Provably Fair

🔒 What is Provably Fair?

Provably fair is a cryptographic system that guarantees every game result on GemRush is predetermined and cannot be manipulated. Before you place a bet, a server seed is generated and locked using SHA-256 hashing. You can verify after every bet that the result was fair.

1
Before Bet
Server generates a secret seed and shows you its SHA-256 hash as proof
2
Game Plays
Result is calculated using HMAC-SHA256 of server seed + client seed + nonce
3
After Bet
Server seed is revealed. Hash it yourself to confirm it matches the pre-bet hash

Verify a Bet

Enter the seeds from any completed bet to independently verify the result.
