Pragmatic Play, the most popular game provider for sweepstakes casinos across the industry, has expanded its portfolio with the release of Book of Monsters, an innovative cluster-pays slot featuring supersized symbols and progressive growth mechanics.
Unlike traditional "Book of" slots that feature expanding symbols on individual reels, Book of Monsters operates on a 7x7 grid with a cluster-pays system, creating winning combinations when at least five matching symbols are adjacent horizontally or vertically.
The game's standout feature is its supersized symbols, which can randomly appear in the base game at sizes ranging from 3x3 to 7x7. This mechanic offers players the opportunity to create massive cluster wins with potential payouts of up to 5,000x the original stake.
"Book of Monsters is an exciting and visually rich slot that can deliver supersized symbols on any spin and wins of up to 5,000x," said Irina Cornides, Chief Operating Officer at Pragmatic Play.
The game's main bonus round triggers when players land four to seven scatter symbols, awarding five to eight free spins. Before the bonus begins, a random symbol is selected as the "FAT symbol," and players are presented with a gamble feature that offers the chance to:
Increase the number of free spins (up to eight total)
Upgrade the FAT symbol to a higher-paying symbol
Risk losing the bonus entirely if the gamble reveals "The End"
During free spins, the FAT symbol moves to a new position each spin. Matching symbols that appear elsewhere on the grid are collected in a meter, allowing the FAT symbol to grow progressively from its initial 1x1 size up to a massive 7x7, with each growth stage awarding 1-3 additional spins.
Book of Monsters joins Pragmatic Play's extensive slot catalog, following recent releases like Big Bass Return to the Races and 5 Lions Megaways 2. The company also recently expanded its offerings with two slots from Fat Panda, an exclusive new studio: Lucky Tiger and Lucky Mouse.
As the preferred game provider for sweepstakes casinos, Pragmatic Play continues to innovate with high-volatility titles featuring unique mechanics that appeal to players seeking engaging gameplay and significant win potential.
The game offers betting options from 20 cents to $240, with an optional ante bet that doubles the stake while making free spins seven times more likely to trigger. Players can also buy directly into the bonus round for 100 times their base bet.
