Hang onto those stocking-stuffer lottery tickets. The Mega Millions jackpot has surpassed $1 billion after no ticket matched all six numbers drawn on Christmas Eve. That means the estimated jackpot for Friday’s drawing is $1.15 billion, potentially the fifth largest jackpot in the game’s history. Lottery officials say the odds of winning the Mega Millions jackpot are 1 in 302,575,350, while the odds of winning any Mega Millions prize are 1 in 24. Tickets for the game are sold in 45 states. Mega Millions tickets are $2 a piece. Half of the proceeds from the sale of each ticket remains in the state where the ticket was sold.
