My implementation of Coloretto by Michael Schacht is now available. The intelligence of the 'bot' opponents is not quite there yet (still working on that part) but the game is playable and I thought I'd open it up and start getting a little feedback while I'm at it. Feel free to comment on this story if you have any issues and/or questions.

You can also come to the marquand.net directly and click on the blue Coloretto Topic Link (in the upper left hand corner). Enjoy.
