Best Big Bass Slots (By Features)

These are the best Big Bass slots based on the various features you might prefer. Whether you like big max wins, low volatility or just want to best bonus rounds, these picks will set you on your way. The links will take you to guides on general slots and the best for each feature.

The Top 3 Big Bass Slots and Why

My personal favourite Big Bass game is Amazon Xtreme. Asking the other keen slot players at OLBG what they thought, and the original Big Bass Bonanza gets in as well as Big Bass Hold & Spinner megaways

Big Bass Amazon Xtreme

Big Bass Amazon Xtreme is my go-to due to offering a decent max win potential and lots of little extras in the free spins. There are also some wager free spins offers on the game.

- Chris Taylor, - Your Slots Guide 👍

Big Bass Bonanza

Call me a sucker, but I loved the first one and everything after has been great with its own quirks but there is something special about the original.

- Jenny Mason, - Your Bingo Guide 👍

Big Bass Christmas Bash

Big Bass Christmas Bash is my favourite with the symbols and music used giving it a proper Christmas feel. You can tell that Pragmatic took their time in making this game feel different to other Big Bass games and this makes it even more enjoyable to play.

- Jake Ashton, - Your Betting Odds Guide 👍

Big Bass Hold & Spinner Megaways

It's a bit clunky and not the most attractive version, but a 1200x win has swayed it for me. Outside of that, the two bonus features are equally as good as each other, and it just feels 'edge of your seat' all the time!

• Release Date: 23 June 2022

Released in June 2022, Big Bass Splash has the usual fishing theme but with a Wild West influence. With 5 reels and 10 paylines, it's not hugely different from its predecessors but it does offer a 96.71% RTP rate, high volatility and 5,000 times bet max wins.

A few new features appeared in this October 2022 release of Big Bass Bonanza Keeping it Reel. With 5 reels and 10 paylines, the volatility is high but the RTP rate is 96.07%. To compensate, there are 10,000 times bet max wins on offer. One thing I like is that it's cheerful and upbeat compared to previous Big Bass slots. 

7. Bigger Bass Blizzard

Bigger Bass Blizzard Slot

Rating: 3.4/5

• RTP: 96.08%
• Max Win: 4,000x
• Volatility: High
• Stakes: 12p to £5
• Release Date: 28 November 2022

Staying away from a specific Christmas version in 2022, Pragmatic Play just chucked in snow and lots of it in Bigger Bass Blizzard. With fluffy white stuff, it's a snowy reskin of the Bigger Bass Bonanza game. It comes with a 96.08% RTP rate though but with 4,000 times bet max wins. 

8. Club Tropicana

Club Tropicana Slot

Rating: 3.6/5

• RTP: 96.08%
• Max Win: 4,000x
• Volatility: High
• Stakes: 12p to £5
• Release Date: 9 February 2023

Released in February 2023, Club Tropicana isn't the name of Wham's iconic song but a party-inspired slot where cocktails, sunshine and big wins are guaranteed (see what I did there?). With 5 reels and 12 paylines, Pragmatic Play's favourite fisherman heads to a tropical island to become a cocktail maker. Sporting Aviator-style sunglasses, a Hawaiian shirt and a lot of chest hair, it's all about the free spins where Alan Wilds collect Money symbols for extra free spins and Money symbol multipliers. This can lead to 4,000 times bet max wins. 

9. Big Bass Hold & Spinner

Big Bass Hold & Spinner Slot

Rating: 4/5

• RTP: 96.07%
• Max Win: 10,000x
• Volatility: High

• Release Date: 27 March 2023

The Hold and Spinner mechanic in the Big Bass Hold & Spinner slot is a cracker with 2 bonus features offering a nice variation from what has been released previously. With a 96.07% RTP rate, the volatility is very high but it does come with big win potential of 10,000 times your total bet per spin. 

10. Big Bass Amazon Xtreme

Big Bass Amazon Xtreme Slot

• RTP: 96.07%
• Max Win: 10,000x
• Volatility: Very High
• Stakes: 10p to £5
• Release Date: 19 June 2023

The first time I saw Pragmatic Play's fisherman go off track a little in the Big Bass series is in Big Bass Amazon Xtreme. Set in the Amazon guaranteeing extreme fishing action, this very high volatility slot game benefits from Money Symbols worth up to 1,000 x bet which are subject to a random multiplier up to 50x in the base game. In the Free Spins feature, there are random extras as well as 8 levels where you'll win extra free spins and a Money symbols multiplier up to 50x. This can lead to 10,000 times bet max wins. 

