When you're betting on Cloudbet Originals, every outcome is yours to verify. This free provably fair calculator gives you total control over transparency — no guesswork, no gimmicks. Just pure, provable randomness.

What does "provably fair" mean for your bets?

Provably fair gaming is a cryptographic system that proves — mathematically — that every result in a game was generated fairly. It removes blind trust from the equation. Instead of relying on a casino to be honest, players can verify that no outcome was manipulated. This kind of transparency is a game-changer, especially in online play where there’s no physical wheel, dice, or dealer.

In short, the system ensures that:

1. The randomness is locked in before you play — and can't be changed after.
2. Outcomes cannot be tampered with mid-play.
3. Players can independently verify every result.

It’s like being handed the blueprint to each round — no hidden tricks, no post-spin excuses.

How the Cloudbet provably fair calculator works

Each round in a Cloudbet Originals game (like Mines) runs on a secure, verifiable process:

1. Server seed: Cloudbet’s casino server generates a secret random string before your game begins. This becomes part of the random result generation.
2. Commitment (hash): Before you even click play, a cryptographic hash of the server seed is shared with you. This hash is irreversible, meaning it can’t be faked later.
3. Client seed: You either provide your own client seed or let your browser create one. This gives you a hand in shaping the result.
4. Nonce: A counter that increments every time you play a round using the same seed pair. It ensures every round is unique.

During play, all three elements — server seed, client seed, and nonce — are mixed together in a secure algorithm to generate the outcome. After the round ends, Cloudbet reveals the original server seed, and you can verify the result.

How to verify your game results

After playing, here's how to confirm your outcome was legitimate, or provably fair:

1. Click into the Fairness tab in your game window.
2. Copy the Server Seed, Client Seed, and Nonce shown.
3. Paste those values into the provably fair verification calculator.
4. The tool will show you the result generated by the combined seeds and nonce.
5. Compare that to the outcome you saw in-game. They’ll match if the game result was fair. If there was manipulation, the verification would fail.

Key terms

1. Seed: Random value used to generate results. You get one, and so does Cloudbet.
2. Server seed: Cloudbet’s secret code — locked before play, revealed after.
3. Client seed: Your code — set it yourself or let us randomize it.
4. Nonce: Round counter. Starts at 0, ticks up each time you play.
5. Hash: A secure fingerprint of the server seed — proves it wasn’t changed.
6. Rotate seeds: Refreshing both seeds for more randomness.
7. Hashing: The one-way math that creates unique results from your inputs.
8. Cryptography: The tech behind it all — keeps the system tamper-proof.

FAQs: your provably fair questions answered

Why are the seeds so long and random-looking?

Because randomness is the core of fairness. The long strings of characters prevent both Cloudbet and players from predicting or manipulating outcomes. More entropy = more trust.

Can I change my client seed?

Yes. Head to the fairness settings in the game and enter your own client seed any time. You can rotate it as often as you like.

What if the server seed doesn’t match the original hash?

Then something’s wrong. The whole point of hashing is to prove the seed was locked in before your game started. A mismatch would signal tampering — but with Cloudbet, that won’t happen.

Is the calculator only for Mines?

Right now, we’re rolling it out with Mines, but it will be part of all Cloudbet Originals moving forward.

Do I need to understand cryptography to use this?

Nope. The tool does all the heavy lifting. You just copy, paste, and verify.

What’s a hash exactly?

Think of it like a digital signature. It’s generated by scrambling the server seed using a cryptographic algorithm. If someone tries to alter the seed later, the hash will be different — and you’ll spot the fraud.

Can I use third-party tools to verify results?

Yes. Cloudbet’s system is compatible with independent verification tools, so you can double-check outcomes even outside our platform.

Why does this matter if the games are fun anyway?

Because fairness isn’t a bonus feature — it’s a requirement. When you’re betting crypto, you deserve full control and zero guesswork. Provably fair makes that the default.
