BigDuckGo

BigDuckGo started as a pretty simple idea and fun project... What will happen if I combine the classic elements of Tic-Tac-Toe with the Strategy and Gameplay of Battleships? - The answer to this idea is BigDuckGo. As the game begins you are able to choose between three levels of difficulty: 1. Easy peasy, 2. Medium rare and 3. Mission Impossible. The matchfield features 4x4 caskets and under each of them is either an X or an O. So your job is to find the 4-in a row X before the AI finds the 4-in a row O...

BigDuckGo itself is fully written in C++ and is available on Linux and Windows.
