Small Three Dragons (小三元): How to Score This 5-Faan Hand in Hong Kong Mahjong
Small Three Dragons (小三元, pronounced siu saam yuen in Cantonese) sits in a sweet spot that many Hong Kong Mahjong players never quite appreciate. It is not the ceiling-busting limit of Great Dragons (大三元), but it delivers a solid 5 faan from a structure that is genuinely achievable at a real mahjong table. Two dragon pungs, one dragon pair, and two free sets to fill in: that is all it takes.
If you have ever held pungs of two different dragon tiles and wondered whether to push for the third, this guide answers exactly that question.
What Is Small Three Dragons?
Small Three Dragons (小三元) requires three components involving dragon tiles:
- A pung (or kong) of one dragon type
- A pung (or kong) of a second dragon type
- A pair of the third dragon type
The “small” in the name refers to that final dragon appearing as a pair rather than a full pung. Compared to Great Dragons (大三元), which requires pungs of all three dragon types and earns the limit, Small Three Dragons is the more attainable version of the same theme.
Your remaining two sets can be any valid combination: chows, pungs, or kongs in any suit or with any honor tiles. You just need those three dragon-related groups, one more set, and you are done.
How Much Is Small Three Dragons Worth?
Small Three Dragons is worth 5 faan in standard Hong Kong Mahjong. Here is how the scoring breaks down:
| Component | Faan |
|---|---|
| Pung of first dragon | 1 |
| Pung of second dragon | 1 |
| Small Three Dragons combination bonus | 3 |
| Total | 5 |
The pair of the third dragon does not score on its own. In Hong Kong Mahjong, a pair generally contributes nothing to the faan count unless the hand type specifically values pairs. What earns the faan here is the combination: two dragon pungs plus a matching dragon pair triggers the 3-faan bonus that takes the total to 5.
Five faan is a strong result. In most payment tables, a 5-faan hand earns considerably more than a 3-faan hand. If your table uses a doubling structure, the gap between a low-scoring hand and 5 faan is substantial. For a full overview of how faan translates to payment, see the Complete Faan Guide.
A Sample Small Three Dragons Hand
Here is one example of a valid Small Three Dragons hand:
- Pung of 中 (Red Dragon)
- Pung of 發 (Green Dragon)
- Pair of 白 (White Dragon)
- Chow of 3-4-5 Bamboo
- Pung of 9-Characters
In this hand, 中 and 發 are the pungs, 白 supplies the pair, and the bamboo chow plus characters pung complete the four sets. The bamboo chow and characters pung score nothing extra here, but they are valid sets that round out the structure.
The dragon pair (白 in this case) does not have to be declared openly. Because it is just a pair, it stays in your hand until you win. This is one of the appealing features of the hand: only two groups need to be shown on the table as called pungs, and the rest of the hand, including the dragon pair, remains concealed until you reveal your winning tiles.
Small Three Dragons vs Great Dragons
The most natural comparison is to the full version of the hand:
| Hand | Dragon sets required | Faan |
|---|---|---|
| Small Three Dragons (小三元) | Two pungs, one pair | 5 |
| Great Dragons (大三元) | Three pungs | 8 |
The difference is a single dragon pung. Convert the pair of 白 into a third pung and the hand jumps 3 faan and becomes a limit hand. That sounds simple in theory and is difficult in practice. Once your two dragon pungs are showing on the table, every opponent knows exactly what you are building and will stop discarding dragons. Getting that third pung by calling becomes nearly impossible.
If you find yourself with two dragon pungs and a pair of the third dragon, ask two questions. First, how many copies of your third dragon have already been discarded? If one or two have been played out, there are still one or two left to draw. Second, how many turns are left in the wall? A thin wall makes a self-drawn upgrade unlikely.
In most real sessions, the safe play is to stay content with Small Three Dragons. Five faan is excellent. Chasing 8 faan while opponents actively guard against you often ends in no win at all. For a deeper look at the full Great Dragons structure and upgrade strategy, see the Great Dragons section of the limit hands guide.
Building the Hand in Practice
Start With a Strong Dragon Draw
The most common path into Small Three Dragons begins with noticing that your opening hand contains two pairs of different dragon types. Say you are dealt two 中 and two 白. Call a pung on the first 中 and the first 白 discarded by any opponent and you are halfway there. Now you just need a pair of 發 and two valid sets, and you are done.
Keep the Free Sets Simple
With two melds reserved for the dragon pungs, you have two free sets to assemble. Keep them simple. A chow in any single suit is easy to build. A pair of any wind or another honor tile can serve as your final pair if you draw into it. Avoid spreading across multiple suits, as that forces you to hold tiles you cannot use while you wait on dragon draws.
Use the Concealed Pair to Your Advantage
Because the dragon pair stays in your hand, opponents watching your table see only two dragon pungs and two other called sets. They know you are playing toward dragons, but they may not realize your pair of 白 is already locked in. If copies of that third dragon have been discarding freely early in the round, opponents may not realize how close you actually are to winning. That partial concealment is a genuine strategic edge.
Deciding Whether to Push for All Triplets
If both your free sets become pungs as well, your hand also qualifies for All Triplets (對對和). That adds 3 faan on top of the 5 from Small Three Dragons, pushing the total to 8 faan and hitting the limit. This combination comes together most naturally when your starting hand is heavy with pairs, making pung calls likely on multiple fronts. See the All Triplets guide for how to angle toward an all-pung structure from the start.
Defending Against Small Three Dragons
Once an opponent calls two dragon pungs in the same round, treat Small Three Dragons as a near certainty and adjust your discards. The key question is which dragon tiles are still live. If two pungs are showing and you hold a copy of the third dragon in your hand, do not discard it. It completes either the pair or a potential upgrade to a third pung.
Beyond dragon guarding, focus on not completing the opponent’s free sets. If they appear to be building toward a chow in bamboo, avoid discarding bamboo tiles that fill that gap. Standard defensive play applies here: when in doubt, discard the safest tile rather than the most convenient one for your own hand.
Scoring Small Three Dragons With TileBuddy
Small Three Dragons involves two individual dragon pungs (1 faan each) plus the 3-faan combination bonus, and TileBuddy calculates all three components together in one step. Enter each pung and the winning pair during score entry and the hand total appears immediately, along with any additional bonuses such as flower tiles or self-draw.
Because 5 faan falls below the limit in standard tables, other bonuses do add to the payout here. A self-drawn Small Three Dragons hand with two flower bonuses scores 7 faan total, one step below the limit. That additional faan is worth real money at the table, and TileBuddy makes sure none of it gets missed.
Small Three Dragons (小三元) is one of the most satisfying hands to build in Hong Kong Mahjong: specific enough to feel intentional, attainable enough to land in real games, and worth enough to shift the balance of a session. Next time you pick up two dragon pairs in your opening hand, you know exactly what to aim for. Download TileBuddy free on the App Store and let it handle every faan calculation the moment your tiles hit the table.
