Our verdict
Big Bass Bonanza keeps things refreshingly simple next to the 6-reel tumblers: a classic 5×3 grid with ten paylines and a single, very moreish bonus. The fisherman is the key — during free spins he is a wild who collects the cash value of every money symbol on screen.
Collect enough fish scatters in the bonus and you retrigger more spins while the fisherman's multiplier climbs to 2x, 3x and eventually 10x, applied to everything he reels in. It is a high-volatility game with a friendlier 2,100x cap, which makes it feel more sustainable than its huge-ceiling cousins.
High-ceiling games reward patience, not chasing.

Hands-on
The interface in Big Bass Bonanza not on GamStop is identical to the UK-licensed build — Pragmatic Play keeps the control layout the same across its catalogue, so if you have spun any of its slots before you will feel at home in seconds. The plus and minus buttons beside the spin wheel change your bet and open the bet menu, the large central button starts the reels, and the lightning icon cycles spin speed through normal, quick and turbo. Holding the spacebar fires turbo spins on desktop, and SPACE or ENTER will start and stop the reels at any time.
Around the edges you get the hamburger icon for the settings menu, a speaker toggle for sound and music, and the "i" information button that opens the six-page rules and paytable screens we walk through below. The CREDIT and BET labels along the bottom show your current balance and total stake — clicking either label switches the display between a coins view and a cash view, which is worth knowing because the paytable is expressed in coins.
Paytable
All symbols pay left to right on adjacent reels starting from the leftmost reel, across the game's ten fixed paylines. The values below are taken directly from the in-game paytable at a £1.00 total bet — they scale in a straight line with your stake, so at £2.00 every figure doubles. The red-and-white float is the premium symbol, and unusually for a five-reel slot it pays from just two of a kind.
| Float (premium) | 2 = £0.50 · 3 = £5.00 · 4 = £20.00 · 5 = £200.00 |
|---|---|
| Fishing rod | 3 = £3.00 · 4 = £15.00 · 5 = £100.00 |
| Dragonfly | 3 = £2.00 · 4 = £10.00 · 5 = £50.00 |
| Tackle box | 3 = £2.00 · 4 = £10.00 · 5 = £50.00 |
| Bass (fish group) | 3 = £1.00 · 4 = £5.00 · 5 = £20.00 |
| A, K, Q, J, 10 | 3 = £0.50 · 4 = £2.50 · 5 = £10.00 each |
| Fisherman (wild) | Appears on all reels during free spins, substitutes for everything except the scatter — and collects money values |
| Bass scatter | Appears on all reels; 3+ triggers free spins |
The royals deliberately pay small — this is a feature-driven game, and the base-game maths is tuned so the real money sits in the free spins. Use the calculator below to see exactly what any line win is worth at your stake.
Pick a symbol, how many land on a payline, and your bet — and see exactly what that catch pays. Values use the official paytable and scale linearly with stake (min £0.10, max £250).
Quick reference — free spins triggers: 3 scatters = 10 spins · 4 scatters = 15 spins · 5 scatters = 20 spins. Only the highest win is paid per line; wins on multiple lines are added together. This calculator is for understanding the paytable, not predicting results — every spin is random and high-volatility games pay less often on average.
The main event
Everything in Big Bass Bonanza funnels toward one feature, and it is worth understanding properly before you chase it. Landing three, four or five bass scatters awards 10, 15 or 20 free spins respectively. During the round, every fish on the reels doubles as a money symbol carrying a random cash value — possible values run 2x, 5x, 10x, 15x, 20x, 25x, 50x and a headline 2,000x total bet.
The fisherman is the collector. He appears as a wild on all reels during free spins, and whenever he lands he scoops the value of every money symbol on screen. Crucially, the wilds you collect stay counted for the whole round: every fourth fisherman retriggers the feature with 10 more spins and raises the collection multiplier — 2x after the first retrigger, 3x after the second, and a punchy 10x after the third, applied to everything he reels in from that point. After the third retrigger the feature cannot retrigger again, so the dream scenario is reaching that 10x stage with spins still in hand.
