Questions & Answers
Book of Thermopylae FAQ
Expansion requires enough appearances of the selected symbol to meet its paytable threshold. A lone appearance does not automatically qualify.
The book reveals the mystery symbol before free spins begin, and that selection remains in place throughout the bonus.
The maximum win is 50000x the bet. This is a payout ceiling, not the expected return from triggering free spins.
