Table Reading

How to read public discards.

The discard pool is shared information. It tells you what is gone, what is risky, and when your own target hand needs to change.

American Mah Jongg

Dead Tiles

If all copies of a needed tile are visible in discards or exposures, the hand line that needs that tile cannot complete naturally.

Danger Tiles

A discard becomes dangerous when it matches exposed groups or likely target lines for another player.

Timing

Early discards can be exploratory. Late discards are more meaningful because players have had time to commit to a target.
