Last updated: May 2026. RTP variants verified in-game across all four featured AU casinos in April-May 2026.
Push Gaming, like most modern slot studios, ships Big Bamboo in multiple RTP configurations. Operators choose which build to deploy. The visual game is identical — same Mystery Bamboo, same Golden Bamboo wilds, same Free Spins round, same 50,000× ceiling. But the math underneath is different, and over a long session the gap costs real money. This article explains the two builds, how to verify which one your casino is running, and why the difference matters more than the small numerical gap suggests.

The two builds
| Configuration | RTP | Notes |
|---|---|---|
| Default | 96.13% | Standard licensing tier; the build most operators deploy |
| Optional higher build | 96.52% | Licensed at premium tier; some operators pay extra for it |
That's the entire list — Big Bamboo doesn't ship sub-96% configurations the way some other studios' titles do. Push Gaming's licensing structure caps the variance between the two builds at roughly 0.4 percentage points. Compare with Hacksaw Gaming's Wanted Dead or a Wild (96.38% / 94.55% / 92.33% / 88.42% — a near-8-point spread), and you'll see Push is at the conservative end of variant deployment.
What 0.4 percentage points actually costs
It looks small on paper. Run the math:
| Session size | Difference between 96.13% and 96.52% |
|---|---|
| 1,000 spins at A$1 = A$1,000 wagered | A$3.90 |
| 1,000 spins at A$5 = A$5,000 wagered | A$19.50 |
| 10,000 spins at A$1 = A$10,000 wagered | A$39.00 |
| 100,000 lifetime spins at A$1 = A$100,000 wagered | A$390.00 |
Across a single weekend session of 1,000 spins, the difference is the price of two beers at a Sydney pub — not life-changing. Across a lifetime of pokie play on this title, the difference is meaningful. If two casinos offer otherwise-comparable experiences and one runs the 96.52% build, that's the one to use.
How to verify the RTP in-game
The verification process is the same on every casino:
- Load Big Bamboo. Open the game in your browser (no need to spin yet).
- Click the (i) info icon. Usually bottom-left corner of the game UI. Sometimes labelled "Paytable" or "Help."
- Scroll to "Theoretical Return to Player" or "RTP." Push games typically place this near the top of the info panel.
- Read the figure. It should be either 96.13% or 96.52%. Anything below 96% is a red flag — Push doesn't license sub-96% builds, so an unlabelled lower figure means the casino is running an unauthorised modification or you're on a fake game tile. Close the tab.
This takes 30 seconds. Do it every time you play at a casino you haven't recently verified, because casinos can swap variants without notice during contract renewals.
Featured casinos — RTP build deployed
Verified in-game during May 2026:
| Casino | RTP build | Notes |
|---|---|---|
| Vegasnova | 96.13% default | Standard tier; the casino prioritises throughput on Push catalogue volume rather than premium variant licensing |
| Joe Fortune | 96.13% default (96.52% on promo weekends) | Periodically swaps to higher build during weekend promotions; check the info panel before depositing |
| GreatSlots | 96.13% default | Standard tier; the value proposition here is the A$10 minimum entry, not the RTP |
| CasinoRocket | 96.52% higher build | The standout: licensed the premium tier and runs it consistently; best long-run value of the four for this game |
CasinoRocket is the best RTP pick for high-stakes or high-volume players. The other three are still decent — 96.13% is above industry median — but if you're serious about long-run expected return, CasinoRocket is mathematically the right choice.
Why casinos run different builds
It's a cost decision on the operator side. Push Gaming charges higher licensing fees for the 96.52% build because the casino's expected margin is smaller (3.48% house edge vs 3.87%). Casinos with tight margins or aggressive volume strategies often stick to the default; casinos chasing high-roller traffic or differentiation often pay for the higher tier.
