Mega Millions prize up to $654 million, 4th largest in US history Associated Press · October 15, 2018 at 6:31 pm DES MOINES, Iowa (AP) – After nearly three months without a winner, the Mega Millions lottery game has climbed to an estimated $654 million jackpot. Unfortunately, even as the big prize for Tuesday night’s drawing increases to the fourth-largest in U.S. history , the odds of matching all six numbers and winning the game don’t improve. They’re stuck at a miserable one in 302.5 million. The last time anyone won the jackpot was July 24, when a group from California claimed a $543 million prize. The estimated $654 million jackpot refers to the annuity option, paid out over 29 years. The cash option, which is favored by nearly all winners, is $372 million. Mega Millions is played in 44 states, Washington, D.C., and the U.S. Virgin Islands. Copyright 2018 The Associated Press.
