SphereChain is a puzzle game in which you are presented with a number of spheres containing 4 numbers each (top, bottom, left and right). The objective is to get rid of all the spheres by matching their numbers with neighboring spheres. You can tap on the spheres to rotate the numbers clockwise. Matching 2 or more spheres creates a "chain", similar to dominoes, which can be removed at any time by tapping a button. If there are open spaces, you can drag spheres around without jumping over existing ones and a new sphere will appear every 10 seconds.
