Nearly 800-million dollars is up for grabs in America's two largest lotteries. With no grand prize winner in last night’s Powerball drawing, the jackpot jumps to $306-million ahead of the next drawing on Saturday. The cash option on that works out to just shy of 148-million bucks. As for the even more massive Mega Millions jackpot, no one struck it rich on Tuesday so tomorrow night's drawing will be worth an estimated $457-million.
