Where the figures stop and luck starts
Each spin deals a fresh 8x8 grid, and whether four or more SCATTER symbols land is decided by chance on that spin. How often the bonus round arrives is not known in advance. The RTP describes the return over a very long run, not the result of one session, which stays random whatever the RTP is.
The reels pay out under one RTP version of the game. Which version Palmerbet runs is shown only in the game rules, so open them before you start. The figures table lists both versions with their return per A$100 staked.
The top prize on the reels is set at 50,000 times the bet, a ceiling that is reached very rarely. The figure is the most a single bet can return, and how close a session comes to it depends on chance, so it is not a target for any player.
