Drive a stake into the ground. At the top of the stake there is a revolving ring. Tie 4 long strings to the ring. 4 players take these strings by the ends and stretch them out. It's "a merry-go-round". Between the stretched strings there stand some other players. The players who have the strings in their hands run clockwise. The players who stand between the strings stand counter-clockwise (while running they jump over the stretched strings). The players who touch the strings while running are out of the game. Then the players switch the roles.
