Using Dots and Boxes with a group or class

Frequently asked questions
Who goes first?
Team A (or you) go first. Play alternates unless a box is completed.
How does the computer play?
It takes boxes when it can, avoids giving boxes away, and otherwise picks at random.
What is the best strategy?
Avoid drawing the third side of any box until you have to. Then try to give away as few boxes as possible.
