From guessing wins to reading the ceiling
Free Spins begin when Scatter symbols land on the reels, and no player can know in advance when that will happen. A session may end with no bonus round, or it may hold more than one. The RTP describes the return over a long run of play. It does not predict one session, so the result of any single visit stays random whatever the RTP.
Every spin settles under one RTP version. Which version is in use here appears only in the game rules. Players who want that detail should open the game rules before the first spin, and compare the version named there with the RTP table on this page.
Combinations on the reels can reach the top ceiling of the game, but that ceiling is reached very rarely. The maximum win is a multiple of the bet, so the money amount grows with the stake. Hitting it is not an expectation for any session, and no session is built around reaching it.
