Tag games are popular outdoor activities where players chase each other in an attempt to "tag" or touch another player. The game typically starts with one player designated as "it," who must try to catch the other players. Once a player is tagged, they may become "it," or the game may have specific rules about how tagging works. These games can vary in style and rules, with variations like Freeze Tag, where tagged players must freeze until another player unfreezes them, or Shadow Tag, where players must stay within a certain distance of the person who is "it." Tag games promote physical activity and social interaction among participants.
