World Poker Forums

I usually play real life poker with friends and we do it like this, everyone buys in 5€ to join, everyone gets about 100 chips to play. Eventually some will start loosing as the blinds double every 15/30 minutes. In the end the winner takes everyone's 5 € but the second place's 5€, so if we are 5 players the total amount would be 25€ first place gets 20, second gets 5€.Now the questions, does it work like this in pokerstars torneys aswell? If i buy in, say, 100bucks (real money) will i get a number of playchips to play the torney till i loose everything, or must i bet with my own money?Regarding play money torneys, is there any advantage joining those? I read in the pokerstars site that sometimes they launch freeroll games that allows people to win real money without buying in, how can that be ?Big thanks in advance
