Advisory: We only operate services from the RANDOM.ORG domain. Other sites that claim to be operated by us are impostors. If in doubt, contact us.
RANDOM.ORG's Club Lottery Service helps you run your club or charity lottery. Your winning numbers are picked with the highest quality true randomness from atmospheric noise and logged to immutable audit trails, such that you can prove which winning numbers were generated and when.
The service is designed to be broadcast either through a live stream or by projection to a physical screen in your club, church or hall. This makes drawing the winning numbers a fun and exciting event that is accessible to all your members. After the draw, your members and/or underwriter can use the audit trail to verify the result.
