Last updated: May 2026. RTP verified in-game at all four featured AU casinos. Volatility figures from 220 test spins on the 1000 variant.
The RTP and volatility numbers on the 1000 variant tell two stories. The RTP — 96.50% in the default build — is the same as the original. The volatility is also identical on Pragmatic Play's official spec sheet: very high. But under the hood, the 1000's variance distribution has a noticeably longer right tail because the 1,000× orb extends the rare-huge-win zone. This article unpacks what those two numbers actually mean for an Aussie pokie session and how to verify the RTP your casino is running.

What 96.50% RTP actually means
RTP = Return to Player. It's the long-run average of how much wagered money the game pays back to players. 96.50% means that across millions of spins, the game returns AU$96.50 for every AU$100 wagered. The remaining AU$3.50 is the house edge.
Crucially:
- It's a long-run average, not a session prediction. Any individual session can be 0% (lost everything) or 5,000% (15,000× win on a single spin).
- It's the certified default. Pragmatic Play ships the 1000 variant with multiple RTP builds. Casinos choose which to deploy.
- It's the same as the original. The 1000 doesn't change RTP — only variance distribution. Your long-run expected return is identical to the original.
The RTP variant trap — same as the original
This is the single most important thing to know about Gates of Olympus 1000 before depositing.
Pragmatic Play ships the 1000 variant in three RTP builds:
| Build | RTP | What it means |
|---|---|---|
| Default (certified) | 96.50% | The version Pragmatic Play certifies and casinos advertise |
| Reduced (mid) | 95.50% | A casino-deployed reduced variant — 1% more house edge |
| Reduced (low) | 94.50% | A casino-deployed reduced variant — 2% more house edge |
The visual game is identical across all three. The math is not. Across a typical 1,000-spin session at A$1.00 stake:
- 96.50% build: expected loss = A$35
- 95.50% build: expected loss = A$45 (an extra A$10)
- 94.50% build: expected loss = A$55 (an extra A$20)
Over a regular playing month with many sessions, the 94.50% build costs you tens or hundreds of dollars more in expected losses for the same game.
How to verify the RTP at your casino
This is a 30-second check, and it's worth doing before every new casino.
- Open Gates of Olympus 1000 at the casino (in real money or demo — same number applies).
- Tap the menu icon (top-left in most layouts).
- Select Game Info / Paytable & RTP / Info (the wording varies by casino).
- Look for "Return to Player" or "RTP" in the info panel.
- You want to see 96.50% or 96.5%. Anything less is a reduced build.
| Casino | RTP build (verified May 2026) |
|---|---|
| Vegasnova | 96.50% (certified default) |
| Joe Fortune | 96.50% (certified default) |
| GreatSlots | 96.50% (certified default) |
| CasinoRocket | 96.50% (certified default) |
All four featured AU casinos run the certified default. Unknown offshore brands often run the 94.50% build.
What "very high volatility" feels like in practice
Volatility (sometimes called variance) measures the spread of outcomes around the RTP average. A low-volatility pokie returns close to 96.50% every session — small frequent wins, no big spikes. A very-high-volatility pokie like the 1000 returns 96.50% across millions of spins but wildly different amounts per session.
In practice for the 1000 variant:
- ~75-80% of base-game spins return zero. You'll burn through long stretches of dry spins between any payout.
- ~22% of spins return some payout, mostly small (under 2× stake).
- ~0.3% of spins (without Ante Bet) trigger the free spins bonus — the round where the actual money is.
- Bonus rounds vary wildly — most return between 50× and 400× of stake; some return less than 100× (a "small bonus"); rare ones return 1,000×+.
A typical 30-minute session at A$1.00 stake (roughly 350-450 spins):
- ~75% of sessions: you'll lose money. Down A$20-A$50 on the deposit.
- ~20% of sessions: you hit a bonus round, recover most of the deposit, finish slightly up or even.
- ~5% of sessions: you hit a bonus round that pays 500×+ of stake, finish well up.
