They're all based off the same company or whatever you want to call it but they all have a special freeroll in them. First off, they all have the $1,000 freeroll more than once a day so that's pretty cool. But then, Bet365 has a $5,000 freeroll every Saturday which is awesome cause only 6000 people can get in it and these freerolls go FAST. The blinds go up so fast in there people don't have time to screw around...you have to play hands in there which I really like. BetHoldem has a freeroll every Monday for football which I believe is a $2,000 freeroll and you can make a small bet on the team that you think is going to win and if they do(and you place in the freeroll) they quadruple whatever you won in the freeroll!! Highly suggested sites if you want to start off your BR with freerolls.
