GAMES Both children and adults play many games, most of which have probably been introduced since the conquest. A favorite among these is a game known as _tak in kul_, in which a number of players stand in a row with their hands behind their backs while one, who holds a small pottery disk in his hand, stands behind the row, another standing in front. The one holding the disk places it in the hands of one of those in the line, who in turn passes it to his neighbor, so that it travels rapidly up and down the line. The player in front has to guess in whose hand the disk is at the moment of guessing. If he is right, the holder of the disk has to come in front while the one who guessed correctly joins the line. _Chac_ is a sort of "knucklebones," played with pottery disks, which are tossed from the palm to the back of the hand and back again; the one who drops fewest disks in a given number of double throws wins the game. The boys make little bows (_pohoche_) and arrows (_hul_) tipped with black wax, with which they play war and hunting games. A seesaw made from a small tree balanced on a stump is popular, as is also a sort of merry-go-round constructed from a cross of poles fixed on top of a stump by means of a wooden pin, which rotates freely. The children sit at the extreme ends of the poles and make the contrivance rotate by kicking against the ground vigorously at intervals as they go around.
