100
This is a game in which a number of players conceal themselves in the environment, to be found by one or more seekers. The game is played by one player (designated as being "it") counting to a predetermined number while the other players hide. After reaching the number, the player who is "it" tries to find the other players.
After the player designated as "it" finds another player, the found player must run to base, before s/he is tagged by "it." In some versions, after the first player is caught, it calls out "Ollie Ollie oxen free" (or "all outs, all in free" or many other variations) to signal the other hiders to return to base for the next round. In yet another version, when players are caught, they help the "it" seek out others.[2] The phrase "Ollie Ollie oxen free" may derive from the German "Alles, Alles auch so ein frei!" ("Everyone, everyone is also as free as this person I just tagged out!")
