dunno if this has been posted or not, all it really is, is you pay a small fee to enter into a match with random people then depending on the match you've picked depends on how much you win if you do, no its not a scam or anything along those lines, thing is its only for games like css which sucks but yeah my friend made $100 in one day just from playing css for a while
