Big Bass Bonanza Slot Review

Home › Slots › Big Bass Bonanza

Last updated: June 2026

The Big Bass Bonanza slot by Reel Kingdom and Pragmatic Play is the fishing game that launched a huge franchise. The fisherman wild reels in cash-value fish during the free spins, and collecting them boosts a multiplier up to 10x. It runs a 96.71% RTP, is high volatility, and caps at 2,100x. Here is the honest guide to how the bonus works, the wider series, and where to play.

Our score: 4.0/5. A genuinely fun, well-paced fishing slot with a satisfying collect-and-multiply bonus and a solid 96.71% RTP. Marked down for a modest 2,100x ceiling on the original, when the later franchise entries pay far more.

Big Bass Bonanza at a glance

What is the Big Bass Bonanza slot?

Big Bass Bonanza is the fishing slot that spawned a dynasty, made by Reel Kingdom and distributed by Pragmatic Play in December 2020. The cheerful angler theme, the money-fish symbols and the simple, satisfying collect mechanic made it a runaway hit, and it has since grown into one of the biggest slot franchises around. It is a straightforward 5-reel, 3-row, 10-payline game, easy to pick up and well-paced.

How Big Bass Bonanza works

The base game is simple; the free spins are the star. In normal play you are mainly fishing for 3 or more scatters to trigger the bonus. The money symbols, fish carrying cash values from 2x up to 2,000x your stake, only pay during the free spins, so the base game is mostly a build-up.

In the free spins, the fisherman becomes the key. The fisherman is a wild, and each time he lands he collects the value of every money-fish on the screen. Collect enough fish and you both retrigger more spins and boost a multiplier: every fourth fisherman collected adds 10 more free spins and steps the money-symbol multiplier up, to 2x at the first step, 3x at the second, and 10x at the third. Stack a screen of high-value fish with a 10x collector and the wins add up fast.

Big Bass Bonanza RTP and max win

The default RTP is a healthy 96.71%, a touch above average, though Pragmatic ships lower versions that casinos can run, so check the info screen. Volatility is high, with the value concentrated in the free-spins collect mechanic, so expect cold base-game runs between bonuses.

The maximum win on the original is 2,100x your stake. That is honest but modest by modern standards, and it is the original’s main limitation. The good news is the franchise fixes it: later entries like Big Bass Splash (5,000x) and Big Bass Amazon Xtreme (10,000x) raise the ceiling significantly. So if you want a bigger top end, the sequels deliver it.

The Big Bass franchise

Big Bass Bonanza became a series, fast. The notable entries, with their higher caps, include:

There is also a Big Bass Bonanza Megaways, plus seasonal versions like Big Bass Halloween and Big Bass Christmas. The core collect-and-multiply mechanic carries through them all; the later ones simply raise the stakes.

Where to play Big Bass Bonanza for real money

Big Bass Bonanza is available wherever Pragmatic Play is licensed, including regulated US states (New Jersey, Pennsylvania, Michigan), the UK, Europe and crypto casinos. Pragmatic exited US social and sweepstakes casinos, so the US route is a regulated real-money operator. The casinos below carry Pragmatic. Scores are out of 10.

Chip’s verdict on Big Bass Bonanza

Big Bass Bonanza is one of those games that just works. The fishing theme is daft and charming, the collect mechanic is genuinely satisfying when the fisherman reels in a screen full of fish, and the 96.71% RTP is better than many big-name slots. It is no surprise it became a franchise.

The one honest knock is the 2,100x ceiling on the original, which feels low next to modern slots and even its own sequels. If you love the original’s pace, play it and enjoy it; if you want a bigger top end, Big Bass Splash or Amazon Xtreme give you the same fun with more upside. Either way, check the RTP and bankroll for the high volatility. Score it 4.0 out of 5. See how we rate.

Frequently asked questions

What is the RTP of Big Bass Bonanza?

The default RTP is 96.71%, a touch above average, though Pragmatic ships lower versions that casinos can run. Check the in-game info screen for the figure where you play.

What is the max win on Big Bass Bonanza?

The original caps at 2,100x your stake, which is modest. Later franchise entries pay more: Big Bass Splash caps at 5,000x and Big Bass Amazon Xtreme at 10,000x.

How do the Big Bass Bonanza free spins work?

Land 3, 4 or 5 scatters for 10, 15 or 20 free spins. The fisherman wild collects the cash values on money-fish symbols, and every fourth fisherman collected adds 10 spins and raises the multiplier to 2x, then 3x, then 10x.

Do the money symbols pay in the base game?

No. The money-fish symbols only pay during the free spins, when the fisherman collects them. In the base game they are inactive, so the base game is mainly about triggering the bonus.

Is Big Bass Bonanza a Megaways slot?

No. The original is a fixed 5-reel, 3-row, 10-payline game. There is a separate Big Bass Bonanza Megaways title if you want the shifting-ways version.

Who makes Big Bass Bonanza?

It is made by Reel Kingdom and distributed by Pragmatic Play, released in December 2020. The franchise includes Bigger Bass Bonanza, Big Bass Splash and Big Bass Amazon Xtreme.
