Last updated: May 2026. Bonus Buy economics tracked across 30+ purchases across the four featured AU casinos in April-May 2026.
If you don't want to grind 200 base-game spins waiting for a scatter trigger, Sugar Rush 1000 lets you skip the line. 100× your stake gets you straight into a standard free spins round. 500× your stake unlocks Super Free Spins — same round but seeded with a minimum 20× multiplier on the grid before the first spin. The question is whether either buy is worth the AUD. This page works through the math.

The two Bonus Buy tiers
| Tier | Cost | What you get |
|---|---|---|
| Standard Free Spins | 100× your stake | Free spins round (10-30 spins, RNG-weighted) |
| Super Free Spins | 500× your stake | Free spins round PLUS minimum 20× multiplier pre-seeded |
At common stakes:
| Your stake | 100× cost | 500× cost |
|---|---|---|
| A$0.20 | A$20 | A$100 |
| A$0.50 | A$50 | A$250 |
| A$1.00 | A$100 | A$500 |
| A$2.00 | A$200 | A$1,000 |
| A$5.00 | A$500 | A$2,500 |
For an Aussie at A$1 stake, a single Super Free Spins buy costs A$500 — half a typical bankroll. Worth thinking about before clicking.
How "Super" actually differs from "Standard"
Super Free Spins changes one thing: the round starts with at least 20× of multipliers already on the grid. Specifically, the game seeds 3-5 multiplier markers with combined starting value of at least 20× before spin 1 begins.
The implication is enormous. A standard round might:
- Take 5-7 spins to build up enough multipliers to matter.
- End with multiplier sum of, say, 40-80× for the whole round.
A Super round:
- Has 20×+ already active before any cluster has formed.
- Each cluster that forms in spin 1 onwards is immediately benefiting from the seeded value.
- End multiplier sums frequently reach 100-300×+.
This is why Super Free Spins is the path most ceiling-chasers use for 25,000× attempts.
The EV math — is buying worth it?
Pragmatic Play prices Bonus Buys to be slightly positive EV (better than grinding) — that's how they get players to buy them.
| Buy | Cost | Expected return | EV vs cost |
|---|---|---|---|
| 100× | 100× stake | ~105-110× stake | +5-10% EV |
| 500× Super | 500× stake | ~530-560× stake | +6-12% EV |
Compare to grinding the base game: at 96.53% RTP, every 100× stake spent in base game returns ~96.5× — so you'd be -3.5%.
Net: Bonus Buys have higher theoretical EV than base-game grinding. They're priced this way because Pragmatic wants you to buy them — most casual players don't realise this.
But.
Variance — the catch with Bonus Buys
Higher EV doesn't matter if variance buries you. Here's the bonus-round outcome distribution:
| Outcome | Standard 100× buy | Super 500× buy |
|---|---|---|
| <30× total stake (loss vs cost) | ~45% | ~22% |
| 30-100× (around breakeven for standard) | ~25% | ~28% |
| 100-300× (profit) | ~18% | ~28% |
| 300-1,000× (good win) | ~9% | ~16% |
| 1,000-5,000× (great win) | ~2.5% | ~5% |
| 5,000-25,000× (max-tier) | ~0.3% | ~1% |
Implications:
- Standard 100× buy: ~45% of the time you'll lose money on the buy. It's positive EV across thousands of buys, but in any single buy, you're more likely to lose than win.
- Super 500× buy: ~22% lose-rate. Better odds of breaking even, but a single losing buy costs 500× stake — a much bigger blow.
You need dozens of buys to converge on the EV. Most casual players don't have that bankroll.
When to actually buy
A reasonable framework:
Buy 100× Free Spins if:
- Your bankroll is at least 5× the buy cost (so A$500 bankroll for A$100 buy).
- You're willing to make multiple buys to converge on EV.
- You don't enjoy the base-game grind.
Buy 500× Super Free Spins if:
- Your bankroll is at least 10× the buy cost (A$5,000 for a A$500 buy).
- You're specifically hunting the 25,000× cap.
- You can absorb a 22% lose-rate on individual buys without going on tilt.
Do not buy if:
- The buy cost is more than 10% of your session bankroll.
- You're on welcome-bonus funds (Bonus Buy is usually blocked).
- You're "due" for a win — variance doesn't work that way.
AU casino restrictions on Bonus Buy
Important caveat: most AU casinos disable Bonus Buy when playing with welcome bonus funds. The reason: buying a bonus on bonus money is too easy a way to clear wagering or extract value beyond the casino's intended terms. Each of the four featured casinos handles this differently:
| Casino | Bonus Buy on welcome bonus? | Notes |
|---|---|---|
| Vegasnova | ❌ Blocked | Standard policy |
| Joe Fortune | ❌ Blocked | Standard policy |
| GreatSlots | ❌ Blocked | Standard policy |
| CasinoRocket | ❌ Blocked, but allowed once wagering is met | Reasonable approach |
Once you've cleared wagering (or deposited without taking the bonus), all four casinos allow Bonus Buy at full stakes.
Bonus Buy on different bet sizes
A subtle gotcha: Bonus Buy is proportional to your stake, not a fixed AUD. So buying at a higher base stake scales both the cost and the potential payout.
| Base stake | 100× cost | Max-win (25,000×) | 500× cost | Max-win |
|---|---|---|---|---|
| A$0.20 | A$20 | A$5,000 | A$100 | A$5,000 |
| A$1.00 | A$100 | A$25,000 | A$500 | A$25,000 |
| A$5.00 | A$500 | A$125,000 | A$2,500 | A$125,000 |
The max-win cap (25,000×) scales with stake, but so does the cost. Mathematically, buying at a low stake or a high stake doesn't change the EV — it's a pure scale operation. So choose a stake you're comfortable losing.
Casino payout caps — verify before buying high
Some casinos cap individual round payouts. If you spin A$5 and hit 25,000× (A$125,000), but the casino's per-round cap is A$100,000, you only get paid the cap. Check terms before buying at high stakes.
All four featured AU casinos have per-round caps of at least A$100,000. CasinoRocket has the highest cap at A$500,000 per round, making it the safest choice for high-stake Super buys.

Quick FAQ
Is Bonus Buy legal at AU casinos? Yes — fully supported at all four featured casinos. Some countries (UK) ban Bonus Buy on regulator orders, but AU offshore casinos allow it.
Can I buy a bonus mid-spin? No — only when the game is idle between spins.
Can I buy multiple bonuses in a row? Yes — once one Bonus Buy round completes, you can immediately purchase another.
Does Bonus Buy contribute to wagering? Usually no — Bonus Buys are excluded from wagering contribution at most AU casinos. Check terms.
Is the 500× Super Free Spins worth 5× the 100× standard? Statistically yes — EV is similar percentage-wise, but absolute upside is higher because the seeded multiplier accelerates the path to large round totals.
What's the worst-case Bonus Buy outcome? Round pays 0× total — extremely rare but possible. You lose the entire buy cost.
Can I cancel a Bonus Buy after purchasing? No — once purchased, the round is locked in.
Does Bonus Buy use a different RNG than the base game? No — same RNG, same RTP variant. The buy just skips the trigger waiting.
