Big Bass Bonanza launched in December 2020 from Reel Kingdom (Pragmatic Play's in-house studio specializing in fishing themes) and kicked off an entire franchise that now counts a dozen variants (Splash, Hold & Spinner, Christmas, and more). It's the original slot in the series — clean mechanics, no bonus buy, and a 96.71% RTP in its high version. Fisherman Wilds collect Cash Fish symbols during free spins with a progressive multiplier (x1→x2→x3→x10) that can turn a trigger into a big win.
This is a full Big Bass Bonanza review: breaking down the Fisherman Wild mechanic, the official RTP and its degraded versions, a comparison against its sequels (Splash, Hold & Spinner), and where to play in 2026.
TL;DR — Big Bass Bonanza in 4 points
- Reel Kingdom slot (on the Pragmatic Play platform), Dec 2020, a 5x3 grid over 10 paylines. RTP 96.71% in the high version (a 95.67% degraded version is often the default at casinos).
- Medium-high volatility (4/5), max win 2,100x the stake. Free spins hit frequency: 1 trigger every 113 spins on average.
- NO bonus buy available — it's the original, without the feature, which makes base-game grinding mandatory.
- Massive availability: 95%+ of Pragmatic-carrying casinos. Top 5 spots: SpinAura, BetRiviera, Millioner, BetMac.
Why Big Bass Bonanza is the most-played fishing slot
Released in late 2020, Big Bass Bonanza exploded in popularity thanks to three factors:
- Simple, legible mechanic: you instantly see the Fisherman reel in the Cash Fish — no complicated rules
- A visible progressive multiplier: the multiplier counter climbs visibly (x1 → x2 → x3 → x10) as you collect wilds
- A universal theme: fishing is calm and approachable, not anxiety-inducing like Hacksaw's RIP City or NoLimit's output
- Massive availability: Pragmatic rolled it out to nearly every casino
- A "pure" original version: no bonus buy = a more authentic experience for purists
It's also the slot that launched an entire commercial franchise — every later variant (Splash, Hold & Spinner, Christmas) builds on this base.
The mechanics in detail
Base game (5x3 over 10 paylines)
A classic grid: 5 reels x 3 rows, 10 fixed paylines. Symbols: a buoy, a tackle box, a hook, a fly (low value) plus A/K/Q/J/10 card royals (very low value). The Fisherman Wild appears in the base game and substitutes for every symbol except the Scatter (the Scatter symbol is another fisherman).
Triggering Free Spins
At least 3 scatters on reels 1, 3, and 5:
- 3 scatters = 10 free spins
- 4 scatters = 15 free spins
- 5 scatters = 20 free spins
Official hit frequency (per SlotCatalog): 1 trigger every 113 spins on average. That's a decent hit rate for a Pragmatic slot with this kind of mechanic.
Cash Fish symbols
During free spins, Cash Fish symbols appear with random values:
- Small fish: x2 to x10 stake
- Medium fish: x10 to x100 stake
- Large fish: x100 to x500 stake
- Mega fish: x500 to x2,000 stake (rare)
Cash Fish are automatically collected every time a Fisherman Wild appears on screen.
Multiplier progression (the heart of the game)
During free spins, the multiplier progresses based on the number of wilds collected since the bonus began:
| Wilds collected | Multiplier |
|---|---|
| 0-3 | x1 |
| 4-7 | x2 |
| 8-11 | x3 |
| 12+ | x10 |
The multiplier applies to every Cash Fish collected by subsequent wilds. The earlier you collect in the bonus, the more explosive the big-win potential.
Retrigger
4 wilds collected during the bonus = +10 extra free spins. This lets you extend the bonus and accumulate more Cash Fish.
RTP — 96.71% (but often 95.67% at casinos)
Pragmatic offers several RTP versions of Big Bass Bonanza, and the default version at many casinos is 95.67% (not the 96.71% high one):
| Version | RTP | Recommendation |
|---|---|---|
| High | 96.71% 🏆 | Play this if it's available |
| Standard | 95.67% ⚠️ | Often the default — acceptable but not optimal |
| (No version as degraded as The Dog House) |
Verification: open the slot in-game → the "i" button in the bottom left → look for "RTP". If you see 95.67%, that's the standard version. If it's 96.71%, that's the high one — hold onto that casino.

Strategies by budget
Small budget (< €100)
Stake €0.10-€0.20. You can run 500-1,000 spins with €100. Without a bonus buy, grinding is mandatory. Statistically, the 96.71% RTP returns roughly €96.71 for every €100 wagered. Natural FS triggers happen roughly every 113 spins on average — patience is required but realistic.
Medium budget (€300-€700)
Stake €0.40-€0.80. You can trigger 5-10 free spins sessions on this budget. Strategy: grind the base game, chase natural triggers, and hope for the x10 multiplier when the bonus lands.
Large budget (€1,000+)
Stake €1-€2. Beyond that you're taking on too much variance for a slot with only a 2,100x max win. If you want bigger upside, play Big Bass Hold & Spinner instead (max 10,000x, with a bonus buy available).
