Dora (ドラ) is a feature to the game, where possession of specific tiles instantly grants the hand 1 han per tile. Regardless, hands must still possess a yaku in order to score, regardless of the number of dora in the hand. At the start of every hand, 14 tiles are set aside as the wanpai, or dead wall tiles.
Dead wall
Wanpai are the tiles used in the dead wall. Every mahjong hand session has 14 tiles set aside from the regular tile draw and discard processes. These tiles are designated as the dead wall, and they are considered to be out of play. Among the dead wall, one tile is flipped and revealed for everyone. This tile is assigned as the dorahyouji (ドラ表示), or "dora indicator". Tiles marked as dora are indicated as the next tile in the sequence. For example, if the dora indicator shows 
, then the dora tile is 
.
Dora order
This lists the complete dora order. As a repeat, the dora is the next tile within each of the following orders. Dora are not "cross indicated" among the different suits. Furthermore, the dora order loops.
Suit order
If the dora indicator is , then the dora is .
If the dora indicator is , then the dora is .
If the dora indicator is , then the dora is .
Wind order
If the dora indicator is , then the dora is .
Dragon order
If the dora indicator is , then the dora is .
Duplicated dora
In the event a dora indicator is repeated, either as a kandora or uradora, then the dora tile is worth the number of han as the dora indicator shows.
Example:
- Dora indicators
A single 
is worth 2 han.
Other types of dora
Additional indicators of dora may be found in the game.
Akadora
Akadora are specifically marked red tiles. If included in the game, these "red fives" automatically count as dora, regardless of the dora indicator. If the dora indicator is a four, the red five of the same suit counts as two dora.
Red haku
Though rarely found, some older sets include a "red haku" tile (white dragon).
Uradora
This applies only to hands won using riichi. In the event a riichi declared hand has won, the tiles underneath the dora indicator(s) are revealed. These newly revealed tiles serve as additional dora indicators. Potentially, such hands may potentially gain substantial value, just off of the ura dora.
If there are multiple identical indicators, each indicated tile counts as multiple dora correspondingly.
Kandora
After a call for kan, additional dora indicators are flipped. These are tiles next to the dora indicator counter clockwise on the dead wall. Depending on the rules and/or formality of the game, the timing for flipping the kandora during a kan procedure may vary. Casual games will simply flip the kan dora immediately after kan. More technical games will differentiate between the kan types, where the kan dora may be flipped after the player makes a discard.
Likewise, in the event of riichi, the uradora underneath the kandora are also revealed, as kanuradora.
