Really, the best game for a phone currently on the market.
Set up similarly to Mafia Wars mixed with Magic: The Gathering.
I've spent tons of actual money on this free game. Still addicted and still need referrals!
I get a benefit for your referral and so do you. Also, the game is amazing, try it out.
My referral code is grr93787. Referral code is entered at the end of the tutorial.
Let me know if you have any questions.
