Enter the eerie world of Book of Monsters, a thrilling cluster-pay slot by Pragmatic Play. Played on a 7x7 grid, this high-volatility game immerses players in a mysterious cave filled with quirky monsters and glowing specters. Featuring Fat Symbols, Free Spins, and a unique gamble feature, the gameplay offers dynamic and rewarding experiences. With an RTP of 96.5% and a max win of 5,000x your bet, Book of Monsters combines spine-chilling excitement with captivating visuals for an unforgettable gaming adventure.
Book of Monsters does not have the usual paylines but requires matching symbols in a cluster (a.k.a. cluster pays) instead. The game has several features including Bonus Bet, Buy Feature, Cluster Pays, Collect Symbols, Colossal Symbols, Extra Spins, Free Spins Gamble, Level Up, Special Symbols, and more. Book of Monsters also has a free spins bonus round and this is usually where you can win the big money.
The RTP (Return to Player) for Book of Monsters slot is 96.5%. This payback is good and considered to be about average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €96.5. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 5000x your total bet which is pretty high and gives you the chance to win quite big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
Book of Monsters is a volatile slot, and Pragmatic Play rates the volatility High (4/5). Volatility, in the context of slot games, refers to how often and how much a slot game pays out. Book of Monsters is designed to appeal to those who enjoy the adrenaline rush of substantial winnings that low volatility slots can't deliver, and are willing to accept the inherent risks of less frequent payouts.
