SuperEnalotto is a lottery that has been played in Italy since 3 December 1997. 'Enalotto' is a well-known Italian lottery which has existed since 1950's. In 1997, SISAL modified the 'Enalotto' lottery to create SuperEnalotto.
Until June 30, 2009 the six main winning numbers were taken from the first number drawn in Lottomatica's regional Lotto draws for the cities of Bari, Florence, Milan, Naples, Palermo & Rome (used in that order). The Venice draw was used as a "Jolly" number. If the first number of a city had been used before, then the second of the city's draw was used - and so on. In this system there was a small probability that the numbers of two cities could be the same - in which case there would have been duplicate numbers and it would have been impossible to win the jackpot.
Draws take place on Tuesdays, Thursdays and Saturdays at 8:00 PM. The jackpots won are among the largest in the world, and the odds of winning one of the lowest in the world.
After more than 8 months of rollovers, the largest single-ticket jackpot up to date is worth €177.7 million ($248 million). This was won by a syndicate of 70 winners on October 30, 2010.
€147.8 million (US$205 million) was the 2nd largest single-ticket jackpot won on 22 August 2009 in Bagnone (Toscana). Only one winner so he's the biggest prize winner.
