Slot Details
The Big Bass Bonanza 1000 slot is played on 5 reels and 3 rows with 10 fixed paylines. You need 3 or more matching symbols from left to right, on adjacent reels and starting from the leftmost reel, across any of the 10 paylines to form a winning combination. The only exception is the fishing float symbol where 2 or more are required.
In terms of bet options, you can play from as little as 10p per spin. With the maximum bet ranging up to £250 a spin, use the plus and minus buttons to change your bet. Non-UK players can speed up the spin speed with Turbo/Quick Spin mode or play up to 1,000 auto spins with the Autoplay function.
The Big Bass Bonanza 1000 RTP rate is 96.51% which is significant higher than the online slot average of around 96%. However, Pragmatic Play has created 95.51% and 94.51% RTP versions which may be used at your chosen slots site (a quick glance at the Paytable will determine which rate you’re playing with). The Big Bass Bonanza 1000 free demo above uses the highest RTP rate: this is also the case for the majority of free demo slot games at OLBG.
Classed at very high volatility (5/5), the hit frequency rate is 13.19%. This means a winning combination will land, on average, every 7.58 spins. Triggering the all-important Free Spins feature will happen every 1 in 116 spins.
The Big Bass Bonanza 1000 slot game offers 20,000 times bet max wins ensuring it offers the highest win potential of any Big Bass slot. The chances of winning the max win (known as the max win probability) are 1 in 6,366,645 spins whilst winning 1,000 times your total bet or higher will occur every 9,237 spins.

Big Bass Bonanza 1000 Expert Review
Theme, Audio + Symbols
With a fishing theme, the Big Bass Bonanza 1000 slot is the 25th game in the Big Bass slots series. This time around, Pragmatic Play’s favourite fisherman returns for a supercharged adventure as the they’ve incorporated the 1000 series for huge max win potential.
Set underwater, the visuals are similar to other Big Bass games but there is a green tinge rather than a blue one (like in Big Bass Amazon Xtreme). With an upbeat and jolly soundtrack, it uses the same symbols as its predecessors.
Low-value symbols include colourful A, K, Q, J and 10 royals. The higher-value symbols are represented by money fish, tackle boxes, fishing rods, dragonflies and fishing floats. Best paying is the fishing float symbol which awards 200 times your total bet for 5 in combination.
Big Bass Bonanza 1000 also comes with a Fisherman Wild symbol which substitutes for all paying symbols but only appears during the Free Spins feature. To trigger the free spins, you need to Big Bass Scatter symbol which can appear on all 5 reels. Below, there is a list of all symbol payouts and functions:
- Q/J/10: 3, 4 or 5 = 0.2, 1 or 5 x bet
- A/K: 3, 4 or 5 = 0.2, 2.5 or 10 x bet
- Fish Money: 3, 4 or 5 = 1, 5 or 20 x bet
- Tackle Box/Fishing Rod: 3, 4 or 5 = 2, 10 or 50 x bet
- Dragonfly: 3, 4 or 5 = 3, 15 or 100 x bet
- Fishing Float: 2, 3, 4 or 5 = 0.5, 5, 20 or 200 x bet
- Fisherman Wild: Substitutes for all symbols above & collects Fish Money symbols during free spins

