Computix is a edutainment game.
The board is made of 8x8 squares.
At the beginning, the 64 values are placed randomly on the board. You play horizontally, the computer plays vertically. The cursor is symbolized by a red circle.
When you click on a square in the cursor's line, its value is added to your score (or substracted if its value is negative), the square becomes unavailable and the cursor goes on it. Then the computer plays in the cursor's column.
The game ends when no more squares are available.
