Before opening seals, all unsold tickets must be secured and made unavailable for sale. All unsold squares on a grid must be marked "VOID". The organization must retain all flares and unsold tickets in their records for 3½ years.
Game scores posted by the applicable league are considered official and will be used to determine the winning numbers on the sports tipboard. Posting the results of the professional sporting event to the flare or grid in permanent ink is required (this is not considered altering the flare).
