Power Play, when it began in 2001, was drawn with a special wheel. In 2006 and 2007, MUSL replaced one of the 5× spaces on the Power Play wheel with a 10×. During each month-long promotion, MUSL guaranteed that there would be at least one drawing with a 10× multiplier. The promotion returned in 2008; the ball landed in the 10× space twice. After being absent in 2009, the 10× multiplier returned in May 2010 (after the Power Play drawing was changed to RNG.) The promotion was extended for the only time, as the 10× multiplier was not drawn until June 12. The second prize 5× guarantee continued; the 10× applied to all non-jackpot prizes, as in previous promotions.
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!
