Book of Monsters is a new cluster pays online slot from Pragmatic Play where landing four to seven scatters triggers the bonus game, with five to eight free spins.
Symbols measuring up to 7x7 can randomly appear on any spin.
In the free spins round, a random symbol is chosen as the FAT symbol and a gamble feature offers the chance to increase the number of free spins and upgrade the FAT symbol to the next-highest-paying symbol.
During the feature, the FAT symbol moves to a new position on each spin. Every landed symbol matching the FAT symbol is collected in a meter. As these accumulate, the FAT symbol can increase in size to 2x2 up to 7x7, awarding 1-3 extra spins each time it grows.
Irina Cornides, chief operating officer at Pragmatic Play, said: “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.”
