If you’re one of those who only buys lottery tickets when the jackpot is really big, this would be a good week to do just that.

Officials with the Missouri Lottery report that Tuesday’s Mega Millions jackpot is now up to an estimated $512-million dollars to a single winner.

That’s the fifth largest jackpot in Mega Millions history.

If you’d rather take the lump sum payment, the cash option is a mere $303.4 million dollars.

Officials remind ticket buyers to play responsibly and put your tickets in a safe place.

Missouri players have until 8:59 p.m. Tuesday to buy Mega Millions tickets.
