A single ticket purchased in New Jersey has won Powerball's jackpot of $315.3 million.
That amount is reduced to $183.2 million if the winner (or winners) chooses a lump sum instead of spreading it out over 30 years.
Hitting the jackpot with co-workers would bring additional challenges.
"If you go in on an office pool, make sure it's done right," said Jason Kurland, an attorney with Certilman Balin Adler & Hyman, a law firm in East Meadow, New York.
"People don't treat it like a transaction [potentially] worth hundreds of millions of dollars, but that's essentially what it is," said Kurland, who specializes in helping lottery winners.
For starters, it would be much harder to follow the expert advice to remain anonymous in states where winners are permitted to shield their identity from the public. If you win in a pool, there's already potential leakers of your business from the get-go.
