Last updated: May 2026. All four Feature Buy options tested across the featured AU casinos in April-May 2026.
The Feature Buy menu is what separates Big Bamboo from a standard panda-themed pokie. Instead of grinding 200+ base-game spins waiting for a Free Spins trigger, you can pay a stake multiple to enter a bonus path directly. Push Gaming built four distinct Feature Buy options into the game, each with a different cost, a different bonus entry state, and a different risk-reward profile. This article compares all four side by side and tells you which one to pick (or whether to skip Feature Buys entirely).

The four Feature Buy options
Push Gaming's standard Feature Buy menu on Big Bamboo offers these four paths (exact labels and costs vary slightly by casino deployment, but the structure is consistent):
| # | Option name (general) | Cost (× stake) | What it gets you |
|---|---|---|---|
| 1 | Mystery Bamboo Boost | ~30-50× | Enhanced base-game spin with guaranteed Mystery Bamboo landing |
| 2 | Standard Free Spins entry | ~100-150× | Direct entry to Free Spins with standard starting state |
| 3 | Premium Free Spins | ~250-300× | Direct entry to Free Spins with elevated Mystery Bamboo frequency |
| 4 | Top-tier Mega Buy | ~500× | Direct entry to Free Spins with the strongest starting conditions and largest spin allocation |
Exact numbers vary 5-15% by casino. Always check the in-game Feature Buy menu for live prices before purchasing.
Option 1 — Mystery Bamboo Boost (~30-50× stake)
Cheapest path into the variance. This option doesn't put you into Free Spins; instead, it gives you one base-game spin with a guaranteed Mystery Bamboo landing. The Mystery Bamboo resolves normally — sometimes low-pay, sometimes Golden wild, full distribution.
Expected outcome: roughly 60-80% of the time, this returns less than the purchase cost. Around 15-20% of the time, it lands a Golden wild resolution and returns 100-500× the original stake (net of the buy cost).
Best for: players who want to test the Mystery Bamboo mechanic at controlled cost without going into Free Spins. Streamers like it because the single-spin outcome makes good 30-second clip content.
Worst for: chasing the Free Spins bonus. This option doesn't trigger the round.
Option 2 — Standard Free Spins entry (~100-150× stake)
The "base" Feature Buy. Pays the equivalent of triggering Free Spins with 3 scatters. You get 8 free spins, standard Mystery Bamboo frequency, standard Golden wild rate. Same math as a natural trigger.
Expected outcome: see the Free Spins distribution. Median round pays ~20× stake; top-decile pays 200×+. Net of the ~100× purchase cost, most rounds return slightly negative; occasional rounds deliver multiple-x returns.
Best for: players who want immediate Free Spins access at the cheapest reliable price. Most common Feature Buy choice in our testing.
Worst for: chasers who specifically want enhanced starting conditions. This option gives you a standard round — no boost.
Option 3 — Premium Free Spins (~250-300× stake)
The mid-tier buy. Direct entry to Free Spins with elevated Mystery Bamboo frequency or starting wild positions. Casino implementations vary slightly: some serve this as "Super Free Spins" with double Mystery Bamboo rate, others as "Free Spins with guaranteed Golden wild start."
Expected outcome: rounds run longer and produce more compounded wins on average. Median is roughly 50-80× stake; top-decile reaches 400-800× stake. Net of the ~250× purchase cost, performance is still typically slightly negative on average but the variance distribution is wider.
Best for: Free Spins fans who want a stronger round than the base buy delivers. The Mystery Bamboo frequency boost makes the round more active — more transforms, more decision moments to enjoy.
Worst for: budget players. This is the price point where Feature Buys start to feel expensive per session.
Option 4 — Top-tier Mega Buy (~500× stake)
The "go big or go home" option. Direct entry to Free Spins with the maximum starting conditions: longest spin allocation, highest Mystery Bamboo frequency, often with pre-placed Golden wilds or sticky symbols depending on the casino's implementation.
Expected outcome: the headline-grabbing rounds — when they land — usually come from this buy. Median is 100-150× stake; top-decile reaches 1,000-3,000× stake; the 50,000× ceiling is mathematically reachable but extraordinarily rare (~1 in 100,000+ premium buys).
Best for: high-roller streamers, max-win chasers, and players with the bankroll to absorb multiple ~500× losses while chasing a single big hit.
Worst for: anyone whose session bankroll is less than 5× the buy price. A single premium buy can drain a casual bankroll instantly.
Side-by-side comparison
| Metric | Option 1 | Option 2 | Option 3 | Option 4 |
|---|---|---|---|---|
| Cost (× stake) | 30-50× | 100-150× | 250-300× | 500× |

