What Will You Play Next
Pragmatic Play’s Book of Monsters may sound like something straight out of a wizarding library, but instead of the usual expanding-symbol mechanics seen in many “Book of” slots, this game takes a fresh approach with a cluster-paying system.

About the slot
While it still features a mysterious book that reveals free spins and special symbols, its gameplay leans more toward a Fat Rabbit-style progression rather than a Book of Dead classic.
Visually, Book of Monsters presents a cavernous setting inhabited by quirky, mischievous-looking monsters rather than terrifying beasts. The background glows an eerie blue, shifting to a warm orange when the free spins feature is triggered—a transition players will want to see often since the most exciting action happens in the bonus round.
Gameplay
The game plays on a 7x7 grid with a cluster pays system, requiring at least five matching symbols to connect horizontally or vertically for a win. With high volatility and an RTP of up to 96.5%, Book of Monsters offers a betting range from $0.20 to $240 per spin. Activating the Ante Bet doubles the wager but increases the chances of triggering free spins by seven times. The base game is relatively simple, occasionally featuring “Fat Symbols” of various sizes (3x3 to 7x7) that randomly appear on the reels to enhance wins.
Paytable
The paytable consists of card suit symbols (Jack, Queen, King, Ace) as low-paying icons, followed by three distinct monsters—purple, green, and red—as premium symbols. Winning clusters can pay anywhere from 0.2x to 5,000x, depending on the size. Notably, the game lacks wild symbols, relying instead on the Fat Symbols and bonus rounds to generate big wins.

Free Spins & Fat Symbol Mechanics
Landing 4 to 7 scatters in the base game triggers 5 to 8 free spins, respectively. If the Ante Bet is active, players can enter the feature with as few as 3 scatters. Before the round begins, a random pay symbol is selected as the special “Fat Symbol.” Players have the option to gamble for a better Fat Symbol or more free spins, though failing this gamble could result in losing the feature altogether.
During free spins, the Fat Symbol starts as a 1x1 symbol that moves around the grid each spin. Collecting more of the chosen symbol gradually expands it up to a massive 7x7, unlocking additional free spins along the way. This progressive feature adds a level of excitement and strategic gameplay to the bonus round.
Bonus Buy Option
For players who prefer instant access to the action, Book of Monsters offers a Bonus Buy feature for 100x the current bet. Purchasing the bonus guarantees a random number of scatters (4 to 7), leading straight to the free spins round.
Book of Monsters reimagines the “Book of” genre with cluster pays and an engaging Fat Symbol mechanic. While the base game feels a bit slow, the progressive bonus round makes up for it, offering players a thrilling chase for larger symbols and bigger payouts. Fans of Reactoonz or Fat Rabbit will likely appreciate the unique gameplay twist.
