A "ryanmen" is two consecutive tiles waiting to complete either side of a sequence, such as {34}, {45}, {78}. Terminals can never be part of a ryanmen shape - {12} and {89} are not ryanmen. A ryanmen has twice the acceptance as any other type of basic wait. | A "[[ryanmen]]" is two consecutive tiles waiting to complete either side of a sequence, such as {34}, {45}, {78}.

Chanta can technically can use ryanmen, via {23} and {78}. However, it is only half as effective, as you only get chanta with 1/2 of the winning tiles (1 and 9, respectively). Therefore, since chanta cannot use ryanmen, it is slower to develop than a regular hand. Plus, in order to guarantee chanta in [[tenpai]], your hand must have a bad wait (<= 4 tiles left in the wall). | Chanta can technically can use ryanmen, via {23} and {78}.