- Rarer than 1%: the kind of session you'll talk about for years.
Variance comparison: 1000 vs original
The 1000's variance distribution shifts slightly to the right of the original. The 1,000× orb in the multiplier pool pulls the rare-huge-win zone outward.
| Outcome zone | Original frequency | 1000 frequency |
|---|---|---|
| Bonus round 50×–200× | Common | Common |
| Bonus round 200×–500× | Common | Common |
| Bonus round 500×–1,000× | Uncommon | Uncommon |
| Bonus round 1,000×–2,500× | Rare | Slightly more often |
| Bonus round 2,500×–5,000× | Very rare | Rare |
| Bonus round 5,000×+ | Impossible (cap) | Rare-but-possible |
| Bonus round 10,000×+ | Impossible | Very rare |
| Bonus round 15,000× | Impossible | Theoretical ceiling |
The "average bonus round" is almost identical between the original and the 1000. The difference is what's possible at the extremes.
Practical RTP & variance tips
- Verify the RTP before every deposit at a new casino. 30 seconds, saves you 1-2% house edge.
- Don't expect 96.50% in your session. Variance dominates the short run. A losing 100-spin session is normal even on the certified build.
- Bankroll for variance, not RTP. Plan to lose what you've deposited. If you don't, anything you take home is upside.
- Bonus Buys average to RTP but with even higher variance per buy. A 100× Bonus Buy returns 96.50% on average — but each individual Buy is its own variance bet.
- Ante Bet does NOT change RTP. It changes scatter frequency only. RTP holds at 96.50% with Ante Bet on or off.
Math comparison: Ante Bet on vs off
A common confusion: Ante Bet costs +25% per spin and roughly doubles bonus trigger frequency. Does that change RTP?
No. The game is balanced so the extra cost is offset by more frequent bonus triggers. Both modes return ~96.50% over the long run.
What it changes is your session shape:
| Mode | Cost per spin (at A$1.00 base) | Bonus trigger frequency (approx) | Session shape |
|---|---|---|---|
| Ante Bet off | A$1.00 | 1 in 250 spins | Longer dry stretches, less bonus action |
| Ante Bet on | A$1.25 | 1 in 125 spins | More frequent bonus rounds, faster bankroll burn between |
Most recreational AU players prefer Ante Bet on because the more frequent bonus action feels better.
House edge breakdown
The 3.50% house edge on the 1000 (96.50% RTP build) is divided across game outcomes:
| Outcome category | Approximate contribution to RTP |
|---|---|
| Base game wins (8-9 symbols) | ~25% |
| Base game wins (10-11 symbols) | ~15% |
| Base game wins (12+ symbols) | ~5% |
| Base-game multiplier orbs | ~7% |
| Free spins round (typical 50×-400× rounds) | ~30% |
| Free spins round (rare 1,000×+ rounds) | ~10% |
| Free spins round (very rare 5,000×+ rounds) | ~4.5% |
| Total RTP | ~96.5% |
The 1000's specific 1,000× orb feeds the bottom row of that table — the rare-huge-win zone. It doesn't add return; it redistributes existing return into a longer tail.

Quick FAQ
Is 96.50% RTP good for a slot? It's above average for an online slot (industry typical is 95-96%). The 1000 sits in the upper tier alongside the original.
Why do casinos run 94.50% builds? More house edge. The visual game is the same, so most players never check.
Is volatility the same as variance? Functionally yes — both describe the spread of outcomes around the average.
Does Ante Bet improve my chances of winning? No — it changes session shape (more bonus rounds), not RTP. Long-run expected return is identical.
Will I actually see 15,000× wins? They exist (Pragmatic certifies the ceiling), but they're extraordinarily rare. Over a typical year of regular play, you might see one 5,000×+ event total. 15,000× is multi-year-rare.
Can I improve RTP with strategy? No — slot RNG ignores your decisions. Pick a 96.50% casino and pick a bet you can afford; that's the entire decision set.
