Coconut fern is by far the best freeware Connect 4 game out there. Kudos to the developer.

This is a perfect little game! I loved C.F. as a kid, and this gives a beautifully faithful look & feel, from the look of the pieces "sliding" down, to their sound, to the coloring. A.I. is good, and it has option to play against another human, so it's the perfect little game to pull out when you and a friend are stuck somewhere. People really like it, even PDA haters. It's so charming! Well done.
