When a [[kan|kantsu]] is declared with exactly one tile left in the live wall, that tile, called the [[haitei|haiteihai]], is appended to the dead wall and never drawn. This rule makes the replacement tile the haiteihai, so winning with that tile scores both [[rinshan kaihou]] (winning after kan) and [[haitei raoyue]] (winning with the last tile).

Score a mangan upon exhaustive draw for having discarding only yaochuuhai during the entire hand, with none of the yaochuuhai having been called by other players, and without having called any tiles oneself. If this is allowed, there are additional rules decisions necessary: Does it count as a win, or merely as replacement of the noten penalty? Are concealed kantsu allowed?
