A life-changing Lotto Rollover jackpot of more than £6m has yet to be claimed by one lucky ticket holder in South Wales.
National Lottery say the whopping £6,053,028 prize, drawn on Saturday, June 29, is currently the highest unclaimed amount in the UK.
Players are being urged to check and double-check their tickets for the chance to claim the huge cash windfall.
The winning Lotto numbers on that date were 7, 13, 25, 31, 34, 45 and the bonus ball was 4.
The lucky ticket-holder, who bought the ticket in the Rhondda Cynon Taff area, has until Boxing Day to claim their winnings.
But if no-one comes forward with the ticket before the deadline, then the prize money – plus the interest it has generated – will go to National Lottery’s good causes.
A National Lottery spokesman said: “We’re desperate to find this mystery jackpot ticket-holder and unite them with their winnings – this amazing prize could really make a huge difference to somebody’s life.
“We’re urging everyone who bought a ticket in this area to check their old tickets again or look anywhere a missing ticket could be hiding.
“Try checking in the pockets of clothing, in wallets, bags and down the back of the sofa – someone out there could literally be sitting on a fortune.
“We have the champagne on ice and our fingers crossed that the lucky winner comes forward to claim their win.”
To jog Lotto players’ memories, Blurred Lines by Robin Thicke topped the UK singles chart at the time, while Kanye West was at the top of the album chart with Yeezus.
Sports fans will recall a couple of major sporting events which took place on the same weekend as the Lotto draw. On June 29 itself, the British Irish Lions narrowly lost to Australia in a pulsating 16-15 second test.
Away from sport, locals may have taken a trip to the Wales Millennium Centre in Cardiff where the Faulty Towers The Dining Experience was being performed.
Rhondda Cynon Taff has had its fair share of Lottery winners in recent years, including Ferndale lorry drivers Terry Roberts, Mike Williams, Lance Gifford and Gerwyn Jones, who pocketed more than £1m each. The Valley Boys Syndicate landed a share of the Triple Rollover jackpot in the Lotto draw on Saturday, April 16, 2011.
Since The National Lottery launched in November 1994, £30bn has been raised through sales of lottery tickets.
Anyone who believes they have the winning ticket for any of the National Lottery draws within the 180-day deadline should call the National Lottery Line on 0845 910 0000.
