Mid-session, when Free Spins feel overdue
Set your stake knowing that nobody can predict how often the bonus round arrives. Each spin is random, so one session can finish well above or well below its expected return. Treat the RTP as an average over a very large number of rounds, not as a promise for your next session. Free Spins may come early, late, or not at all in a given session.
Open the game rules before you stake, because the RTP version in use is shown only there. Do not assume a version from another game with the same name, since versions of one slot can pay back differently.
Read the top prize of Lady Wolf Moon as a ceiling, not as an expected result. The maximum win is a multiple of the stake, so a larger bet raises the cash ceiling in step. That ceiling is reached very rarely, and no one can say in advance whether your session will be one of them.
