A theme is art direction, not maths
Two fish games can share every symbol and still be priced differently. Across this theme the published RTP runs 90.02% to 98.60% — a 8.58 point spread inside one visual category. Pick on the number, not the artwork.
We compared 25 of these games across two or more casinos: 8 are served at different RTP builds depending on the operator, averaging 0.25pp of difference. Where you play a fish slot can matter as much as which one you pick.
