Introduction – Step Into the Ring with Big Bass Boxing
We’ve tested dozens of Big Bass slots over the years at UK casino sites — from the chill vibes of Big Bass Bonanza to the fiery chaos of Big Bass Hold & Spinner Megaways. But this? This is something else entirely. Big Bass Boxing Bonus Round throws fishing and boxing into the same ring and somehow makes it work.
As long-time reviewers of UK slots and fans of Reel Kingdom’s quirky designs, we spent over 400 spins on this title to bring you a first-hand, honest, and fully tested review. Here’s what we learned — the good, the frustrating, and everything in between.
Game Overview
Who Made Big Bass Boxing Bonus Round?
Launched in June 2025 by Reel Kingdom in collaboration with Pragmatic Play, this is the 26th entry in the Big Bass franchise. If you’re familiar with earlier versions, you’ll notice familiar mechanics — but with added punch (literally).
Theme, Graphics & Sound Design
A boxing ring. Fishing symbols. Thumping gym music. It shouldn’t work, but it does. The visuals are vibrant and dynamic — flashing lights, animated boxer fish, and slick interface transitions. The sound cues during bonus rounds add adrenaline — something many earlier Big Bass games lacked.
🎧 Try it with headphones — the bass drop (pun intended) when a bonus hits is oddly satisfying.

The animated fish-boxer character reacts to your wins and losses — giving the game a more immersive, personality-driven experience that older titles lacked.

Final Verdict: Our Experience
We spent nearly two hours testing Big Bass Boxing and walked away impressed — and slightly bruised. While our biggest win was 388x, the sheer tension of retriggering multipliers made every bonus feel like a title fight.
It’s not for the faint-hearted, but if you’re into high volatility slots with fresh mechanics, this is easily one of the best Big Bass entries in the series.
Our Rating: ★ 4.8/5
We’ve rated Big Bass Boxing Bonus Round 4.8 out of 5 based on its bonus features, RTP, mobile performance, and overall entertainment value. While it’s a great choice for fans of high-volatility slots with action-packed themes, it may not suit those looking for frequent low-risk wins.
