Very addictive. Until you get up higher in the levels... Challenging. However, the levels have gotten so hard that I have stopped playing this game and started others. It took 65 tries to beat level 1519. It stops being fun and I don't even want to take the time to get my daily bonus points. I really did enjoy it before it became almost impossible to beat. AND, They need to TURN OFF THE **** FAST FORWARD! Are you kidding me!!!??? It is not a game you are going to KEEP PLAYING.
