Popular 'Enalotto' is a well-known Italian lottery which has existed since 1950's. In 1997, SISAL moodified 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. Since July 1, 2009 the numbers have been drawn independently of the Lottomatica draws. There is one single draw for the six winning numbers and the "Jolly" number and a second independent draw for the "SuperStar" number. Game SuperEnalotto is a lottery that has been played in Italy since 3 December 1997. Draws take place on Tuesdays, Thursdays and Saturdays at 8:20 PM. The jackpots won are among the largest in the world, and the odds of winning the worst in the world.
