WASHINGTON (Reuters) - The jackpot for Tuesday night?s U.S. Mega Millions lottery has reached $512 million, the fifth-largest prize in the game?s history, according to the lottery?s website. The next drawing for the prize, which follows 22 that occurred without a jackpot-winning number being called, is scheduled for 11 p.m. In March, a New Jersey man won $533 million, the fourth-largest pot in the game?s history and the second-largest win on a single ticket.
