What are the special features of Book of 99?
Book of 99 is a slot centred around its free spins feature. There are two different ways to trigger this feature, both giving a random expanding symbol for added win potential.
Free Spins
Land three wild/scatter symbols on the reels, and you will trigger the free spins feature. You will be given 10 free spins with an expanding symbol selected. Three or more wild/scatters landing during the feature will trigger a further 10 spins.
Wild Collection
Every time a Book wild/scatter symbol lands in the base game, it will be added to a trail on the left-hand side of the reels. Even symbols that trigger the feature will be added, and the trail will not reset if free spins are earned. When the trail reaches 99 symbols, the free spins feature will trigger. The free spins here are the same as the feature triggered by three scatters, 10 spins and an expanding symbol.
Expanding Symbol
Before the free spins feature takes place, an animation will play where the pages of a book open and stop on a random symbol. That symbol will then expand every time it lands on the reels as part of a winning combination, raising the chances of potential wins during this feature.
