Players stand facing each other in a circle. Each player has one hand palm up, and the other palm down. Palm-up hands are placed on top of the adjacent palm-down hands. This may take some time to figure out. Do the best you can.
Palm-down hands try to hit palm-up hands before the palm-up hands are pulled away. If the palm-down hand misses, it becomes a palm-up hand. Attempting to follow these rules leads to a certain amount of mayhem. Which, of course, is the whole point.
