Last updated: May 2026. Based on 400+ test spins across the four featured AU-friendly casinos plus the official Pragmatic Play product page. Editor's verdict at the bottom.
Big Bass Bonanza is the pokie that turned a quiet Reel Kingdom studio into the most prolific franchise in modern iGaming. Released in December 2020 through Pragmatic Play's distribution network, this fishing-themed slot didn't just become a hit — it spawned more than a dozen sequels, became the most-cloned-by-other-studios formula of the decade, and still sits in the top-rotated lobby positions at almost every Aussie-friendly casino in 2026. 96.71% RTP, high volatility, a 5×3 grid with 10 fixed paylines, the fisherman wild that collects on-screen money symbols, and a 2,100× max win — those are the headline numbers. The interesting part of this review is what those numbers mean now that the sequels exist.

What is Big Bass Bonanza?
A fishing-themed video pokie built by Reel Kingdom (a Pragmatic Play studio partner) on a clean 5-reel, 3-row grid with 10 fixed paylines. The visuals are deliberately old-school: a deep-blue lake, lily pads on the reel frame, a smiling fisherman waving from the side of the screen, and a folksy banjo soundtrack that drops out into ambient water sounds during free spins. There's no narrative weight here — no spaghetti-western moodboard, no Egyptian mythology, no neon cyberpunk. Just a man with a rod, three sizes of bass, and a tackle box.
That simplicity is the whole point. The math is what made the game famous: a fisherman wild that appears only during free spins and collects every money-value symbol on the reels when he lands. Stack enough money symbols on the screen, drop a fisherman, and the round pays out as a sum of every value he reels in. The collect mechanic was rare in 2020 and is now the standard template for every "fishing slot" — but Reel Kingdom got there first.

