Hide-and-seek (sometimes known as hide-and-go-seek) is a popular children's game in which at least two players (usually at least three) conceal themselves in a set environment, to be found by one or more seekers. The game is played by one chosen player (designated as being "it") counting to a predetermined number with eyes closed while the other players hide. After reaching this number, the player who is "it" calls "Ready or not, here I come!" or "Coming, ready or not!" and then attempts to locate all concealed players. The game can end in one of several ways. The most common way of ending is the player chosen as "it" locates all players; the player found first is the loser and is chosen to be "it" in the next game. The player found last is the winner. Another common variation has the seeker counting at "home base"; the hiders can either remain hidden or they can come out of hiding to race to home base; once they touch it, they are "safe" and cannot be tagged. The game is an example of an oral tradition, as it is commonly passed by children. Variants Different versions of the game are played around the world, under a variety of names. One variant is called "Sardines", in which only one person hides and the others must find him or her, hiding with him / her when they do so. The hiding places become progressively more cramped, like sardines in a tin. The last person to find the hiding group is the loser, and becomes the hider for the next round. A. M. Burrage calls this version of the game "Smee" in his 1931 ghost story of the same name. In the Peanuts comic strip by Charles Schulz, a variation of Sardines called "Ha Ha Herman" is played, in which the seekers call out "ha ha', and the person hiding has to respond by saying "Herman". In some versions of the game, after the first hider is caught or if no other players can be found over a period of time, the seeker calls out a previously-agreed phrase (such as "Olly olly oxen free", "Come out, come out wherever you are" or "All in, All in, Everybody out there all in free") to signal the other hiders to return to base for the next round. the seeker must return to "home base" after finding the
