Fully Concealed Hand (門清自摸)
A fully closed hand (no called melds) won by self-draw. Combines the concealment and self-draw bonuses.
How Fully Concealed Hand (門清自摸) works
A hand that is never exposed during play and is completed by self-draw, meaning no tiles were claimed from other players and the winning tile came from the wall.
To qualify, the player must take no chow, pung, or kong from a discard and must win by drawing the final tile rather than on someone's discard. It rewards keeping the entire hand secret from start to finish. The self-draw nature is built into the requirement, so it represents a richer winning condition than a plain self-draw on an exposed hand.
- •Claiming any tile from a discard during the hand permanently forfeits this pattern, even if later tiles are self-drawn.
- •Concealed kongs declared from your own drawn tiles are allowed and do not break concealment.
- •Because the win must be self-drawn, a concealed hand that goes out on someone else's discard does not qualify here.
Fully Concealed Hand (門清自摸) — FAQ
Can I declare a kong and still keep this pattern?
Yes, provided it is a concealed kong formed entirely from tiles you drew; an exposed kong claimed from a discard breaks concealment.
If my hand is fully concealed but I win on a discard, do I get this?
No. This pattern requires both full concealment and a self-drawn winning tile.
