The ticket will become void at midnight Saturday.

If the prize is not claimed before then, the money will return to the Big Game lottery, in which six other states also participate: Georgia, Illinois, Maryland, Massachusetts, Michigan and Virginia.

The ticket, which was sold in a Montvale convenience store June 9, 2000, bore the numbers 6, 7, 25, 34, 45. At the time of purchase, the ticket buyer chose the lump-sum payment option of $24 million.
