Sent in by viewers in our Discord and read straight from the game provider's replay of the round — the bet, the win and the game name all come from the provider, not from us. Player names are shortened. Multipliers are the win divided by the base bet. These are wins people chose to share, so they are not a sample of how Opa Santorini! pays on average: for that, see the recorded hunt data above.
We have opened Opa Santorini! 5 times across 5 separate bonus hunts between 20 Jul 2026 and 26 Aug 2026 and recorded every result. Across those 5 opens the median result was 48.6× the bet, against 50.1× for every slot in our recorded dataset. The biggest single result we have recorded on it is 118.9×. 1 of those 5 opens was 100× or better. 5 opens is a small sample and describes only these recorded sessions — it is not this slot's RTP and it does not predict what your next bonus will do.
