Expect Free Spins at random, not on schedule
4+ scatter symbols anywhere on the 6x5 grid start Free Spins, but no figure tells a player how often that happens in advance. Free Spins depend on random results on every spin, so one session can bring them early, late or not at all, and the RTP version does not change that.
Four RTP versions of Sweet Bonanza 1000 exist, and the one a game runs is shown only in the game rules. Check the game rules before the first spin, because the version changes the long-run return on each bet, not the result of any single spin.
25,000 times the bet is the ceiling of Sweet Bonanza 1000, a limit that is reached very rarely. On a A$10 bet that ceiling reads A$250,000, but few sessions come near it, and no player can plan around it.
