TacTix is a classic Nim-based strategy game invented by Danish polymath Piet Hein. Played on a 5×5 grid filled with pieces, players take turns removing any number of contiguous pieces from the same row or column. In this Misere variant, the player who is forced to take the last piece loses. The game requires careful calculation and strategic foresight, as every removal shapes the remaining possibilities for both players.
