Powerball is an American lottery operated by the Multi-State Lottery Association (MUSL), a consortium of lottery commissions in 29 states, the District of Columbia, and the U.S. Virgin Islands. MUSL is licensed as the monopoly provider of multistate lotteries in these jurisdictions.

Powerball's predecessor began in 1988[2] as Lotto*America; the game, and name, were officially changed to Powerball on April 19, 1992. Powerball was the brainchild of Ed Stanek of the Iowa State Lottery Commission. The matrix has been changed periodically.

On March 4, 2001, an optional multiplier wheel (called "PowerPlay") was added. On November 2, 1997, the annuity period was changed from 20 to 25 years, and the cash option was added. The annuity currently consists of 30 graduated payments (increasing annually) over a period of 29 years.

Powerball is drawn Wednesdays and Saturdays.

The most recent announcement of a nine-figure Powerball jackpot winner ($100 million or higher annuity value) was for a ticket bought in Westover, West Virginia, at a video lottery establishment known as "Paula's", which was the sole winner of the March 15, 2008 drawing, and which was worth approximately $276.3 million (annuity value; the winner(s), who have yet to be officially identified, can choose the cash option of $136.34 million instead). Among notable nine-figure wins prior to this was on a ticket that was purchased in Richmond, Indiana; that community had also produced the then-U.S. record $295.7 million (annuity) winning ticket for Powerball (July 29, 1998.

The MUSL games Hot Lotto and even Wild Card 2 are played the same as Powerball, albeit with smaller jackpots, and in only some of the MUSL jurisdictions, although Hot Lotto is scattered in mostly northern states.

How to Play Powerball
Powerball is a lotto game which is a combined large jackpot game and a cash game. Every Wednesday and Saturday night at 10:59 p.m. Eastern Time, we draw five white balls out of a drum with 55 balls and one red ball out of a drum with 42 red balls.
Players win by matching one of the 9 Ways to Win. The jackpot (won by matching all five white balls in any order and the red PowerBall) is either an annuitized prize paid out over 29 years (30 payments) or a lump sum payment. If the winner chooses the annuity, the annual payment will be increased each year by the percentage set out in the Powerball game rules.
You no longer have to select the payment option at the time of purchase. The tax law has changed to give you up to 60 days until after you claim the prize to decide whether you want cash or the annuity option. The second prize (won by matching five white balls in any order) is $200,000 paid in cash. Any time you match the red PowerBall, you win. The overall odds of winning a prize in the game are better than 1 in 37.
Power Play is a special feature that allows a winner to multiply the original prize amount. Powerball players can multiply their Powerball prizes by 2,3,4 or 5 times (does not include the jackpot). A player must choose the Power Play option when they buy their Powerball ticket, and then the ticket must match one of the non-jackpot prizes before the multiplier takes effect.

Powerball is played in 29 States, Washington D.C. and the US Virgin Islands. Play Powerball, It's America's Game!
