Book of Truth slot review
Book of Truth is TrueLab's take on the classic Egyptian "book" slot, released in July 2021. It follows the familiar formula — a book that is both wild and scatter, free spins with an expanding symbol — but adds a twist: five books unlock True Free Spins, in which every symbol expands.
