Before your first Gates of Olympus session
Choosing your bet tells you the stake, not how often the free spins come. That frequency is not known in advance, and no table on this page predicts it. The result of one session is random, whatever the RTP says about returns over a long run. Two players with the same bet can finish far apart.
Trusting a return figure starts with checking which RTP version this game runs in the lobby. That detail is shown only in the game rules, not on this page. Read the rules before you bet real money.
Plan your session around the stake, not the top prize. The maximum win is a ceiling that is reached very rarely, and it is set as a multiple of the bet. A bigger stake raises that ceiling in money, but it does not make the win more likely.
