Line of 4

Price: Free
Line of 4 is a take on the popular game Connect-4.  If you’ve never played, the goal of the game is to get four markers of your color in a row before your opponent does – its essentially a two dimensional version of Tic Tac Toe.  Line of 4 has three difficulty options, with the hardest one presenting a rel challenge.  Additionally, you can play against another person locally, or over the internet.  For online play, you must create a free account or you can link it with your Facebook account.  A nice bonus feature is the ability to choose the color of your pieces.  Line of 4 does everything you would want from a Connect-4 app, and should be downloaded by all fans of the game.
