Update 3pm: National Lottery says the winner of 88 million euro in last nights euromillions has made contact with them.

However for now they have not revealed where the winner is based.

Update 11.45: The National Lottery's first piece of advice to Ireland's newest Euromillions winner is to sign the back of their ticket.

Somewhere in the country there is a ticket worth €88.5m after last night's draw.

It beat the odds of around 140 million to one to take the jackpot on its own.

National Lottery CEO Dermot Griffin says his office is ready to help: “Well the first thing we would tell them to do is to sign the back of the ticket and make contact with the national lottery.

“We will guide them through the process from there.

“It will take until next week before all of the money is transfered, from the other countries into Ireland, so we will be paying out the jackpot hopefully sometime next week.”

People around the country today are making shopping lists for what they'd do if they were the lucky winners.

But after the immediate celebrations die down, Peter Brown from the Irish Institute of Financial Trading says the winners need to take steps to protect themselves: “Get it safe in Government risk and then it is safe and now we take six months to educate ourselves because now what happens to these people a lot of the time is the run into the wrong financial advisor and they end up in all kinds of ponzi schemes and awful stuff and they don't understand what is going, they can't tell the difference between a good advisor and a bad advisor.”

Latest: If you won last night's EuroMillions jackpot, you've beaten odds of 140 million to one.

If you're as poor today as yesterday, mathematician Eamonn Toland said there are come common ways people might not be making the most of their chances.

"If you pick numbers in a pattern - across the top and down the side of the grid for example, or in the 1-2-3-4-5 pattern - a lot of other people will do that every week.

"You could win the jackpot - but you'll end up sharing it with a lot of other people," he said.
