2.7 The dora indicator
Count three tiles into the dead wall from the original break in the wall, and turn the top
tile over to determine the dora indicator. This tile indicates which tile is dora. If the dora
indicator is a suit tile, the dora is the next tile in the same suit, e.g. seven bamboo is dora
if six bamboo is the dora indicator. If the indicator is a nine, the dora is the one in the
same suit. If the indicator is a dragon, the dora is also a dragon, as the following order
applies: red points to white, white points to green and green points to red. For winds,
likewise, the following order applies: east-south-west-north-east.
