Ion: free puzzle app game for iphone, ipad

Ion is a free puzzle app game that's kind of interesting. The object is to stay alive by lining up colored discs from any corner to the center. You do this by rotating discs.

After each rotation, more colored balls are randomly generated. You lose when the board fills up.

I played this for about 30 minutes and did not lose.

Ion is an interesting puzzle game, but it's too easy.  Let me know how you like it.
