Which Big Bass Slot is the Best?

What a question! With so many to choose from, varying RTP rates, bonus features, volatility and max wins, how can you choose? We asked our slots experts at OLBG about their favourite Big Bass title.

Chris Taylor

Big Bass Splash

Big Bass Splash is my go-to due to offering a high RTP rate, decent max win potential and lots of little extras in the free spins. There's also plenty of no wager free spins offers on the game.

- Chris Taylor, The King of Slots

Jenny Mason

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, Queen of Bingo

Jake Ashton

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, Senior News Editor

Steve Madgwick

Big Bass Hold & Spinner Megaways

It's a bit clunky and not the most attractive version, but I've had some good wins, and the two bonus features are equally as good as each other. Not to mention I've had a pretty nice 1200 x bet win once.

- Steve Madgwick, Editor-In-Chief

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.

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.

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.

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.

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.
