What is a "freeroll"? A freeroll is a poker tournament that allows players to play for real money, with no buy-in. Freerolls are common in the world of online poker among texas holdem players. Many webmasters offer their site's loyal visitors free roll tournaments as an added bonus for being a frequent visitor of their site.
The prize pools vary anywhere from $50 to $10,000 based on how much money the poker room or webmasters are willing to put up for their freerolls. Freerolls are the poker rooms way of marketing themselves to individuals who normally wouldn't play online poker unless it was free.
Who usually plays in freerolls? Most of the time it is a bunch of "freeroll whores" who go from freeroll to freeroll trying to build up a bankroll.
Is there any strategy that helps you win free rolls? There could be. I would recommend either playing it safe until some of the idiots have been knocked out, or playing aggressively in order to knock some of the idiots out early on. Just watch out for the dumb ass that goes all in with a 3 5 off suit against your pocket aces. They usually flop trips or a straight and take your chips. This kind of play is inevitable in texas holdem freerolls. Someone always has somewhere else to be and decides to go all in with garbage. That's just the way it goes sometimes.
Be careful and play hard.
