Last updated: May 2026. Demo access verified on all four featured AU casinos plus the Relax Gaming official site during April-May 2026.
Before you put a single AUD into Book of 99, you can play it free — same reels, same Orpheus, same expanding-symbol round, same 99% RTP. Demo mode is the cleanest way to learn the game, test your bankroll strategy, and decide whether a high-variance book slot is the right fit for your style before real money enters the picture. This article covers where to find the demo as an Aussie, what's identical to real-money play, what isn't, and the smart ways to use demo time.

What is the demo?
The Book of 99 demo is a free-play version of the full game. Same provider (Relax Gaming), same software build, same RNG behaviour. If you've never spun a book slot before, the beginner's walkthrough covers the controls and rhythm. You're given a play-money balance (usually A$1,000 or A$5,000) and you can spin until that balance hits zero. Then you refresh the page and the balance resets.
It is not a stripped-down version. The math is the same. The expanding-symbol logic is the same. The 99% RTP is the same. The 12,075× max-win ceiling is the same. The only thing different is the currency — it's pretend money.
Where to play Book of 99 demo in Australia
| Location | Demo available | Registration required |
|---|---|---|
| Vegasnova | ✅ Yes | No (browse without account) |
| Joe Fortune | ✅ Yes | No |
| GreatSlots | ✅ Yes | No (mobile-first, demo prominent) |
| CasinoRocket | ✅ Yes | No |
| Relax Gaming official site | ✅ Yes | No |
| Slot review aggregators (SlotCatalog, Bigwinboard) | ✅ Yes | No |
The most direct path: click any of the four featured AU casinos, navigate to Book of 99 in the slots library, and click "Demo" or "Practice Play" on the game tile. The game loads with a play-money balance.
You don't need to register an account or deposit to access demo at the featured casinos — they expose demos publicly to let players try before signing up.
Demo vs real money — what's the same
| Feature | Demo | Real money |
|---|---|---|
| RTP (99%) | ✅ Same | ✅ Same |
| Volatility | ✅ Same | ✅ Same |
| Max win ceiling (12,075×) | ✅ Same | ✅ Same |
| Free spins trigger rate | ✅ Same | ✅ Same |
| Expanding-symbol probabilities | ✅ Same | ✅ Same |
| Paytable | ✅ Same | ✅ Same |
| Bet range (display only in demo) | ✅ Same | ✅ Same |
| Sound, animations, UI | ✅ Same | ✅ Same |
| RNG behaviour | ✅ Same | ✅ Same |
The math is identical. If you trigger free spins in demo and Orpheus is the expanding symbol, the round plays out exactly as it would on real money — and the displayed win is the same multiplier of your stake. Only the currency is different.
Demo vs real money — what's different
| Difference | Demo | Real money |
|---|---|---|
| Balance is real | ❌ Play money | ✅ Real AUD |
| Welcome bonus applies | ❌ No | ✅ Yes |
| Withdrawals possible | ❌ No (can't withdraw demo wins) | ✅ Yes |
| KYC required | ❌ No | ✅ Yes (before first withdrawal) |
| Bonus Buy enabled | Sometimes ✅ | ✅ Yes (most casinos) |
| Session can end on session loss limit | ❌ No | ✅ Yes |
The most consequential difference: you can't keep demo winnings. If you hit a 12,075× round in demo, it's a A$1,000-balance-resets-to-fake-million screenshot. Cool screenshot, no money.
Why use demo before real money
1. Learn the symbol set. Orpheus is the top high-pay (the full paytable lives in our specs page). Knowing which symbol you want to be the expanding pick saves cognitive load when the bonus triggers for real.
2. Test the variance with your eyes. Specs say "high volatility" — fine. Demo lets you feel what that actually looks like. Burning through a play-money A$1,000 in 200 spins at A$5 stakes without seeing a single bonus trigger is a useful experience. You'll think twice before sitting down with a A$200 real-money bankroll at the same stake.
3. Trigger the bonus at least once. Demo until you trigger at least one free-spins round. See the expanding symbol get chosen, see how it plays out. Now you know what the game's main moment looks like.
4. Verify the RTP variant. The in-game info panel shows the RTP in demo too. If you see 96% in demo at a casino, that's the variant they're running for real money as well. Walk away from that casino.
5. Test your stop-loss discipline. Set yourself a demo session budget — say A$200 of play money. When it's gone, refresh and play again with a strategy adjustment. This is the cheapest training in slot bankroll management you'll ever get.
A 30-minute demo plan
If you have half an hour to spend on demo before depositing real money, do this:
Minute 0-5: Open the game. Verify RTP shows 99% in the info panel. Set bet to A$1. Spin 50 times. Note how many small wins you see, how many dry stretches.
Minute 5-15: Lower bet to A$0.20. Spin 100 times. Watch for the first bonus trigger. If it happens, observe which symbol is chosen as the expanding pick.
Minute 15-25: Raise bet to A$2. Spin until either bonus triggers or balance halves. This shows you what higher-stakes variance feels like.
Minute 25-30: If Bonus Buy is enabled in demo, try one Bonus Buy at A$1 stake. See what 100× cost gets you on average.
After 30 minutes, you've seen at least 200 spins, at least one bonus trigger, and you have a calibrated sense of the game's rhythm. Now you're ready for real money.
Common demo misconceptions
"Demos pay out better to lure you in." False. The Relax Gaming demo runs the same RTP-locked math as real money. There's no "tease" mode.
"If I'm losing on demo, I should switch to real money." No — variance is variance. If you lost on demo, the same math applies to real money. Don't take a demo loss as a signal to deposit.
"If I'm winning on demo, I should switch to real money to lock in the run." No — past wins don't predict future wins. Each spin is independent.
"Demo lets me test bonus buy strategies." Mostly yes — most casinos enable Bonus Buy in demo. But check before relying on it.
Demo on mobile
The demo runs on iOS Safari and Android Chrome identically to desktop:
- Same HTML5 engine.
- Same touch controls.
- Same expanding-symbol round.
- 60fps on flagship phones.
Some casinos require you to land on their site through a desktop browser first, then offer mobile demo via a link. Most just expose demo directly on mobile.
When real money makes more sense
Demo is a learning tool, not a long-term play mode. Once you've:
- Verified RTP is 99% at your chosen casino.
- Watched at least one bonus round play out.
- Calibrated your bankroll and stake size.
- Understood the high-volatility rhythm.
…you've extracted all the value from demo. Beyond that point, demo doesn't teach you anything new — and it doesn't pay. Switch to real money with your welcome bonus, at the smallest bet size you tested, and let the 99% RTP work for you over the long run.
