Ing Equipment consists of purpose built clocks, stones and boards. Hundreds have been donated by The Ing Foundation to the American Go Association and are commonly used at the US Go Congress as well as other tournaments throughout the United States. Ing rules require that both players begin with exactly 180 stones. The custom containers for Ing stones allow the players to quickly verify that the required number of stones are present.
Ing equipment can be purchased from Yutopian.
