Known rules, unknown rounds
On the reels, four or more SCATTER symbols anywhere on the grid start the free spins. How often that happens is not known in advance. One session can bring many free spin rounds or none, and its result is random whatever the RTP. Two sessions at the same bet can end far apart after the same number of spins.
Each spin on the reels pays out under one RTP version, and Springbok Casino decides which version it runs. That choice is shown only in the game rules, so check those rules before your first spin.
A run of wins on the reels can reach the maximum win, a ceiling that is reached very rarely. The top figure is a multiple of the bet, so the money amount rises with the stake. Treat it as a limit of the game, not as a target for any session.
