Cool. The odds of winning where very good the first 7 weeks, there where only 500 or so entries. This week there are around 1500. Still good odds compared to other sites.
They are giving away 4 free credits when you sign up, then they charge $5 a credit after that. I have been playing for 6 weeks with free credits, you win credits for placing in top 2 as well, cool site...
