"Duck, Duck, Goose" is a popular children's game played in a circle. Players sit on the ground while one person, known as the "picker," walks around the outside of the circle, tapping each player on the head and saying "duck." When the picker chooses someone by saying "goose," that person must chase the picker around the circle. If the picker reaches the empty spot in the circle before being tagged, they sit down, and the "goose" becomes the new picker. The game encourages physical activity, social interaction, and fun among children, making it a favorite in playgrounds and schools.
