How It Works

Enter your client seed, revealed server seed, and nonce to verify a single bet. The tool computes the exact game outcome using Rainbet's cryptographic algorithms (SHA-256 for Mines, HMAC-SHA512 for Keno, HMAC-SHA256 for Plinko). Use the Run Nonces section to compute outcomes across a range of nonces (up to 10,000) with the same seeds and settings.
