Mahjong Seat Wind: Value and Rotation

A Mahjong seat wind is the wind assigned to one player for the current hand: East, South, West, or North. It identifies the dealer and table relationship. In Riichi and many Chinese-style rules, a triplet or quad of your own seat wind also has scoring value.

Seat wind at a glance

Mahjong Seat Wind: Value and Rotation: Term, Applies to, Typical role in Riichi

Term	Applies to	Typical role in Riichi
Seat wind	One player for the current hand	Dealer identity and yakuhai value
Round wind	The whole table for a round	Yakuhai value for every player
East	Current dealer	Pays and receives larger score shares
Double wind	Same tile is seat and round wind	2 yakuhai; pair receives 2 fu under WRC

Seat wind and round wind coexist. A South-seat player during the East round has South as their seat wind and East as the table’s round wind.

How to identify the four seats

First identify East, the dealer. Under World Riichi Championship Rules 2025, the other players are South, West, and North in counter-clockwise order around the table.

This can feel reversed to someone imagining a Western compass. Mahjong seat names describe table order, not the geographic direction your chair faces. Turn order is also counter-clockwise: East, South, West, North, then East again.

Initial seats are assigned randomly before the game. WRC documents traditional and direct wind draws and permits another fair table-determined system when organizers announce it consistently. A casual group can roll dice or draw face-down wind tiles, but should agree before building the wall.

Seat wind vs round wind

The seat wind changes with dealer rotation. The round wind remains fixed while each player has the opportunity to become East, subject to dealer repeats.

A standard hanchan has an East round followed by a South round. During East 2, for example:

• the table’s round wind is East;
• the current dealer’s seat wind is East;
• the next player in turn order is South seat;
• the next is West; and
• the final player is North.

When the initial East player becomes East again after the appropriate rotations, the East round ends and the marker changes to South. Seat and round names are therefore independent clocks.

Why a seat wind can be a yaku

In Riichi, a triplet or quad of your seat wind is yakuhai, a one-han yaku. A triplet or quad of the round wind is also one han. Dragon triplets and quads receive the same one-han value-honor treatment.

Suppose you are South seat during the East round:

Mahjong Seat Wind: Value and Rotation: Wind set, Yaku value for you

Wind set	Yaku value for you
South triplet	1 han: seat wind
East triplet	1 han: round wind
West triplet	0 han by itself
North triplet	0 han by itself

West or North may still support another yaku, such as all honors, or add fu. They simply are not yakuhai for that player in that hand.

What is a double wind?

A double wind occurs when your seat wind matches the round wind. East seat in the East round and South seat in the South round are common examples.

Under WRC rules, a triplet or quad of that wind scores yakuhai twice: once for seat and once for round. A pair of the double wind receives 2 fu, not 4 fu under this ruleset. Other Riichi organizations have historically differed on double-wind pair fu, so label the scoring standard.

A wind pair does not create yakuhai; the yaku requires a triplet or quad. It can still affect pinfu because a pair of seat wind or round wind is a value pair and invalidates that yaku.

Dealer value and payment

East is the dealer. In Riichi, an East winner receives higher payments, and East also pays a larger share when a non-East player wins by tsumo. The dealer begins with the first discard after the initial 14-tile hand.

Being East is therefore valuable but risky. It is not a permanent advantage assigned to one chair. Rotation gives each player dealer opportunities over the game.

When seat winds rotate

WRC seats remain unchanged when:

• East wins; or
• nobody wins at an exhaustive draw and East is tenpai.

Seats rotate when:

• South, West, or North wins; or
• nobody wins and East is noten.

On rotation, South becomes the new East. The former East becomes North, while West becomes South and North becomes West. Continue to think in counter-clockwise turn order rather than moving physical chairs.

Dealer repeats add a honba counter. Under WRC rules, each counter increases the next win by 300 points. The counter can remain through a draw and is removed when a non-East player wins, following the full payment procedure.

Seat winds in other Mahjong variants

Many Chinese regional games use seat winds, prevailing winds, or dealer status, but scoring and rotation differ. A flower number may correspond to a seat, winds may receive fan, and dealer repeats may follow different draw conditions.

American Mah Jongg includes wind tiles, yet legal hands come from the annual card. Do not automatically award a seat-wind yaku or Riichi fu in American play.

A practical table check

Before every hand:

1. Point to the current East player.
2. Name South, West, and North counter-clockwise.
3. Check the round marker separately.
4. Identify which wind triplets would be yakuhai for your seat.
5. Update seats only after the hand’s win or draw result is settled.

Use a visible wind marker and keep the dealer’s honba sticks in a consistent location. If an automatic table shows seat labels, still verify that its rule settings match the game.

The key memory aid is: seat wind belongs to you; round wind belongs to the table. Read both before valuing a wind tile.
