Big Bass Boxing Bonus Round Review
If you thought bringing your fishing gear to a boxing match sounds strange, well, that’s exactly what you’ll be doing in Reel Kingdom’s Big Bass Boxing Bonus Round slot. We can reveal up front that this is a reskin of another incongruent title, namely Big Bass Vegas Double Down Deluxe. The math model and the features are the same, but this time you get to see the bearded fisherman duke it out with a mean-looking opponent in the ring.
You start by choosing your bet level between €0.1 to €250 per spin, catering to both penny punters and high-rolling daredevils. Big Bass Boxing Bonus Round plays out on a 5x3 grid with 10 paylines, and winning combinations align from the leftmost reel towards the right. The premium symbols, consisting of boxing gloves, boxing shoes, a skipping rope, a first-aid kit, and various fish, award between 20x and 200x your stake for 5 of a kind wins. The royals pay 5x to 10x your stake for the same.

Wild symbols only appear during free spins in Big Bass Boxing Bonus Round slot, substituting for regular pay symbols while also collecting all fish money symbol prizes in view. The bearded fisherman and his mustache-sporting opponent figure on the blue and red wilds, respectively, and you get to see them knock each other out after each bonus retrigger. They both have their own bonus trail to fill, awarding extra free spins and upgrading their respective money symbol multipliers.
Big Bass Boxing Bonus Round is a highly volatile game, scoring 5 out of 5 on the in-game scale. As usual, you can expect the largest payouts to come in the bonus round, including the game’s 5,000x max win. With a hit rate of 12.98 %, expect plenty of dead spins between each base game win. The good news is that the bonus round hits around every 113 spins on average, and that’s without the Ante Bet turned on. The top-tier RTP of 96.5 % is well above average, and the win cap hit frequency is a decent 1 in 2,544,391 spins.
Big Bass Boxing Bonus Round Features
Players who’ve played the original game will not find anything new in the feature department of Big Bass Boxing Bonus Round Reel Kingdom. However, we’ll present a detailed overview below for new readers and players.
Ante Bet (not UK)
The bonus round hit frequency in Big Bass Boxing Bonus Round is already pretty solid, clocking in at 1 in 113 spins. However, you can increase it further (by an unspecified amount) if you turn on the Ante Bet feature. This will cost you 50 % extra per spin, but keep in mind that the Ante Bet feature is not available in all jurisdictions.
Big Bass Boxing Bonus Round Free Spins
The Bonus Round triggers when you land 3, 4, or 5 scatter symbols on the same base game spin, awarding 15, 20, or 25 free spins, respectively. Landing only 2 scatters can sometimes trigger a respin or hook that delivers the crucial third scatter needed to activate the bonus round. This is a randomly triggered feature, so there is no guarantee.
Money symbols are collected by two unique Wild Collector symbols during the bonus round, and the money symbol values range from 2x to 5,000x your stake. The blue and red Wild collector symbols are themselves collected in their respective meters above and below the grid. Every time 4 wilds of the same color are collected, you win +10 extra free spins while also increasing the win multiplier for money symbols collected by the relevant Wild Collector.
The multiplier for either of the meters increases to x2 on the first retrigger, x3 on the second retrigger, and x10 on the third retrigger. Once the x10 multiplier has been unlocked, no more scatter symbols appear, meaning you cannot win more extra free spins nor increase the win multiplier further. In addition, here is an overview of the random features that can trigger during the free spins round:
- Camera Spin - if wild collectors are present without any fish to collect, fish may appear randomly at the end of the free spin.
- Hook - if money fish symbols are present without any wilds to collect them, a hook may bring at least one wild collector symbol into view.
- Knock Out - if wilds are present without money fish symbols, symbols may be turned into something else without affecting the wilds.
Big Bass Boxing Bonus Round Bonus Buy (not UK)
Eligible players can purchase the bonus round for 100x the stake, guaranteeing at least 3 triggering scatters on the spin that follows. Alternatively, you can pay 300x your stake to get the super bonus round, which requires only 3 collected wilds of the same color to upgrade the win multiplier and award extra free spins. It’s worth repeating that the organic bonus round hit frequency is 1 in 113 spins, which is well above the industry average.
