Joining the office Powerball pool isn't always a smart gamble.
Pooling resources with a few co-workers can be an enticing prospect, especially now that the jackpot has ballooned to $700 million. The drawing is Wednesday at 10:59 p.m. EDT.
Generally, it's better to buy your own tickets, said "Lottery Lawyer" Jason Kurland, a partner with Certilman Balin Adler & Hyman in East Meadow, New York.
"I strongly dislike Powerball office lottery pools," he told CNBC.
The Multi-State Lottery Association puts the chance of walking away with the grand prize at 1 in 292.2 million for a single ticket (see infographic below), and buying a few more doesn't move the needle much.
"If you're going to take those crazy odds, you're better off doing it on your own so you don't have to split it," Kurland said.
