I've played in a lot of freerolls on a lot of sites... as a "free" (LOL) American who i still banned by our own idiot government from playing on the major
poker sites, freerolls is literally all I can do these days.
I recently joined CardsChat since I saw they run freerolls on the sites we "free" (LOL) Americans can still play on for
real money... and here's what I noticed by way of comparison... the CardsChat freerolls are quite a bit different from your normal
poker site freerolls. And I mean that in a GOOD way. When a freeroll is open to anyone on the poker site, those tournaments are very loose, and very crazy, with the expected "all-in" style of poker even during early levels. But CardsChat freerolls are not really like this at all. There is a lot more folding in early levels, much like a "normal" (non-freeroll) tournament... and it also seems to me that the CC freerolls are populated with much better, much more competent and experienced players than a regular freeroll. They are tougher to go deep in, and despite the turbo format,
they take a bit longer to reach the money. (which is my brief answer to the OP's post)
This is just my own opinions, and I've only been a member here for a few months... but I play poker to get better, and to challenge myself... so I'm not complaining with my words here! I'm very happy with CC and the freerolls, and happy with the player base that plays in them regularly.
Hope that helps. Again, just my opinions, yours may differ.
