Bonus round timing and the win ceiling
Every spin of Retro Sweets lands new symbols on the 6x9 grid at random. How often the bonus round comes is not known in advance, and the result of one session is random whatever the RTP. A high RTP describes the average over a very large number of rounds, not the outcome of your next hour.
The reels stop on new symbols after each spin, while the RTP version behind them is shown only in the game rules. Two players on the same version can still see very different sessions, because each spin is decided on its own. The version in use sets the long-run return, not the result of a single spin.
A round on the reels can reach the top prize, but the maximum win is a ceiling reached very rarely. No session can be planned around it. The figure marks the edge of the paytable, not the expected result. Read it alongside the RTP and high volatility before setting a bet.
