Big Bass Bonanza: fishing slot review

Pragmatic Play’s Big Bass Bonanza sets its video slot action in a lively fishing scene, with symbol combinations that can pay up to 200x the spin bet for the top symbol. The free spins round adds cash prize symbols, randomly appearing fish and wilds that can award extra spins, giving the bonus its own catch-and-collect rhythm.

Fishing theme and story

Big Bass Bonanza takes its fishing premise below the surface, where players look for matching symbols and prize fish. During free spins, catching the larger fish can bring the bonus’s prize values into play.

Visuals, sound and animation

Big Bass Bonanza presents its reels and enlarged symbols across the screen, set against a bright blue underwater scene. Players can use the settings to switch animations on or off; disabling them may conserve battery or ease lag. Separate controls also let players turn Ambient Music, Sound FX and the Intro Screen on or off, so the presentation can be adjusted to suit their preference.

How the slot plays

For players browsing an online casino for fishing-themed slots, Big Bass Bonanza offers a 5-reel layout and 10 pay lines. Its stated bet range spans low stakes through larger spins.

During the fishing round, aim to trigger the free spins feature and pursue prizes through symbol combinations, while keeping your casino bankroll in view. The bonus starts when green fish scatters appear 3, 4, or 5 times. Free spins can bring cash prizes, randomly appearing fish symbols and wilds; wilds may retrigger the feature and award extra spins. These mechanics shape the round’s potential for larger cash prizes, though outcomes depend on the symbols that land.

The spin bet multipliers listed below apply to 3, 4, or 5 symbols along a payline:

  • Fishing Float – 0.50x, 5x, 20x, 200x (pays for 2, 3, 4 or 5 symbol combos)
  • Fishing Rod – 3x, 15x, 100x
  • Dragon Fly – 2x, 10x, 50x
  • Fishing Kit Box – 2x, 10x, 50x
  • Schoal of Fish – 1x, 5x, 20x
  • A, K, Q, J, 10 – 0.5x, 2.5x, 10x

Bonus rounds and free spins

  • Free Spins: Scatter symbols landing anywhere award 20, 15, or 10 free spins for 4, 5, or 3 scatters, respectively. The feature uses special reels and has a maximum win of 2,100x your bet; reaching that amount ends the bonus.
  • Fish Money Symbols: During free spins, fish symbols display cash values. When one lands alongside a wild, the wild collects the value shown.
  • Wild Re-triggers: Wilds collected during free spins build towards additional spins: each 4th collected wild awards 10 more. The money multiplier attached to Fish Money Symbols also rises with each new batch of wild re-trigger free spins. This feature can be triggered up to 3 times.
  • Random Fish Symbols: A lone wild landing during free spins can prompt Fish Money Symbols to appear randomly on the reels.

Bet range, RTP and variance

Big Bass Bonanza lists bets from 0.10-250.00. The slot is described as high variance, with the free spins round as its main source of larger wins. Its theoretical RTP is stated as 96.71%.

Review summary

The original review places Big Bass Bonanza among Pragmatic Play’s best-known online casino games, and describes it as a popular title across iGaming. Its high-variance design centres on a substantial free spins feature, supported by paying symbols in the base game. Those mechanics can produce prizes, but they do not ensure a profitable session.
