A Magical Twist on Grid Slots
It might sound like a bit of light reading at Hogwarts School of Witchcraft and Wizardry, but Pragmatic Play’s Book of Monsters is anything but ordinary. Despite the familiar-sounding title, this isn’t your typical Book of slot. Instead of the traditional expanding symbols tied to single reels, the books in this game flip open to trigger free spins and reveal randomly chosen symbols. These symbols do expand—but more in a playful, quirky style reminiscent of jiliasia Fat Rabbit rather than Book of Dead.
A Friendly Bunch of Monsters
This might be a game about monsters, but don’t expect nightmarish beasts. The creatures in Book of Monsters are more mischievous than menacing. With oversized eyes and goofy grins, they give off a Reactoonz vibe—inviting and full of playful charm. Their cave setting, glowing in a haunting blue light, becomes alive with a warm orange hue during free spins. That transformation sets the tone for excitement, and at jiliasia, the game really shines in these moments.
Cluster Pays on a 7×7 Grid
The game operates on a 7×7 grid and uses a cluster pays system. Players win by landing at least five matching symbols adjacent to each other, either vertically or horizontally. It’s a system that rewards positioning and luck in equal measure. In the base game, however, there aren’t many features—so players looking for action might prefer using the ante bet or jumping straight into the bonus buy feature offered by platforms like jiliasia.
Ante Bet and Betting Options
Players can adjust their base bets from $0.20 up to $240, accommodating both casual gamers and high rollers. When the ante bet is activated, the chance to trigger free spins increases by 7x, but your stake is also doubled. This gamble may be worth it for those looking to access the more exciting parts of the game quickly—something jiliasia players appreciate for fast-paced gameplay.

Fat Symbols and Massive Wins
In the base game, although there are no wilds, players may randomly land Fat Symbols sized 3×3 up to 7×7. These symbols can help create significant clusters, especially when they align with matching symbols around them. Low-paying symbols are designed like playing cards with suits, including the Jack of Diamonds, Queen of Clubs, King of Hearts, and Ace of Spades. Higher-paying ones include color-coded monsters—purple, green, and red—that can pay up to 5,000x for a full 49-symbol cluster.
Free Spins with a Progressive Fat Symbol
Triggering free spins requires landing 4–7 scatter symbols, which awards 5–8 spins. If the ante bet is enabled, just 3 scatters can unlock the bonus round. Before the free spins begin, a Fat Symbol is selected at random. Players can gamble to upgrade this symbol or increase their spin count—but beware: landing “The End” will forfeit the bonus round entirely.
As the round progresses, the Fat Symbol grows in size based on the number of matching symbols collected. Starting at 1×1, the symbol can level up to a massive 7×7, with extra free spins granted at each stage. This growth mechanic is unique and offers a sense of escalation rarely seen in other cluster-based games, making it a fan favorite on platforms like jiliasia.
Bonus Buy for Instant Action
For those who prefer skipping the wait, the Bonus Buy feature is available at 100x the base bet. This purchase instantly triggers the free spins round, randomly landing between 4 and 7 scatter symbols. It’s a great option for players who want to dive straight into the excitement—especially popular on fast-loading sites like jiliasia, where smooth user experience meets high-intensity slots.
A Slot That Breaks the Mold
The name Book of Monsters might mislead at first glance, suggesting a standard Book-style slot. But instead, Pragmatic Play has fused several mechanics from other popular titles into something new. It’s part cluster slot, part progressive bonus, and part symbol upgrade gamble. This cocktail of features creates a fresh and exciting take that stands out in the crowded world of grid-based slots—especially for seasoned players at jiliasia looking for something beyond the usual.
Final Thoughts
Book of Monsters is an imaginative and entertaining release from Pragmatic Play that blends elements of games like Reactoonz, Fat Rabbit, and traditional Book of slots—but delivers them in an entirely unique format. The monster theme is quirky rather than creepy, the visuals are sharp, and the bonus round brings the real thrills. Whether you’re here for the fun graphics or the hunt for massive clusters, this is a game well worth opening—especially at trusted gaming hubs like jiliasia, where it’s already gaining traction.
