Concealed Kong and Melded Kong (明暗槓)
One concealed kong and one melded kong in the same hand — worth 6 points (Green Book #57 note).
How Concealed Kong and Melded Kong (明暗槓) works
Holding one concealed kong and one melded (exposed) kong in the same hand — worth 6 points.
The hand declares two kongs, one formed entirely from self-drawn tiles and one completed with a claimed tile. The rulebook prices this mixed pair at 6 points (a note under Two Melded Kongs: "One Melded Kong and one Concealed Kong are 6 points"), replacing the individual Concealed Kong and Melded Kong fans. The concealed kong still counts as a concealed pung toward Two/Three/Four Concealed Pungs.
- •Exactly one kong is concealed and one is melded.
- •Worth 6 points; the single-kong fans are absorbed, not added.
- •The concealed kong also counts as a concealed pung for pung-based fans.
Concealed Kong and Melded Kong (明暗槓) — FAQ
Do the two kongs also score their individual kong fans?
No. The 6-point combined value replaces the 2-point Concealed Kong and 1-point Melded Kong.
Does the concealed kong break a concealed hand?
A concealed kong keeps the hand concealed; the melded kong in this combination is what opens it.
