Daisangen 「大三元」 is a standard yakuman. This involves the collection of all three tile groups of the sangenpai (dragon tiles). It is one of the three yakuman gosanke 「役満御三家」, or "the three big families of yakuman".

Note: This hand is also winnable with , but this hand would be shousangen instead.

Formation

As the name implies, this yakuman depends on all three sangenpai (dragons).

Sekinin barai

The rule of 'sekinin barai applies to daisangen in the form of yakuman pao. This occurs when a player seeking to develop this yakuman already had made open calls (pon) with two out of the three possible dragon types; and then the same player has taken the opportunity to call on the third dragon type. The player who discarded the third type then becomes liable for that play, where an seemingly obvious threat to a yakuman had become an apparent and actual threat of a yakuman.
