I had this game about 4 years ago but couldn't remember why I uninstalled it. Now I know. Despite what they say it ISN'T about what strategy you use it's about the algorithum they've used for the pieces dropping. A cash cow for the developers. You struggle with a particular game, leave the game, and when you come back later miraculously you pass the game that you were struggling with. Uninstalled. WONT be installing again.
