Five reels, 10 lines, a fisherman and some fish with cash values printed on them. Big Bass Bonanza came out in December 2020 and spawned a long run of Pragmatic Play sequels.
It's a game of two halves, and one half is boring. The base game is plain line spins with no modifiers. All the interest lives in free spins, where wild fishermen collect the money on every fish showing.
Spin Score: 6.9. That's an odd shape. The RTP factor is excellent at 9.1, because Pragmatic lists 96.71%. Then the base game scores 3 and the max win, 2,100x per Bigwinboard, scores 4.5. Great maths, thin game.

Free spins round: Free spins where the fisherman wild collects every fish money symbol on screen, and every fourth wild retriggers with 2x, 3x then 10x multipliers on collections.
Base game: The base game is plain 10-line spins with no modifiers; nearly all value sits in the free spins.

Slots that share what makes Big Bass Bonanza what it is, in Spin Score order, at most two per provider. Big Bass Bonanza itself is scored in the spec sheet above. Spin Score = 40% RTP, 15% max win, 30% free spins round, 15% base game. How we score
The benchmark for collect-style bonuses, and it tops this list with an 8.5. The Money Cart round scores a perfect 10: three respins, sticky symbols, and Collector, Payer, Sniper and Necromancer characters that collect, add and multiply values while the grid grows. It's Big Bass's fish-collecting idea taken much further, with a 50,000x ceiling. The base game is quiet too (5). Watch the RTP: 96.4% per slotcatalog, but Relax lists a 90% German version. Bonus buy is 100x and not sold in the UK.

What it is: A 5x4, 40-line western slot built around the Money Cart bonus: a sticky-symbol respin round where special characters collect, add and multiply values.
Free spins round: The Money Cart bonus is a 3-respin hold-and-win round with Collector, Payer, Sniper and Necromancer symbols, and the grid grows when reels fill.
Base game: Two scatters trigger a respin feature with a building multiplier; outside that, base spins are mostly quiet.

The last Money Train, and the biggest. The Money Cart bonus scores 10 again, now with more than 20 features including the Arms Dealer, Upgrader, Unlocker and Reset, and a 150,000x max win. It slips below Money Train 2 on RTP: 96.1% per slotcatalog, and Relax shows a UK game ID ending in _92. Very high volatility. If Big Bass's 2,100x ceiling feels low, this is the opposite end of the scale.

The most balanced game here. Fat Banker gets a 7 for its base game, where bullion and multiplier symbols land often and a random Red Car feature adds wilds or safes. That's the thing Big Bass is missing. It has two bonuses: a Fortune Link respin round that collects bullion and multipliers, and free spins where the banker grows by eating money bags. Push Gaming lists 96.43% and 94.45% settings, and a 25,000x highest observed win.

Two very different bonuses earn this a 9 on free spins. Underworld builds per-reel multipliers up to x9,999 that have to be unlocked; Judgement is a hold-and-win drop round with stacking multiplier blocks. The base game is mostly plain cluster results (5). RTP is the weak spot: four settings from 96.24% down to 88.41%, per Bigwinboard. Bonus buys cost 129x for Underworld and 200x for Judgement. Very high volatility, 5 out of 5 on Hacksaw's own meter.

The sequel, and the better Big Bass. Same 10-line layout, same 96.71% top RTP, same plain base game. The free spins round adds up to five random modifiers before it starts, which lifts the bonus score from 7 to 8, and fish values go up to 5,000x. That's why it scores 7.4 against the original's 6.9. There's a 94.6% setting the original doesn't list, and a 100x bonus buy where permitted. If you like Big Bass, play this one.

A gentler alternative. Wolf Gold is medium volatility, and its Money Respin is the money-collect idea in hold-and-win form: six or more moon symbols lock in place and can pay three fixed jackpots, up to the 1,000x Mega for a full grid. It ranks last because free spins are basic (5) and the 96.01% RTP scores only 7. SlotCatalog says lower settings exist but doesn't list them. Max win 2,500x.