Big Bass Bonanza 1000 Mobile
Big Bass Bonanza 1000 has been created using HTML5 technology. Adapting to any device you use, you can play this game on laptops, PCs, mobiles and tablets: this includes iOS and Android smartphones with Portrait Mode used to occupy more of your handheld screen. This is the case for all Pragmatic slots.
Bonus Features
The Big Bass Bonanza 1000 slot comes with 5 bonus features. All about the Free Spins feature, Fisherman Wilds collect fish money symbols which can reach 1,000 x bet. Every 4th Fisherman Wild retriggers the feature for extra free spins and a fish money multiplier up to 10x. You can expect some random extras to help you win more too.
Free Spins
When you land 3 or more Big Bass Scatter symbols anywhere during a base game spin, you’ll trigger the Free Spins feature. 3, 4 or 5 scatters will result in 10, 15 or 20 free spins, respectively. If you land 2 scatters, a 3rd scatter can be randomly reel in to trigger the feature.
In the feature, the Fisherman Wild symbol comes into play. Appearing on all 5 reels and substituting for all paying symbols, Fisherman Wilds collect all fish money symbols on the reels. Fish money symbols will contain random bet multiplier values ranging from 2 to 1,000 times your total bet.
Every 4th Fisherman Wild landing during the free spins will retrigger the feature. This will reward you with 10 extra free spins and the multiplier increasing to 2x, 3x and finally 10x:
Level | Fisherman Wilds Collected | Extra Free Spins | Fish Money Multiplier |
---|---|---|---|
1 | NA | 10-20 | 1x |
2 | 4 | 10 | 2x |
3 | 8 in total | 10 | 3x |
4 | 12 in total | 10 | 10x |
The Free Spins feature also benefits from random extras. Randomly, when there is at least 1 Fisherman Wild on the reels, fish money symbols can appear in random positions which are then collected. There is also a Bazooka feature where fish money symbols are randomly added to the reels when Fisherman Wilds appear. Lastly, there is a Hook feature where both Fisherman Wilds and fish money symbols can be brought onto the reels.
Ante Bet
There is an optional Ante Bet feature which costs 1.5 times your total bet (i.e. a £1 spin will be £1.50 per spin). If you exercise this feature, you increase the chances of triggering the Free Spins feature as more Big Bass Scatter symbols appear on the reels. The RTP rate remains the same though.
Buy Free Spins
Non-UK players have 2 bonus buy options. With the RTP rate remaining at 96.51%, 95.51% or 94.51%, below is the price for each option:
- Free Spins feature: 100 x your total bet (3 Big Bass Scatters)
- Super Free Spins feature: 450 x your total bet (Higher chance of 1,000 x bet fish money symbols)
Expert Verdict

Big Bass Bonanza 1000 is the 25th slot in the series and offers the same gameplay as its predecessors but with much bigger max win potential: up to 20,000 x bet.
The Big Bass Bonanza 1000 slot may be the 25th game in the illustrious fishing series but the gameplay has remained the same throughout. The visuals are virtually identical to other games so you’ll be hard pressed to distinguish between them.
In terms of the gameplay, it’s all about the Free Spins feature where Fisherman Wilds collect fish money symbols (worth up to 1,000 times your total bet). Every 4th Fisherman Wild will also retrigger the feature to give you more free spins and increase the fish money multiplier, up to 10x.
Now, Big Bass Bonanza 1000 offers much bigger max win potential than it’s predecessors, to the tune of 20,000 times your total bet. If you compare to Big Bass Bonanza and Big Bass Splash, it’s significantly more. Below, I’ve added a table comparing the RTP rate, max win potential, hit frequency rate and max win probability for Big Bass Bonanza 1000 and the 2 most popular Big Bass slots:
Slot Game | RTP | Hit Frequency % | Max Win | Max Win Probability |
---|---|---|---|---|
Big Bass Bonanza 1000 | 96.51% | 13.19% | 20000 | 1 in 6,366,645 spins |
Big Bass Bonanza | 96.71% | 13% | 2100 | 1 in 3,880,481 spins |
Big Bass Splash | 96.71% | 13.66% | 50000 | 1 in 3,086,876 spins |
The chances of winning 20,000 times your total bet is a lot lower in the 1000 version but the max win potential is 9.52 times higher than in Big Bass Bonanza and 4 times higher than in Big Bass Splash.
That said, Big Bass Bonanza 1000 offers the highest win potential of any Big Bass slots. Well, Big Bass Hold & Spinner Megaways also comes with 20,000 x bet max wins with the max win probability at 1 in 1,496,522 spins.
To summarise, the Big Bass Bonanza 1000 slot offers big win potential with a high RTP rate but the gameplay is the same as other games in the series. I would have hoped that Pragmatic Play would have added another bonus feature or twist to keep things fresh and exciting. I’m not too sure they will be too many no wager free spins offers on this game though due to the high max win potential.
