Four Kongs (四槓)
Four declared kongs plus a pair. The kong-heaviest hand possible — exceedingly rare.
How Four Kongs (四槓) works
A hand whose four sets are all kongs (groups of four identical tiles), leaving only a pair to complete the fourteen-tile structure.
Each of the four melds is a kong, whether concealed or melded, drawn from any suits or honors. Declaring four kongs requires four separate kong declarations during play, each accompanied by a replacement tile from the wall, so the pattern is exceptionally rare. As the dominant fan in the hand, it absorbs lower kong-related and triplet-related values rather than scoring them all separately.
- •All four sets must be kongs; the remaining tiles form only the pair.
- •Subordinate kong and concealed-set fan are implied by this pattern rather than counted again.
- •Mixing concealed and melded kongs is allowed and does not change the core requirement.
Four Kongs (四槓) — FAQ
Do the kongs need to be the same suit?
No. The kongs may come from any combination of suits and honors; only that all four sets are kongs matters.
Can the kongs be a mix of concealed and exposed?
Yes. Any combination of concealed and melded kongs qualifies, as long as there are four of them.
