As the title might suggest, the Book of Power slot game’s highest-paying symbol is the Book of Power, which triggers the free spins round. However, alongside this symbol, some of the other high-paying symbols you can land include pyramids, pharaohs, and ancient tombs. Some of the lower-paying symbols are the ones you find on the vast majority of slots and represent the playing card symbols, from 10 upwards. While these symbols can all result in a nice return, a great way to win is to land as many Book of Power symbols as you can in the base game.
