All Green

What is All Green in Japanese Mahjong

All Green is a yakuman yaku that requires the player to form a hand entirely consisting of green tiles, which include the 2, 3, 4, 6 and 8 of Sou as well as the Green Dragon tile. The hand must be made up of four sets (either triplets or quads) and a pair, and it cannot contain any non-green tiles. All Green is extremely rare and difficult to complete, making it one of the most prestigious hands in Riichi Mahjong. The hand is a yakuman, meaning it offers the maximum possible points and is highly regarded in the game. Achieving this hand requires both luck and patience.

How to Achieve All Green？

All Green Tiles: The hand must be made up entirely of green tiles, which are:

• Sou Suit: The 2, 3, 4, 6, 8 of Sou are considered green tiles. The 2, 3, 4, 6 and 8 of Sou are often referred to as "green tiles" because they are colored in shades of green.
• Dragon Tiles: Only the Green Dragon tile is used. The Green Dragon tile is crucial for completing the hand as one of the sets or the pair.

Four Sets and a Pair: Like most hands, All Green requires the player to have four sets (either triplets or quads) and one pair. These sets must all be made up of green tiles.

• Triplets (Pung): Three identical green tiles (e.g., three 2 of Bamboo tiles, three Green Dragon tiles).
• Quads (Kong): Four identical green tiles (e.g., four 2 of Sou tiles, four Green Dragon tiles).
• Pair: Two identical green tiles, which can be from any of the green tiles used in the hand.

Yakuman Tier: All Green is a yakuman hand, meaning it is a highest-scoring hand that grants the maximum points. Typically, this results in 32,000 points for the dealer and 48,000 points for a non-dealer.

What is the Strategy and Risk of All Green?

Very Rare Hand: All Green is one of the rarest hands in Riichi Mahjong because it requires the player to collect specific green tiles from the Sou suit and the Green Dragon tile. Since green tiles are relatively rare compared to other tiles, it is difficult to gather the right combination of tiles to complete this hand.

Triplets and Quads of Green Tiles: The majority of the hand will consist of triplets (pung) or quads (kong) formed using. This means the player must wait for the appropriate green tiles to form the required sets, and this can take a lot of luck in drawing the right tiles. The player can either self-draw the tiles needed to complete the hand or call kong if they already have a triplet of green tiles and are waiting for the fourth matching tile to complete a quad.

No Non-Green Tiles: Since All Green requires a hand composed entirely of green tiles, players will need to discard any non-green tiles to avoid cluttering their hand with unnecessary tiles. The player must keep a sharp eye on the tiles being discarded by others and avoid discarding any green tiles that could help them complete their hand.

Patience and Luck: Like most yakuman hands, All Green requires a great deal of luck in drawing the right tiles to complete the hand. You cannot depend on other players' discards to complete your hand, as All Green or All Terminals might. The hand also requires patience as you may have to wait for the right combination of green tiles to come up, and there is a limited number of such tiles in the wall