How Big Bass Bonanza plays
The base game is a standard 5-reel, 10-line slot. Symbols pay left to right, fish symbols show cash values, and there's nothing else going on. No wilds in the base game, no tumbles, no random features. That's why our editors gave it a 3.
A quick note on the grid. The sources we use confirm 5 reels and 10 lines but neither states the row count, so the spec sheet keeps to what's published.
Volatility is rated 4 out of 5 by Bigwinboard. High, then. That's a lot of swing for a game whose max win is 2,100x, and it's the core problem with Big Bass Bonanza: you get the dry spells of a high-volatility slot without the ceiling that usually comes with them.
Bets run from 0.10 to 250 per spin per Bigwinboard, a wide range. Pick the low end if you're trying it out.
The free spins round: how the fisherman collects
Three to five scatters start 10 to 20 free spins. In the bonus, a fisherman wild can land, and when he does he collects the cash value of every fish symbol on screen.
Then there's the retrigger ladder. Every fourth fisherman collected retriggers the round, and the multiplier on collections steps up: 2x, then 3x, then 10x. A round that reaches the 10x level with fish on screen is where the bigger results come from.
The weak spot is that everything hinges on two things landing together: a fisherman and some fish. Fish with no fisherman pay nothing. A fisherman with no fish pays nothing. So plenty of rounds end with small totals, and the round scores 7 from our editors because of it.
On max win, the sources don't quite agree. Pragmatic's page gives fish values up to 2,000x, while Bigwinboard lists the max win at 2,100x. We use Bigwinboard's figure and say so.
Our sources for this game don't list a bonus buy. Big Bass Splash, the sequel, has one at 100x where it's allowed.
RTP settings and what to check
Pragmatic lists 96.71%, and Bigwinboard adds a 95.67% version. The casino picks which one it runs, and the game looks the same either way.
Open the info screen and read the RTP line before you play. 96.71% puts it in the top ten for RTP among the 105 slots we score, and it's the main reason Big Bass Bonanza scores as high as it does. At 95.67%, most of that advantage is gone.
Keep it in proportion, though. RTP is an average over millions of spins. A 96.71% game still has a negative expected value, and a single session can land far from that number in either direction. The RTP explainer covers why.
Big Bass Bonanza or Big Bass Splash?
Splash. It's not close on our numbers.
Both list 96.71% at the top setting, so they tie on RTP. Both have the same flat base game, scored 3. Splash pulls ahead in two places. First, the bonus: up to five random modifiers can be added before free spins begin, which our editors score 8 against the original's 7. Second, the ceiling, where fish values go up to 5,000x instead of roughly 2,000x. Together that's 7.4 against 6.9.
Bigwinboard rates both 4 out of 5 for volatility, so you're not trading calm for ceiling here, which is unusual for a sequel.
Two small things go the other way. Bigwinboard lists a third, 94.6% setting for Splash, so the info-screen check matters a bit more. And Splash has a 100x bonus buy where permitted. I'd skip the buy. 100x for a round that often pays modestly is a fast way to empty a balance, and it doesn't change the house edge.
Who it suits, and what to play instead
Big Bass Bonanza suits someone who wants a very simple game: spin, wait for scatters, watch the fisherman. Nothing to learn. It doesn't suit anyone who gets bored by long runs of base spins where nothing happens.
If the collect mechanic is what you like, the list below goes from that idea in its plainest form up to Money Train 2, which turns it into a full hold-and-win round. Our hold and win slots ranking covers that style properly.
The free demo is the right place to see whether the base game bores you. It probably will.
Frequently asked questions
What is the RTP of Big Bass Bonanza?
Pragmatic Play lists 96.71%. A 95.67% version also exists and the casino chooses which one to run, so check the game's info screen.
What is the max win on Big Bass Bonanza?

How do you trigger free spins in Big Bass Bonanza?

Is Big Bass Splash better than Big Bass Bonanza?
Yes, on our numbers. Same 96.71% top RTP and same volatility rating, but random modifiers before free spins and fish values up to 5,000x. It scores 7.4 to the original's 6.9.
Is Big Bass Bonanza high volatility?
Bigwinboard rates it 4 out of 5, so high. Our volatility guide explains what that means for how long a budget lasts.
