In the game of tag, one player is designated as "it" and must chase the other players to touch them. Once a player is tagged, they become "it" and the game continues. The objective is to avoid being tagged while running and dodging. Hide and seek is another popular children's game where one player closes their eyes and counts to a predetermined number while the others hide. After counting, the seeker tries to find all the hidden players. The first person found becomes the next seeker, and the game repeats. Both games encourage physical activity and social interaction.
