How the Game Plays

Rich Wilde and the Tome of Madness is a dark, Lovecraftian-inspired grid slot that follows the famous explorer as he uncovers the secrets of the Cthulhu Mythos. Played on a 5x5 grid, the game utilizes a cluster pays mechanic where wins are formed by landing groups of four or more matching symbols touching horizontally or vertically. Each win triggers a cascade, where winning symbols vanish to be replaced by new ones falling from above, allowing for multiple consecutive wins from a single paid spin.

Portal Features Explained

The Portal Meter to the left of the grid is central to the gameplay. It charges whenever symbols are part of a winning cluster. Reaching specific thresholds—7, 14, 27, and 42 symbols—triggers unique modifiers. These include the "Abyss" and "Void" effects, which remove entire rows, columns, or specific symbol types to help clear the board and continue the win streak. Eye Marks also appear randomly; winning on these spots adds Special Wilds to the grid once the current cascade sequence ends.

Other World Free Round

The primary goal is to charge the Portal with 42 symbols, which triggers the Other World Free Round. Players receive a single free spin with several guaranteed Portal Effects. If the meter was overcharged during the trigger, additional effects are added. During this bonus, opening all Eye Marks by forming wins over them summons the Mega Wild Cthulhu. This massive 2x2 symbol moves down the grid with each cascade, acting as a wild to help complete large clusters before eventually disappearing from the bottom of the board.
