The basic rules are the same as tag.
One person is “Mr. Yuck” and the others run. When you get tagged you may cover your “wound” with one of your hands. When you get tagged a second time, you may cover your “wound with your other hand. The third time you get tagged, you are out.
We did the same thing except that whatever part you were tagged on went numb (i.e.-if your arm was tagged, you couldn’t use it.) If you ran out of forearms, shoulders, and legs, you had to lie there, until someone tagged you. Then you were out of the game.
