Chinroutou 「清老頭」 is a yakuman scored when every tile is a terminal (1 or 9). In other words, no simples (2-8) or honors are allowed. For short, it can be referred to as chinro.

Tile pattern

Agari: or

Routouhai

Routouhai 「老頭牌」, or "terminals" in English, are the tiles numbered 1 or 9. They are called "terminals" because they are always the end of a sequence; a tile group such as 9-1-2 is not a valid sequence. The terminals are as follows:

Formation

For this yakuman, there are only six types of terminals available: two from each of the numbered suit (1 and 9). A standard winning hand is 4 melds and a pair, five out of the six types of terminals are needed to build the hand.

Since there are only six tile types available for this hand, it is impossible to form a chiitoitsu variation.

Viability

Aside from needing five out of the six terminal types, every tile group must be triplets (or kans). So, any attempt at this yakuman requires the proper number of terminals as well as the ability to collect triplets. More often than not, players must make tile calls in order to do so. Only a rare number of times can this yakuman be completed while closed. On the other hand, the yakuman is rendered impossible if enough terminals are discarded or made unavailable.

-For this yakuman, there are only six types of terminals available: two from each of the numbered suit (1 and 9).  Simply, no other tile type can be used for this yakuman.  Given the basic hand pattern of four melds and a pair, five out of the six types of terminals are needed to build this hand.  Since there are only six tile types available for this hand, it is impossible to form a [[chiitoitsu]] variation.
