Big Bass Boxing Bonus Round Slot RTP, Details & Wager Limits

Pragmatic Play built the Big Bass Boxing Bonus Round slot game on a classic 5-reel, 3-row engine. The 10 paylines are low compared to many new slots. Create winners by landing 3, 4, or 5 matching symbols (or wilds) from left to right in a payline, starting from the leftmost reel.

You can get your virtual gloves on at bet levels of between 10p and £375 per spin (£5 max at UK online casinos). That minimum bet is low compared to many online slots, making it a good choice if you’re playing with a small bankroll. Turbo spin and autoplay options are available if you’re in a territory where they are allowed. That doesn’t include the UK.

Pragmatic Play sets the Big Bass Boxing Bonus Round RTP at 96.50%, which is better than average. For more slots that deliver plenty of bang for your buck, check out the best RTP slots. The action here is volatile. On a scale of 1 to 5, the variance scores a maximum of 5. The Big Bass Boxing Bonus Round max win is 5,000x. Perfectly adequate but nothing special, and a distance behind the big progressive jackpot slots.

Big Bass Boxing Bonus Round Theme—Go Toe-to-Toe with a Pair of Cartoon Fighters

The reels in the Big Bass Boxing Bonus Round slot are filled with classic boxing-themed symbols. Joining the lower value royals, higher paying symbols include a medical kit, skipping rope, boxing boots, and gloves. This being a Big Bass slot, there are also fish symbols that sit a bit uncomfortably next to the others.

During the feature round, two wilds join the action. There’s a bearded fighter in blue trunks and a baldie sporting red. The latter has a cartoonish look of Britain’s most notorious prisoner, Charles Bronson!

With the bright lights of a boxing venue in the background, the colourful symbols stand out nicely against the dark backdrop.

The soundtrack offers little hints at the Rocky theme and is nicely done. The cartoonish design isn’t sophisticated, but I like what Pragmatic Play has done here.

This is what the paytable delivers:

Big Bass Boxing Bonus Round Mobile Slot

The Big Bass Boxing Bonus Round mobile casino slot is available to play on tablets and smartphones. The simple design and straightforward gameplay are ideally suited to mobile play. I tried the game on Android and iOS devices and found the playing experience straightforward with either.

Big Bass Boxing Bonus Round Bonus Features

Free spins top the bill of the Big Bass Boxing Bonus Round bonus features. Catch fish symbols to win instant cash prizes and collect wild symbols to add more spins and bring multipliers into play. As usual, I recommend a few spins of the Big Bass Boxing Bonus Round demo slot. It’s one of a huge collection of free play slots available here.

Free Spins

Land 3, 4, or 5 scatter symbols on the same spin and you’ll receive 15, 20, or 25 free spins. Land 2 scatters and you could benefit from a respin, or a hook can bring in a third scatter to activate the bonus.

The gameplay is different during the free spins round. Keep a special eye out for the fish symbols. Each fish symbol shows a monetary value. These range from 2x up to 5,000x.

Land a wild during the free spins, and the money values attached to any fish on the reels on that spin are awarded as instant prizes.

Each red or blue wild that lands is added to a meter. Furthermore, every fourth wild of one colour that is collected adds another 10 free spins to your total. It also brings a multiplier that boosts the value of the Fish Money prizes. The first re-trigger delivers a 2x multiplier, followed by 3x and 10x for subsequent re-triggers.

If you have a spin where a wild lands but no fish, you could receive a Camera Spin. This drops fish symbols into random positions on the grid. You could also see a Knock Out animation. This keeps the fish in place but moves new symbols into all the other positions. A new payout consideration follows.

If there are fish symbols but no wild, a hook can randomly appear to drag a wild onto the reels.

Bonus Buy and Ante Bet (Unavailable in the UK)

Players at Big Bass Boxing Bonus Round casinos in some jurisdictions, but not the UK, can activate Ante Bet. Take your stake from the standard 10 coins to 15 coins per spin, and extra scatters are added, boosting your chances of triggering the feature.

Alternatively, pay 100x for a standard free spins trigger or 300x for the Super Free Spins. Additionally, in this round, you need 3 rather than 4 wilds of any colour for a re-trigger.

Big Bass Boxing Bonus Round Verdict: This Fight Club Lacks a Bit of Punch

3.4/5
Big Bass Boxing Bonus Round Slot
The fishing/boxing theme is a bit weird. If you can see past that, there’s some decent action in Big Bass Boxing Bonus Round, especially if you trigger the free spins feature.

The latest addition to the Big Bass franchise ticks all the usual boxes. The fish collect feature is a staple of the series, and it’s the centrepiece of the free spins feature here. It’s pretty good, too. Just don’t expect much in the way of variety here, as it’s the only bonus you’ll get.

The cartoonish design is just what you’d expect from a Big Bass slot and is fine. Moreover, the stats are decent too with a better than average return to player rate and a 5,000x max win.

It’s not very original, and the gameplay is limited. Big Bass Boxing Bonus Round might not be an undisputed champion of the world, but it is a competent performer if you like this series or the boxing theme.

If you like this series but want more features, check out Big Bass Hold & Spinner Megaways from Pragmatic Play. It comes with tumbling reels, mystery symbols, free spins, streak re-spins, and a 20,000x maximum win. Another option is Iron Dog Studio’s Loot Crab.

Club Tropicana by Pragmatic Play is a real party animal among slots. If you’re up for tropical bar vibes and cocktails, this is the real thing for you.
