What happens to unclaimed prizes?
Except for the jackpot (and the Match 5 BONUS prize whenever it is in effect), all unclaimed prizes are kept by the lottery jurisdiction that has the unclaimed winner. The jackpot money and BONUS prize pool are treated differently. If these two prize pools are unclaimed, the money must be returned back to all lotteries, in proportion to their sales for the draw run. The lotteries then distribute the money as they are required by law.
All prizes must be claimed within one year from the date of the drawing, one year from the official close of an instant “scratch” ticket game or a lesser period authorized by the Executive Director for bonus games or drawings. Unclaimed prizes are transferred to the to the General Fund of the District of Columbia.
