Big Bass Bonanza Megaways is the Megaways rebuild of Reel Kingdom’s fishing series, published by Pragmatic Play in November 2021. Its top RTP tier is 96.70%, the maximum win is 4,000x the stake, and the grid stretches to 46,656 ways to win.
The combination is unusual for the range: the highest headline RTP of any Big Bass title sits next to one of the smallest win ceilings. Volatility is rated high, 5 out of 5, and stakes run from 0.20 to 100 — a lower maximum bet than the rest of the series allows.

How Big Bass Bonanza Megaways works
The game is played on six reels that change height from spin to spin, plus a horizontal four-symbol reel running across the top of the main grid. That variable geometry is what Megaways means: the number of active ways is recalculated on every spin and peaks at 46,656. Wins form left to right from the first reel across adjacent reels, and row position is irrelevant.
Every win triggers a tumble. The symbols that formed the combination are removed, whatever remains drops down to fill the gaps, and fresh symbols fall in from above. If the new arrangement makes another win, it pays and tumbles again; the sequence ends only when a drop produces nothing. One paid spin can therefore resolve into several consecutive wins before the next stake is taken.
Visually this is the series unchanged — shimmying fish over the deep-blue underwater backdrop, with the same island soundtrack as the original Big Bass Bonanza. The fish scatter is the symbol that matters in the base game: it does not pay on ways, it counts toward the free spins trigger. One widely-read review describes five main reels, but six is the count the game’s spec listings give and the only one consistent with 46,656 ways, which is six to the sixth power.
Big Bass Bonanza Megaways bonus features
Three, four or five scatters award 10, 15 or 20 free spins. The round rewrites the tumble rules: fish money symbols, which carry printed cash values, are no longer cleared away when a win resolves. They drop to the bottom of the screen and stay there, building a row of values waiting to be claimed.
The claim comes from the fisherman symbol. When one lands while money symbols are on screen, it collects every value showing and pays the total. Fishermen are also banked in a side meter, and every fourth one retriggers the round with +10 free spins while stepping the collection multiplier up — x2 first, then x3, then a final x10. After that third step there are no further retriggers, so the round has a hard structural end.
Two random helpers exist to force the halves of that mechanic together. Dynamite fires when one or two fishermen are on screen with no fish, adding extra fish symbols in random positions. Bazooka does the opposite job, exploding every symbol in view except the fishermen to clear space for a new drop. Neither is player-controlled and neither produces a collect on its own — they only raise the chance that a fisherman and a screen of values coincide.
Big Bass Bonanza Megaways RTP, volatility and max win
The game ships in three RTP configurations: 96.70%, 95.66% and 94.62%. The operator, not the player, chooses which one is loaded, and more than two percentage points of long-run return separate the top setting from the bottom. Worth knowing: SlotCatalog lists 95.66% as this game’s headline figure, which suggests the middle tier is deployed often enough to be mistaken for the default. Open the in-game information screen before you spin and read the RTP stated there — it is the only figure that describes the version you are actually playing.
Volatility is rated high at 5 out of 5. Pragmatic Play does not publish a hit frequency for this title, so how often the base game pays is not something we can quote. What is clear from the structure is that tumbles do their work in small increments while the free spins carry the weight, and the 4,000x ceiling limits how much a single exceptional round can return. Expect a long, uneven session in which the bonus is the only meaningful swing.

- Up to 46,656 ways to win, with tumbles on every winning spin
- Free spins collect mechanic is carried over intact from the original
- Dynamite and Bazooka modifiers work to put fishermen and fish on screen together

- No bonus buy is listed, so free spins must be landed the slow way
Big Bass Bonanza Megaways compared with other Bonanza slots
Within the series the Megaways build trades ceiling for spread. Big Bass Bonanza 1000 keeps the plain 5×3 grid and 10 paylines but caps at 20,000x against 4,000x here, on a slightly lower 96.51% top RTP. Reel Action is lower again at 2,100x, though its 1-in-4.83 base-game hit rate is the friendliest in the family. Big Bass Football Bonanza reaches 5,000x on 96.50%. If Megaways specifically is the draw, Big Time Gaming’s Bonanza Falls runs up to 117,649 ways at 96.51% with a 93,540x maximum.
Verdict
This suits players who like Megaways geometry and tumbling wins, and who want the highest published RTP tier in the Big Bass range in exchange for a 4,000x ceiling. It is a poor fit for anyone shopping on the headline number — Big Bass Bonanza 1000 caps five times higher and Keeping it Reel two and a half times higher. The 100 maximum stake also rules it out for high-stakes play. Read it as the most playable version of the series rather than the most explosive one.
