Ryanmen itself appears in around ~50% of winning hands, which is common, but not even close to guaranteed. Hands that do not use ryanmen, like [[toitoi]] and [[chiitoitsu]], are immune to suji. | ||
As mentioned above, the middle tiles (4,5,6) have two suji intervals to account for. For example, a 4 has two suji in 1-4 and 4-7. A discarded 1 does not make 4 much safer. In order for 4 to be a "full" suji, both 1 and 7 have to be safe. | |||
Not all suji are equally safe. This is because some tiles can be targeted by [[kanchan]] (24) or [[penchan]] (12) waits. | Not all suji are equally safe. This is because some tiles can be targeted by [[kanchan]] (24) or [[penchan]] (12) waits. | ||