How to Play Big Bass Boxing Bonus Round?
Big Bass Boxing Bonus Round does not ask you to do anything clever once the reels are moving. There are no decisions to make mid-spin and no moments where player input changes the outcome. The only part that really matters happens before you press Spin, when you figure out which version you are playing and what the game actually allows you to access.
1Check what the game allows in your region: Depending on where you play, Big Bass Boxing Bonus Round may load without Ante Bet or Bonus Buy. If they are missing, that is simply how the game is regulated in your jurisdiction.
2Handle the casino formalities first: Log in, register if needed, and clear any verification steps early. This avoids breaking the session later for administrative reasons.
3Bring a balance suited for waiting: The base game is not particularly active and can burn through spins quietly. Small, short-session balances tend to vanish before the slot shows anything of interest.
4Set a stake and accept its role: Choose a bet between €0.1 and €250 per spin. Once set, this value defines everything the slot does, from base wins to the free spins payout.
5Understand how free spins are accessed: In regions without Ante Bet or Bonus Buy, free spins arrive only through regular play. There is no pacing option and no way to influence when they land.
6Let the slot run its course: After that, the game plays itself. Spins, free spins, upgrades, and payouts all resolve automatically, for better or worse.
Big Bass Boxing Bonus Round Strategy
Big Bass Boxing Bonus Round is not a game that rewards clever timing or micro-decisions. Once a spin is running, everything unfolds on its own. The only real control you have sits outside the reels, in how you structure the session and how much patience you bring to it.
- Accept from the start that the base game is mostly dead air and plan your balance around waiting, not winning.
- Pick a stake you are comfortable repeating for a long stretch and resist the urge to adjust it after empty spins.
- Treat Ante Bet as a pacing option rather than a value tool, since it only changes how quickly you reach the feature.
- Use Bonus Buy if you want to see the free spins mechanics without committing to a long base game grind, not as a shortcut to profit.
- Ignore scatter near-misses, as they have no bearing on when the next free spins round appears.
- Judge the session as a whole rather than reacting to a single bonus round, since outcomes vary widely from feature to feature.
Theme & Graphics
The Big Bass Boxing Bonus Round slot offers a rather incongruent and odd experience, mixing the well-known and popular fishing theme with boxing. You take your seat in the audience with the 5x3-sized grid effectively blocking any view of the ring. The reels are filled with fish wearing headgear, as well as boxing gloves, boxing shoes, and skipping ropes. The two Wild symbols, featuring the bearded fisherman and his bald opponent, trigger knock-out animations with each bonus round retrigger.

Our Verdict
Personally, I was never fully on board the whole Big Bass bandwagon, and I still feel that the series has been hyped out of proportion. Of course, this is only possible because a large amount of players enjoy these games, but the initial charm is long gone, at least in my humble opinion. Reel Kingdom is now milking its sole claim to fame to such a shameless degree that I almost blush on their behalf with each new installment.
Big Bass Boxing Bonus Round is not only yet another attempt at mixing two incongruent themes, but it’s also a straight-up reskin of Big Bass Vegas Double Down Deluxe (quite a mouthful of a title). I mean, it’s not like players are lacking in alternatives when it comes to Big Bass slots, and it would be appreciated if Reel Kingdom would limit new installments to whenever they’re able to come up with something original.
Instead of churning out weird themes and remakes, why not make a real effort to expand on the core concept and take this series to the next level? There is plenty of room for improvement in the base game, which is rather tedious in most Big Bass installments, including Big Bass Boxing Bonus Round. The best thing about this release is the knock-out animations you get per free spins retrigger, which are kind of entertaining and hit the right spot for the theme (except for the fishing part).
Of course, it’s always nice to have two Wild collectors and bonus trails, and the 3 bonus round modifiers come in handy when you least expect it. The bonus round hit rate is also quite favorable in Big Bass Boxing Bonus Round slot, even without the Ante Bet active. The 5,000x max win is not too shabby either, and it comes with a decent hit rate as well. If you’re a fan of, well, fishing and boxing, this is a good alternative to the more flashy Big Bass Vegas Double Down Deluxe.
