#REDIRECT [[List of yaku]]
'''Yaku''' (役) are specific hand patterns or conditions needed in order to score a hand.  In a sense, they are synonymous to "poker hands".  Yet, unlike poker hands, yaku are worth specific "[[scoring|han values]]"; and various yaku may be combined together into one hand.  basic mahjong knowledge involves learning the yaku, but it is not expected of new players to know them.
