For Experienced Players
American Mah Jongg Quick Reference
Short reminders for players who already know the table flow and need quick confirmation during a game.
Call A Discard
- Only the most recent discard is live.
- Call for Pung, Kong, Quint, or Sextet.
- Do not call for Single or Pair unless it wins.
- After exposing, discard one tile.
Concealed
- C means no exposure during play.
- You may call the final tile only to declare Mah Jongg.
- An exposed concealed hand is dead.
Jokers
- Allowed in groups of 3 or more.
- Not allowed in Singles or Pairs.
- Can be exchanged on your own turn with the matching natural tile.
Win Check
- Exactly 14 tiles.
- One complete current-card line.
- Correct suits, Flowers, Winds, Dragons, and zeroes.
- Legal Joker use and legal exposures.
Payment
- Discard win: discarder pays double, others single.
- Self-pick: all players pay double.
- Jokerless may double, except where already built into the section value.
Defensive Reminder
Before you discard, scan the table.
Late-game discards that match an opponent's exposure.
Flowers when another player has exposed Flower groups.
Dragons matching a visible suit pattern.
A tile that completes an obvious Pung, Kong, or Quint.
