Paengi-Chigi (kor:팽이치기) is a traditional Korean game enjoyed by both the both young and the old and is played mainly in the winter. This game involves a top and a stick with a long string. These spin tops are wound up with twine and then let go. Players must keep hitting the spinning top with the string tuck with the stick to make it rotate for a long time. One of the places to experience a couple of these traditional games is at Namsongol Hanok Village. (Wikipedia).
