'''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".

For every hand, the dead wall always starts with the very same arrangement.  The [[kan]] draws are always the four tiles clockwise to the dora indicator.  These are the '''rinshanpai''' {{kana|嶺上牌}}, which are only accessible via [[naki|calls]] for kan.  Not necessary but recommended, the first kan draw can be placed to the side of the second kan draw, like in the image to the right.  This is to prevent accidental revealing of that first tile, in case it gets knocked off

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.

The tile immediately before the dead wall is called the '''haiteihai''' {{kana|海底牌}}.  When a kan is made, the current haiteihai will be moved into the dead wall and the tile before it will become the new haiteihai.
The tile immediately before the dead wall is called the '''haiteihai''' {{kana|海底牌}}.  When a kan is made, the current haiteihai will be moved into the dead wall; and the tile before it becomes the new haiteihai.  Barring those kan calls, the last four tiles can individually be marked as the haiteihai, as one after the other are transferred to the dead wall.  Only one tile at a time can be designated as this last tile.
 
Players may physically transfer tiles to the dead wall.  However, the action is discouraged because it is unnecessary.  The position of the last tile can actually 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.  That's if the rinshan draw is properly placed down.

{{main|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.