Two smaller rules matter more than they look. When only one wild is on screen at the end of a free spin, the game can randomly throw extra fish money symbols onto the reels — a quiet boost that keeps lone-wild spins alive. And the round is hard-capped: if total winnings reach 2,100x your bet, the feature ends immediately, the win is paid and any remaining spins are forfeited. That cap is the game's true maximum win.
The maths
Big Bass Bonanza carries Pragmatic Play's high volatility rating (4/5 lightning bolts) — in the game's own words, it pays out less often on average but the chance of hitting big wins in a short span is higher. Sessions tend to be streaky: stretches of small royal wins, then a feature that decides the whole sitting. Budget for the dry spells.
The theoretical RTP is 96.71% in the default build — slightly above the industry's ~96% average — but operators can license reduced versions at 95.66% or 94.73%, so before you spin Big Bass Bonanza not on GamStop it is always worth opening the in-game rules at the casino you actually play to confirm which RTP build is running. Bets run from £0.10 to £250 per spin across the ten fixed paylines (you cannot reduce the line count), wins pay left to right, and only the highest win per line counts, with multi-line hits added together.
Pace control
The AUTOPLAY button opens a menu where you simply tap the number of automatic spins you want and the game takes over; pressing the button again stops it at any time. A SKIP SCREENS option auto-dismisses the feature introduction and end screens after a short pause, which keeps long sessions moving. Combine autoplay with turbo speed — or just hold the spacebar — and spins resolve about as fast as the game allows.
A word of honest caution: speed tools exist to remove friction, and friction is not always your enemy. Faster spins mean more stake through the game per hour, which on a high-volatility slot steepens the swings. If you use autoplay, decide a spin count and a stop point before you start rather than re-upping on autopilot.
Under the hood
The hamburger icon opens a settings menu covering the practical toggles: the intro screen, ambient music and sound effects can each be switched independently, and a GAME HISTORY link opens a full record of your recent spins and results — genuinely useful if you want to audit a session afterwards. Inside the information screens, the green arrows page through the six rules screens and the X closes them; the bet menu shows lines, coins per line and coin value so you can fine-tune the exact stake rather than stepping through presets.
The newer system settings panel adds a mobile-focused extra: a battery saver mode that reduces animation speed to stretch battery life — worth flipping on for longer phone sessions. Total bet can be adjusted with simple plus/minus controls from the same panel. The game runs identically in mobile browsers, scaling to portrait or landscape with the same six rules pages and the 2,100x cap noted in both menus.
FAQ
Yes — Big Bass Bonanza is available at casinos licensed outside the UK that are not part of the GamStop network, so a GamStop self-exclusion will not block access. However, if you self-excluded because of gambling harm, we strongly recommend you keep that exclusion and seek support from GamCare rather than seeking out non-UK sites.
The default RTP of Big Bass Bonanza is 96.71% (some operators run 95.66% / 94.73%). It is always worth checking the game's information panel before you play, as some operators run lower-RTP builds of the same game.
Yes. Big Bass Bonanza is a high-volatility slot, so wins are less frequent but can be much larger. It suits players comfortable with longer dry spells in pursuit of the bonus features.
During the free-spins round, money symbols carry cash values and the fisherman acts as a wild. Whenever the fisherman appears, he collects the value of every money symbol currently on the reels. Collecting enough fish both retriggers spins and increases his multiplier, up to a maximum of 10x.
Three scatters award 10 free spins, four scatters award 15 and five scatters award 20. Every fourth fisherman wild collected during the round retriggers the feature with 10 more spins and raises the money-collection multiplier to 2x, then 3x, then 10x. After the third retrigger the feature cannot retrigger again.
The maximum win is capped at 2,100x your total bet. If a free spins round reaches 2,100x, the round ends immediately, the win is awarded and any remaining free spins are forfeited.
Bets run from £0.10 up to £250 per spin across ten fixed paylines. All paytable values scale linearly with your stake, and you can fine-tune coins per line and coin value from the bet menu.
Yes. The autoplay menu lets you choose a set number of automatic spins and includes a skip-screens option, while the spin-speed button cycles normal, quick and turbo modes. Holding the spacebar also triggers turbo spins on desktop.
Once you've weighed up Big Bass Bonanza not on GamStop, it's worth comparing it against the rest of the series and the wider catalogue before deciding where to play.
