Slots with the "Book" function: why it is so popular
Introduction
The "Book" function has become the benchmark for hundreds of Egyptian automata: dropping three or more books starts free spins, and the selected symbol expands to the entire drum. Simple and straightforward, it combines the mechanics of Wild and Scatter to create an "archaeological quest" for every bet.

1. Book as Wild/Scatter
The drop out of the book symbol replaces any base symbols (Wild) and at the same time serves as a bonus trigger (Scatter).
