Start with these ideas
- Each qualifying Red, Green or White Dragon group contributes 1 faan, regardless of seat or round.
- The house example has a Red Dragon Pung and Concealed Hand: 2 faan, below the default minimum.
Reference values below follow the Hong Kong Mahjong Association (HKMA) rules. Worked calculator examples use our browser game’s house rules; check the differences before comparing results.
What is a dragon Pung?
Three identical Red, Green or White Dragons make a Pung. A legally declared Kong uses four identical tiles and retains the same dragon-group bonus. Open and concealed groups both qualify.
The three dragon types are different tiles: Red–Green–White is not a Chow and cannot be treated as one set.
One faan per group, without double-counting
HKMA and our house rules both award 1 per qualifying dragon group. Unlike winds, dragons do not need to match a seat or round. A pair alone earns no dragon-Pung bonus.
For Little Three Dragons, HKMA adds the two dragon bonuses to its 3-faan pattern; our game already includes them in 5. For Big Three Dragons, HKMA uses 5 + 3, while our game settles an inclusive 8-faan limit.
A dragon pair is not a scoring Pung
Two Red Dragons may be a legal pair, but they are not a 1-faan dragon group. In our game, a dragon pair also prevents All Chows; HKMA’s All Chows pair rule differs, so check that rule separately.
Try 2 faan, then 3
The example has a Red Dragon Pung and three Chows, all concealed. On a discard it scores Dragon Pung 1 + Concealed Hand 1 = 2 under house rules. Switching to self-draw adds 1 and reaches the default 3-faan minimum.

A hand to try
Win: discard · Seat: East · Round: East · Minimum: 3. Declared melds and special draw context are loaded with the hand.
With the saved win method, seat wind and round wind, this example is expected to score 2 final faan under sc_hk13_v1_2. The calculator also shows every contributing pattern and whether the hand reaches the selected minimum.

A few things to know
Does a dragon Kong score more than a dragon Pung?
Not for the dragon-group item in our game: either is 1. A Kong-replacement win can earn a separate event bonus only when that replacement actually completes the hand.
