tac tix




TacTix was invented by Piet Hein, a Danish poet who was also well known for dabbling in mathematics and science. The game is played in its misere form because the strategies listed above render the non-misere variant trivial. According to Martin Gardner, the board size most commonly played at the time he authored his article is 6x6, because it "is small enough to keep the game from being long and tiresome, yet complex enough to make for an exciting, unpredictable game." (Gardner 160)

The Board

The board is an NxN grid of squares.

The Pieces

The pieces are usually circles but they can be anything as long as you can pick it off the board. N^2 pieces are needed to play a game.


To move: The player removes as many pieces lying adjacently in a row or column as he or she wants. At least one piece must be removed.

To win: To force the opponent to remove the last piece from the board.

Set up the board so every square on the board is covered by a piece. The first player may then take as many pieces as they want off the board, provided that they are adjacent to each other and all lie in the same row or column. Players alternate doing this until the last piece is removed, in which case a winner is determined.
