Last updated: May 2026. Instant Prize purchases tested across all four featured AU casinos in April-May 2026 with 50+ purchases recorded.
The Instant Prize is Big Bamboo's strangest feature — and the one that confuses new players the most. It's not part of the regular spin loop. It's not a bonus round. It's a one-press purchase mechanic that costs your stake and returns a multiplier between 1× and 5,000× your stake instantly. Think of it as a side-bet wheel-spin grafted onto the pokie. This article covers exactly how it works, the realistic probability distribution, when it's worth using, and when to skip it.

What the Instant Prize is
A separate purchase mechanic with its own button — usually located near the bet panel or in the Feature Buy menu, labelled "Instant Prize" or similar. Pressing it:
- Deducts your current stake from your balance.
- Spins a hidden multiplier wheel.
- Returns a multiplier between 1× and 5,000× to your balance.
The transaction is one-shot. You pay once, you get one multiplier back. There's no follow-up spin, no chained outcome, no bonus round. It's a fixed-cost, variable-return side bet.
How it differs from the Free Spins bonus
Critical distinction:
| Feature | Cost | Returns | Round time |
|---|---|---|---|
| Free Spins (natural trigger or Feature Buy) | Buy: 100-500× stake; Natural: free | Variable; capped at 50,000× total | ~60-120 seconds |
| Instant Prize | Single stake (e.g. A$1) | Variable; capped at 5,000× | Instant |
The Instant Prize is cheap to enter (A$1 at A$1 stake) but capped much lower (5,000× vs 50,000×). It's a quick variance shot, not a path to max-win.
The probability distribution
Push Gaming doesn't publish the official Instant Prize probability table. From 50+ test purchases during our testing, the observed distribution looks like:
| Multiplier returned | Approximate frequency |
|---|---|
| 1× (just gives your stake back) | ~30% |
| 2-5× | ~30% |
| 5-10× | ~18% |
| 10-25× | ~10% |
| 25-50× | ~6% |
| 50-100× | ~3% |
| 100-500× | ~2% |
| 500-1,000× | ~0.5% |
| 1,000-5,000× | ~0.2% |
| 5,000× (the cap) | ~0.05% |
So roughly 60% of Instant Prize purchases return 5× or less, and 30% just return your stake back (the 1× outcome). The median outcome is around 2-3×.
For the Instant Prize to be a positive-expected-value bet, the long-run average payout would need to exceed 1× (the cost). The observed average across our 50 purchases hovered around 0.85-0.95×, which is consistent with the game's overall RTP — the Instant Prize isn't free EV; it's the same house edge as the rest of the game, just delivered in a different shape.
When to use it
The Instant Prize is best used for:
- Variance entertainment. You want a quick "win or lose" moment without playing through 50 base-game spins.
- Session breaks. Between dry stretches, an Instant Prize gives a quick adrenaline shot without committing to another auto-spin set.
- Stake-up demonstration. If you've just had a small win and want to see what a single concentrated bet does, the Instant Prize is the cleanest test.
- Showcase plays. Streamers use it for short-clip content because the result is instant and visual.
When to skip it
The Instant Prize is best skipped when:
- You're chasing the 50,000× max-win. Instant Prize caps at 5,000× — wrong tool.
- Your bankroll is tight. Instant Prize is essentially a coin-flip on a 2-5× return; the 30% "just gives stake back" outcome is the most common single result. Better to spin the base game for slower but more consistent variance.
- You're working through bonus wagering. Some casinos exclude Instant Prize purchases from bonus wagering contribution. Check the casino's T&Cs.
- You don't enjoy variance for its own sake. Some players hate the Instant Prize because most outcomes feel anticlimactic.
The 5,000× hit — how rare is it?
The ceiling outcome (5,000× return on a single purchase) is genuinely rare. From our 50 test purchases, we didn't hit it once. Streamer-clip databases show 5,000× Instant Prize hits exist but are infrequent — roughly the same rarity as a 1,000×+ Free Spins round.
If you do hit it: from a A$1 purchase you get A$5,000 back. From a A$10 purchase, A$50,000. From a A$100 purchase, A$500,000 (though most casinos cap individual payouts below this — check T&Cs).
Instant Prize vs Feature Buy vs base game — which is best EV?
All three paths have the same house edge because they all flow through the same RTP framework (96.13% default or 96.52% higher build). The expected return is identical. What differs is the variance shape:
| Path | Variance shape | Best for |
|---|---|---|
| Base-game spins | Low per-spin variance, long sessions | Patient sessions, bankroll preservation |
| Instant Prize | High single-shot variance, short outcome | Quick variance hits, no commitment |
| Feature Buy | Highest variance per transaction, immediate big-round access | Bonus chasing, time-skipping the grind |
Pick the path that matches your mood and bankroll for the session. None is "better" — they're variance-shape choices.
Instant Prize stacking — can you buy multiple?
Yes, in principle. There's no in-game limit on how many Instant Prizes you can buy back-to-back. Some players chain 10-20 purchases hoping one delivers a 100×+ return.
The math: 10 purchases at A$1 each costs A$10. The expected return is ~A$9.50 (slightly negative EV). Most chains lose a few dollars. Occasionally a chain delivers a 100× hit that covers all the losses and more. This is gambling, not investing — don't expect a positive outcome from chaining.
Featured casinos — Instant Prize availability
| Casino | Instant Prize available | Notes |
|---|---|---|
| Vegasnova | Yes | Standard implementation |
| Joe Fortune | Yes | Standard implementation |
| GreatSlots | Yes | Standard; smooth mobile UI |
| CasinoRocket | Yes | Standard; runs the 96.52% higher RTP build |
All four featured casinos serve the Instant Prize feature. The cost and return distribution is identical at each — the feature is part of Push's core game implementation and isn't operator-configurable.
Instant Prize and the Gamble feature
The Gamble feature (article #02 covers it) works on standard wins but not directly on Instant Prize returns at most casinos. So you can't double an Instant Prize hit via the gamble screen. If the Instant Prize returns 50×, that's the final number on that transaction.

Quick FAQ
Is the Instant Prize the same as the Feature Buy? No — Feature Buy puts you into Free Spins (a multi-spin bonus round). Instant Prize is a single-press multiplier purchase. Different mechanics.
Can I lose more than my stake on a single Instant Prize? No — the cost is fixed at your current stake. The return can be 1× (your stake back) or higher.
Will the casino refund a 1× return? No — 1× is a valid outcome (it returns your stake, costing you nothing but giving you nothing). It's a built-in result, not a casino error.
Is the Instant Prize affected by the RTP variant? Yes — both the 96.13% and 96.52% configurations include the Instant Prize, but the 96.52% build distributes slightly more value to the side feature. Difference is small.
Does Instant Prize count toward wagering? Depends on the casino. Some yes, some no. Check the bonus T&Cs.
Can I buy Instant Prize during Free Spins? No — only available in base game.
Is the Instant Prize "rigged"? No — it's RNG-driven with the same independent certification as the rest of the game.
Should I demo it before buying? Yes — Push Gaming's demo mode includes Instant Prize purchases on play credits. Use the demo to see the distribution before spending real money.
