Thunderball Lotto bet slips have been available for bettors to purchase since a few days before its first draw. The date of the Thunderball launch was 12th June 1999 and this UK draw which was initially based on the US Powerball model has remained a popular one with those who like to bet on lottery results ever since. If you buy Thunderball Lotto bet slips the maximum win is a set figure of £500,000, although this hasn’t always been the case. For just over a decade those who bet on this particular draw were aiming at a jackpot figure of £250,000. Currently if you decide to purchase Thunderball Lotto bet slips you will need to select 5 numbers from 1 to 39, then add a further selection of just one number from between 1 and 14, the latter selection being the Thunderball. Bettors can land the jackpot if they correctly select all 5 numbers that arrive form the first drum and also manage to choose which number comes out from the Thunderball drum. The Thunderball itself also adds to the amount those betting on this draw win if they land a secondary prize. Should you opt to purchase Thunderball bets then you should be aware this is a thrice weekly draw and the days for your notebook are Wednesday, Friday and Saturday.
