Big Bass Bonanza is a fishing-themed slot by Pragmatic Play, released in December 2020 on a 5x3 reel layout with 10 fixed paylines. The minimum bet is £0.10, the top prize is 2,100x your stake, and the game is published in more than one RTP version - 96.71% is the figure most widely cited, while some operators run a 94.02% build. This review walks through the paytable, the symbols, the free spins feature and the differences between those versions, using only figures we could verify.
Big Bass Bonanza paytable at a glance

Symbols and what they pay
The symbol set splits into two tiers: card royals as the low end and fishing gear as the premiums, with the money fish and the fisherman wild sitting outside the regular paytable. Wins form when matching symbols land on a payline starting from the leftmost reel, and the premium fishing symbols pay noticeably more than the card values for the same line length.
- Low-pay symbols: the card values 10, J, Q, K and A.
- Premium symbols: themed fishing gear such as the tackle box, dragonfly, fishing rod and float, which top the regular paytable.
- Money fish: special symbols that carry their own cash values rather than line payouts - they matter most during free spins.
- Fisherman wild: substitutes for every regular symbol except the scatter, and doubles as the collector in the bonus round.
- Scatter: the only symbol the wild cannot replace, and the key to the free spins feature.
One honest caveat: the exact per-symbol multiplier values are not published in the sources we could verify, so we do not list them here - operator pages show the live paytable with your stake applied, and the in-game paytable screen is always the authoritative version. What is verifiable is the structure above and every figure in our specification table.
Paylines and how wins form
Big Bass Bonanza uses 10 fixed paylines across its 5x3 grid - you cannot switch lines on or off, so every spin plays all of them. A win needs a run of matching symbols on a line beginning on the first reel, and the payout scales with both the symbol tier and your current stake. Because the line count is fixed, the only lever you control is the bet size.
Free spins and the fisherman wild
The free spins round triggers when 3 or more scatters land on one spin, and it is where the game's real mechanic lives: during the bonus, every fisherman wild on the reels collects the cash values of all money fish in view. Land enough wilds and the feature re-triggers with a growing win multiplier that reaches up to 10x. This collect-and-multiply loop is the reason the series became Pragmatic Play's flagship fishing line - the base game is deliberately simple, and the bonus carries the win potential up to the published 2,100x cap.
Is there a bonus buy in Big Bass Bonanza?
The route into the feature in the original game is the scatter trigger described above. Whether any feature-purchase option appears in your lobby depends on the operator and the market you play in - regulated markets differ on this - so check the in-game menu of the exact build you are playing rather than relying on general descriptions.
RTP versions: which one are you playing?
Two RTP figures for Big Bass Bonanza are published: 96.71% for the standard version and 94.02% for a reduced build that some operators run. This is normal practice for Pragmatic Play titles - the provider ships several return settings and each casino chooses one - but most review pages quote a single number and never mention the difference. The honest way to read it: the game you open at one site may not pay back at the same long-term rate as the same game elsewhere. The in-game information screen shows the RTP of the exact build in front of you, and it is worth the ten seconds it takes to check before you play.
Min bet, max bet and who the stake range suits
The minimum bet is £0.10 per spin everywhere we could verify, which keeps the game accessible for low-stakes play. The maximum is less consistent: some operator pages list £5 as the ceiling while others list 250, reflecting different operator configurations of the same game. If the top of the stake range matters to you, confirm it in the lobby you actually use, because the published figures genuinely differ.
Where to play the official demo
Pragmatic Play hosts the official free demo on its own site, pragmaticplay.com. In Great Britain, free-to-play demos require age verification before you can spin - that is a regulatory requirement, not an operator quirk, and it is why we do not embed the demo on this page.
Playing Big Bass Bonanza on mobile
The game runs in mobile browsers on both portrait and landscape orientation, with the paytable, bet controls and spin button all available on small screens - no separate app is needed. Mobile play uses the same paytable, the same 10 paylines and the same RTP build as the desktop version of the operator you are playing at; nothing about the mathematics changes with the device.
Where it sits in the Big Bass series
The original is the template for an entire family of fishing slots. Bigger Bass Bonanza widens the grid, Big Bass Bonanza Megaways moves the same collect mechanic onto a ways-based engine with a published maximum win of 4,000x stake, and seasonal editions reskin the formula without changing its core. If you learn the fisherman-and-money-fish loop here, you have learned the whole series - the sequels mostly adjust the grid and the win cap rather than the idea.
What we like
- Simple, readable paytable: two symbol tiers plus the money fish, nothing hidden
- Free spins collect mechanic with a re-trigger multiplier up to 10x
- Low £0.10 minimum bet suits careful bankrolls
- Provider publishes its figures, so the key numbers can be verified
What to keep in mind
- Two RTP versions in circulation (96.71% and 94.02%) and the page you play on rarely says which
- Base game is deliberately plain - the entertainment lives almost entirely in the bonus
- Published maximum bet differs between operators, which is confusing when comparing
Our verdict
By the criteria we publish - transparency of the provider's figures, clarity of the mechanics for a newcomer, and how fairly the game communicates its own rules - Big Bass Bonanza holds up well. The specification is published and verifiable, the paytable takes a minute to understand, and the one real trap is external to the game itself: the existence of a reduced RTP build that operators are not eager to flag. Check the version in your lobby, treat the bonus round as the whole point, and the game delivers exactly what it promises.
