What Is Tome of Madness?

Tome of Madness is an online slot developed by Play’n GO, featuring a 5×5 grid and cascading symbols. Players join the character Rich Wilde on his mystical adventure, forming clusters of winning symbols to unlock a range of engaging features.

How Are Wins Achieved in Tome of Madness?

Wins are formed by landing groups of four or more matching symbols that connect horizontally or vertically on the grid. When a cluster is created, the symbols involved disappear, letting new symbols drop into the vacant spaces. This process, known as a cascade, continues until there are no more possible winning combinations.

What Are Eye Marks and How Do They Work?

Eye Marks can appear randomly on the grid. Whenever a win occurs in a position marked by an Eye Mark, the eye opens. Once no further wins are possible, two SPECIAL WILDS are added to the grid, potentially leading to additional rewards.

What Is the Portal and How Does It Charge?

Each win contributes to charging the Portal, a central mechanic in Tome of Madness. As you collect winning symbols, certain thresholds trigger additional features:

  • After 7 winning symbols: 2 SPECIAL WILDS are added.
  • After 14 winning symbols: 2 more SPECIAL WILDS are added.
  • After 27 winning symbols: 2 more SPECIAL WILDS are added.

Triggering a win with a SPECIAL WILD at 14 and 27 symbols also activates the ABYSS or VOID Portal Effects, respectively. Only the most recent charge effect is awarded if multiple are earned before earlier effects can take place.

What Are the ABYSS and VOID Portal Effects?

These effects provide extra opportunities for wins:

  • ABYSS: Removes a row or column from the position of a winning SPECIAL WILD, adding these removed symbols to further charge the Portal. If another SPECIAL WILD is removed, this effect continues from that symbol.
  • VOID: Randomly selects one regular symbol and removes all instances of it from the grid.

What Is the Other World Free Round and How Is It Triggered?

The Other World Free Round is activated after a player collects wins from 42 symbols in a single round. One free round is awarded, featuring three random Portal Effects. If more than 42 winning symbols are collected, an additional Portal Effect is granted for every three extra symbols, up to a maximum of seven Portal Effects.

How Do Portal Effects Operate During the Free Round?

During the Other World Free Round, a Portal Effect is triggered whenever no further wins can be made. The possible effects include:

  • SPECIAL WILDS: Four SPECIAL WILDS are placed on the grid.
  • ABYSS: Four SPECIAL WILDS are added. If a win occurs with any of these, the ABYSS effect is triggered.
  • VOID: Four SPECIAL WILDS are added. A win with any of these triggers the VOID effect.

What Happens with Eye Marks in the Free Round?

In the Other World Free Round, there are 11 or 12 Eye Marks visible. Each is opened by landing a win on its position. If all eyes are opened, the MEGA WILD Cthulhu symbol enters the grid and descends with each cascade until it disappears. The round continues to cascade until no more winning combinations are possible.

How Are Bets Managed?

The minimum bet per spin is £0.10 and the maximum bet is £5.00. Bets can be adjusted using the plus and minus buttons or by selecting one of the available bet buttons. The bet amount applies to all subsequent spins unless changed. Bets cannot be altered during an active round or during free rounds. Free round features use the same bet as the triggering spin.

How Are Winnings Determined and Paid Out?

Cluster wins are calculated based on adjacent matching symbols, as detailed in the paytable and game rules. If multiple clusters win in a single round, all winnings are combined and added together. Wins from features, bonus rounds, or any applicable scatter symbols are also added to the total. All winnings are paid at the end of each round. Only the highest win for each cluster is paid, and all clusters must be directly connected horizontally or vertically, without gaps. Winning sequences can start anywhere on the grid.

Where Can You Find the RTP?

The Return to Player (RTP) value for Tome of Madness is displayed within the game.

How Does the Game Handle Disruptions and Unfinished Rounds?

If a game round is interrupted, all bets and game information are saved so you can resume from where you left off upon reopening the game. Unresolved bets on incomplete game rounds will be voided after 90 days of inactivity. Any malfunction will void all pays and plays.

What Are the Available Actions in the Game?

  • Changing Your Bet: Use the plus and minus buttons or the preset bet amounts to select your preferred stake.
  • Paytable: Click to display or hide the paytable details.
  • Start / Spacebar: Begin a round using the currently chosen bet.
  • Auto Adjust Bet: If your balance is insufficient for the selected bet, the game will lower your bet to the highest available amount you can afford. The bet will not increase automatically after wins.
