Sitting through a long dry spell
Three or more Scatter symbols on the reels start the bonus round, but how often that happens is not known in advance. The result of one session is random whatever the RTP. Nobody can predict the next spin from the last one. Set each session's budget before the first spin.
Nothing on the reels shows which RTP version is running. Vegastars Casino runs one of two versions of Magician's Secrets, and only the game rules say which one is live. Read those rules before your first session. The two return figures sit 0.01 points apart.
A top win on the reels pays x5,000 the bet, a ceiling reached very rarely. At the A$1 example bet that is A$5,000. Hitting it is a matter of luck, and no spin plan changes that.
