Starlight Princess 1000 outcomes stay unpredictable
Four or more SCATTER symbols anywhere on the 6x5 grid start the Free Spins, but how often that happens is not known in advance. Each spin is random. The RTP describes the return over very many spins, so the result of one session can be far above or far below it, whatever RTP version runs.
Winning symbols tumble away after each win and new ones drop into the 6x5 grid. Which of the two RTP versions runs on this game is shown only in the game rules, so read them before the first spin.
Multiplier orbs can hit during a winning tumble sequence and multiply the whole sequence win, so a single run of wins can grow fast. The maximum win is a ceiling reached very rarely, and no one can count on it.
