It's twenty bucks a month. That gets you into a whole host of daily freerolls ranging from 25 bucks up to 200 (I think 200, maybe more, maybe less). They also have a monthly 40k freeroll and a weekly 7k.
Essentially you have to build up your points in point tourneys to play in the "token" tourneys. The "token" tourneys are basically satellites into the bigger freerolls where you can buy your entry with a red or blue token. Top prize for the big one is 10k.
I like the site and have already won enough this month to pay my membership (for the month of March I mean). The membership is still low so the overlay on most freerolls is excellent. Sometimes you start with top 9 paying and only 50 participants, though that depends on time of day or day of the week.
