🔐 Provably fair

Every result = SHA-256(serverSeed : clientSeed : nonce). The server-seed hash below is committed before you play; rotate any time to reveal the seed and verify every past round yourself.

How it works

Provably fair — and honestly fake money.

Two ideas power this simulator: results you can verify, and balances that aren't real. Here's exactly what's going on under the hood — transparency is the whole point.

🔐

Verifiable randomness

Each round is SHA-256(serverSeed : clientSeed : nonce). The hash of the server seed is shown to you before you bet, so it can't be changed afterwards. Rotate the seed any time to reveal it and re-compute every past result yourself.

🏠

The house edge is real

Every game carries a small built-in edge (about 1%), exactly like a real casino. Individual rounds are fair, but the maths means the house wins on average. Your pretend balance drifting down over time is the lesson, not a bug.

🎮

Nothing is real money

Balances are demo credits. There are no deposits, winnings, withdrawals, or prizes — you literally cannot win or lose anything of value. The CoinGecko price just lets you view your pretend balance in a real coin.

This comes from Luck.fyi, where the whole ethos is showing the maths instead of hiding it. A provably-fair casino simulator is the clearest possible way to teach two truths at once: how fairness can be proven, and why — even with perfect fairness — gambling is built for the house to win.

This is a simulator — not a casino, and not encouragement to gamble

No real money is involved here, ever. This page accepts no deposits, pays no winnings, and holds nothing of value. It exists to demonstrate game mechanics and provable fairness, and to make the house edge visible — not to promote real gambling.

Real gambling is high-risk and can be addictive. By design, players lose money over time. Chasing losses, betting more than you can afford, or gambling to escape stress are warning signs. Wins in a demo do not mean you would win for real — the opposite is statistically true.

This simulator is strictly for adults (18+). It is not intended for anyone under 18, and the play-money mechanics here should never be treated as practice for profitable real-money gambling, because no such thing exists over the long run.

If gambling is harming you or someone you care about, free and confidential help is available right now. In the UK: BeGambleAware.org and the National Gambling Helpline on 0808 8020 133 (24/7), or GamCare. Elsewhere, search for your national gambling-support service. You are not alone, and reaching out is a strong move.
Questions, answered

Demo casino FAQ.

Is this real gambling?
No. It's a free play-money simulator for entertainment and education. There's no real wagering, no deposits, no winnings, no withdrawals. Your balance is pretend demo credits that reset whenever you like — nothing of value can be won or lost.
What does "provably fair" mean here?
Each round's outcome comes from a SHA-256 hash of a secret server seed, your client seed and a bet counter (nonce). The hash of the server seed is shown before you play, as a commitment. Rotate the seed any time to reveal it and re-compute every past result yourself — proving nothing was altered after the fact.
Can I win or lose real money?
No — there's no real money anywhere. You can't deposit, cash out, win or lose anything of value. It's a completely risk-free way to see how casino games and provable fairness work.
Why does my demo balance tend to go down?
Because every game has a small house edge, exactly like a real casino. Over many bets the maths guarantees the house wins on average, even though each round is fair. That slow drift down is precisely why real gambling loses money for players over time.
Is real online gambling safe?
Real gambling carries a serious risk of financial harm and can be addictive; most players lose over time by design. Nothing here is encouragement to gamble for real. If gambling is affecting you, free confidential help is available — in the UK, BeGambleAware.org and the National Gambling Helpline on 0808 8020 133. 18+ only.
