Released in June 2025, Big Bass Boxing Bonus Round marks the 26th title in the hugely popular Big Bass series — and this time, the fisherman swapped his rod for boxing gloves. Developed by Reel Kingdom in collaboration with Pragmatic Play, this instalment retains familiar mechanics, including cash-collecting Wilds, progressive multipliers, and the unmistakable Big Bass rhythm.
What’s new is the setting — a packed boxing arena, heavy floodlights illuminating the boxing ring, cheering crowds, and an upbeat soundtrack. The friendly fisherman takes centre stage, but now he’s landing right and left hooks instead of reeling in fish on his rod and hook.
Technical
Big Bass Boxing Bonus Round continues with the classic 5×3 grid with 10 fixed paylines. It’s a highly volatile slot, and like the rest of the series, the 5,000x max win can be achieved in the bonus round.
The slot is available on desktop and mobile devices from 10p to £250 per spin. The default RTP is 96.50%, which places it above the usual benchmark and lends it more appeal for those who value long-term returns.
Design
Big Bass Boxing Bonus Round shifts the action from peaceful lakes to a noisy boxing gym. It’s still got that familiar Big Bass energy, but now the fisherman’s stepping into the ring — gloves on, beard intact, and still very much the main event. The background features ring lights and water-stained walls, with the sounds of a cheering crowd and energetic music replacing the usual calm and serenity of a fishing trip.
It’s a sharp visual pivot that works because it doesn’t try to overhaul everything — it just gives the series a shot of adrenaline. Fishing and fighting shouldn’t go together, but here, they somehow do.
Symbols
The low-paying symbols are your usual card royals — 10 through A — each styled with a sporty edge to match the gym setting. They are frequent, low-impact, and payout between 5x and 10x for five matching symbols on a payline. They do what they’re here to do: fill the grid, keep the reels moving, and soften the gaps between the bigger hits.
The high values introduce the boxing gear. A red boxing glove sits at the top, awarding 200x for five of a kind. Below that are the boxing boots (100x), a jump rope (75x), and a medic kit (50x).
⭐ Special Symbols
Big Bass Boxing Bonus Round has a combination of special symbols. The Money Symbols are classic Big Bass fish, each with a cash value between 2x and 5,000x. These are not available in the base game and are only active during the free spins.
Scatters are golden fish, and landing three or more triggers the bonus round.
There are two Wilds, red and blue boxers. They both collect Money Symbols during the free spins and fill their respective meters to unlock multipliers and retriggers. It’s the same foundation Big Bass fans are familiar with, just dressed up for fight night.
Gameplay & Features
If you’ve played any of the Big Bass slots, you’ll know exactly what’s coming. There are no new mechanics but the features will be familiar.
Wild Symbol
There are two Wilds that only appear during Free Spin. One is the fisherman with blue boxing gloves, the other in red gloves. Both substitute for regular paying symbols but do not replace Scatters or Money Symbols. Their aim is to collect Money Symbols to fill their respective meters.
Money Symbol
Fish symbols play a dual role. In the base game, they are regular pay symbols. However, during the Free Spins, they also act as Money Symbols, with random cash values that are collected by landing a Wild on the same spin. Cash values include: 2x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x, and 5,000x the total bet.
Only one condition — you won’t collect a penny from Money Symbols unless a Wild is present during the Free Spins.
Free Spins & Feature Buy
Free Spins are where the Big Bass Boxing Bonus Round comes into play. Landing 3, 4, or 5 Scatters anywhere on the reels awards 15, 20, or 25 free spins, respectively. If only two scatters land, you get a shot at redemption.
There are two possible rescue moves:
✅ A respin may be triggered if both Scatters are positioned above the bottom of the grid. The Scatters drop down one space while the rest of the reels spin.
✅ A random hook may appear, lift a reel, and drop in a third Scatter. It’s not guaranteed, but it keeps the tension alive when you’re one short.
Once the free spins commence, both blue and red Wilds are active on any spin. If a Wild appears, it collects the value of all Money Symbols on the reels, regardless of their position.
Each Wild colour is tracked by its meter. Every fourth Wild of the same colour retriggers the feature and awards 10+ free spins. Each retrigger also upgrades the multiplier for future collections.
⚡ Feature Buy (Non-UK)
In non-UK markets, you can trigger the Free Spins round for 100x the bet. There’s a Super Free Spins round for 300x the bet— you only need three red or three blue Wilds instead of four for another 10 free spins.
Verdict
Big Bass Boxing Bonus Round is another bizarre entry in the Big Bass franchise — and that’s saying something. The theme is surreal, even by Big Bass standards, but the fact that it still holds together speaks volumes to how reliable the core mechanics have become. Money collections, progressive multipliers, and dual Wilds do most of the work, and they still land well.
There’s nothing new here that hasn’t already been covered in Big Bass Vegas Double Down Deluxe. It’s a full reskin, right down to the meters, modifiers, and max win. However, the dual Wild system remains one of the stronger implementations in the series, and when the multipliers hit, the bonus round delivers.
That said, the volatility is high, and the 5,000x cap might feel somewhat underwhelming for anyone expecting something more ambitious from such a chaotic setup. The theme will split opinion — some will enjoy the absurdity, while others won’t see the point. Either way, it’s not dull. Just don’t expect it to break new ground.
