The 2015 changes extended the main ball pool to 69 balls, adding another ten numbers. However, at the same time, the Powerball pool decreased from 35 to 26. This means that although the overall odds of winning the jackpot have increased to 1 in 292 million, the overall odds of winning any prize have decreased to 1 in 24.87. The first draw incorporating the changes took place on October 7th and also saw an increase in the tier three prize (matching 4+1) climb to $50,000.


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.
Due to falling sales of Hot Lotto (whose final drawing was October 28, 2017), a new version of Lotto America became available on November 12, 2017; its first drawing was November 15, 2017. Lotto America is available wherever Hot Lotto was offered at the time of its final drawing (except New Hampshire.) Lotto America is drawn on Wednesday and Saturday nights after 11 p.m. ET/10 p.m. CT. For each $1 play, bettors choose five numbers from 1 through 52, and a "star ball" numbered from 1 through 10, or ask for terminal-generated numbers. For an additional $1 per play, the bettor can add the "All-Star Bonus" option, which multiplies non-jackpot prizes by 2, 3, 4, or 5.[1][2][3][4] The minimum Lotto America jackpot is $2 million; however, the game's initial jackpot was $15 million; the 13 members chose to augment the jackpot with funds from Hot Lotto, whose final jackpot was not won.
The US Powerball is a standard lottery draw game based and operated from the golden State of California. The US Powerball has been making millionaires and multi-millionaires since its first drawing way back in 1992. With over 25 years of experience in the lottery industry, the Powerball, along with many other State lotteries, has broken through the final glass ceiling and transformed itself from an interstate lottery into a truly international lottery of global reach.
