Shousangen

Conditions

• The hand must contain triplets (or quads) of two different dragons
• The pair must be the third dragon tile
• The remaining two melds can be anything
• Shousangen itself is worth 2 han, but since each dragon triplet is also a yakuhai (1 han each), the hand always includes at least 4 han total (2 for shousangen + 1 + 1 for the two dragon yakuhai)
• Worth 2 han regardless of whether the hand is open or closed

Strategy Tips

• If you start with pairs or triplets in two different dragons, aggressively pursue shousangen. Call pon on dragons when possible since the guaranteed 4 han minimum makes this a very strong hand even when open.
• Watch the discard piles carefully. If several of one dragon have been discarded, completing two dragon triplets becomes impossible, and you should abandon the shousangen plan early.
• Shousangen naturally requires holding many honor tiles, so it can combine with honitsu (half flush) if your remaining melds are from a single suit. This pushes the hand value even higher.
