How Tome of Madness Works

Tome of Madness, developed by Play'n GO, is played on a 5x5 grid using cascading symbols. Each round begins as symbols drop into the grid. A win occurs when four or more identical symbols form a connected cluster either horizontally or vertically. After each winning combination, the winning symbols are removed and new symbols fall down, potentially creating more wins. The cascading action continues until no further winning combinations appear on the grid.

Bets in Tome of Madness can be set between £0.10 and £5.00. To adjust your wager, use the plus and minus buttons or the main bet buttons at the bottom of the game screen. The currently selected bet will be applied when you start each new round.

Wins are determined and paid according to the paytable and the game rules. All cluster wins form from adjacent symbols without gaps and may begin from any spot on the grid. Only the highest possible win per symbol combination is awarded. Winnings from all clusters and any features are added together and paid out at the end of the round.

The return to player information can be viewed in the game.

Game Features and Special Mechanics

Eye Marks and Special Wilds

Throughout the game, Eye Marks may randomly appear in different grid positions. When a winning combination is formed on an Eye Mark, the eye is opened. If no further wins occur, 2 Special Wilds are introduced to the grid.

Charging the Portal

  • Every win contributes to charging the Portal meter.
  • After 7 symbols have been won, 2 Special Wilds are added to the grid.
  • After 14 symbols have been won, 2 more Special Wilds are introduced. If a win is made using a Special Wild at this stage, the Abyss Portal Effect is triggered.
  • After 27 symbols, another 2 Special Wilds are placed on the grid. If a win occurs with a Special Wild here, the Void Portal Effect is activated.
  • If multiple charge effects are earned before previous ones activate, only the latest effect is applied.

Portal Effects Explained

  • Abyss: When triggered, Abyss removes an entire row or column starting from a winning Special Wild. These removed symbols also charge the Portal further. If Abyss removes another Special Wild, it again removes a line from that symbol.
  • Void: Void randomly selects one standard symbol type and removes all instances of it from the grid.

Other World Free Round

The Other World Free Round activates after achieving wins on 42 symbols. This bonus awards 1 free round with 3 random Portal Effects. Overcharging the Portal with additional wins adds one extra Portal Effect for every 3 more winning symbols, up to a total of 7 Portal Effects.

During the Other World Free Round, Portal Effects are triggered when no further wins are achieved in a cascade. The possible Portal Effects are:

  • Special Wilds: 4 Special Wilds are added to the grid.
  • Abyss: 4 Special Wilds are placed onto the grid. Wins with a Special Wild activate the Abyss effect as described previously.
  • Void: 4 Special Wilds are added, and wins with a Special Wild trigger the Void effect.

Throughout this feature, between 11 and 12 Eye Marks are visible. Opening all eyes by forming wins in their locations will summon the Mega Wild Cthulhu symbol. This Mega Wild moves down the grid with each cascade and disappears after reaching the bottom. The cascades persist as long as new wins are formed.

Managing Bets and Game Actions

  • Change your bet using either the main bet buttons or by clicking the plus and minus arrows to adjust in small increments.
  • Open the paytable to review symbol values and feature details.
  • To play a round, select your desired bet and click START. The outcome is determined by the symbols that land according to the current paytable.
  • If your account balance is insufficient for the chosen bet level, the game will automatically reduce your bet to the highest available amount within your balance. Bet levels are only decreased; after a win, the bet will remain at the lower amount until manually changed.

Unfinished Games

If a game round is interrupted, your game details and any bets placed are saved until you resume the game. You can continue an unfinished round from where you left off. If bets remain unsettled for 90 days in incomplete games, they will become void. In the event of a malfunction, all pays and plays will be invalidated.
