Card games
When you open the game page the server generates a secret and a seed and reveals its hash (using HMAC SHA256 algorithm). The server secret represents randomly shuffled card deck. The server seed is a cryptographically secure random alpha-numeric string. The hash of these 2 strings helps to ensure that the initial card deck is not altered after you choose the bet amount. After the game is finished the server secret and the server seed are revealed, so you can easily calculate and verify the hash.
