Here are the 5 concise cons of Book of Monsters:
The game Book of Monsters by Pragmatic Play boasts an array of innovative and engaging bonus features that drive its unique gameplay experience.
Fat Symbols act as progressive multipliers, expanding in size during free spins (2x2, 3x3, 4x4, 5x5, 6x6, 7x7), awarding bonus spins and covering more of the grid for amplified winning potential. These oversized symbols move to new positions on each spin during free spins and expand progressively as matching symbols are collected.
Landing 4-7 bonus symbols triggers 5-8 free spins respectively, with Ante Bet active increasing the trigger count. During free spins, Fat Symbols collect additional matches, growing in size and awarding more bonus spins. The gamble feature allows players to strategically increase their potential winnings or play conservatively with guaranteed spins.
Players can purchase direct access to free spins at 100x the current bet, randomly triggering 4-7 scatter symbols upon purchase. This option provides a convenient way for players to gain immediate access to bonus rounds without waiting for natural triggers.
The gamble feature allows players to risk their starting conditions before free spins, upgrading the Fat Symbol to the next-highest-paying symbol or increasing the number of free spins. However, "The End" result can end the bonus immediately, potentially frustrating casual players.
