American Mah Jongg Strategy: From First Pass to Final Discard

A decision framework for flexibility, hand selection, information, defense, and the changing value of tiles across a round.

Working outcomeA five-stage model for evaluating the next decision.

Strategy starts with the information state

Your rack, the current authorized card, visible exposures, discards, and the remaining wall create a changing evidence set. Separate what is known from what is merely plausible before choosing.

The five stages

Use different priorities during opening structure, Charleston, early commitment, table-reading, and endgame defense.

  • Preserve flexible relationships early.
  • Compare realistic hand paths after each information change.
  • Increase defensive weight as the wall shortens.

Review decisions, not outcomes

A strong choice can lose and a weak choice can win. After the round, reconstruct the evidence available at the moment rather than judging only from the final draw.
