• Ante Bet: activating this feature doubles the bet cost, but the probability of triggering free spins increases sevenfold. However, with Ante Bet active, the option to directly purchase the bonus is disabled.

The slot offers a betting range between €0.20 and €240, with an RTP of 96.5% in all modes. Given the stable RTP, one might have expected different volatility management, but the choice falls on a high variance structure, rewarding occasional big wins more.

Without traditional paylines, the slot relies on the cascading mechanic, removing winning combinations and dropping new symbols to fill empty spaces.

Jackpot and maximum wins

The maximum possible win is 5000x the bet. Reaching this limit immediately ends the round, awarding the maximum allowed amount.

Author's notes

In a sector crowded with slots featuring mysterious books and fantastic creatures, Book of Monsters attempts to carve out its space with an idea that borrows concepts from multiple directions. While the title suggests inspiration from classics like Book of Dead, the gameplay departs, adopting an approach closer to Fat Rabbit. The result is an experience that can attract those seeking progressive dynamics and long-term challenges. The lack of features in the standard game might be a weakness, but the management of the Fat Symbol progression adds an interesting strategic element. The alternation between symbol growth and betting to improve one's position introduces a risk variable, leaving room for different choices for each player.
