Powerball begins

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.[citation needed] 타이산게임

Through 2008, Powerball drawings usually were held at Screenscape Studios in West Des Moines, Iowa. The drawings' host was longtime Iowa radio personality Mike Pace, who had hosted MUSL drawings since Lotto America began in 1988. In 1996, Powerball went "on the road" for the first time, holding five remote drawings at the Summer Olympics in Atlanta. A few weeks later, Georgia became the only jurisdiction to leave Powerball (Maine, which joined MUSL in 1990, left when Powerball began). In August 1996, Georgia joined the then-new The Big Game, then the other major U.S. lottery group. It planned to sell tickets for both games for the rest of 1996; but within days Georgia was removed from MUSL, not to return until the 2010 cross-sell expansion.

On November 2, 1997, the annuity was changed from 20 to 25 yearly payments; the cash option was added.[8] The annuity comprises 30 graduated payments increasing 5% annually.

In 1998, Florida was given permission by its government to participate in a multi-state game. It was set to offer Powerball; but in early 1999, new governor Jeb Bush prevented Florida from joining since he believed Powerball would hurt the existing Florida Lottery games. In 2008, Governor Charlie Crist finally allowed Florida to join MUSL, on Jan 4, 2009.

On March 7, 2001, an optional multiplier (called Power Play) was added, allowing players to multiply non-jackpot winnings by up to five by paying an extra $1 per game. A wheel was introduced to select the Power Play multiplier for each drawing (the next year, the 1x was removed from the Power Play wheel.)

2009: Florida became host to drawings

With the start of Powerball sales in Florida on January 4, 2009 (with its first drawing on January 7), the matrices changed to 5/59 + 1/39 (adding four white ball numbers and dropping three red balls). This changed the jackpot probability from 1:146 million to 1:195 million; the overall probability became 1:35.

Based on statistical projections, the average jackpot win increased from $95 million to $141 million. Over 3.5 million additional prizes were expected to be won yearly due to the change in probability. The starting jackpot increased to $20 million, with minimum rollovers of $5 million. The jackpot contribution increased from 30.3% to 32.5% of total sales. The Power Play option was modified; second prize, usually $200,000, was given an automatic 5x multiplier, making the 5+0 prize $1 million cash. The bonus second prize if the jackpot exceeded its previous record by $25 million, triggered only twice, was eliminated with the 2012 format change.
