Game Overview
Big Boat Big Catch drops you into a sunny underwater scene with gulls overhead, bubbles everywhere, and a grid that’s wider than the usual 5×3. It’s a 5×4 video slot with 10 fixed paylines, built around Prize Fish that show cash values and a bonus round where the fisherman starts hoovering them up. BGaming lists RTP at 97.2% and calls volatility very high, so don’t expect a calm cruise — this one can go quiet, then spike when the bonus connects. Free Spins trigger with 3+ Bonus symbols, or you can use the optional Buy Bonus / Chance x2 features. Keep reading and you’ll know exactly what each symbol does, how Prize Fish pay in base play versus the bonus, and where the win ceiling sits (up to 5,000x).
Game Features & Mechanics
-
10 Paylines
Wins are paid left to right on 10 fixed paylines. Standard symbols require a normal line hit to pay, while Prize Fish are an exception and pay based on their combined values.
-
Free Spins
Landing the required symbols in a single spin triggers 10, 15, or 20 Free Spins. Any line wins are paid first, then the Free Spins bonus begins.
-
Prize Collection
During Free Spins, Prize Fish appear on reels 2–5 and do not pay on their own. You must land the Fisherman Wild to collect and pay out their values.
-
Boost Options
The Buy Bonus feature instantly launches Free Spins on the next spin for the displayed price. The Chance x2 option slightly increases your stake to improve the odds of triggering the bonus, but it disables the Buy Bonus button.
Technical Specifications
-
Volatility Level
BGaming rates Big Boat Big Catch as very high volatility. That usually means longer dry spells, with the session’s best moments tied to Free Spins and collected Prize Fish.
-
RTP Explained
The theoretical RTP is 97.2% in the base game. BGaming also lists separate RTP figures for the Buy Bonus and Chance x2 modes, depending on how you access Free Spins.
-
Bet Range
Bet limits vary by casino and currency, but listings commonly show a AU$0.10 minimum up to about AU$50 per spin. Buy Bonus cost and Chance x2 scale with your stake.
Paytable & Symbol Values
Most of the base game is classic line-play with bright, simple icons. The lower-value set is made up of colourful clam shells (blue, green, purple, orange, and red), which stack up often and keep the board busy. Stepping up, you’ll see fishing gear: a shiny hooked lure, a red fishing reel, and a purple tackle box packed with bait. These “regular” symbols win in the usual way — matching on an active payline from left to right, so they’re your steady drip while you wait for the special fish and the bonus. The big twist is that the Prize Fish aren’t part of this normal paytable logic; they pay by their displayed values, which we cover in the special symbol section below.
Special Symbols
Bonus symbol
The Bonus icon can land on any reel in the main game. Hit 3+ in a single spin to launch Free Spins (10/15/20 spins for 3/4/5 symbols).
Wild Symbol
The Fisherman Wild appears only during Free Spins and substitutes for all standard symbols. More importantly, it collects and pays out the total value of all Prize Fish currently visible on the reels.
Prize (Fish) Symbols
Prize Fish display random cash values. In the base game, they pay when 3 or more appear on a winning payline. During Free Spins, Prize Fish land on reels 2–5 and do not pay on their own — their values are only awarded when collected by the Fisherman Wild.
Graphics, Animations & Sound Design
-
Graphics
This one’s cheerful and clean. The 5×4 grid sits in bright blue water, with simple, chunky icons that stay readable even on a phone. You’ve got colourful clams, tidy fishing gear, and those fish-with-values that pop immediately when they land.
-
Animations
Spins are snappy, with bubbles and small splash hits rather than screen-filling fireworks. The key animation is the bonus collection: when the Fisherman Wild appears, it “grabs” the Prize Fish values on the reels so you can see exactly what got paid.
-
Sound Design
Audio matches the sunny vibe: light sea ambience, soft win jingles, and a louder cue when a Wild collects fish in Free Spins. It’s upbeat without being noisy, which helps during longer sessions where you’re waiting for the bonus to connect.
-
Visual Feel & Interactivity
Buttons are big, spacing is tidy, and everything important stays in the lower bar. Quick spin and autoplay are available, but BGaming notes that some features can be restricted by local licence rules. Either way, the layout makes it easy to track Bonus symbols and fish values.
Game Gallery
Big Boat Big Catch on Mobile Devices and Other Platforms
Big Boat Big Catch is built in HTML5, so it’s designed to run straight in a browser across phones, tablets, and desktop. The grid is 5×4, which gives you a bit more to watch than a classic 5×3, especially when Prize Fish values start landing alongside regular line symbols. On smaller screens, landscape mode keeps the reels from feeling cramped and makes it easier to spot when a Bonus symbol drops in. We also like that the key options are right there: Buy Bonus and Chance x2 sit on the left, and the info menu is always one tap away. Just remember that autoplay, quick spin, and purchase features can be limited by local licence rules, so what you see may vary by casino.
-
Android
Android play is smooth in-browser, and the symbols stay crisp at full width. Use landscape, and keep an eye on the left panel if you’re using Chance x2.
-
iOS
On iPhone, it runs well in Safari or any casino wrapper that launches the web client. Landscape gives you cleaner spacing for the 5×4 grid.
-
Tablet
Tablet is the comfy option: more reel space, bigger fish values, and fewer mis-taps. It’s ideal if you want to follow the Wild collection without squinting.
-
Desktop
Desktop is best for clarity and rule-checking. You can keep the reels large, open the pay info quickly, and still track when every 4th Wild upgrades the stage.
Optimal Gameplay Tips
-
Use Stable Connection
EssentialIf you’re on mobile data, avoid signal drops during Free Spins. Collections and stage upgrades resolve automatically, but a stable connection keeps the session feeling seamless.
-
Landscape Mode Recommended
RecommendedLandscape mode makes the 5×4 layout breathe. You’ll read fish values faster and spot Bonus symbols without the interface nibbling away at reel space.
-
Audio Settings
OptionalKeep sound effects on low if you can. The collection cue helps you notice when a Wild has scooped fish values, even if you’re not staring at the screen.
-
Full Screen Mode
RecommendedFull screen on desktop is handy for long runs. It removes browser clutter and keeps paylines and symbol highlights easy to follow when wins stack together.

Our Final Verdict
Why It’s Worth Playing
- 97.2% RTP is genuinely strong, giving you friendlier long-run maths than most recent pokies
- The Free Spins ladder is easy to follow: every 4th Wild adds 10 spins and boosts multipliers
- Prize Fish can pay in the base game, so you’ll still see value hits outside the bonus
- Very high volatility plus a 5,000x cap keeps the upside exciting for swing-hunters
- Buy Bonus and Chance x2 options let you reach the bonus faster, where permitted
Things to Consider
- Very high volatility means dry spells are normal, so bankroll management matters more than usual
- In Free Spins, Prize Fish only pay when a Wild lands, so some spins can feel like dead air
- Purchase and autoplay features can be restricted by local licence rules, depending on the casino
Overall Rating
8.9
Bottom Line
Big Boat Big Catch is a bright, no-fuss fishing slot with a clear money path: land Prize Fish, then let the Fisherman Wild collect them in Free Spins. On paper, the 97.2% RTP is a standout, and the very high volatility matches the idea that the best returns come in bursts rather than drips. The bonus is the main event, especially once you start hitting that ‘every 4th Wild’ ladder that adds spins and upgrades multipliers from x2 to x3 to x10. If you like simple rules, big swings, and a 5,000x ceiling, this one’s worth a cast.
