Big Bass Bonanza Megaways slot review
Pragmatic Play’s Big Bass Bonanza Megaways expands on the popular Big Bass Bonanza slot with the Megaways system. It offers 46,656 possible ways to win, an extra top reel that can change the Megaways count, cash prizes, cascading reels, retriggers and multipliers that apply to all wins.
Fishing theme and storyline
Big Bass Bonanza Megaways brings an angling atmosphere to the online reels, with underwater scenery for players who enjoy aquatic adventures.
Visuals, audio and animations
The game looks down into a scenic river, where fish swim through clear blue water behind the reels. A 6x7 grid fills the foreground, and feature wins bring animated effects. The soundtrack reprises the familiar tune from the original Big Bass Bonanza. Sound effects, music and animations can each be switched on or off, and a full-screen option is also available.

Top Casinos to Play Big Bass Bonanza Megaways:
How Gameplay Works
This fishing-themed game has 6x7 Megaways reels, plus an extra horizontal reel above the main grid. On each spin, reels 2, 3, 5, or 5 can show 2 to 5 symbols, while reels 1 and 6 can display 2 to 6. More symbols mean more possible Megaways and potential symbol combinations.
There are no fixed paylines. Wins come from matching symbols on consecutive reels, with symbols able to land anywhere on their reel and connect to a match on the next. For instance, a 4-symbol win can have matching symbols in any positions on reels 1-2-3-4. The first symbol in a combination must land on reel 1.
Wilds can land on reels 2, 3, 4, and 5, substituting for any regular symbol. They cannot replace Scatter or Fisherman symbols.
Combinations of 2, 3, 4, 5 or 6 matching symbols pay these multipliers of the spin bet:
- Fishing Float – 2x, 5x, 10x, 25x, 50x
- Fishing Rod – 1x, 2x, 2.5x, 7.5x
- Dragon Fly – 0.25x, 1x, 1.5x, 2x
- Fishing Kit Box – 0.25x, 0.50x, 0.75x, 2x
- Schoal of Fish – 0.2x, 0.4x, 0.6x, 1.75x
- A, K, Q, J, 10 – 0.10x up to 1.75x

Free spins and other bonuses
- Free Spins: Landing 3, 4, 5 or 6 Scatters anywhere on the reels awards 10, 15, 20, or 25 free spins. In the feature, each ‘Fish Money Symbol’ is assigned a random cash value.
- Fisherman and money symbols: During free spins, the Fisherman symbol collects the value of every ‘Fish Money Symbol’, adding the amounts together for one payout.
- Fisherman re-triggers: Each landed symbol is collected. After 4 are collected, 10 more free spins are added to the remaining count. This additional 10-spin award can trigger a maximum of 3 times.
- Cascading reels: When a combination wins, its symbols vanish and new ones drop into the spaces. No extra spin-bet charge applies.
Bet Range, RTP and Variance
Big Bass Bonanza Megaways has a stated bet range of 0.20 to 100.00 per spin. Its theoretical RTP is listed as 97.7%, and it is described as a high-variance game.
Summary
Big Bass Bonanza Megaways expands on one of Pragmatic Play’s best-known video slots, Big Bass Bonanza. It was developed with Reel Kingdom, a Pragmatic Play partner. The fishing theme also features in Christmas Big Bass Bonanza and Bigger Bass Bonanza.
