You are the Elf and Santa is himself.
Try to get your three elfs in a row (either horizontally, vertically, or diagonally)
before Santa does. Begin playing by clicking on a box. Then it's Santa's turn.
 Keep on playing until one of you gets three in a row.
You can let Santa go first if you like by click on the button that says "Santa Goes First."

Watch out -- Santa's pretty good, so don't get discouraged.

Have fun!
