When it was launched in 1992 Powerball became the first game to use two drums. Using two drums to draw numbers from offers more manipulation by simultaneously allowing high jackpot odds, numerous prize levels and low overall odds of winning (as explained later, a ticket can win by matching only one number). The two-drum concept was suggested by Steve Caputo of the Oregon Lottery. The two-drum concept has since been used by The Big Game (now Mega Millions) in the US, Australia's Powerball, Thunderball in the UK, Eurojackpot and EuroMillions (unlike most two-drum games, Euromillions selects two numbers called "Lucky Stars" from the 2nd drum; jackpot winners must make a total of seven matches).[citation needed]

The structure of the draw is one which regular lottery players will be very familiar with; players must pick 5 regular numbers from a pool with a total of 69 numbers and in addition to these regular number picks, you also choose one bonus ball (known as the Powerball) from a pool of 26. These two pools of numbers are mutually exclusive and remain completely separate throughout the drawing procedure. In order to jackpot the US Powerball, you need to match all 5 regular numbers and the Powerball. Do this and you are instant Powerball millionaire – it’s as simple as that!
