Gates of Olympus Super Scatter cannot promise a payout
Scatter symbols land on the reels at random, and the free spins start only when enough of them appear on one spin. How often that happens is not known in advance. Two sessions with the same bet can look very different, because the result of one session is random whatever the RTP says.
Nothing on the reels tells you which RTP version is running. That detail sits only in the game rules, so read them before the first spin. The versions differ only slightly, and the difference shows over a very long run, not in one session.
Big wins come from tumbles, and multiplier orbs can stack on top of them. The maximum win is a ceiling, not a target, and it is reached very rarely. Nobody can plan for that top result, and no session can be relied on to reach it.
