Half a million pounds is the top prize for those who take the plunge and decide to play Thunderball. That figure has not always been available for jackpot winners, as when the draw launched on the 12th June 1999 it was £250,000. The doubling of the maximum win took place in 2010 when 3 significant changes were made to this popular draw. Should you play Thunderball the current format is you must select 5 balls from a total of 39 for the main part of the draw then 1 ball from 14 for the Thunderball section of the game. When the game was originally conceived the draw contained 5 fewer balls. When the draw originally launched those who decided to play Thunderball could only participate in 2 games a week, this changed in 2010 when a third draw was added. The days to check your tickets now are Wednesday, Friday and Saturday, there was no Friday draw for over 10 years. If you play Thunderball then the jackpot will be your aim and to achieve this you must land all 5 balls from the initial draw and also the Thunderball from the second drum. If you play Thunderball and don’t win the jackpot then all is far from lost as 1 in every 29 tickets purchased will ensure a prize goes to its owner.
