A single ticket holder has won around $754.6m (£623.4m) in the US Powerball jackpot but has yet to claim their prize.
The pot is the ninth-largest in U.S. history after a winless streak since November, which allowed the sum to grow into Monday night’s win.
Washington State Lottery officials said the ticket was sold Sunday at a department store in Auburn, 30 miles south of Seattle. He will receive a bonus of $50,000 (£41,000).
The six winning numbers were 5, 11, 22, 23, 69 and – finally – the Powerball 7.
Winners must claim within 180 days or risk losing their money.
The extremely slim odds of winning the Powerball are one in 292.2 million.
The game is designed to attract a large number of players to create big cash prizes – although these often go unclaimed.
Recent jackpots that have yet to be collected include one due to a ticket holder in Maine, who won a $1.35bn (£1.1bn) Mega Millions prize in Januaryand one Record $2.04bn (£1.98bn) Powerball jackpot in California last November.
Monday’s winner has two options: choose a one-time payment of $407.2 million (before taxes) or opt for an annuity.

This means that the money will be distributed in one partial payment made immediately, followed by additional payments over the next 29 years which increase by 5% per year.
The next Powerball draw is scheduled for Wednesday, with a relatively modest estimated jackpot of $20 million.
The biggest lottery jackpot ever in the UK was a £195m won in EuroMillions in July 2022.