How Big Bass Bonanza actually plays
You set a bet from A$0.10 up to A$250, hit spin, and watch the 5×3 grid resolve across 10 paylines. The base game is intentionally low on bells. Three sizes of bass are the high-pay symbols (small, medium, large — the bigger the fish, the bigger the line pay), the fisherman appears occasionally as a base-game wild substituting for everything except the scatter, and the card-rank symbols (10 through A) fill out the low-paying half of the paytable.
What you're actually waiting for is the scatter. Land three or more of the tackle-box scatter symbol anywhere on the reels and you trigger the free spins round, which is where every meaningful payout in this game lives. Three scatters give you 10 spins, four give you 15, and five give you 20. From there, the math changes character entirely.
The base game on Big Bass Bonanza is essentially a delivery mechanism for the bonus. Most sessions you'll see modest line wins, a few near-misses with two scatters, and long dry patches. Don't expect the base game to fund a session — fund the session yourself with bankroll, and play for the bonus trigger.
The free spins round (the only round that matters)
Once you trigger free spins, the fisherman wild changes behaviour completely. In the base game he just substitutes for symbols on a line. In the bonus, every time the fisherman lands he collects every money symbol currently visible on the reels and adds those values to your bonus total.
The money symbols are dollar-value icons (2×, 5×, 10×, 25×, all the way up to a 500× stack) that only appear during free spins. They land randomly on the grid and sit there waiting. When the fisherman shows up, he sweeps the whole screen and pays out the sum.
That's the engine. Stack five money symbols on the reels worth 2×, 10×, 25×, 50× and 100× — a fisherman lands — you collect 187× your bet in one move. Drop another fisherman two spins later when more money symbols have accumulated — collect again. The round builds on itself, and that's where the 2,100× max win ceiling becomes reachable.
There's one more layer. Every fourth fisherman wild that appears during the bonus triggers 10 retriggerable respins. So if you land four fishermen during your 10 free spins, you get an additional 10-spin sub-round with the same collect mechanic. Land four more fishermen in the sub-round, you get another 10 spins. The retrigger is the bridge to the max-win.
Why this game launched a franchise
When Reel Kingdom released Big Bass Bonanza in December 2020, the slot market was dominated by Pragmatic Play's own Gates of Olympus, Sweet Bonanza, and Wolf Gold. Fishing-themed games existed but were niche — mostly Asian-market regional titles. Reel Kingdom built a fishing slot for the Western market with a clear, satisfying loop: bonus triggers easily enough to feel achievable, the fisherman collect mechanic is visually rewarding every single time it happens, and the bet range scales from casual (A$0.10) to high-roller (A$250) without the math falling apart at either end.
It worked. Within a year the studio had released Bigger Bass Bonanza (the first sequel — same template, sharper volatility), then Bigger Bass Splash, Big Bass Splash, Big Bass Hold and Spinner, Big Bass Mission Fishin', Big Bass Christmas Bash, Big Bass Halloween, Big Bass Day at the Races, Big Bass Floats My Boat, Big Bass Crash, and eventually Big Bass Bonanza 1000 — a sequel with a max-win ten times the original. The franchise has more entries now than Hacksaw Gaming's entire catalogue.
That history matters for one reason: the original Big Bass Bonanza is now the smallest game in its own family. The 2,100× max is the lowest ceiling of any title in the franchise. The sequels push 5,000× (Bigger Bass), 10,000× (Big Bass Splash), and 20,000× (Big Bass Bonanza 1000). The original is still played because the simplicity is part of the charm — but if you're chasing max-win clips, the original isn't where they happen anymore.
The 2,100× max win is modest — and that's fine
Let's be honest about this. In 2020, 2,100× was a competitive slot ceiling. In 2026, it's modest. The market has moved on to multipliers in the 10,000× to 50,000× range for any high-volatility slot worth a streamer's attention.
What does 2,100× actually mean? From a A$1 bet, that's A$2,100. From a A$10 bet, that's A$21,000. From the A$250 max bet, that's A$525,000 — still a life-changing hit, but the practical reality is that most Big Bass Bonanza bonuses pay between 5× and 80× stake. The max is the ceiling of the dataset, not the average — see our max win breakdown for the realistic distribution.
If you want bigger numbers, play the sequels. If you want the original Reel Kingdom feel — the cleanest version of the formula, before the studio added bonus buys, scatter multipliers, and 1,000× money symbols — the original is still the right game. It's the difference between drinking a single-malt Scotch and a fancy cocktail: both work, depends what you're in the mood for.
Why Aussies love it
Big Bass Bonanza lands directly in the comfort zone of Australian pokie players raised on land-based five-reel games. The grid is familiar (5×3 was the pub-pokie standard), the paylines are fixed at 10 (no over-thinking which lines to activate), the bet range starts at A$0.10 (a single coin in old-money terms), and the bonus round delivers visible, satisfying wins — the fisherman literally reels fish out of the water on every collect. There's no abstract mechanic to learn. You can watch a friend play for 60 seconds and understand the entire game.
Australian player data from the Pragmatic Play distribution network places Big Bass Bonanza in the top-10 most-spun slots across AU-targeting offshore brands for every quarter since launch. That's a five-year streak. Few slots from 2020 still rotate at that frequency in 2026.

Quick FAQ
Is Big Bass Bonanza legit? Yes — built by Reel Kingdom under the Pragmatic Play distribution network with RNG certified by GLI and iTechLabs. Pragmatic Play is one of the most-licensed slot providers globally with active certifications in Malta, the UK, Romania, Sweden, and many other regulated markets.
What's the max win? 2,100× your bet. From a A$10 spin that's A$21,000. Reached through stacking money symbols in the free spins round and triggering the every-4th-fisherman respin chain.
Does the original have Bonus Buy? No. The original Big Bass Bonanza launched before Pragmatic Play added the Bonus Buy feature to its slot lineup. Several sequels (Bigger Bass Bonanza, Big Bass Splash, Big Bass Bonanza 1000) include Bonus Buy at roughly 100× stake. The original requires natural triggers.
Can Aussies legally play it? Yes, at licensed offshore casinos. Australian operators don't offer real-money online slots under the Interactive Gambling Act, so AU pokie players use offshore-licensed sites (the four featured brands hold Curaçao licences).
Is the 2,100× max realistic? It's the theoretical ceiling. In practice, most bonus rounds pay between 5× and 80× stake. The max requires fisherman wilds, retrigger chains, and 500×-value money symbols to all align — possible but rare.
Does it have a jackpot? No fixed or progressive jackpot. The 2,100× ceiling is achieved through the fisherman-collect mechanic, not a separate prize pool.
How does it compare to the sequels? The original has the cleanest version of the formula and the lowest max ceiling. Sequels add bonus buys, higher max wins, and extra modifiers. See our Big Bass Bonanza vs Sequels breakdown.
