Avoid this game
There is no skill to it, it just gets to the point where its impossible to proceed and then you fail, it isnt like tetris, or other good puzzle games where your skill will determine how long your game lasts.
On top of that there is an annoying system built in to encourage in app purchases so even if you pay for the game you feel like you didnt get a finished product. Awful all around,
