Before the reels stop, the result stays open
Scatter symbols land on the reels at random, and the bonus round starts only when enough of them show. How often that happens cannot be known before a spin. The number of bonus rounds in one session is random. The result of one session is also random, whatever the RTP says.
Each spin pays out on the reels of whichever RTP version the lobby runs. Which version that is appears only in the game rules, not on the reels. Read those rules before you start, because a session cannot show which version it runs on. The RTP figures in the table describe the long run only, not one session.
A winning combination on the reels pays a multiple of the bet, and the top of that scale is the maximum win. The maximum win is a ceiling, and it is reached very rarely. Treat it as a limit on the payout, not as a promise for any session, and check the money figure for the bet you choose.
