A single ticketholder has won an estimated $754.6m (£623.4m) in the US Powerball jackpot but is yet to claim their prize.
The pot is the ninth-largest in US history after a winless streak since November allowed the sum to grow until Monday night’s win.
Washington state lottery officials said the ticket was sold in a department store in Auburn, 30 miles (48km) south of Seattle, on Sunday. It will receive a $50,000 (£41,000) bonus.
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 cash.
The extremely slim odds of winning the Powerball are one in 292.2 million.
The game is designed to draw vast numbers of players to build big cash prizes – although these often remain unclaimed.

Monday’s winner has two options: to choose a one-time payment of $407.2m (before tax), or opt for an annuity.

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