Project Invincible on Windows

Project Invincible is a free, portable, open source and cross-platform chess game. Challenge a friend to a 3D chess battle or test your skills against a computer opponent. If the AI is too strong for you, just make it weaker with settings. After all, it's not a shame to lose to full strength of Project Invincible. :)
