Simply the Best

Ever since this was a web app, I knew that Connect4 Touch (its first name if I recall correctly) would have a great potential as a real app. Now that it is one, theres much more to love about it. This is the by far the best electronic version of Connect Four EVER. If you dont want to shell out the money (which I dont see why not, its worth every cent), you could get the free, ad-supported version.
