The Taiwanese variation of marbles is played on a 1.5 to 2 meter diameter pit, which comprises a circle of flat bare earth; preferably the hard-packed gray clay that is commonly found in the floodplains throughout the island. Within the pit are five shallow holes or depressions. Four are at the points of the compass near the perimeter of the pit with the fifth directly in the center. The depressions are no more than 10 centimeters in diameter and 3 centimeters deep.
