BetsRank Verdict

Hands-on testing by Alexandre Dubois — bonus tested, multiple sessions

The cult fishing slot from Reel Kingdom (Pragmatic Play's in-house studio) that launched the entire Big Bass franchise. Released in late 2020, its mechanic is simple but addictive: 3 scatters trigger 10 free spins (4 scatters = 15 spins, 5 scatters = 20 spins), during which the Fisherman wild collects Cash Fish symbols and applies a progressive multiplier (x1 → x2 → x3 → x10 depending on how many wilds have been collected). There's no bonus buy available — this is the original, without that later addition, which makes grinding the base game mandatory (one natural trigger roughly every 113 spins on average). The max win is a modest 2,100x, but the hit frequency is solid.

Strengths

+Simple, addictive mechanic (Fisherman wild plus Cash Fish)
+Solid free spins hit frequency at roughly 1 in 113 spins
+96.71% RTP in the high-RTP version (verify in-game)
+Extremely widely available across casinos that carry Pragmatic Play

To consider

−Modest 2,100x max win (versus 5,000x on Big Bass Splash or 10,000x on Hold & Spinner)
−NO bonus buy available (it's the original title)
−Degraded RTP versions are common (95.67% is often the default)
−Basic mechanics compared to its more modern sequels

About Big Bass Bonanza

Released in December 2020 by Reel Kingdom (Pragmatic Play's in-house studio specializing in fishing-themed slots), Big Bass Bonanza launched what is now an entire Big Bass franchise spanning roughly a dozen variants. It runs on a classic 5x3 grid with 10 paylines, with an RTP of 96.71% in the high-RTP version. The bonus round triggers with 3 Fisherman scatters and awards 10 free spins (4 scatters = 15 spins, 5 scatters = 20 spins). During the free spins, the Fisherman wild appears and automatically collects every visible Cash Fish symbol (worth x2 to x2,000 the stake). The more consecutive wilds you collect, the higher the multiplier climbs: x1 → x2 (after 4 wilds collected) → x3 (after 8 wilds) → x10 (after 12 wilds). Worth noting: there's no bonus buy on the original — it's the 'purest' entry in the whole series.

❓Big Bass Bonanza FAQ

What is the RTP of Big Bass Bonanza?▾

The official RTP is 96.

71% (high version). But be careful — the default version deployed by many casinos is 95. 67% (one full point lower). Pragmatic ships multiple RTP versions and casinos can choose which one to deploy. Always check the in-game 'i' button to confirm.

Why is there no bonus buy on Big Bass Bonanza?▾

It's the original of the series, released in late 2020 before bonus buys became standard across the industry.

All the sequels (Splash, Hold & Spinner, Christmas, and more) include a bonus buy at 100x the stake. If you want to skip the base-game grind, play a sequel instead.

Big Bass Bonanza vs. Big Bass Splash — which one should you pick?▾

Big Bass Bonanza is the original: no bonus buy, a 2,100x max win, and a stripped-down mechanic.

Big Bass Splash (2022) offers a 5,000x max win, a bonus buy at 100x the stake, and multipliers climbing up to x10. To discover the franchise, start with Bonanza. To chase a bigger hit, go with Splash.

How often do the free spins trigger?▾

On average, one natural trigger every 113 spins (per public slot data).

That's decent for a Pragmatic title but still requires patience. Without a bonus buy, grinding is mandatory.

Is Big Bass Bonanza widely available?▾

Yes — it's carried by the vast majority of casinos that offer Pragmatic Play, making it one of the most widely distributed slots on the market.
