Signle-wait Four Concealed Triplets

What is Single-Wait Four Concealed Triplets in Japanese Mahjong

Four Concealed Triplets with a Single Wait is an exceptionally rare and high-scoring hand in Riichi Mahjong. It demands that a player form four fully concealed triplets and be in a situation where only one specific tile will complete their hand. The combination of secrecy, precise tile management, and the single-tile wait requirement makes this hand one of the most difficult and rewarding achievements, meriting a double Yakuman score.

How to Achieve Single-Wait Four Concealed Triplets？

Four Concealed Triplets: A triplet consists of three identical tiles. "Concealed" means that all four triplets in the hand have been formed without claiming any discards from other players. They are built solely from the tiles drawn by the player, remaining closed and hidden until the hand is complete. Under normal circumstances, achieving four concealed triplets itself is a Yakuman—one of the highest-scoring hands in Mahjong.

Single Wait: A "wait" refers to the specific tile(s) a player needs to complete their hand. A single wait implies that the player is waiting for one specific tile to complete the hand, with no alternative options.

What is the Strategy and Risk of Single-Wait Four Concealed Triplets?

Hand Development: To aim for Single-Wait Four Concealed Triplets, a player must plan their hand from the outset with a focus on drawing and keeping tiles that can form triplets while avoiding calls. This often involves discarding tiles that don’t contribute to potential triplets or the required pair.

Risk vs. Reward: Pursuing such a hand is high risk, as the player may pass up more modestly scoring opportunities to chase this elusive goal. It requires patience, careful observation of opponents’ discards, and a bit of luck.

Game Impact: Successfully completing Single-Wait Four Concealed Triplets can dramatically swing the game in the player’s favor due to the enormous point value, often leading to an immediate win or a significant lead.
