How is Satoshi Mines Provably Fair?

This game uses “game hashes” to prove itself. If you've played provably fair games online before, Satoshi Mines' method will be familiar to you.

What are the game hashes?

Game hashes are how Satoshi Mines proves that each game's mine tiles are chosen when the game is created and are not tampered with. Hashes thus prove to the player that the game is fair.

When a new round is started, three of the twenty-five tiles are chosen as mines. The three tiles (represented as numbers from 1 to 25,) coupled with a random string generated by the server are hashed using SHA256. The result of the hash function is shown to you before you make your first tile choice.

Validating the fairness

After a game has been completed, the "three-number+random string" secret will be revealed. It is at this point you may validate that the SHA256 hash of the secret matches the hash that has been shown since the beginning of the round.
