Hide-and-seek is a popular children's game in which one person hides and the others try to find them. It is often played outdoors, but can also be played indoors. The goal of the game is for the hider to remain hidden until all of the seekers have found them. The game is usually played with two teams, with one team designated as the hiders and the other as the seekers. The hiders must find a hiding spot and remain there until they are found by the seekers. The seekers must then search for the hiders until they are found.
