C4 was made by me (Scott McClymont) as part of my 4th year BSc Computer Science dissertation in late 2005 - early 2006 at Heriot-Watt University in Edinburgh, Scotland. This internet-based version was created alongside a version for handheld devices such as mobile phones. I also investigated the game in detail in order to gain a greater understanding and appreciation of how the game works. I also wanted to see what has made it stand the test of time and remain popular throughout the many iterations of its life back to when Captain Cook first played it in the 1700's.

The Connect 4 tutorials use techniques first documented by Victor Allis in 1988.
