Book of 99

Relaxgaming's Book of 99 features a video slots game with 5 reels and 3 rows, offering 10 fixed paylines. The game is inspired by ancient Greek mythology, showcasing imagery of gods, heroes, and legendary warriors that enhance its thematic experience. Players can activate the Free Spins feature in two ways: by landing three or more Book symbols in the base game or by collecting 99 Book wild/scatter symbols over several spins to fill a collection meter. Once Free Spins commence, a regular symbol is randomly selected to become the special expanding symbol. This expanding symbol can cover entire reels during Free Spins and pays out on all 10 paylines, even if the winning symbols are not adjacent. The Book symbol functions as both a Wild and a Scatter, replacing regular symbols and initiating bonus features. Additionally, Free Spins can be retriggered by landing more Book symbols during the feature, which grants extra Free Spins. The game offers a maximum win potential of up to 5,000 times the player's bet when the highest-paying symbol is selected as the expanding symbol. The standard version of Book of 99 does not include a bonus buy feature.
