Last updated: May 2026. Bonus Buy availability and pricing verified across the four featured AU casinos in April-May 2026.
If you don't want to wait for the natural trigger, Evoplay publishes a separate Bonus Buy edition of The Greatest Catch for markets where Bonus Buy is permitted. The buy lets you pay a multiple of your current stake to enter the free-spin round directly, skipping the base-game grind. This article covers what the buy costs, the math of buying vs spinning for natural triggers, where to find the Bonus Buy edition for AU players, and whether it's actually worth it for your bankroll.

Why Bonus Buy exists
The natural free-spin trigger on The Greatest Catch lands roughly once every 130-180 base-game spins. For a session of 30 minutes at A$1 per spin, that means you're statistically likely to see at most one or two triggers — and possibly none if the variance runs against you.
Bonus Buy is a shortcut: pay an upfront cost to be placed straight into the free-spin round. It exists because some players (streamers especially) want to spend session time inside the high-payout part of the game rather than spinning the base. It is not a guaranteed win — the round still produces a random outcome — but it removes the waiting.
The buy structure for The Greatest Catch
The Bonus Buy edition of The Greatest Catch offers a direct purchase of the free-spin round at an upfront cost. Pricing is typically:
| What you buy | Approximate cost (× current stake) |
|---|---|
| Free-spin round (10-spin entry) | ~80× - 100× the stake |
Exact pricing varies by casino deployment of the Bonus Buy edition. Expect the buy cost to sit in the 80×-100× range of your current stake. At A$1 per spin, the buy costs approximately A$80-A$100. At A$2 per spin, A$160-A$200.
The bought round behaves identically to a naturally triggered round — same paytable, same retrigger mechanics, same wild substitutions, same possible upper-tier outcomes.
Is Bonus Buy a separate game?
Yes — Evoplay ships the Bonus Buy edition as a separate SKU in casino lobbies, distinct from the base The Greatest Catch. Casinos that offer it list it alongside the standard game. Some casinos carry only the base edition; some carry both; some carry neither (depending on whether their licence permits Bonus Buy features).
Look in the lobby for both:
- The Greatest Catch (base edition — natural triggers only).
- The Greatest Catch Bonus Buy (or "Feature Buy" — buy-in edition).
If only the base edition is available at your casino, the buy is not accessible. Switch casinos if the buy is a must-have.
Bonus Buy vs natural trigger — the math
The fundamental question: is buying worth it?
Natural-trigger expected value. Over a long sample of base-game spins, every dollar wagered returns approximately 96.09 cents (the long-run RTP). Roughly half that return is concentrated in free-spin rounds. So across 150 spins at A$1 each (A$150 wagered), you'd expect:
- Approximately A$144 returned overall (96.09% of A$150).
- Of that, approximately A$70-85 comes from free-spin rounds.
- The remaining A$60-75 comes from base-game wins.
- Net expected loss: A$6 (the 3.91% house edge applied to A$150 wagered).
Bonus Buy expected value. A 100× buy at A$1 stake costs A$100 and delivers one free-spin round. Evoplay's Bonus Buy editions are typically tuned so the round's expected return aligns with the cost minus the house margin — so an expected return around 96-97% of the buy cost.
For A$100 spent on a buy:
- Expected return: ~A$96 (similar to the certified game RTP).
- Net expected loss: ~A$4 per buy.
Comparison. The expected loss per dollar wagered is roughly equivalent between natural play and Bonus Buy. The difference is variance density — Bonus Buy concentrates all the variance into one event, while natural play spreads it across many spins.
When Bonus Buy makes sense
You should consider Bonus Buy if:
- You have limited session time and want to focus on the bonus round rather than the base grind.
- You're a streamer or content creator looking for high-payout-density content.
- You want to test the bonus round before committing to a long base-game session.
- You enjoy the all-or-nothing structure of a single high-stakes round more than the rhythm of base play.
When Bonus Buy is a bad idea
You should avoid Bonus Buy if:
- Your bankroll is tight. A A$100 buy on a A$200 bankroll is half your session evaporated in one round if the outcome is poor.
- You're chasing losses. Buys are emotionally addictive after a base-game cold streak; the math doesn't favour the chase.
- You're claiming a welcome bonus. Most welcome bonuses exclude Bonus Buy from wagering contribution — buying with bonus funds may breach the offer's terms and void the bonus entirely.
- You enjoy the slow drip of base play. Skipping the base game with a buy removes most of what makes a slot session feel like a session.
Wagering and welcome-bonus interaction
Critical warning for bonus-fund players: at almost every casino, Bonus Buy is excluded from welcome-bonus wagering. If you have an active welcome bonus and you press the buy button:
- The buy may be blocked entirely.
- The buy may proceed but the casino may void your welcome bonus for using a restricted feature.
- The buy may proceed and the casino may simply not count the buy toward wagering requirements.
Read your casino's bonus terms before considering a buy with active bonus funds. The safe path: clear your welcome bonus first, then play Bonus Buy with regular deposit funds.
Where AU players can find the Bonus Buy edition
Bonus Buy availability across the four featured casinos:
| Casino | Bonus Buy edition available |
|---|---|
| Vegasnova | Yes (lobby search "Bonus Buy") |
| Joe Fortune | Yes |
| GreatSlots | Yes (filter by "Buy Bonus" tag) |
| CasinoRocket | Yes |
All four host both the base and Bonus Buy editions at time of last verification (May 2026). Some smaller AU-facing brands carry only the base edition; if Bonus Buy is missing from a casino's lobby, the brand likely operates under a jurisdiction that restricts buy features.
How to use Bonus Buy responsibly
If you decide to buy, treat it as a discrete entertainment decision rather than a strategy:
- Budget the buy as part of your session bankroll, not on top of it. A A$200 session that includes one A$100 buy is a session, not a session plus a separate event.
- Don't chain buys after a bad outcome. If a A$100 buy returns A$15, the math doesn't favour buying again immediately. Each buy is independent of the last.
- Cap your buy frequency. Maximum one buy per session as a hard rule for most players.
- Stop on a meaningful win. A 100×+ buy outcome should end the session with a withdrawal.

Quick FAQ
Is Bonus Buy a different game or the same game? The Bonus Buy is a separate SKU shipped by Evoplay alongside the base edition. Same theme, same math model, same paytable; just adds the buy feature.
Does the buy round have a different RTP? Bonus Buy rounds are typically tuned to the same overall RTP as the base game (~96%). Per-buy expected value is roughly equivalent to per-spin expected value, scaled by the buy cost.
Can I buy a four-scatter or five-scatter trigger directly? No — the buy gives you the standard 10-spin round entry. The four- and five-scatter tiers can only be reached through natural-trigger play, which is also the only realistic path to the 10,000× ceiling.
Is Bonus Buy banned in any markets? Yes — the UK has banned slot Bonus Buy features for licensed operators since 2024. Australia's offshore Curaçao framework permits it. Other jurisdictions vary.
Why is Bonus Buy so expensive? The cost reflects the average value of the round. Casinos and providers don't sell something for less than its expected payout — the buy cost includes the house margin.
Can I cancel a buy after clicking it? No — once the buy is confirmed, the round runs to completion.
Is the buy random or fixed? Random — the buy puts you into a round, but the round's outcome is RNG-driven exactly like a natural-trigger round.
