How the Game Plays

Book of Monsters transports players to a mysterious monster-filled dimension where quirky creatures can randomly balloon up to massive sizes. The game uses a 7×7 grid with cluster pays, meaning you need at least 5 matching symbols touching each other vertically or horizontally to win. Playful monster symbols land alongside card-rank symbols (jack, queen, king, etc.). During base gameplay, fat symbols can appear at random, expanding to create larger winning opportunities. The magical book hovers above the grid, ready to trigger the bonus round.

Free Spins Feature Explained

When the book triggers free spins, one paying symbol is randomly selected as the Fat Symbol for the entire bonus. Players then face a gamble choice: they can either collect their starting conditions and begin the free spins, or gamble to upgrade the Fat Symbol to a higher-paying one or increase the number of free spins. If the book reveals "The End" during a gamble, the bonus ends immediately. Successful gamblers can earn up to 8 free spins, with fat symbols expanding up to 7×7 during the feature, creating massive winning clusters.
