The twice-weekly lottery is played in France, Belgium, Spain, Portugal, Ireland, Luxembourg, Austria, Switzerland and the UK. 40 million tickets were sold for Tuesday's rollover jackpot.
The winner, who is still unknown, has sixty days to contact lottery bosses to claim the massive prize. The winning sum could buy four tonnes of gold or 20,000 Renault Clios.
No more information was available about where the new multi-millionaire bought his or her ticket. Security on tickets was tightened after an incident in 2007 when a tobacconist was almost able to get away with stealing €35 million from one of his customers.
The unscrupulous tobacconist substituted a losing ticket for a winning one when a customer who had won €35 million came in to check whether he had won. The tobacconist then gave the winning ticket to a friend and the two planned to share the bounty. They were only found out when discreet questioning by the lottery organizers revealed that the false 'winner' wasn't aware that the same numbers had been played in the same establishment for several years.
As a result, ticket holders can now check whether they have won on independent machines.
Tuesday's win isn't quite the biggest ever Euromillions jackpot, which was won by a Scottish couple who bagged €185 million in July.
