Dots and boxes

How to play
You and the computer take turns to place a line between to adjacent dots trying to form a box (by joining 4 dots with lines).
When you make a box, a blue square will appear inside it. When the computer makes a box, a yellow square will appear inside it.
The one who makes a box must take another turn.
The one who makes the most boxes by the time all dots are connected wins.
The game will determine at random whether you or the computer places the first line.
To place a line, move the mouse cursor to the place between two unconnected dots. When a faint line appears, click on the mouse to make the line permanent.
