Exposures & Defensive Play in American Mahjong

When you call a discard in American Mahjong, you expose tiles face-up on your rack. This reveals information about your hand to opponents. Balancing the need to complete your hand against the information you reveal is a key strategic skill.

When to Expose

Expose when the called tile significantly advances your hand. Avoid exposing early when you haven't committed to a specific hand pattern.
