Open source

Verify a dice roll or mines layout yourself.

After a server seed is revealed, paste the same inputs used in-game. These pages run the Near Reality algorithm in your browser and never send the seeds anywhere.

00.00 - 100.00

Dice verifier

Reproduce a roll from client seed, revealed server seed, and nonce.

5 x 5 grid

Mines verifier

Reveal the mine tiles for a finished round and compare them to the board you played.

Both games commit to SHA-256(server seed) before you play. When the seed is later revealed, the hash must match that commitment and the outcome must match these pages.
