Daisangen

Daisangen

Daisangen (大三元, だいさんげん) is a yakuman where you have triplets of all three dragon tiles: White (haku), Green (hatsu), and Red (chun). The name translates to “big three dragons” and represents one of the most visually striking yakuman hands. Worth maximum points regardless of whether the hand is open or closed.

Detailed Explanation

Requirements

To achieve daisangen, you must have:

• Triplet of White (haku): Three White dragon tiles
• Triplet of Green (hatsu): Three Green dragon tiles
• Triplet of Red (chun): Three Red dragon tiles
• Any fourth meld and pair: The remaining meld and pair can be anything

The three dragon triplets can be open (pon) or concealed (ankou)—the yakuman value remains maximum regardless.

Open vs. Closed

Unlike many yaku, daisangen maintains full yakuman value whether open or closed. This makes it attractive for aggressive play—you can call pon on dragon discards without penalty, speeding up completion significantly.

Strategy: Many players building toward daisangen will call pon on any of the three dragons to secure those triplets quickly. Since 12 specific tiles (three each of four dragons including duplicates) are needed, calling melds dramatically improves chances of completion.

Rarity and Recognition

Daisangen is moderately rare but more achievable than some yakuman because:

• Dragons are common: Dragon tiles often appear in early discards, making pon calls available
• Visible target: Once you have two dragon triplets, opponents can see you’re one triplet away from daisangen and will avoid discarding the third dragon type
• No suit requirements: Unlike chinitsu-based yakuman, daisangen doesn’t care about suits—only dragons matter

The visual impact of three dragon triplets makes daisangen instantly recognizable and dramatic when revealed.

Strategic Considerations

Telegraph Risk: Calling pon on two dragon types immediately signals daisangen to opponents. Experienced players will hoard the third dragon type rather than discard it, forcing you to self-draw those tiles.

Yakuhai Foundation: Even two dragon triplets provide 2 han from yakuhai. If daisangen doesn’t develop, you still have a decent scoring hand with multiple yakuhai plus any additional yaku.

Defensive Response: When an opponent has two dragon triplets exposed, absolutely avoid discarding the third dragon type. Hold those tiles even if it slows your own hand—dealing into daisangen is devastating.

Usage Example

Early in the hand, you draw two White dragons and call pon when the third is discarded. Later, you draw three Green dragons and call pon again. You now have two dragon triplets exposed. Opponents recognize the daisangen threat and stop discarding Red dragons. Over several turns, you self-draw all three Red dragons, completing the third triplet concealed. Your final hand: White-White-White (open), Green-Green-Green (open), Red-Red-Red (concealed), plus any meld and pair. You win and declare daisangen (yakuman). All opponents pay maximum points—8,000 base points (32,000 total for non-dealer) or 12,000 base points (48,000 total for dealer).
