The record prize, if the ticket was bought by a single person rather than a syndicate, would be the world's biggest lottery win, Sky News said. The winner has not yet come forward.
EuroMillions is a pan-European lottery, launched in 2004. Initially only the United Kingdom, France and Spain were involved, but lotteries from Austria, Belgium, Ireland, Luxembourg, Portugal and Switzerland joined the draw in October 2007.
Draws are held every Friday night, and take place in Paris. A standard EuroMillions ticket costs 2 euros per line played. All prizes, including the jackpot, are tax exempt, except in Switzerland, and are paid in a lump sum.
Russia launched its Gosloto, the first state lottery since the Soviet era, in 2008 to help raise funds for the 2014 Winter Olympics in the Black Sea resort Sochi and to promote sport and a healthy lifestyle.
A man from Kolpino, near St. Petersburg, won 100 million rubles, or nearly $3 million, in March this year.
