Book of Aztec Bonus Buy

Book of Aztec Bonus Buy retains the 5×3 structure and 10 fixed paylines of the original game while adding direct access to its bonus feature. The Book symbol acts as both Wild and Scatter, with three or more Books activating 10 Bonus Spins.

At the start of the feature, one symbol is selected at random as the expanding symbol. It expands during the Bonus Spins and pays across the active lines, while additional Book symbols can award further spins. The Bonus Buy option provides an alternative way to enter the bonus feature without waiting for its normal trigger.
