Big Bass Bonanza 1000: honest review, 96.51% RTP and a 20000× ceiling

Big Bass Bonanza 1000 is the 2025 entry in Pragmatic Play’s most prolific fishing series — and the only one of the “1000” builds that isn’t a scatter pays slot. Everything here stays old-school: a 5×3 grid, 10 fixed lines, bets from €0.10, and the same fisherman wild everyone recognises. What separates it from the original Big Bass Bonanza is scale: the max win jumps from 2100× to 20000× your bet.

Is Big Bass Bonanza 1000 worth playing?

Yes, but it’s worth understanding the trade — and this time the trade isn’t free.

It’s for you if you like the series and want a ceiling the original never had. The 2100× cap on the 2020 game was always its most obvious limit: a fun slot with a modest top end. This version fixes that. On top of that, the fixed-line structure is still among the most legible in the market — you can see exactly why you won, which isn’t true of scatter pays grids.

It’s not for you if what you liked about the original was its balance. There’s a concrete, measurable cost here: the default RTP drops from 96.71% to 96.51%. Not dramatic, but a real reduction, and it comes bundled with a lot more variance. If you played Big Bass for the feeling of a session that lasts, the original is still the better pick in the series.

10 fixed lines, no surprises

No clusters, no pay-anywhere. Symbols have to line up left to right on one of the 10 fixed lines. That makes the base game easier to read, even though — as in most modern high-volatility slots — base payouts alone won’t sustain a session.

The fisherman wild and the money fish

The series’ signature mechanic, and the reason it exists. During free spins, fish symbols carry a cash value, and the fisherman wild collects the value of every fish on screen when he appears. Without a fisherman, the fish pay nothing. That dependency is what concentrates almost all of the game’s potential inside the bonus.

The climbing bonus multiplier

As more fishermen appear over the course of the round, the multiplier applied to collected fish values rises, and retriggers extend the round. The result is the series’ familiar shape: most bonus rounds end with a modest return, and the minority that survive long enough to pair a high multiplier with high-value fish are the ones that produce headline numbers. In the 1000 build that tail is far longer — hence the jump from 2100× to 20000×.

Symbols and payouts

We’re not publishing a per-symbol paytable, because this build’s values aren’t the original’s and we haven’t confirmed them with the provider. The in-game info panel always carries the exact figures for the version your casino runs. The structure looks like this:

Element	How it works
Grid	5×3 with 10 fixed lines
Wins	Symbols lined up left to right on active lines
Money fish	Symbols carrying a cash value that only pays when a fisherman wild collects it
Fisherman wild	Appears during free spins and collects every fish visible on screen
Bonus multiplier	Climbs as more fishermen appear during the round
Retriggers	Extend the free spins and keep the multiplier you’ve already earned
Max win	20000× your bet

Note: 96.51% is the default RTP published by Pragmatic Play itself — in this case the spec comes from the provider’s own game page rather than an aggregator, which is the best source available. It’s worth looking at that number carefully: it’s lower than the original Big Bass Bonanza’s 96.71%. Unlike Gates of Olympus 1000 and Sweet Bonanza 1000, this bigger ceiling cost a little RTP as well as variance. And as always, a published figure is a reference point: some operators run lower configurations, so check the number in the in-game info panel before you stake.

Big Bass Bonanza 1000 vs the competition

Slot	Default RTP	Volatility	Max win	System
Big Bass Bonanza 1000	96.51%	High	20000×	5×3, 10 fixed lines, fisherman wild
Big Bass Bonanza	96.71%	Medium-high	2100×	Same base, better RTP, far lower ceiling
The Dog House	96.51%	High	6750×	5×3, 20 fixed lines, multiplier wilds
Sweet Bonanza 1000	96.53%	High	25000×	6×5 scatter pays, bombs to 1000×
Gates of Olympus 1000	96.5%	High	15000×	6×5 scatter pays, orbs to 1000×
Sugar Rush 1000	96.00%	High	25000×	7×7 clusters, spot multipliers

Within the series the choice is honest and simple: the original has the better default RTP and the more balanced game, while the 1000 build has nearly ten times the ceiling and charges for it in variance plus two tenths of RTP. Against the other 1000 builds, Big Bass stands out as the only one with a payline structure — if scatter pays grids wear you out, this is where you find an alternative without giving up a high ceiling. If you want the same format but less extreme, The Dog House runs at the same default RTP with a much more contained top end.

Bankroll tips

This slot’s base game won’t carry you: almost everything depends on reaching the free spins and on them lasting. In practice, the number of spins you can afford matters more than the size of each one. Pick a stake that gives you room for several hundred spins, set a loss limit before you open the game, and don’t revise it mid-session. Be especially careful with the bonus buy where it’s offered: it concentrates risk into a single play and does nothing for the default RTP. Try the demo first — it shows you, at no cost, how long the gaps between bonuses usually are.
