Fishing slots are one of the most popular themes online, thanks mainly to Pragmatic Play’s Big Bass series and Blueprint’s Fishin’ Frenzy. Most follow the same simple idea: fish symbols carry cash values, and in free spins a fisherman wild reels them in. Here are five of the best fishing slots, with fact-checked RTPs, volatility and max wins.

How fishing slots work
- Fish money symbols: fish land with cash values attached, usually multiples of your bet.
- Fisherman wild: in free spins, each fisherman collects the value of every fish on screen.
- Progression: in many games, collecting fishermen adds extra spins and raises a multiplier.
- Most value is in the bonus: base-game wins are usually small, so these games can feel quiet until free spins land.
How to choose a fishing slot
- For steadier play: Big Bass Bonanza (medium-high volatility).
- For a bigger top prize: Big Bass Splash (5,000x) or Fishin’ Frenzy.
- For more ways to win: Big Bass Bonanza Megaways.
- Check the RTP version: Pragmatic Play games often come in lower RTP versions at some casinos.
