Book of the Priestess Bonus Buy

Book of the Priestess Bonus Buy by Evoplay is a video slot with 5 reels, 3 rows, and 10 fixed paylines. The game is thematically based on the Aztec civilization, featuring colorful priestesses, golden artifacts, and a mystical book that forms the heart of the bonus features. The book symbol acts as both a Wild (to replace other symbols) and a Scatter (to activate bonuses). When three or more Scatter/Wild books appear on the reels, this activates the Free Spins round in which you receive 10 free spins.

Before the Free Spins begin, a regular symbol is randomly selected as the Expanding Symbol. When enough of this symbol appear during the Free Spins, it expands to fill an entire reel, providing extra chances for wins across the paylines. During the Free Spins, there is also the “Ancient Mask” progress bar: each scatter symbol that appears in this round counts down the bar from seven to zero. Upon reaching zero, you receive five extra free spins and an additional Expanding Symbol.

The Free Spins feature can be retriggered if more Scatter symbols appear and the progress bar fills up again. The Bonus Buy feature allows players to purchase direct access to the Free Spins, without waiting for the Scatter symbols to accumulate in the base game. The combination of Expanding Symbols, progression through the Ancient Mask bar, and the possibility of Bonus Buy gives players control and the chance for larger wins within the game.

You can try it for free in demo mode or play it for real money.
