Can't Stop is a great Parker Brothers board game. You can download an electronic version that allows you play against human and/or computer players. Rules for Can't Stop can be found at Dan Checkoway's site.
Dan programmed the original game (allowing only human players). I added the option of computer players, and also now allow keyboard input (in addition to mouse clicks).
My current computer player is pretty good. It makes good decisions based on the position of its own markers, but it doesn't take into account the other players markers yet.
The real fun begins when you decide that you want to write a computer player to challenge mine. You can download the current C++ code. See readme.html to see what you files you need to modify to create your player. My brother Brian and possibly a couple other people are going to participate. Send me email if you are interested.
