From the base game to the free spins
Deciding how long to stay in Gates of Olympus 1000 means accepting that the free spins arrive at random. Nobody can know in advance how often the bonus round comes, and no table on this page changes that. The result of one session is random whatever the RTP, so a good stretch or a dry one tells you nothing about the next.
Checking which RTP version is running is possible only in the game rules. Gates of Olympus 1000 has two versions, and each one is shown in the table below. Read those rules before your first spin, because the version you play sets the long-run return on the same bet.
Setting a bet means setting the ceiling, too. The maximum win is 15,000 times the bet, which comes to A$15,000 at the top example bet of A$1. A ceiling reached very rarely is a limit on the top, not a forecast of the average result.
