What can nobody promise before the first spin?
Decide your budget before the first spin, because how often the Free Spins round comes cannot be known in advance. Each spin is random, so the result of one session stays open whatever the RTP of 96.50 says. That figure describes the return over a very large number of rounds, not what one evening will pay.
Open the game rules before you bet, because they are the only place that shows which RTP version this lobby runs. Do not rely on a title or on an RTP you saw in another game. Read the version line and match it to the RTP table on this page.
Treat the maximum win as a ceiling, not a target. It stands at x5,000 of the bet, which is A$50,000 at the A$10 example top bet and A$1,500,000 at the A$300 max bet. Nobody can tell when that ceiling will be reached, or whether it will be reached at all.
