Book of Monsters Design and Gameplay

Book of Monsters by Pragmatic Play takes players to a dark, cartoon-style world filled with mystery, monsters, and an arcane atmosphere. As far as gameplay goes, there's a 7x7 grid where symbols can appear in different sizes. If five or more symbols connect horizontally or vertically, a winning combination is created.

FAT symbols appear in the base game, with sizes from 3x3 to 7x7, making it easy to connect large clusters. The fantasy setting of the game combines well with the monster artwork to create an eerie atmosphere, with apt sound effects and animated symbols. As with most crypto casino slots, the Book of Monsters online slot has a free spins feature where random symbols can become FAT.

Like many other Bitcoin slot machines, the Book of Monsters casino game uses the cluster pays mechanic to form paying combinations. There are seven regular paying symbols in the game. Here's the full breakdown:

• Red Monster — Pays up to 5,000× the total bet for a 49-symbol cluster.
• Green Monster — Pays up to 1,500× the total bet for a 49-symbol cluster.
• Purple Monster — Pays up to 1,000× the total bet for a 49-symbol cluster.
• Ace (A) — Pays according to the cluster-size paytable, with larger connected groups producing higher payouts.
• King (K) — Pays according to the cluster-size paytable, with larger connected groups producing higher payouts.
• Queen (Q) — Pays according to the cluster-size paytable, with larger connected groups producing higher payouts.
• Jack (J) — Pays according to the cluster-size paytable, with larger connected groups producing higher payouts.
• Bonus — Pays separately and triggers free spins when at least four land.
• FAT Symbol — A bigger version of a randomly selected symbol that can reach a format from 3×3 to 7×7.
