Four Concealed Pungs

What is Four Concealed Triplets in Japanese Mahjong

Four Concealed Triplets is a yakuman (highest-scoring hand) in Japanese Riichi Mahjong. Four Concealed Triplets is a yakuman yaku that requires a fully concealed hand with four triplets (or pung), all self-drawn, and one pair. It is one of the most difficult hands to achieve because you are not allowed to make any calls or interact with other players' tiles, and all the tiles needed for the triplets must come from the wall. This hand is extremely rare and rewards players with a yakuman payout, making it one of the most prestigious hands in Riichi Mahjong.

How to Achieve Four Concealed Triplets？

Four Concealed Triplets: The hand must consist of four triplets made up of three identical tiles each. These four triplets must be concealed; that is, they must be formed by self-drawing all the tiles. You cannot call pung or kong (melds) from other players to form any part of this hand.

No Calls: You cannot make any calls during the game. This means no melds are allowed, and your entire hand must be constructed from tiles you have drawn yourself. If you call any tile from another player (for a pung, kong, or chow), it disqualifies your hand from being a Four Concealed Triplets.

One Pair: As with all winning hands in Riichi Mahjong, you still need a pair in addition to your four triplets. The pair can be any tile that completes the hand’s structure, but it cannot be part of a triplet.

Yakuman Tier: Four Concealed Triplets is a yakuman (maximum-scoring hand), which grants the highest base score available for a single hand. For most scoring systems, this results in a payout of 32,000 points for the dealer and 48,000 points for a non-dealer.

What is the Strategy and Risk of Four Concealed Triplets?

No Melding or Calling: Since Four Concealed Triplets requires a fully concealed hand, your strategy revolves around self-drawing tiles that help complete the triplets. You will need to draw the correct tiles at the right time to form the four triplets without ever needing to call or meld tiles from opponents.

Patience and Luck: Four Little Winds is heavily dependent on luck because you have no control over what tiles are discarded by your opponents. You can’t rely on their tiles to complete your hand. You will need to wait for the right tiles to come up in the wall, and your hand’s structure must come together naturally.
