Quick answer: the best fishing slots are Pragmatic Play’s Big Bass Bonanza and Big Bass Splash (both 96.71% RTP, with 2,100x and 5,000x max wins) and Blueprint Gaming’s Fishin’ Frenzy (96.12%). In most of them, a fisherman wild collects the cash values on fish symbols during free spins.

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.

The best fishing slots online

1. Big Bass Bonanza (Pragmatic Play, 2020)

RTP96.71% (lower versions exist)
VolatilityMedium-high
Layout5×3, 10 paylines
Max win2,100x

The game that made fishing slots a genre. In free spins, the fisherman wild collects the cash values on fish symbols, and every fourth fisherman collected adds more spins and raises the multiplier. Read our full Big Bass Bonanza review.

2. Big Bass Splash (Pragmatic Play)

RTP96.71%
VolatilityHigh
Layout5×3, 10 paylines
Max win5,000x

The higher-volatility sequel keeps the fisherman-collect free spins but adds random modifiers before the bonus, and more than doubles the max win. Choose it if you want a bigger top prize and can handle longer dry spells. Read our Big Bass Splash review. Two later 5×3 games raise the cap to 10,000x: Big Bass Hold & Spinner adds a base-game money respin, and Big Bass Amazon Xtreme collects fish in the base game with a multiplier of up to 50x. Big Bass Keeping It Reel also reaches 10,000x, with a fish pot and Golden Wilds, while Big Bass Mission Fishin’ lets you choose between free spins and a Stack the Cash respin. On Megaways reels, Big Bass Hold & Spinner Megaways goes up to 20,000x, and Floating Dragon uses the same free spins with a coin respin added. Three 2024 spin-offs change the formula in other ways: Big Bass Floats My Boat adds multipliers that grow as money symbols land in free spins, Big Bass Secrets of the Golden Lake hides a Golden Lake mode behind a card pick, and Big Bass Day at the Races swaps fish for racehorses and reaches 10,000x. Big Bass Bonanza Reel Action is the original game with a 100x bonus buy added.

3. Big Bass Bonanza Megaways (Pragmatic Play)

RTP96.7%
Layout6 reels, up to 46,656 ways, tumbling wins
Max win4,000x

RTP96.12%
VolatilityLow-medium to high (sources differ)
Layout5×3, 10 paylines
Max win5,000x in most sources

The UK classic that predates Big Bass. Three or more boat scatters trigger up to 20 free spins, where fish symbols carry cash values that the fisherman wild collects. The series now includes several sequels and Megaways versions with different RTPs, so check which one you are playing.

5. Big Bass Halloween (Pragmatic Play, 2023)

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.
