Hide-and-seek or hide-and-go-seek is a popular children's game in which any number of players conceal themselves in the environment, to be found by one or more seekers. The game is played by one player chosen (designated as being "it") closing their eyes and counting to a predetermined number while the additional players hide. After reaching this number, the player who's "it" calls, "Ready or not, here I come!" and then attempts to locate all concealed players.

The game can end in one of several ways. In the most common variation of the game, the player chosen as "it" locates all players as the players aren't allowed to move; the player found last is the winner and is chosen to be "it" in the next game. An Additional 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're "safe" and can't be tagged. But if the seeker tags another player before reaching home base, that person becomes "it."

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 derivative in game is called "Sardines", in which only one person hides and the others must find them, hiding with them 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. A. M. Burrage calls this version of the game "Smee" in his 1931 ghost storey of the same name.

In a few versions of the game, after the first player is caught or if not any additional players can be found over a period of time, "it" calls out a pre-agreed phrase (such as "Olly olly oxen free", or "All in, All in, Everybody out there all in free") to signal the additional hiders to return to base for the next round. In another version, when players are caught they help the "it" seek out others.

In one variant, once all hiders have been located, the game then becomes a game of tag where the "it" chases after all the additional players and the first person tagged becomes the "it".

In another, the hiders who're found help the "it" track down the remaining hiders, but the first person to be found becomes the next "it."

In Australia, the game is often called "44 Homes." The hiders hide until they're spotted by the seeker, who chants, "Forty, Forty, I see you" (sometimes shortened to "Forty, forty, see you"). Once spotted, the hider must run to "home base" (where the "it" was counting while the additional players hid) and touch it before she or he's "tipped" (tagged, or touched) by the seeker. If tagged, that hider becomes the new "it."

In India, hide-and-seek is played differently - if any of the 'hiders' touch the seeker and says 'Dhappa', then the seeker has to count again. Notwithstanding if the seeker sees the hider before they manage to touch him/her and say dhappa, then that hider will be 'it' the next round, unless a few additional hider manages to 'Dhappa' the seeker without being seen.But now, instead of doing Dhappa on the "IT"s body, hiders can do dhappa where the "it" counts. The "it" is simply called as "Dianer" (daa-ee-nuh-rr); and the dianers takes a dian.(count)

In Brazil and Russia, hide-and-seek has an additional step. The "it" starts counting with eyes closed and facing the wall while everyone hides. Once the "it" finds someone, they must race to the spot where the "it" was originally counting and facing the wall and whoever touches that spot first, wins the game. This is additionally at times played by additional countries.
