilds are added.
- After 14 symbols are won: 2 Special Wilds are added. If a Special Wild is then part of a win, the Abyss Portal Effect is activated.
- After 27 symbols are won: 2 more Special Wilds are added. If a Special Wild is part of a win, the Void Portal Effect is triggered.
If multiple charging thresholds are passed before earlier effects have played out, only the last effect achieved is activated.
Portal Effects Explained
- Abyss: Removes all symbols in a row or column originating from the triggered Special Wild. Any symbols removed in this way help further charge the Portal. If this also removes another Special Wild, the removal repeats from that symbol.
- Void: Randomly selects one regular symbol on the grid and removes all matching symbols from view.
Other World Free Round
If you collect wins from 42 symbols in a single game round, the Other World Free Round is triggered. This awards one free round, accompanied by three random Portal Effects. Collecting more wins while overcharging the Portal adds an extra Portal Effect for every three additional winning symbols, up to a maximum of seven Portal Effects for the round.
During the Other World Free Round, one Portal Effect activates whenever no further wins occur, in sequence. The possible Portal Effects in this round are:
- Special Wilds: 4 Special Wilds are added to the grid.
- Abyss: 4 Special Wilds are added. If any Special Wild is involved in a win, the Abyss effect is triggered.
- Void: 4 Special Wilds are added. If any Special Wild is involved in a win, the Void effect is triggered.
During this round, 11 or 12 Eye Marks appear. Open eyes by winning on their positions. If all eyes are opened in this round, a Mega Wild Cthulhu symbol appears, cascading down the grid until it disappears. Play continues until no further wins are possible.
