In the OfficeThe workplace is one of the most popular places to run an NCAA Tournament pool. But remember -- betting money on the NCAA Tournament isn't -- strictly speaking -- legal in most places, and your HR department may forbid such things.
Another concern -- there may be a fairly-well established NCAA pool in your workplace already. You don't want to step on the toes of the office bookie. (I know this from experience... my wife has been the "Paulie Walnuts" of her office for years.)
Friends and FamilyBecause most March Madness pools are Internet-based these days (more on that in a second), it's easy to get a big group of friends and family together for a pool via e-mail. This does make collecting money a bit tricker... more on that in a moment.
On the WebMost of the big sports sites will allow you to join some sort of "open" group and compete for cash or prizes.
Once you've got your players, the next step is to decide where you'll host the game.
