After lvl 60 you'll either need a credit card or to quit. I won't pay for any of these games. They penalise you for a period of time, where you can't play, if you won't pay or invite friends. That's crazy! I made it to lvl 60 twice, after deleting the game the 1st time, and starting over. This game is for high scoring Mahjong players and people who pay money to buy their scores. I won't cheat and buy my way to the top. When something no longer makes you feel good - walk away.
