Sanmenchan 「三面張」 is a class of wait patterns for three-sided waits. The most common involves a combination of two ryanmen (open wait). In fact, this is the default form. This pattern utilizes a string of five consecutive numbered tiles in the hand. The exact middle tile of this string is one of the waiting tiles, while the other two hand off the edge of the string. Hands can wait on three kinds of tiles using other forms. Some of them take names of their own, while others do not.

Default tile pattern

Waiting for:

Fu

Just like ryanmen, this tile pattern does not reward any fu.

Strategy

Sanmenchan is a powerful wait due to the large number of waiting tiles: 11 maximum possible, using any of 3-tile types. That number cannot be 12, due to one waiting tile (the middle number) already present in the hand. The waiting pattern is limited, however, to one of the three numbered suits. With suji, the waiting pattern involves one of the three mahjong intervals.
