Four Concealed Pungs (四暗刻)
Four concealed (self-drawn) pungs plus a pair. Tsumo only — calling pon breaks the concealment.
How Four Concealed Pungs (四暗刻) works
A hand of four triplets (or kongs) all formed concealed, plus a pair, with no set having been claimed from a discard.
Every one of the four pungs must be made from tiles drawn by the player, not completed by claiming an opponent's discard. The hand is necessarily all-triplet, and concealment of each set is the defining constraint. It is a limit-level hand closely related to the broader all-triplets pattern but with the stricter concealed requirement.
- •Claiming a discard to complete the fourth pung typically drops the hand to a lesser all-triplets pattern rather than this one.
- •Winning on a discard for the final pung is a common edge case some tables treat as breaking the fourth concealment.
- •Concealed kongs declared from drawn tiles count toward the four sets.
Four Concealed Pungs (四暗刻) — FAQ
Can any of the pungs be melded from a discard?
No. All four triplets must be concealed; an exposed pung from a discard disqualifies this limit hand.
What if I win on a discard that completes my last pung?
Many tables rule that the discard-completed set is not fully concealed, so the hand counts as ordinary all-triplets instead; this is a known table-rule variation.