| Mystery Bamboo frequency | Single guaranteed | Standard FS rate | Elevated | Highest |
| Median return (% of buy cost) | ~50-70% | ~80-100% | ~90-110% | ~100-130% |
| Top 10% return (× buy cost) | 5-15× | 2-4× | 2-4× | 2-6× |
| Best use case | Quick variance test | Standard bonus access | Active bonus round | Max-win chasing |
| Risk of full loss | Moderate | High | High | Very high |
Which option to pick
Honest framework for choosing:
If your session bankroll is < 30× the base stake: Skip Feature Buys entirely. Spin base game, wait for natural triggers. Feature Buys at this bankroll are session-ending bets.
If your bankroll is 30-100× stake: Option 1 (Mystery Bamboo Boost) is the only Feature Buy that makes session-management sense. The cheaper price and self-contained outcome keeps the session alive after a loss.
If your bankroll is 100-500× stake: Option 2 (Standard Free Spins) is the workhorse choice. You can absorb a few losses and still have spins left for base-game play.
If your bankroll is 500-2,000× stake: Option 3 (Premium Free Spins) becomes viable. The elevated round structure delivers more memorable sessions, and the bankroll supports the higher per-buy cost.
If your bankroll is 2,000×+ stake: Option 4 (Top-tier Mega Buy) is in play. Treat it as entertainment expense, not investment.
Feature Buy expected value
Across all four buy options, the expected return is governed by the same RTP framework (96.13% default or 96.52% higher build) as the rest of the game. Push specifically designs Feature Buys to deliver the same long-run RTP as natural-trigger play — they don't subsidise the buys, and they don't punish them either.
Practically: over a long sample of buys, you'll lose roughly 3.87% of your buy spend (at 96.13%) or 3.48% (at 96.52%). Single-session results will vary wildly, but the long-run average is what the math allows.
This means chaining Feature Buys does not create positive EV. If you've lost 3 Premium Buys in a row, the 4th is no more likely to hit. The "I'm due" feeling is gambler's fallacy.
Feature Buys vs welcome bonus
Most casinos' welcome bonus terms exclude Feature Buys from wagering contribution. You can usually still buy them with bonus funds, but the spend doesn't count toward clearing the wagering requirement.
This matters if you're playing through a 30-40× wagering bonus. Feature Buys drain your bonus balance without progressing the wagering — usually worse value than base-game spins for clearance purposes.
Check the specific T&Cs:
- Vegasnova: Feature Buys excluded from welcome wagering.
- Joe Fortune: Feature Buys excluded from welcome wagering.
- GreatSlots: Feature Buys excluded from welcome wagering.
- CasinoRocket: Feature Buys excluded from welcome wagering.
All four featured casinos exclude. This is industry standard for AU-targeting offshore brands.

Quick FAQ
Are Feature Buys legal in Australia? Yes — offshore-licensed casinos serving AU players offer them. Some other jurisdictions (UK, parts of EU) ban Feature Buys; this restriction does not apply at the AU-targeting featured casinos.
Do Feature Buys have better RTP than natural triggers? No — same RTP framework. Some studios advertise marginally different RTP for buys vs natural; Push keeps them aligned.
Can I cancel a Feature Buy mid-purchase? No — once confirmed, the buy executes immediately.
Can I take a screenshot during the buy? Yes — but the outcome is determined by RNG at the moment of purchase, not by what's visible on screen.
Are Feature Buys good for bankroll preservation? No — they're high-variance, high-cost. Base-game spins are better for bankroll-preservation strategies.
Should I chain multiple buys in a row? Only if your bankroll can absorb 3-5 consecutive losses. Otherwise, single buys spaced across base-game play.
Do Feature Buys count toward VIP cashback? Depends on the casino. Some yes, some no. Check the VIP program T&Cs.
Can I use a welcome bonus on Feature Buys? Yes at most casinos — but the spend usually doesn't count toward wagering. Verify the bonus terms.
