The reels in Big Bass Boxing Bonus Round sit inside a bird’s-eye view of a boxing ring. The canvas is black, which makes the symbols pop in a way that most Big Bass grids don’t. Strobe lights pulse on either side, blue and red, matching the colour coding of the two corner fighters. A crowd fills the seats in the background, silhouetted against the venue lighting. Someone at Reel Kingdom put real thought into this one. The theme lands harder than most Big Bass departures, and the visual execution earns the setting.
The fish are still here, of course. In this slot, they wear boxing helmets and carry cash values from 2x to 5,000x stake. They are both the scatter and the money symbol. Three or more land anywhere to trigger 15, 20, or 25 free spins, and during the bonus each one pays out its displayed value when a wild boxer collects it.
Two wild symbols run during free spins. A blue corner boxer and a red corner boxer each feed their own independent collection meter. Every fourth wild of either colour collected retriggers 10 more free spins and upgrades that colour’s fish multiplier. The steps are 2x on the second level, 3x on the third, and 10x on the fourth. After the fourth level, neither meter can retrigger again. Both meters run simultaneously, so both can progress if both wilds land frequently in the same round.
Free spins trigger on 3, 4, or 5 scatter symbols anywhere on the reels, awarding 15, 20, or 25 spins, respectively. The round can extend significantly via retriggers. Each meter can fire four times, meaning up to 40 additional spins are theoretically available from each colour. The fish money symbols collected during the round pay out their displayed values at the end, multiplied by whichever level the relevant meter has reached.
Three modifiers can fire randomly during free spins.
Ante Bet increases the total stake by 50%, raising scatter frequency in exchange for a higher cost per spin. It also disables the buy feature while active. Buy Free Spins costs 100x total bet and guarantees at least 3 scatter symbols on the triggering spin. Buy Super Free Spins costs 300x total bet and guarantees at least 3 scatters; in this mode the retrigger threshold drops from 4 wilds to 3 wilds of either colour, making both meters easier to advance.
Big Bass Boxing Bonus Round runs on 5 reels, 3 rows, and 10 fixed paylines. Wins pay left to right from reel 1; only the highest win per line is paid. The fish money symbol is both the scatter that triggers the bonus and the money symbol that pays out during it. The value displayed beneath each fish on the reels is what gets collected when a wild boxer lands on the same spin.
Bets run from $0.10 to $375 per spin. RTP is 96.50% in standard play, Ante Bet mode, and both buy feature modes, confirmed in the game rules screen. Pragmatic Play also offers 95.5% and 94.5% operator variants, so the info panel at your chosen site is worth checking before you play. High volatility. Max win 5,000x stake. A few rounds of free play will show how the two meters progress at different rates depending on which corner’s wild lands more frequently.

Big Bass Boxing Bonus Round is a confident thematic entry in a series that has tried plenty of settings. The boxing ring is one of the strongest visual shifts the franchise has produced, the dual-meter free spins create real suspense when both corners start connecting, and the random modifiers add welcome unpredictability to a bonus format that can otherwise feel repetitive. The honest caveat is that the underlying structure is identical to Big Bass Vegas Double Down Deluxe. This is a new coat of paint on an existing chassis.
The buy-in was $300. That is 300x a $1 stake for the Super Free Spins option, which guarantees a feature trigger and drops the retrigger threshold to 3 wilds per colour. Standard play before pulling the trigger was what 10-payline high-volatility slots tend to deliver. Occasional small wins, longer patches of nothing, and the sense that the session lives or dies by what happens in the bonus.
Our free spins started badly. For the first half of the 25 spins neither meter moved, the fish values collecting were modest, and the balance of probability was pointing toward a significant loss on the buy. Then the red corner woke up. A cartoon animation fired when the fourth red wild locked in. The red boxer landing a clean punch on the blue, the x2 multiplier confirmed, and 10 more spins added. The Hook feature fired shortly after, pulling a reel up to drop one more red boxer wild onto the canvas. By the close, we had played 25 spins in total and returned $113.60, roughly 113x the stake from a round that had looked dead at halfway. It did not cover the $300 buy. As a session result, it is on the losing side. As an illustration of the format doing what it is designed to do, it captured it exactly.
This review lands at an honest place. Big Bass Boxing Bonus Round is a direct reskin of Big Bass Vegas Double Down Deluxe. The dual wild system, two independent meters, 4-wild retrigger threshold in standard mode, and the multiplier steps of 2x, 3x, and 10x are all unchanged. If you know that game, you know this one. What Boxing adds is a stronger theme, a more focused visual identity, and the 3-wild retrigger threshold in the Super Free Spins buy. That last point is the only structural difference between the two.
The original Big Bass Bonanza runs a simpler single-meter format at a higher RTP of 96.71% and a lower max win of 2,100x. It is the better value entry if you want the core format without the dual-meter complexity. Big Bass Raceday Repeat moves to 6 reels and, as suggested by its name, showcases a horse-racing theme, which significantly alters its overall vibe. Big Bass Halloween 3 is another reskin of the same Vegas Double Down engine under a horror theme, effectively a third version of the same dual-meter slot.
Players who enjoy the Big Bass free spins format and want the most thematically distinct version of the dual-meter setup will find Boxing delivers on the setting. The ring is well made, the fighter animations add genuine character, and the two-corner tension in the bonus is involving when both meters are live. Players who have already spent time with Big Bass Vegas Double Down Deluxe are playing the same slot in a different venue.
15 free spins triggered with both corners in play. The blue and red corners each feed their own collection meter during the round.
