Dont use this app it is horrible. 0 out of 5 It gives a 30second add every two moves. You cant back out of the 30 second ads. I have played for 10 mins and had 30 mins of ads. I am not letting my children be exposed to this much advertising. At least put a few pop up ads which i could remove. Not 30 second adds. I cant get into a rythem with 30 second ads while i am trying to figure out moves.
