Lottery tickets erroneously printed, defective in any way, or mutilated when received by Sales Agent are to be returned by the Sales Agent immediately to the Lottery. Credit may be allowed for said tickets. Each ticket, to obtain credit or to claim a prize, must contain with legible certainty the Lottery number or winning symbols, serial number, and, if applicable, the drawing date. Unless the Director determines that a mutilated Lottery or otherwise defective or invalid ticket is genuine, no credit or prize will be issued to the holder of said ticket.
