Tomorrow's Mega Millions lottery drawing could be worth a half billion dollars to the winner.
The estimated jackpot stands at $512 million - and could still grow before the numbers are drawn.
The massive jackpot comes after no ticket matched all five numbers and the Mega Ball Friday night.
The jackpot was last won in Ohio May 4, with a prize worth $142 million. The money was collected by ABC XYZ trust, according to lottery officials.
The prize has only crossed the $400 million mark seven times in its 16-year history, officials said. The top Mega Millions jackpot was $656 million in 2012.
Mega Millions tickets cost $2 per play. The drawing will take place Tuesday at 11 p.m. ET, 8 p.m. PT.
