One player is chosen to be It. He calls out the name of another player, to whom he at once gives chase. A third player at any point in the chase may run between the one who is It and the one whom he is chasing, whereupon this third player becomes the object of the chase instead of the second. At any time a fourth player may run between this player and the chaser, diverting the chase to himself, and so on indefinitely. In other words, whenever a player crosses between the one who is It and the one being chased, the latter is at once relieved of the chase and ceases to be a fugitive. Whenever the chaser tags a player, that player becomes It. Considerable sport may be added to the game by the free players trying to impede the chaser and so help the runner,–getting in the way of the former without crossing between the two, or any other hindering tactics.