Some operators also run dual builds — they license both and deploy the 96.52% to high-roller accounts via the VIP backend while serving the 96.13% to general traffic. This is rare and not always disclosed, but if you're VIP-tiered at a casino, ask the support team which build your account sees.
What about the 96.52% build during Free Spins?
Both builds preserve the same Free Spins round structure, the same Mystery Bamboo weights inside the bonus, the same Golden Bamboo wild frequencies, and the same 50,000× ceiling. The difference is distributed across base-game outcomes — not concentrated in the bonus. So the 96.52% build doesn't make max-win hits more likely; it makes base-game grind slightly less expensive.
How often do casinos swap variants?
In our experience, rarely without notice on the four featured brands. Across 12 months of monthly RTP-variant checks on Push titles at these casinos, we've seen one swap (a promotional weekend at Joe Fortune running 96.52% as a marketing push). Unfamiliar offshore brands swap variants more often — sometimes monthly, sometimes when traffic patterns change. The lesson: re-verify the info panel any time you return to a casino after a multi-month gap.
RTP variants and the welcome bonus
Welcome-bonus play often runs on the same RTP variant as regular play. But some casinos quietly deploy a lower-margin (for them) build for bonus-funded play specifically. This is rare on regulated frameworks but not unheard of in less-regulated jurisdictions.
If you're playing through wagering requirements and the in-game RTP figure changes from your pre-bonus check, screenshot the variant change and contact support. Variant downgrades during bonus play are a violation of most ADR (alternative dispute resolution) frameworks.
Comparison with other Push catalogue RTP profiles
To put Big Bamboo's 96.13% / 96.52% in context within the studio:
| Push title | Default RTP | Higher build | Spread |
|---|---|---|---|
| Big Bamboo | 96.13% | 96.52% | 0.39% |
| Razor Shark | 96.70% | n/a (single build) | — |
| Razor Returns | 96.78% | n/a (single build) | — |
| Jammin' Jars 2 | 96.40% | 96.84% | 0.44% |
| Mystery Museum | 96.55% | n/a (single build) | — |
Big Bamboo's spread is typical for Push's variant-shipping titles. The studio tends to either ship single-build games or ship two builds with a small spread — they don't deploy the giant variance ranges that some lower-tier studios use.
What to do if your casino runs a lower-than-advertised RTP
This shouldn't happen at the four featured casinos, but if you ever find an in-game RTP below 96.13% on Big Bamboo:
- Screenshot the info panel immediately.
- Don't deposit. Or if you already deposited, withdraw any remaining balance.
- Contact casino support and ask which RTP variant they've licensed. Compare their answer to your screenshot.
- If there's a mismatch, escalate to the casino's ADR channel (listed in their T&Cs footer).
- Switch to a verified casino — see our shortlist of vetted AU casinos for the four featured options.

Quick FAQ
Why does Push ship two RTP builds at all? Standard industry practice — gives operators flexibility on house-edge positioning. Not a Push-specific quirk.
Can I tell from the casino's website which build they run? Sometimes — casinos may advertise "96.52% RTP" on the game's marketing page. But always verify in-game: marketing copy can lag the live config.
Does the demo run the same RTP as real-money? Yes at the four featured casinos. Verify with the info panel in both modes if you're unsure.
Is 96.52% the best Big Bamboo RTP available? Yes — Push doesn't license a higher build. 96.52% is the ceiling.
Will the casino warn me if they swap variants? Usually no. RTP changes are operational, not communicated. Re-verify periodically.
Is the 0.4-point spread worth switching casinos for? Over a 1,000-spin session at A$1 stake, the expected difference is A$3.90. Over a lifetime of play on this title, it's hundreds of dollars. Worth it if other casino factors are equal.
Are RTP variants regulated? Yes — Push must disclose the variant in the info panel under MGA/UKGC frameworks. The reason verification is possible is regulatory disclosure.
Can I request the higher build from a casino running the default? Some VIP programs honour this. Most don't. Worth asking if you're high-volume.
