Maximum win as a ceiling, not a target
Three or more SCATTER symbols landing anywhere on the grid start the Free Spins, but no one can tell in advance how often that happens. Every spin is random, so one session can bring many rounds or none at all. The RTP describes the return over a very large number of spins, so it does not forecast the result of the next session, whatever version runs.
Each spin on the reels pays out under one of the two RTP versions listed in the table. Which version runs here is shown only in the game rules, so read them before the first spin.
Clusters, the Tumble feature and the Random Wild Multiplier can stack on one spin, but the maximum win is a ceiling reached very rarely. A Free Spins round ends early once the cap is reached, so the figure in the table is a limit, not a target.
