TacTix is a two-player game, where the players take turns removing game pieces from the board. The goal is to force the other player (the computer) to remove the last game piece.
On each turn, you may remove one or more pieces from either a single row or a single column. The pieces must be on adjacent squares. You may remove from 1 to 4 pieces on your turn.
To make a move, use the mouse to select the counters you want to remove from the board, then press the Move button.
The computer will make its move automatically after yours. To have the computer move first, press the Move button without selecting any counters.
