KEY POINTS
  • Powerball's jackpot is an estimated $457 million for Saturday night's drawing.
  • For Mega Millions' next drawing, set for Friday, the top prize is $405 million.
  • The chance of winning in either game is tiny: 1 in 302 million for Mega Millions and 1 in 292 million for Powerball.

With Mega Millions and Powerball jackpots both topping $400 million, there are likely a lot of players daydreaming about how they'd spend such a windfall.

They also may want to think about what to do as a winner before the money actually reaches them. That is, there would be some big decisions to make before they even think about heading to lottery headquarters to claim the prize.
