Bonus arrivals nobody can forecast
Scatter symbols land at random, so the free spins start at a point nobody can know in advance. How often they come is not known before you play, and no run of spins shows when the next one starts. The result of one session is random whatever the RTP, because the RTP is a long-run average, not a promise for any single session.
Each spin on the reels pays under one of two RTP versions. Only the game rules show which version runs here, so check that section carefully before you rely on any percentage shown elsewhere on this page.
Wins on the reels stop at a fixed ceiling, set as a multiple of the bet, and the top of that ceiling is reached very rarely. The maximum win caps what one bet can pay, not a target the reels aim for. Reaching it is possible but rare, so treat the ceiling as a limit, not an expectation.
