In a Mah Jongg set there are four pieces of each of these tiles, that is, there are four East Wind tiles, four South Wind tiles, four West Wind tiles and four North Wind tiles.
For scoring purposes the Wind tiles are known as the Simple Honour Tiles and this means that Wind tile suits you collect will be assigned higher score values.
For a Wind suit - you may collect Pungs, Kongs or a pair of identical wind tiles (the latter only for the purpose of going Mah Jongg) - Chows are not allowed.
