A Mahjong piece is a TILE used in the Chinese game of Mahjong. It is typically made of bone or bamboo and has a unique design on each side. The tiles are divided into three categories: Suits, Honors, and Bonus tiles. Suits are numbered from one to nine and consist of four copies of each number. Honors are divided into Winds and Dragons and consist of four copies of each type. Bonus tiles are divided into Flowers and Seasons and consist of only one copy of each type.
