Big Bass Splash 1000 takes the modifier-heavy Big Bass Splash and applies the “1000” treatment. The grid is still five reels by three rows with ten fixed paylines, and the free spins still revolve around a fisherman wild that collects fish values. The headline change is that the maximum win rises to 25,000x your stake, the highest we have seen in the Big Bass family, while the biggest single money symbol is capped at 1,000x.
It was released in December 2025. This review separates what Pragmatic Play states from what comes from third-party trackers, explains the pre-bonus modifiers, and shows what the maximum win means in pounds at UK stakes.

How to play and stakes
Choose your total stake and spin. Ten fixed lines pay left to right on adjacent reels, so you only need to pick the size of your bet. The minimum stake is normally £0.10. At UK-licensed casinos the maximum slot stake is £2 for 18 to 24 year olds and £5 for those aged 25 and over, and individual casinos can set tighter limits.
Many reviewers quote a stake range of 0.10 to 250 for unrestricted markets. That does not apply to UK players, so the UK table below is more useful:
| UK stake per spin | Max win at 25,000x |
|---|---|
| £0.10 | £2,500 |
| £1 | £25,000 |
| £2 | £50,000 |
| £5 | £125,000 |
Third-party sites also describe an Ante Bet and two bonus buys (100x and 450x for a “Super” version). Availability depends on the market and operator, and UK players should not assume they are offered.
RTP: which version?
Pragmatic Play lists 96.52% on its game page. That is the top figure, not the only one. BigWinBoard and Slots.info both report two lower settings, 95.51% and 94.53%, which are standard for Pragmatic Play, who let casinos choose. We could not confirm the lower versions on the provider’s page, so they are third-party reports. The practical step is to open the game information screen at your own casino, because UK casinos can run different RTP settings from the one in a demo or a review.
For comparison, the original Big Bass Splash lists a higher 96.71% RTP but a much lower maximum win of 5,000x.
Volatility
Pragmatic Play does not give a volatility rating on its public page. OLBG puts Big Bass Splash 1000 at very high, while other reviewers say high. Whichever label you prefer, the profile is the same: a quiet base game that leans on the free spins, and a top prize that depends on several things lining up at once. Expect big swings and plan your stake accordingly.
Max win
The maximum win is 25,000x your total stake. BigWinBoard puts the probability of reaching it at about 1 in 3.83 million spins, which is a third-party figure, not an official one. Even at that rate, treat the cap as a theoretical ceiling. More relevant to a normal session is that individual money symbols are capped at 1,000x, so a very large win needs lots of high-value fish, plenty of wilds and several multiplier steps in the same round.
Features and bonus rounds
Free spins and pre-bonus modifiers
Three, four or five scatters award 10, 15 or 20 free spins. Before the spins begin, a fishing animation can unlock up to five modifiers. According to Pragmatic Play they can add more money symbols, special symbols, extra free spins or a start at level two. Reviewers also name more fish, more fishermen and Dynamite, Hook and Bazooka style helpers that can bring in fish or wilds during the round.
Collector wilds and money symbols
During free spins, wilds that land collect all visible money symbols, with values running up to 1,000x. Pragmatic Play adds that wilds and money symbols can appear at random on the grid after each spin.
Retrigger ladder
Every fourth wild retriggers the feature with 10 more free spins. The multiplier on money collection goes to 2x on the first retrigger, 3x on the second and 10x on the third and final retrigger.
The modifiers are what separate this game from the plain original. A round that starts with extra fish and extra fishermen is a very different proposition from one with no modifiers at all.
Symbols and paytable
Pragmatic Play does not publish a paytable on its public page. One reviewer, AboutSlots, reports that five matching premium symbols pay between 50x and 200x your stake. The fish symbols double as money symbols in free spins, and the royal card symbols A, K, Q, J and 10 fill the low end. Your casino’s in-game paytable has the exact values.
Win rate and hit frequency
Pragmatic Play does not publish a hit frequency or bonus frequency for this game. The named independent tracker we use is BigWinBoard, which lists a hit frequency of 1 in 7.33 spins (about 13.6%), a free spins frequency of about 1 in 113 spins and a maximum win probability of about 1 in 3.83 million. AboutSlots quotes the same 13.64% hit rate. These sit close to the OLBG figures SlotPal’s hit rates guide lists for the original Big Bass Splash (1 in 7.3 and 1 in 113), so the family looks consistent.
Treat all of these as estimates. They describe long-run averages, not what to expect in a session.
Is Big Bass Splash 1000 enjoyable?
SlotPal’s verdict is based on the game’s mechanics, the provider’s statements and independent data, not on a long personal play session.
The modifier layer is the point of the game. It gives the moments before free spins their own small drama, because you do not know how strong the round will be until the fishing animation finishes. Once the spins start, the collector and retrigger logic is familiar from earlier Big Bass games. The downsides are the same as other very high volatility slots: long waits and the chance that a feature with weak modifiers returns very little. Reviewers note that it adds little beyond the original apart from the higher cap and the 1,000x symbol.
Verdict: a worthwhile pick for fans of the Splash format who want a bigger ceiling and can handle heavy variance. If you simply want the best return, the original Big Bass Splash lists a higher RTP, and if you prefer a gentler profile, look at lower-volatility games in the series.
