Therefore, if you have {{#mjt:14s}} in your hand, the {{#mjt:1s}} is extra bad, since it only adds 1-sou to the joint acceptance (making the tile just slightly better than a guest wind). | ||

Note: When this shape contains a terminal tile (1 or 9), it becomes much worse. It's still good if you need a pair, but the ryanmen acceptance is halved, equal to a regular floating tile. | Note: When this shape contains a terminal tile (1 or 9), it becomes much worse.

Specifically, when two tiles are equally useless, you should discard the tile that is more dangerous first. Usually the more dangerous tile is the tile closer to the middle. | ||
