10 or more players, aged 5 and up, played indoors and outdoors.

Players form a long single-file line, each holding the waist of the player in front of him. The game begins with the first player in line, the leader taking the flock on a journey. Since the role of leaders is always the most difficult, the leader will always try to change places with the sleeper, the last player in line, and he may do so by catching the sleeper.

However, the sleeper does not want to give up his position and he tries to evade the leader. The leader must then be very tricky, to sneak up on the sleeper and catch him sleeping.

If the leader is successful, he becomes the sleeper and the next player in line becomes the leader. Then the game continues, with the leader always taking the flock on a little journey through a series of obstacles (under a table, around a tree etc...) before he tries to catch the sleeper.
