Check Mahjong No Jan-Ryu for the original article. 

*Translation of the original article start below*

For the last opf this 7 tile series, let’s look at the pattern when using all 4 tiles of one specific tile. Be aware, that among the 7 tile examples, these 3 patterns are on the difficult side, and are rare case scenarios. It would be better to perfect the pervious 16 patterns, and practice the following 3 patterns if you have extra time.

7 Tiles (17/19)
Waiting on 3 Tile Types, 9 Tiles in Total
4P has 3 Tiles, 3P has 2 Tiles and 6P has 4 Tiles remaining

If you see the 5 Pin as a Jan-Tou (2 Tiles), it will be a 4 Pin Kan-Chan wait. If you see the 5 Pin as an Anko (3 Tiles), it will be a 3・6 Pin Riyan-Men wait.

Different example for the same shape of wait.

6,4,7 wait and 5,4,7 wait.

Maximum amount of tiles here are 9 tiles.

▼ And next we have…

7 Tiles (18/19)
Waiting on 4 Tile Types, 13 Tiles in Total
2P has 4 Tiles, 5P has 3 Tiles, 3P has 2 Tiles and 6P has 4 Tiles remaining

If ypu see the 4 Pin as your Jan-Tou (2 Tiles), it will be a 2・5 Pin Riyan-Men wait. If you see the 4 Pin as an Anko (3 Tiles), it will be a 3・6 Pin Riyan-Men wait. (Note that the 3 Pin can also be seen as a Tanki wait).

You can remember this shape as striding over the 4 tiles you have.

Different example for the same shape of wait.
6,9,5,8 wait and 3,6,4,7 wait.

Maximum amount of tiles that can be waited here is 13 and is pretty good.

▼ And lastly…

7 Tiles (19/19)
Waiting on 4 Tile Types, 13 Tiles in Total
2P has 4 Tiles, 5P has 3 Tiles, 3P has 3 Tiles and 6P has 3 Tiles remaining

If you see the 4 Pin as the Jan-Tou (2 Tiles), it will be a 2・5 Pin Riyan-Men wait. If you see the 4 Pin as an Anko (3 Tiles) it will be a 3・6 Pin No-Be-Tan wait.

Same as the previous shape, this one can be remembered as striding over the 4 of the same tiles that you have in your hand.

Different example for the same shape of wait.
6,9,5,8 wait and 1,4,2,5 wait.

Maximum amount of tiles that can be waited here is also the most at 13 tiles.

Regardless of the shape, the key is to either see the 4 set tiles as “3 tiles as an Anko” or “2 tiles as a Jan-Tou”.

These are all 19 patterns and we have gone over all of them! Next time, let’s just go through all 19 patterns one last time.
