Lottery fever has spread across Europe as the Euromillions jackpot has reached a world record €150 million for tonight's draw.
If there is a single winner from tonight's draw, the winner would receive the money in a tax-free lump sum prize.
The biggest Euromillions jackpot prize to date was over €115 million, won last summer by Dolores McNamara from Limerick.
A National Lottery spokesman said 2,500 tickets were going through the system in Ireland each minute. "There's a huge interest right through the country. The big jackpot has got a lot more people into the draw,'' he said.
According to the National Lottery the biggest previous lottery prize was in the United States last October when the multi-state Powerball game had a jackpot of €277 million - but the prize was paid in a pre-tax lump sum of €134 million.
The National Lottery advised players to play early, to sign the back of their EuroMillions tickets and to keep them in a safe place.
"It would also be a good idea for syndicates to give each member a copy of the numbers played and to make sure each member is fully aware of the share they are entitled to in the event of a win," Lottery Director Dermot Griffin said.
