Why 96.50 does not predict one session
96.50 is the long-run average return of this version, and it says nothing about one visit. How often the bonus round comes is not known in advance. A bonus can land early in a session or not at all. The result of one session is random, whatever the RTP is. Nobody can predict it from the figures alone.
96.50, 96.51 and 96.52 are the RTP figures of the versions in this series. Which version runs here is shown only in the game rules, so read that panel before you play. The figure sets the long-run return, so it matters.
x5,000 is the ceiling of this slot, which is A$1,500,000 at the A$300 maximum bet. Such a win is reached very rarely, and nothing in the figures tells you when it might come. Treat it as a limit on the game, not a target for any session.
