Last updated: May 2026. RTP variants verified in-game at all four featured AU casinos. All four currently run the 96.31% certified default.
This is the single most important article on this site for Pirate Bonanza players who care about their bankroll. Backseat Gaming ships the game in two RTP variants — and casinos choose which one to deploy. The visuals are identical. The math is not. If you spin real AUD on the lower variant without realising it, you're handing the house an extra 2.05 percentage points of edge for no reason. This article tells you exactly what the variants are, how to check which one you're playing, and which casinos run the certified default.

The two variants
| Variant | RTP | House edge | Who runs it |
|---|---|---|---|
| Certified default | 96.31% | 3.69% | Reputable AU brands, including all 4 featured |
| Reduced | 94.26% | 5.74% | Some unknown offshore brands, AU-targeting promoters without strong vetting |
The spread is 2.05 percentage points. Smaller than the 8-point spread on Wanted Dead or a Wild (where Hacksaw ships four variants), but still significant — and still worth checking before you play.
What that 2.05% actually costs you
The headline RTP isn't a per-spin payout. It's the expected return on turnover over a very large sample of spins. The way to feel the impact: convert it to house edge.
- 96.31% variant — house edge is 3.69%. Spin A$1,000 of total wagered, expected house take is A$36.90.
- 94.26% variant — house edge is 5.74%. Spin A$1,000 of total wagered, expected house take is A$57.40.
That's A$20.50 more per A$1,000 wagered on the lower variant — a 55% larger house take from your bankroll. Over a year of regular play, that's hundreds of dollars handed to a casino for no benefit. Same game, same animations, same chance at the 15,000× max — but more of your money walks out the door.
How to check which variant a casino is running
Two-minute check before you deposit:
- Load Pirate Bonanza at the casino (demo mode is fine).
- Tap the info icon (i) in the bottom-left corner of the game window.
- Scroll to the RTP field.
- Read the number.
- 96.31% — certified default. Safe to play.
- 94.26% — reduced variant. Close the tab. Find another casino.
That's it. Two minutes, zero deposit risk. There's no excuse to skip this step.

Why casinos run reduced variants
It's a commercial choice. Backseat Gaming offers the lower variant as a "casino margin enhancement" — operators that take it get a worse player experience but a fatter monthly margin on the game. Reputable casinos with sustainable business models stick to the certified default (they make money on volume and player retention, not by cranking edge). Less reputable operators sometimes deploy the reduced variant on the assumption that 90% of players won't notice.
The variant is a casino-side configuration, not a player-side switch. You can't change which one you're playing. Your only lever is which casino you deposit at.
How common is the reduced variant?
We monitor RTP variants across roughly 30 AU-targeting casino brands every quarter. The 94.26% variant of Pirate Bonanza turns up at around 5-10% of brands at any given time — uncommon, but not rare.
The brands most likely to run the reduced variant are:
- Newly-launched offshore brands chasing margin in their first 6 months.
- AU-targeting brands without strong affiliate vetting (where reviewers don't check RTP, the casino assumes players won't either).
- Brands aggressively advertising on Telegram, Reddit, and forums with no track record.
The four featured casinos all run the certified default because their commercial model relies on player lifetime value, not single-session edge.
A worked example
Let's say you deposit A$200 and play at A$0.50 per spin for an evening. You're aiming for 300 spins = A$150 of total turnover.
On 96.31%:
- Expected return: A$144.47.
- Expected loss: A$5.54.
On 94.26%:
- Expected return: A$141.39.
- Expected loss: A$8.61.
Difference: A$3.07 of expected loss on a single session. Small at the per-session level. Multiply by 50 sessions a year and it's A$150+ of additional expected loss for zero gameplay benefit.
At higher stakes — say a A$5 bet over 200 spins (A$1,000 turnover) — the difference per session climbs to A$20.50. Over a year of weekly sessions, that's over A$1,000 of additional expected loss.
Other Backseat Gaming titles — variant patterns
Backseat tends to ship two-variant RTP structures consistently across the catalogue:
- Pirate Bonanza — 96.31% / 94.26%.
- Pirate Bonanza 2 — 96.32% / 94.27% (slightly different default, same pattern).
- Other Backseat titles — typically 96.2-96.4% certified, with reduced builds around 94.2-94.4%.
If you play Backseat titles regularly, always check the in-game info panel on each new title — the casino may run different variants on different games.
Compare with Hacksaw (sister studio)
Hacksaw Gaming ships four-variant RTP structures (96.38% / 94.55% / 92.33% / 88.42% on Wanted Dead or a Wild, for example). Backseat ships two-variant structures.
Why the difference? Hacksaw's older catalogue was built when "RTP segmentation" was the studio's standard B2B model. Backseat, launched in 2024, ships fewer variants per game — a simpler model that's also easier for players to police. Net result: Backseat games have a smaller worst-case downside than Hacksaw games. But both studios put the burden on the player to check.
Why doesn't the casino tell me upfront?
Some do. Most don't. Casino marketing pages tend to advertise "Backseat Gaming — high RTP" without specifying which variant. Some casinos publish RTP per-game in their footer / terms; most don't.
The in-game info panel is the legally-binding source of truth — the RTP shown there is the live deployed math, audited by GLI / iTech Labs. Always trust the in-game panel over any marketing claim.
What to do if you discover you've been playing the reduced variant
- Stop playing. Don't try to "make it back" — the math is worse and chasing won't fix it.
- Request a withdrawal of your remaining balance (PayID is the fastest path — see our banking guide).
- Switch casinos. Use one of the four featured here, all of which run the 96.31% default.
- Don't expect a refund. The casino was running a legal variant. Your prior play is not refundable.
The lesson is preventive: check the variant before depositing, every time, at every new casino.

Quick FAQ
Is the 94.26% variant illegal? No — it's a certified math variant the studio ships. Casinos that deploy it are doing so legally. It's just worse for the player.
Can the variant change while I'm playing? Not within a session. Casinos can switch between updates / maintenance windows, so the variant you saw last month isn't guaranteed today. Re-check periodically.
Does demo mode show the same RTP as real money? Yes — the demo runs on the same deployed variant. This is the trick: if demo shows 94.26%, real money is also 94.26%.
Are there even worse variants out there? Not on Pirate Bonanza. The studio ships only the two variants on this title.
What's the impact on max win at the lower variant? None — the 15,000× ceiling is the same on both variants. The lower variant just means you'll reach the average more slowly in the wrong direction (the RTP is your money flow, not the max win).
Should I switch casinos every time? No — if you've verified your current casino runs 96.31%, stay put and re-check quarterly. Don't switch on a rumour.
