The book symbol acts as both wild and scatter, triggering free spins when three or more land anywhere. During free spins, a random expanding symbol increases your chance of landing full-screen wins. Minimum bets start at 10 XAF, while the maximum reaches 50,000 XAF. Autoplay lets you run multiple spins without manual input. Winnings are paid according to the paytable, and you can collect or continue playing after each round.
