Big Three Dragons (大三元)

What is Big Three Dragons?

Big Three Dragons (大三元), pronounced daai saam yuen, is an 8-faan Hong Kong Mahjong winning hand requiring pungs (or kongs) of all three dragon tiles — Red Dragon (紅中), Green Dragon (發財), and White Dragon (白板). It is one of the iconic high-faan patterns in HK Mahjong and pays 64 base units, making it among the most rewarding non-limit hands.

How to score Big Three Dragons

The hand must contain three of the four melds as dragon pungs or kongs: one each of 紅中, 發財, and 白板. The fourth meld and the pair can be any valid combination — chows, pungs, or any tile suit including more honors.

Because each dragon has only four tiles in the deck (12 dragon tiles total), assembling three dragon pungs typically requires a combination of self-drawn and claimed tiles, often across multiple turns. The hand becomes increasingly visible as dragons accumulate — once two are exposed, opponents will defensively avoid discarding the third.

Example hand

Faan value: 8

Big Three Dragons is worth 8 faan, paying 64 base units. It supersedes and absorbs the individual 1-faan dragon pungs (Red Dragon, Green Dragon, White Dragon) — those are not counted separately when Big Three Dragons applies.

Common combinations

Big Three Dragons stacks with structural and win-action patterns:

• Big Three Dragons + All Triplets (對對胡) — 8 + 3 = 11 faan, when the fourth meld is also a pung. Pays 192 base units.
• Big Three Dragons + Mixed Flush (混一色) — 8 + 3 = 11 faan. The fourth meld and pair use one numbered suit; the dragons satisfy the honor allowance.
• Big Three Dragons + Concealed Hand (門前清) — 8 + 1 = 9 faan, when no dragon pung was claimed.
• Big Three Dragons + Self-Pick (自摸) — 8 + 1 = 9 faan.

Big Three Dragons upgrades Small Three Dragons (小三元, 5 faan) — the two are mutually exclusive. If a hand has two dragon pungs plus a dragon pair, it scores Small Three Dragons; completing the third dragon pung promotes it to Big Three Dragons and overrides the lower score.

Strategic note

Big Three Dragons is one of the most “telegraphed” hands in HK Mahjong. By the time a player has exposed two dragon pungs through claims, the table knows what’s coming and will hold dragon tiles defensively rather than discard them. Many Big Three Dragons attempts succeed only via concealed pungs (self-drawn) for at least one of the three — making the Concealed Hand stack disproportionately likely on this pattern.
