Wanpai: Difference between revisions

Latest revision as of 05:28, 9 January 2025

Wanpai 「王牌」 are the tiles used to form the dead wall, a set of 14 tiles (7 double-stacks) set aside from the regular tile draw and discard processes. At the start of each hand, a new group of 14 tiles are randomly picked. These tiles are used to indicate dora and for kan draws.

Arrangement

The fourteen tiles for the dead wall are arranged accordingly. Also, the last four tiles to the live wall are also included.

Dead wall							End of live wall

1st kan draw	3rd kan draw	Dora indicator	1st kandora	2nd kandora	3rd kandora	4th kandora	2nd haiteihai	4th haiteihai

2nd kan draw	4th kan draw	1st uradora	2nd uradora	3rd uradora	4th uradora	5th uradora	1st haiteihai	3rd haiteihai

The dead wall always starts with this arrangement. The kan draws are always the four tiles clockwise to the dora indicator.

Optionally, the first kan draw can be placed to the side of the second kan draw, like in the image to the right, to prevent accidental revealing if it gets knocked off.

Dora

Main article: Dora

The dead wall is always responsible for indicating the dora. At the start of each hand, the third tile on the top row is revealed and becomes the dora indicator (dorahyouji' 「ドラ表示」). The tile one number up from the revealed tile is the dora.

For every kan, the next tile from the wall break is revealed and becomes another dora indicator.
After a player wins with riichi, any tiles underneath each revealed dora indicator are revealed and become ura dora indicators.

Haiteihai

Main article: Haiteihai

The tile immediately before the dead wall is called the haiteihai 「海底牌」. When a kan is made, the current haiteihai will become part of the dead wall, and the tile before it becomes the new haiteihai. (The tile may be physically moved after a kan, but this is discouraged as it is unnecessary.)

The position of the last tile can be tracked as the hand nears the end. As a general tip, the last tile is trackable by counting six tiles on the top of the dead wall, if the rinshan draw is properly placed.

Kan

Main article: Kan

Calls for kan affect the dead wall in three ways:

The player calling kan is then required to draw from the dead wall via the rinshanpai.
A tile from the back end of the wall, the haiteihai, is transferred to the dead wall.
The tile next to the dora is revealed.

For every kan call, a player gains access to the dead wall and draws one rinshanpai. If the rinshanpai produces a winning tile, then this draw invokes the yaku, rinshan kaihou. Under most cases, players make a discard afterwards. After that discard, one tile from the end of the regular wall is added to the dead wall to the back end. This is to retain the count of 14-tiles. Unlike the original dead wall tiles, the added tiles can serve no function, other than as replacement tiles. Finally, an additional dora indicator is revealed.

+'''Wanpai''' {{kana|王牌}} are the tiles used to form the '''dead wall''', a set of 14 tiles (7 double-stacks) set aside from the regular tile draw and discard processes. At the start of each [[kyoku|hand]], a new group of 14 tiles are randomly picked. These tiles are used to indicate [[dora]] and for [[kan]] draws.
-'''Wanpai''' {{kana|王牌}} are the tiles used to form the '''dead wall'''.  These tiles are set aside from the regular draw and discard play.  Every mahjong hand session has 14 tiles, or 7 double-stacked tiles, set aside from the regular tile draw and discard processes.  These tiles are considered to be out of play, hence the nomenclature "dead wall".
-==Use==
-Dead wall tiles are generally inaccessible, unless players call [[kan]].  Here, four tiles counterclockwise from the dora indicator are dedicated to kan calls.  Even then at all times, the dead wall must be maintained at 14 tiles.  In the event of a kan call, a tile is drawn by the player; and so a replacement tile from the end of the regular wall is added to the end of the dead wall.
-The dead wall also holds the '''rinshanpai''' {{kana|嶺上牌}}, which are only accessible via [[naki|calls]] for [[kan]].  They are the four tiles between the dora indicator and the first cut of the wall.  In other words, they are the four tiles immediately clockwise from the dora indicator.  For every kan call, a player gains access to the dead wall and draws one rinshanpai.  After a discard, one tile from the end of the regular wall gets added to the dead wall, to retain the count of 14-tiles.  If the rinshanpai produces a winning tile. then this draw invokes the yaku, [[rinshan kaihou]].
-=== Dora ===
-{{main|Dora}}
-The dead wall is always responsible for indicating the dora.  Among the dead wall, one tile is flipped and revealed for everyone.  This tile is assigned as the '''dorahyouji''' {{kana|ドラ表示}}, or "dora indicator".  It is always the third tile on the top row from the initial wall break.  Tiles marked as dora are indicated as the next tile in the sequence, as noted in the "[[Dora#Dora order|dora order]]".
