TacTix
TacTix is a two-player strategy game invented by Piet Hein, a poet well known for dabbling in math and science, best known for his game Hex. TacTix is essentially a two-dimension version of Nim; players alternate moves, removing one or more tokens in a single row or column until the last one is removed. At the time of its founding, TacTix was played on a 6x6 board, but is now usually played on a 4x4 board. The game can be played in its misere and non-misere forms. The strategies listed here render the non-misere gameplay trivial. The game is often used as a programming exercise, and many versions are available on the web as Java applets. (Wikipedia).
