Demo Games
Free-to-play, provably-fair clones of the originals you'd find on Stake, Roobet and Shuffle. No real money — your demo balance lives in this browser via localStorage. The provably-fair machinery (server seed, client seed, nonce, HMAC-SHA256) is real and verifiable: rotate the seed any time and re-run the HMAC yourself for every nonce.

How "provably fair" works here: before any bet, a random server seed is generated and its
SHA-256 hash is committed (visible to you). Each bet rolls HMAC-SHA256(server_seed, client_seed:nonce). When you rotate the server seed, the original is revealed — re-run the HMAC for every nonce yourself and confirm every result was determined the moment you placed the bet. The client seed is fully under your control.
