===2009: Move to Florida===
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.

The conditions for Florida joining Powerball included a move of the live drawings from Iowa to [[Universal Studios Florida|Universal Studios]] in [[Orlando, Florida|Orlando]].{{citation needed|date=February 2019}} The three hosts rotating announcing duties from Universal Studios were Tracy Wiu, Elizabeth Hart and Scott Adams (MUSL headquarters remained in Iowa, where its other draws are held). The wheel that was used to determine the Power Play multiplier was retired when the drawings moved to Florida; a [[Random number generation|random number generator]] (RNG) was used until the 2012 format change.

[[Arkansas Scholarship Lottery|Arkansas]] became the 33rd MUSL member on October 31, 2009,<ref>{{cite web |url=http://arkansasmatters.com/content/news/Lottery_Fulltext?cid=258812 |access-date=2016-02-09 |df=mdy-all |title=KARK }} {{dead link|date=July 2018|bot=medic}}{{cbignore|bot=medic}}</ref> the last to join before the 2010 cross-sell expansion. The [[Ohio Lottery]] added Powerball on April 16, 2010, it joined [[Mega Millions]] (along with New York) years earlier, when ''The Big Game'' added ''Mega Millions'' to its name.
