3 players are holding hands.
The players can stand with front outward or with back outward.
One of the players carries a overall blouse. The fourth player is the catcher.

The catcher must try to touch the player with the overall blouse and the 3 players must try to make it difficult or impossible by turning in such a way, that the player with the overall blouse always is covered by the 2 other players.
Of course the catcher must not move directly into the covering players and reach over them to touch.
