Winning tile: 4m

How Closed Wait (坎張) works

Winning on the single middle tile that fills a gap inside a sequence — for example holding 4 and 6 and winning on the 5.

The winning tile completes a chow from the inside, where only that one specific middle tile could finish the run. It is a wait-type fan describing the shape of the final wait, not the overall hand. It applies only when the completed group is a chow and the wait was the single enclosed tile.

Good to know
  • The wait must be the enclosed middle tile of a sequence (a one-tile wait).
  • It rewards the chow-completing wait, not pungs or pair waits.
  • Only one wait fan among closed/edge/single applies to the winning tile.

Closed Wait (坎張) — FAQ

Does it count if I could also have completed the chow another way?

No. The wait must genuinely be only the single middle tile; if other tiles also completed the hand it is not a closed wait.

Is winning on the 3 of a 1-2 shape a closed wait?

No. That is an edge wait; closed wait is specifically the trapped middle tile, like the 5 between 4 and 6.
