Therefore, for pure tile acceptance, a lone 4/5/6 >= lone 3/7 > lone 2/8 > lone 1/9 > lone guest winds. This is before considering mechanics like furiten and dora. With [[red fives]] in play, 4/6 become stronger than 3/7 due to being able to create ryanmen with a red five.

[[Yakuhai]] are a special case. Because they can be [[pon]]'d to instantly gain a yaku and a group, they are more valuable when both these conditions are met: 1. the hand would not have any yaku if opened, and 2. the hand does not have an obvious "4 groups + 1 pair" yet. In an average starting hand, they are more valuable than 1/9 but less important than 2/8.
