Powerball is the biggest jackpot game in the US. Your numbers can be saved for next drawing by touch entering your numbers. Edit/Delete your saved numbers and the app instantly circles the matching numbers against the winning numbers--you can match them against one of the past winning numbers as well.

"Match against winning numbers menu" option, on the My Numbers bar, calculates the sum of the prize amount of all the matching numbers and let you know how much money you have won.

The Winning Numbers page shows all the winning numbers from January 1, 2015 to the most current one and the winning numbers are updated automatically. But you can always update the winning numbers manually with "Check for winning number update" option in the Last Winning Numbers bar's menu.

Enjoy and good luck!
