How Two Concealed Kongs (雙暗槓) works

A hand that includes two kongs, both of which were declared concealed rather than from a claimed tile.

Two of the four-of-a-kind sets must be concealed kongs, meaning all four tiles were drawn into the hand and declared without claiming a discard. The remaining sets and pair complete the hand normally. The kongs count as concealed pungs for the higher Three/Four Concealed Pungs fans, but Two Concealed Pungs itself is not added on top of this fan — the official example scores the kongs, their terminal/honor pungs and the win conditions only.

Good to know
  • An added (promoted) or claimed kong does not count toward the two.
  • The concealed kongs count toward Three or Four Concealed Pungs, but the 2-point Two Concealed Pungs is absorbed by this fan.
  • Each kong of terminals or honors still scores its Pung of Terminals or Honors.

Two Concealed Kongs (雙暗槓) — FAQ

What makes a kong concealed for this pattern?

All four tiles must be held and declared without claiming a discard; a kong formed by adding to an exposed pung or by claiming does not qualify.

Do these kongs also help with concealed-pung patterns?

Yes. Each concealed kong counts as a concealed pung, so two of them contribute toward concealed-pung fan as well.
