The Powerball jackpot is now $1.3 billion, the game's fourth-largest prize. Most people still buy tickets in person, but lottery apps could change that as more states approve online purchases. The winner can choose a lump sum of $608.9 million or an annuity worth $1.3 billion, both of which are pretax estimates. The next drawing is Saturday at 10:59 p.m. ET.
