Tap back or tap hand is a game which is described in both the Foxfire 6 book as well as the Frank C. Brown Collection of NC Folklore. It’s very similar-or actually the same thing as-the game which is often played in lower grades of elementary school called duck duck goose.
Any number of people can play the game-the more the merrier. Everyone joins hands in a large circle. One person is chosen to be ‘it’-they walk around the outside of the cirlce until they tap someone on the back/hand/head. Then the it person-runs quickly around the circle-the person who is tapped runs after them. Whoever wins the race back to the spot the person left gets to be part of the circle-leaving the loser to be the tapper.
One variation of the game described in the Foxfire 6 book, says if the one tapped beats the person who was ‘it’ back to their spot in the circle-the tapper has to go into the center of the circle-which was sometimes called the soup pot. Once in the soup pot-you can only get out if the person who is ‘it’ decides to reach in and tap you.
