Big Bass Bonanza
The starting point of one of the largest families in the industry. A classic five-reel structure carrying one strong idea: the fisherman collects the money on screen.

How Big Bass Bonanza works
- Ten fixed paylines, no tumbles and no clusters.
- The fisherman wild collects every money symbol visible on the reels.
- Every four fishermen collected retriggers spins and raises the multiplier.
- Stepped multiplier of 2x, 3x and 10x in the extended round.
The total bet is what matters, not any per-line figure. The studio tunes symbol weights and paytable values to hit the published return over the long run.

This is not a recommendation
We publish technical data, not playing advice. RTP values come from the developer's documentation; an operator may deploy a different configuration, so check the figure inside the game's own info panel. Gambling can be addictive — only ever stake money you can afford to lose.
Who actually built Big Bass Bonanza
Almost every listing names Pragmatic Play as the developer. That is the distribution relationship, not the studio. Big Bass Bonanza was built by Reel Kingdom, a small Welsh studio, and released in December 2020 through Pragmatic Play, which announced the game as a partnership at the time. Reel Kingdom had already shipped several titles that went nowhere before this one; the Big Bass series that followed it now runs to dozens of games.
The distinction matters when you compare sheets. Pragmatic Play games and Reel Kingdom games are certified and configured through the same platform, so an operator that offers one usually offers the other, but the maths, the volatility profile and the RTP configurations belong to the studio that built the title, not to the brand on the lobby tile.
Where the 96.71% comes from
Pragmatic Play publishes 96.71% on its own game page for Big Bass Bonanza, under Basic Game Info. That is the primary source for the figure on this sheet, and it is the number to compare an operator's panel against.
Two numbers around this game are routinely mixed up. The 2,100x on this sheet is the maximum win for a single round. Pragmatic Play's own description mentions money symbols worth up to 2,000x during the bonus, which is the ceiling on one collected symbol, not on the round. Neither figure says anything about how often either is reached.
The reduced configurations: what can and cannot be confirmed
Pragmatic Play lets operators integrate several certified maths versions of the same title, and the studio does not publish the full list for Big Bass Bonanza. What circulates instead is second-hand. Different pages state the alternative settings as 95.67%, 94.62%, 94.5%, and in one case a version as low as 88%. None of those numbers appear on Pragmatic Play's own page for this game, and the pages that carry them are affiliate sites rather than the developer or a regulator.
Part of the confusion is traceable. The pair 95.67% / 94.62% is documented repeatedly for Bigger Bass Bonanza, the 2021 sequel, and appears to have been copied across to the original game. The two titles have different reel sets, different paylines and different maximum wins, so there is no reason to assume they share a configuration ladder.
So the honest position is this: 96.71% is the published top configuration and is confirmed by the developer. Lower configurations exist as a mechanism — Pragmatic Play's platform supports them and operators use them — but the specific values quoted around this title are unverified, and we do not republish them as fact. The figure inside the game you are about to play is the only one that applies to you.
Reading the RTP in the game itself
The check takes under a minute and works the same way in demo and real-money mode, because an operator's demo runs the configuration that operator integrated.
- Open the game and find the menu: usually ⓘ, ≡ or a gear icon in the corner of the frame.
- Go to game rules, help or paytable. The return figure is normally on the last page.
- Read the number rather than the range. Some panels print a range across a family of versions; the active value is the one stated for that installation.
- If the panel states no RTP at all, that is itself information about the operator, not about the game.
- Check again after switching sites. The same title under the same name can run a different maths version one domain over.
Which Big Bass game is actually in front of you
Search results for this title mix in at least six different games. The figures below come from Pragmatic Play's own game pages, and they describe the top configuration in each case.
| Title | Released | Grid and lines | Headline figure |
|---|---|---|---|
| Big Bass Bonanza (this sheet) | December 2020 | 5x3, 10 lines | RTP 96.71%, round cap 2,100x |
| Bigger Bass Bonanza | September 2021 | 5x4, 12 lines | Money symbols up to 4,000x |
| Big Bass Bonanza Megaways | 2021 | Variable ways | Money symbols up to 4,000x; 3–6 scatters award 10–25 spins |
| Christmas Big Bass Bonanza | November 2021 | 5x3, 10 lines | Seasonal reskin of the original feature set |
| Big Bass Bonanza – Reel Action | 2024 | 5x3 | RTP 96.50%, round cap 2,100x |
| Big Bass Bonanza 3 Reeler | December 2024 | 3x3, 5 lines | Win potential 5,000x |
| Big Bass Bonanza 1000 | 2025 | 5x3, 10 lines | Win potential 20,000x |
Reel Action is the clearest example of why the title has to be read exactly: it is the same fishing frame and the same 2,100x cap, but the published return is 96.50%, not 96.71%. A search for "big bass bonanza rtp" returns both numbers, and both are correct for different games.
Questions people actually ask about this game
Is 96.71% the RTP I will be playing? Only if your operator integrated the top configuration. The published figure is the developer's; the deployed figure is the operator's, and the panel is where the two are reconciled.
Does the free spins round have its own RTP? No. The return is a property of the whole maths model. On a game where most of the value sits in the feature, the base game will feel worse than the headline suggests, which is a volatility effect rather than a different RTP.
Why do some sites list high volatility and others medium-high? Volatility labels are not standardised. Pragmatic Play publishes a rating for its own titles, and third parties re-score it on their own scales. Treat the word as a shape, not a measurement.
Is the 2,100x realistic to plan around? It is a cap, and the probability of reaching it is not published. A maximum win figure sets the ceiling on the arithmetic and nothing else.
