All Green

What Is All Green

All Green is an iconic 88-fan hand in Chinese Mahjong, composed exclusively of the Bam ranks 2, 3, 4, 6, 8 and Green Dragon. Forming your four melds and one pair entirely within this restricted tile set poses a formidable challenge. Opponents often try to block or hoard Green Dragons and crucial Bam ranks once they sense your plan, but a triumphant “All Green” declaration produces one of the most spectacular and high-scoring outcomes in Mahjong.

The Tile Pattern of All Green

All Green requires:

• 2 Bams, 3 Bams, 4 Bams, 6 Bams, 8 Bams
• Green Dragon

Example:

• Pung of 2 B (2 B, 2 B, 2 B)
• Chow of 2–3–4 B (2 B, 3 B, 4 B)
• Pung of 6 B (6 B, 6 B, 6 B)
• Pung of Green Dragon
• Pair of 8 B (8 B, 8 B)

All tiles are within the green set (2, 3, 4, 6, 8 of Bams and Green Dragon).

Fan Value of All Green

Under Chinese rules, All Green is awarded 88 fan, the highest fan tier in the standard scoring table (alongside a few other ultra-rare hands like Big Four Winds, Big Three Dragons, etc.). Because 88 fan is far beyond the typical 8-fan minimum, completing “All Green” almost guarantees a decisive win in that round.

Strategies and Considerations of All Green

Check for “Green” Tiles in Your Opening Hand: If you begin with multiple copies of 2 B, 3 B, 4 B, 6 B, 8 B, or Green Dragons, you might consider “All Green.”

Discard Other Ranks/Colors: Swiftly discard any Characters, Circles, Bamboo ranks outside {2, 3, 4, 6, 8}, or other honor tiles to focus your draws on the “green” subset.

Calling Pungs: If you see a needed Bamboo rank or Green Dragon discarded, you can call “pung” to speed completion. Each call exposes part of your plan.

Possibility of Chows: You can theoretically form 2–3–4 in Bamboos, but because 5 B and 7 B are disallowed, sequences involving them are impossible. So the only standard chow pattern from these ranks is 2–3–4.

Fully Concealed: If you self-draw everything, you may gain extra fan for a self-drawn final tile, though overshadowed by the main 88 fan. Staying concealed too long might be risky if an opponent is close to winning.

High Visibility: Once you start discarding all non-green tiles, opponents may guess you are attempting a specialized hand—possibly “All Green.” They might hold back key Bamboo ranks or Green Dragons to block you.

Tile Counting: Only 2, 3, 4, 6, 8 in Bamboos and Green Dragon are allowed. Keep track of how many copies have appeared. If too many critical tiles are used up, consider pivoting to a simpler pattern (though it’s difficult once you’ve committed to discarding everything else).

Narrow Tile Pool: You rely on a small set of Bamboo ranks plus Green Dragon. This can make the hand difficult to complete if opponents realize your aim. If successful, 88 fan is the pinnacle. It can singlehandedly decide a round or match.
