The Allure of the ‘Book of’ Mechanism
It all revolves around the Book icon. It functions as both a scatter symbol and a joker. Hit three or more Book symbols anywhere on the reel grid, and you activate the free spins feature. Here, the game randomly selects one regular icon to become enhanced. Each time that symbol appears during your free spins, it expands to fill its full reel. This can generate some huge rewards. The feature is wonderfully straightforward. There are no complexities or elements, just the pure possibility for a single spin to blow up on the screen and change your session completely.
