Start the session
Lucky Squares creates the commitment before the first protected random call.
Verifiable random calling
Provably Fair Calling
Give every random call a tamper-evident record that can be checked after the game.
Lucky Squares commits to the random-calling sequence when the session begins, protects every call in a cryptographic hash chain, and produces an exportable audit or printable fairness certificate.
