Ryanmen

Revision as of 13:06, 11 February 2014 by KyuuAA (talk | contribs)

Ryanmen 「両面」 is the most commonly occurring wait pattern in the game. Commonly referred as the "open wait", this pattern involves two consecutively numbered tiles, waiting on the "outside" number. For example, a 3-4 needs either a 2 or a 5 in order to form melds 2-3-4 or 3-4-5. By far, this is the most efficient wait pattern, as it uses just two tiles while waiting on a maximum of eight possible tiles.

Pattern

              Waiting for:   or  

Always, ryanmen wait for two tiles. In addition, two ryanmen patterns may combine to form a ryanmenten, which waits for 3 tiles instead of two.

Fu

Due to its relatively ease, the ryanmen pattern is not awarded any fu. The inability to gain fu based on ryanmen makes it an essential component to the yaku, pinfu.

Suji

     
     
     

Ryanmen is directly related to suji, or the mahjong "octaves". At any time, ryanmen waits on a pair based on the three "octaves" of: 1-4-7, 2-5-8, and 3-6-9.

              Waiting for:   or  

In this example, the consecutive 2-3 needs either of the two waiting tiles in order to complete the sequence. The 1 and 4 is included in the 1-4-7 octave.
