About fishing slots
Fishing is one of the most crowded themes in our catalogue, and the Big Bass series alone has dozens of titles. Many of them share an idea: fish symbols carry cash values and a fisherman symbol collects them during free spins. The details, and the numbers, differ from game to game.
Because so many fishing slots look alike, the RTP version and the max win are the quickest way to tell them apart. The list below is ranked so you can compare them directly.
RTP of fishing slots
The highest headline RTPs among fishing slots are Fish Cashpot Deluxe by Skywind (97%), Fu Fish EU by Skywind (97%) and Bob Marlin Goes Deep by Yggdrasil (96.8%). The average headline RTP across all 81 is 96.06%, and the lowest is 94% on Golden Fish Tank Party.
16 of them (20%) are published in more than one RTP version, so the return depends on the version an operator runs. The widest gap is on 4 Fantastic Fish GigaBlox: from 96% down to 86%.
Volatility and max win
Volatility is published for 35 of the 81 games: 1 low, 7 medium, 19 high and 8 very high.
The largest published max wins are 27,109× on Trophy Fish, 25,539× on Bass Boss Megaways and 20,000× on Big Bass Bonanza 1000. The median max win of the 26 games that publish one is 5,000×. A max win is a rare ceiling, not a result to expect.
Studios, years and free demos
12 studios make the games in this list. The most represented are Pragmatic Play with 36 (average RTP 96.4%), Yggdrasil with 14 (average RTP 95.2%) and Skywind with 7 (average RTP 96.1%).
Release years run from 2019 to 2026; the newest are Big Bass Vegas 1000 (2026), Big Bass Raceday Repeat (2026) and Big Bass Blast (2026).
74 of the 81 (91%) have a free official demo that runs on their page with no sign-up.
