Determine a circular area. You may want to rope it off to keep kids inside or lay down a hose in a circle and be prepared to shout "out-of-bounds!" to the "zombie". Remove any obstacles inside the circle. You can play this game indoors or outdoors. This game follows the classic rules of Marco Polo. The zombie wears the mask with the blindfold and hands. Meanwhile, everyone has to stay within the circle while he/she wanders around with his arms reaching out like a zombie. When the "zombie" groans, all the players must groan back and extend their arms. This is how the zombie closes in on his/her victims. When a player gets tagged, she becomes the next "zombie" and gets to wear the mask.
