This is a ripoff. It's fun in the beginning but it became money consuming. I recently experienced an 'unexpected error' yet money is still deducted without any credits. To add insult the game kept putting me into this 'tournament of champions' every week involuntarily. Talk about siphoning your money out. I decided this was the last straw and decided to uninstall the game. Unless you decide to give your money, it's better to save it elsewhere.
