Step 1: Create your track in the snow, as illustrated above (in chicken feet, for extreme clarity). This is essentially a giant circle with an X in it, created by shuffling your feet as you scoot in the aforementioned shape.
Step 2: Players, take your positions. Max. 4. Each equidistant from each other at the ends of the X shape.
Step 3: Decide who is 'IT'.
Step 4: Explain that each player has to stay on the OX Track. You are allowed to move back and forth, across and back. There is NO PASSING. In order to get in front of, or behind another player use one or more of the legs of the X shortcut. Whomever is tagged becomes 'IT' and so on.
Step 5: GO!
Step 6: Laugh hysterically and become outrageously winded.
