If you played Euromillions on June 21 and failed to check the results of the draw, you may well be sitting on half a million euro.

And with just 11 days left to claim your winnings, it's time to start start pulling the house apart so you don't let €500,000 slip through your fingers.

According to reports, the winning Quick Pick ticket was purchased in the Ninth Lock Service Station in Clondalkin, Dublin 22, and came up trumps in that evening's EuroMillions Plus draw.

If you're currently lurching around the house in a desperate bid to unearth the pile of lotto tickets you know exists somewhere in your home, these are the numbers you should keep in mind – 3, 23, 24, 32 and 46.

Oh, and if you do happen to stumble across the winning ticket, you will need to present yourself at the National Lottery Headquarters on Abbey Street in Dublin by Monday September 19.

Ladies? It's go-time.
