Best time killing game ever! The level of concentration to do these is at that perfect point, where you can play it and still pay attention in class. Also it helps you multiply small numbers.
Not working I've had this game for years but on my galaxy note 5 the screen won't fit to mine so some of the pieces to make the square are off page. I can't get past level one because of it. I would love to enjoy this game again but not until the bug is fixed.
This is my most favorite game ever!
