The Big Bass Bonanza series has become one of the most recognisable franchises in UK online slots. Since the original launched, developer Pragmatic Play has expanded the fishing-themed family into more than a dozen titles, each with its own volatility, RTP and bonus mechanics. For British players who enjoy free spins features and straightforward gameplay, knowing which versions offer the best value matters. This ranking weighs return-to-player percentages, maximum win potential and bonus frequency to help you decide where to cast your line.

How We Ranked the Big Bass Bonanza Games
Our ranking focuses on three measurable factors. First, RTP: most titles sit between 96.5% and 96.71% at default settings, though some can drop to around 94% depending on the operator’s configuration. Second, volatility, which ranges from medium to very high. Third, the top prize on offer, spanning from 2,000x to 10,000x your stake.
We also considered how often the free spins round triggers, since the scatter-based bonus is the heart of every Big Bass release. Games with a money-collect mechanic, such as Big Bass Bonanza, tend to deliver more frequent but smaller payouts, while multiplier-driven versions offer rarer but far bigger hits.
All figures referenced here reflect UK-licensed versions. Always check the in-game paytable, because RTP can vary between casinos even for the same slot.
The Top Big Bass Bonanza Slots in Order
| Rank | Slot | Max Win | RTP | Volatility |
|---|---|---|---|---|
| 1 | Big Bass Bonanza | 2,100x | 96.71% | Medium-High |
| 2 | Big Bass Bonanza Megaways | 10,000x | 96.70% | High |
| 3 | Big Bass Splash | 5,000x | 96.71% | High |
| 4 | Big Bass Keeping It Reel | 10,000x | 96.50% | Very High |
| 5 | Big Bass Hold & Spinner | 5,000x | 96.50% | High |
The original remains the best starting point thanks to its 96.71% RTP and 10 paylines. Megaways takes second place for its 10,000x ceiling across up to 117,649 ways to win. Splash adds a useful ante bet and a 5,000x top prize, while Keeping It Reel pushes volatility further with multiplier wilds.
Newer spin-offs such as Big Bass Mission Fishin’ and Big Bass Secrets of the Golden Lake experiment with different grids, but they tend to split opinion among UK players who prefer the classic 5×3 layout.
Which Big Bass Slot Should You Play?
If you value steady balance and frequent bonus triggers, start with the original. Players chasing headline wins should look at Megaways or Keeping It Reel, both of which offer 10,000x maximum payouts, though you will need patience and a larger bankroll to absorb the swings.
Free spins rounds in these slots typically award 10 to 20 spins, with retriggers adding more. The fisherman wild collects cash values during the bonus, and landing three or more scatters generally multiplies your total. Stake flexibility is another plus: most titles let you spin from as little as 10p.
Whichever version you choose, set a budget in pounds before you play and treat the free spins round as the main event. The fishing theme is simple, but the maths behind each release is what separates a good session from a great one.
