What we like / What could be better
What we like
- 12,000x ceiling gives real upside off a A$0.20 spin
- Bonus Buy skips the grind for players who want the free-spin round on demand
- Two RTP configurations exist, so a better room is out there if you can confirm which lobby runs it
- Collector and multiplier stacking add variance beyond a flat multiplier slot
What could be better
- High volatility means long dry stretches between meaningful hits
- We haven't verified which offshore lobby currently lists this title live
- The bonus buy price isn't published anywhere we could check; you only see it in-app
- No confirmed sibling title in NetGame's lineup to compare this one against
What Big Catch Bonanza: Bonus Buy Is
NetGame built this pokie around a fishing theme: hooks, nets and a 5x4 reel grid running across 12 fixed paylines. It launched in December 2023, sits in the high-volatility bracket and pays out on a 12,000x total-bet ceiling. Stakes run from A$0.20 to A$40.00 per spin, wide enough to size a session by bankroll rather than by the number printed on the paytable.
The core loop is standard for the genre: land matching symbols, collect the fishing icon in free spins, watch multipliers stack. What sets this review apart from a spec sheet is what those numbers mean once you put real money behind a spin, which is the rest of this page.
RTP: 96.05% or 96.23%, and Which One You're Actually Playing
NetGame ships Big Catch Bonanza: Bonus Buy with two RTP settings: 96.05% and 96.23%. The operator picks which one goes live, not the player, and the 0.18-percentage-point gap between them compounds over thousands of spins.
Check the info panel inside the game before you commit a bankroll. Most NetGame titles show the active RTP on the rules screen, next to the paytable. If the number there doesn't match either 96.05% or 96.23%, you're likely looking at a build the operator has customised for that lobby, which happens more often on bonus-buy titles than on standard slots.
We haven't verified which configuration any specific offshore lobby runs on this title. Treat the figure in the game's own info screen as the one that counts, not the number on a casino's promotional page.
The 12,000x Ceiling: What It Pays at Different Stakes
A 12,000x multiplier means nothing until you attach a stake to it. Here's what the ceiling converts to across the game's own bet range:
| Stake per spin | Ceiling win (12,000x) |
|---|---|
| A$0.20 (minimum) | A$2,400 |
| A$1.00 | A$12,000 |
| A$5.00 | A$60,000 |
| A$20.00 | A$240,000 |
| A$40.00 (maximum) | A$480,000 |
High volatility and a five-figure multiplier don't show up often. The ceiling is a free-spin outcome, not a base-game one: it needs the Collector mechanic to fill and the multiplier symbols to stack inside the same bonus round. Most sessions won't get near it. Pick your stake by how many spins your bankroll can survive, not by how big a number you want to see on screen.
Buying the Bonus: What the Button Actually Costs
The bonus buy button is live wherever this pokie is stocked in offshore lobbies. Pressing it skips the base game and drops you straight into the free-spin round with the Collector mechanic and multiplier symbols already active.
The price isn't fixed in the spec we pulled for this title. NetGame quotes it live inside the game client as a multiple of your total stake, and that quote can shift with the bet you've dialed in before you press the button. Read the on-screen number every time, not the figure you remember from your last session.
Buying the round doesn't buy a result. It buys entry to the free-spin feature at a fixed cost instead of an unknown number of base-game spins; the outcome once you're inside is exactly as random as if you'd triggered it naturally.
Free Spins, the Collector Mechanic and Multiplier Symbols
Three mechanics carry the bonus round. Free Spins give you a fixed batch of extra turns once triggered. The Collector mechanic gathers a designated symbol across those spins, building toward an upgrade inside the same round. Multiplier symbols stack on top of whatever the Collector has gathered, and Retriggering can extend the round if the trigger symbols land again before the spins run out.
None of this is unique to Big Catch Bonanza. What matters for your bankroll is that all three mechanics need to line up in the same round to reach the higher multipliers, which is exactly why the 12,000x ceiling is rare rather than typical.
High Volatility in Practice: The Rhythm of the Reels
High volatility means fewer, bigger hits and longer stretches of nothing in between. Combined with a 12-line, 5x4 grid, this pokie leans toward variance over frequency. Don't expect the reels to feed you small wins to top up the balance between bonus rounds.
That rhythm changes how a demo session should be read. Ten minutes in free play won't show you the shape of the game; high-volatility titles need enough spins to hit a bonus round before the numbers mean anything. Treat a short demo as a look at the graphics and controls, not a preview of the return.
How This Pokie Sits Against the Rest of the Fishing Shelf
Fishing-themed pokies with a bonus buy option aren't rare; Pragmatic Play's Big Bass Bonanza set the template the category still follows. Big Catch Bonanza: Bonus Buy runs a tighter 12-line, 5x4 grid rather than the wider grids some competitors use, and its 12,000x ceiling sits mid-pack for the genre: high enough to matter, not the highest number on the shelf.
NetGame hasn't published a numbered sequel or a confirmed sibling title for this game in the spec we're working from, so there's no direct in-house comparison to make yet. If that changes, this section is where we'll add it.
How to Play: Size Your Bet to Your Spins, Not Your Target Win
The maths above only helps if the bet you choose matches the bankroll behind it. Three steps before you touch the buy button:
- Decide how many spins you want your session to last, not how much you want to win.
- Divide your bankroll by that spin count to get a stake per spin. A$100 over 200 spins is A$0.50 a spin, comfortably inside the A$0.20 to A$40.00 range.
- Run the demo first. High volatility means a short free-play session tells you little, but it's still the only way to see the Collector mechanic and the free-spin round without spending anything.
None of this changes what a spin pays. The outcome doesn't depend on bet timing, session length or anything you do beyond choosing the stake and pressing spin. What you control is how long your bankroll survives long enough to see a bonus round land.

We haven't run a landing-page availability check on this specific title yet, and none of our three withdrawal-speed measurements to date came from a payout triggered by this game, so we can't quote a cash-out time for it.
Where to Play Big Catch Bonanza: Bonus Buy
Australia's Interactive Gambling Act keeps locally licensed operators out of online casino games, so this pokie only turns up in offshore lobbies. We haven't completed a landing-page check confirming which lobby currently stocks it live, and studio catalogues change without notice.
Read the game info panel for the RTP figure before you play for real money. It's the fastest way to confirm you're looking at the configuration this review describes, rather than a different build of the same title.
