OK, this is going to be a stupid question (expecting a stupid answer or two), but what is a Freeroll? I've heard this all over on a couple of the gaming sites, but really have no idea what they are.

It's a tournament with no buy-in cost, ie-free. often with a cash prize but can also be a satalite for entry into another, bigger tourney.

there is no entry free, you can usually win at least something from them, sites that i know of that have them are pokerstars,pokerpages,ultimatebet,fulltilt,checknraisepoker,fairpoker,
pokerchamps, and that is all I can think of right now.

absolutepoker has freerolls running pretty much all day.. definately check that out if you want freerolls.
