How to play Book of the Priestess

Descend into the priestess's sealed sanctum, where every carved inscription hides a fragment of forbidden knowledge. Your task is to gather the Books she left behind: three or more anywhere on the reels open the chamber for 10 Free Spins. One symbol is chosen to stretch across its entire reel when it forms a win. Each Book you collect during the round fills the Ancient Mask by one step, and once seven have been gathered, the mask grants five more spins and marks a second symbol for expansion, a process that can repeat until all nine symbols have been chosen. Book of the Priestess is a medium-high volatility, fixed-payline slot from Evoplay. Its 5x3 grid pays when matching symbols land from the leftmost reel. The Book symbol acts as a scatter and a wild, substituting for all paying symbols and triggering the Free Spins round. A full run of five priestess symbols can pay up to 500x your stake. Here is how you play.
