The plate at the top of this page lists return to player at 96.08%, maximum win at 800x, a grid of five reels and three rows, ten paylines, a hit frequency of 23.0%, provider NetEnt, released in 2012. Those are the figures the provider publishes. The return is a long-run average across every stake and every player; it is not a target for a session, and a short run of spins can land far either side of it.
A 96.08% return means that, across an enormous number of spins, the game is designed to return about A$96.08 of every A$100 staked. It does not mean a player gets that back in an evening. The 23.0% hit frequency says roughly one spin in four produces some return, which is frequent, but many of those returns will be smaller than the stake that produced them.
