Tome of Madness

Play’n GO presents Tome of Madness, a video slot featuring a 5×5 grid that operates on a cluster pays mechanic, where wins are formed by four or more adjacent matching symbols either horizontally or vertically. The game immerses players in a Lovecraftian horror theme, as Rich Wilde explores the dark Cult of Cthulhu and the enigmatic secrets of the Tome. It incorporates cascading reels, allowing winning clusters to vanish and new symbols to fall into place, which can lead to successive wins. A Portal Meter located next to the grid fills up with each symbol cleared from a winning combination, and reaching certain thresholds of 7, 14, 27, and 42 symbols activates various features. At the lower thresholds, special wilds are introduced, while at 14, a feature named Abyss can eliminate entire rows or columns. When 27 symbols are cleared, a Void effect can wipe out symbols across the entire grid, and reaching 42 symbols activates the Other World Free Round. This bonus round starts with 11 or 12 “Eye Marks” placed on the grid; each win that lands on an Eye Mark reveals it, and uncovering all Eyes brings forth a Mega Wild Cthulhu, a large wild that descends with each cascade. Rich Wilde serves as a Multiplier Wild, enhancing wins by x2, and the Tome symbol acts as a Special Wild, substituting for standard symbols. Unlike traditional free spins triggered by scatters, the Other World Free Round takes their place and includes various modifier effects. In many regions, there is no confirmed option for a bonus buy, but the bonus round remains a significant attraction in markets where such features are available.