11. Big Bass Hold & Spinner Megaways

Big Bass Hold & Spinner Megaways Slot

• RTP: 96.70%
• Max Win: 20,000x
• Volatility: High
• Stakes: 20p to £5
• Release Date: 28 August 2023

My favourite Big Bass game to date, although a little less easy on the eye and a bit clunky, the extension to Big Bass Hold and Spinner Megaways was a masterstroke with double feature options. With a 96.7% RTP rate, it has 6 reels and up to 147,465 ways to win. Importantly, it's the highest paying Big Bass slot game with 20,000 times bet max wins. 

12. Big Bass Halloween

Big Bass Halloween Slot

Rating: 2.6/5

• RTP: 96.06%
• Max Win: 2,100x
• Volatility: Medium-High
• Stakes: 10p to £5
• Release Date: 23 October 2023

It has to happen, Pragmatic Play keeps coming with holiday season versions of the Big Bass slot classic and this time, its Halloween for a spooky fishing trip. I dreaded playing the Big Bass Halloween slot and it was exactly what I expected it to be. Basically, it's a spooky version of the original Big Bass Bonanza as it offers the same max win potential but a much lower RTP rate of 96.06%. 

13. Big Bass Christmas Bash

Big Bass Christmas Bash Slot

Rating: 3.3/5

• RTP: 96.71%

• Stakes: 10p to £5
• Release Date: 23 November 2023

Christmas is back with the Big Bass slot theme as Big Bass Christmas Bash was unleashed in time for the 2023 festive period. When you are feeling festive and want to inject some of that into your slot play, Big Bass Christmas Bash slot serves it up.

Will the ideas ever end? The Big Bass series get an update in Big Bass Floats My Boat. There isn't a lot of difference in this game but it keep the series tripping along with the first Big Bass release of 2024. Max win potential can reach 5,000 times your total bet. 

15. Big Bass Day at the Races

Big Bass Day at the Races Slot

Rating: 4.1/5

• RTP: 96.07%
• Max Win: 10,000x
• Volatility: Very High
• Stakes: 10p to £5
• Release Date: 7 March 2024

Just in time for the Cheltenham Festival, Pragmatic Play merge Big Bass with horse racing for the Big Bass Day at the Races slot. A reskin of the Big Bass Amazon Xtreme game, I like how Pragmatic has managed to combine slots with what OLBG is known for (horse racing). High volatility, it comes with 10,000 times bet max win potential. 

16. Big Bass Secrets of the Golden Lake

Big Bass Secrets of the Golden Lake Slot

• RTP: 96.07%
• Max Win: 5,000x
• Volatility: Very High
• Stakes: 10p to £5
• Release Date: 8 April 2024

Released in April 2024, Big Bass Secrets of the Golden Lake is another hint at the future of Big Bass slot games. It combines the original concept with an Arthurian Legend twist. With Day at the Races' previous merging with horse racing, are we witnessing the roadmap where every theme is open game for Big Bass collaborations? I think so.

Released in February 2025, you have the Bigger Bass Splash slot game. With 5 reels and 10 paylines, it has a party twist on the classic fishing theme but has all the same gameplay as Bigger Bass Bonanza and Big Bass Splash. With a 96.5% RTP rate and 5,000 times bet max wins, I would have hoped that Pragmatic Play went in a different direction to kick off 2025 in style. 

24. Big Bass Return to the Races

Big Bass Return to the Races Slot

• RTP: 96.07%

Big Bass Bonanza Max Wins Comparison?

What is the most you can win on Big Bass Bonanza? Well, that depends on the maximum win levels and the stake. Here is a table with all the details on staking and max win levels.

Max win potential ranges from 2,100 x bet at the bottom end with the debut Big Bass Bonanza, Christmas Big Bass Bonanza and most recently Big Bass Halloween, right up to the largest Big Bass max win of 25,000 x bet available on Big Bass Splash 1000.

Big Bass RTPs (Return to Player)

Not all Big Bass slot games have the same return to player, with the range covering the highest at initial release of Big Bass Bonanza at 96.71% with the lowest in some of the more recent releases like Big Bass Amazon Xtreme and Big Bass Halloween.

Big Bass Volatility

Big Bass Bonanza, the original release in 2020, came with a self score of 4/5 (Medium-High) for volatility. Since then, only 4 further games have had that score with the remainder having the highest volatility score of 5/5. 

In my opinion, the difference is barely detectable and I'd be surprised if any slot player of any experience would be able to differentiate between one game or another.
