THE CHART GAMES

Fairness

Every round can be verified

Our games run on our servers, never in the player's browser. Each round uses its own random server seed (32 bytes from the operating system's cryptographic generator).

How it works

  • Before the result is shown, the round records sha256(serverSeed).
  • Random numbers are drawn from HMAC-SHA256(serverSeed, `${sessionId}:0:${cursor}`), four bytes per number.
  • After the round, the server seed is revealed in the game, in the partner portal and through the API (GET /partner/rounds/{id}).
  • Anyone can check that the seed matches its hash and recompute the result with the published game rules.

Mathematics

Each game page publishes its return to player (RTP), volatility and maximum win. RTP figures come from the game's rules and are confirmed by simulating millions of rounds before release.

Certification

Games are submitted to an independent testing laboratory for RNG and maths certification; the laboratory and certificate are shown on each game page once issued.
