Trust Through Mathematics
At GlassHouse, we don't ask you to trust us — we prove fairness mathematically. Every game outcome is determined by cryptographic algorithms that neither you nor we can manipulate. You can verify every single bet independently.
How It Works
Our provably fair system uses a combination of server seeds, client seeds, and nonces to generate game outcomes. Here's the process:
Server Seed Generation
Before you play, we generate a random server seed and show you its SHA-256 hash. The actual seed remains hidden until after your game session ends.
Client Seed (Optional)
You can provide your own client seed to influence the outcome. This ensures we cannot predict or manipulate results even if we wanted to.
Outcome Generation
The game outcome is calculated by combining the server seed, client seed, and a nonce (bet number) using HMAC-SHA256. This produces a deterministic result.
Verification
After your session, we reveal the server seed. You can verify that its hash matches what we showed you before, and recalculate any game outcome yourself.
The Algorithm
// Generate outcome hash hash = HMAC_SHA256(serverSeed, clientSeed + ":" + nonce) // Convert to game result result = hexToFloat(hash.substring(0, 8)) // Example for Crash game crashPoint = Math.max(1, 0.99 / (1 - result))
Why This Matters
We Can't Cheat
The server seed hash is committed before you bet. We cannot change it afterward.
You Can't Predict
You only see the hash, not the seed. You cannot predict outcomes in advance.
Fully Verifiable
Every outcome can be independently verified using standard cryptographic tools.
Instant Results
No waiting for third parties. Results are calculated instantly on our servers.
Verify Your Bets
To verify a bet, you need:
- The revealed server seed
- Your client seed
- The nonce (bet number)
- The server seed hash (to verify the seed is genuine)
You can find verification tools in each game's settings panel, or use any HMAC-SHA256 calculator to verify independently.
