Bamboos, Circles and Wan
In a Mah Jongg Game Set there are four pieces of each of the tiles that make up these suits, as described below. For scoring purposes the 1's and 9's of the Bamboo, Circles and Wan suits are known as major tiles and combinations that you collect of these will be assigned higher score values. The 2's - 8's of the Bamboo, Circles and Wan suits are known as minor tiles and consequently score lower value points.
For each of these suits you may collect Chows, Pungs, Kongs or a pair of identical tiles (the latter only for the purpose of going Mah Jongg).
