American Mahjong Scoring Explained: How NMJL Points Work

How American (NMJL) mahjong scoring works — what the number on the card means, who pays the winner, and why self-picking your winning tile pays double.

5 min read

American (NMJL) mahjong scoring is simple by design: every hand on the card has a point value printed next to it, and when you declare Mah Jongg you collect that value from each opponent. The player who discarded your winning tile pays double; if you self-picked the winning tile from the wall, all three opponents pay double. There is no han or fu calculation — the card does the math for you.

If you have not learned to read the card yet, start with how to read an American mahjong card, then come back here for what those numbers actually pay out.

Note: This covers standard National Mah Jongg League (NMJL) scoring. Clubs and home games often add house rules (jokerless doubles, penalties for errors). Confirm the rules at your table before you play, and check the current year’s official card for hand values.

The One Thing That Makes American Scoring Easy

In Japanese riichi, scoring is a calculation — you count han and fu and look up a payment. American mahjong removes all of that. Each legal hand is printed on the NMJL card with its value already assigned, from 25 points for the simplest hands up to 75 or more for the hardest. You never compute a score; you read it.

That single design choice is why beginners can play American mahjong competently on day one. The hard part is reading the card and building a hand — not scoring it.

What the Number on the Card Means

Next to every hand on the card is a number. That number is the value of the hand — what each opponent owes you if you complete it and win. A rough sense of the range:

Card valueTypical hand difficulty
25The easiest hands — common patterns, exposed play allowed
30–40Moderate hands, often needing two or three suits
50Harder hands, frequently concealed
60–75+The toughest hands, including most of the Singles and Pairs section

Higher numbers are tempting, but they are harder to finish. The smart beginner play is to chase a 25 or 30 hand your tiles already support, not a 75 hand you will almost never complete. Win rate beats hand value.

Who Pays, and How Much

When you declare Mah Jongg, all three opponents pay you — but how much depends on how you won.

Won off a discard:

  • The player who discarded your winning tile pays double the card value.
  • The other two players each pay the face value (single).
  • So a 25-point hand won off a discard collects 25 + 25 + 50 = 100 points total.

Won by self-pick (off the wall):

  • All three opponents pay double.
  • A 25-point hand self-picked collects 50 + 50 + 50 = 150 points total.

This is the heart of American scoring strategy: self-picking your winning tile pays 50% more than winning off the same-value discard. It is also why a careful player will sometimes pass on claiming a discard, holding out for the self-draw.

A Worked Example

Say you complete a hand worth 30 points on the card.

  • Off a discard: the thrower pays 60, the other two pay 30 each → you collect 120.
  • Self-picked: each of the three pays 60 → you collect 180.

Settlement is done with the coins or chips that come in your set — you simply count out the values. No table-wide math, no rounding tables.

Penalties and Dead Hands

A few situations cost you instead of paying you:

  • Calling Mah Jongg incorrectly (your hand does not actually match a card line) typically makes your hand dead — you are out for the rest of that hand and may owe a penalty depending on table rules.
  • An exposure that does not match any hand can also kill your hand.
  • A wall game (the tiles run out with no winner) usually means no one pays — everyone simply re-deals.

When in doubt, verify a hand against the card before you declare. A wrong call is the most expensive mistake in the American game.

House Rules to Confirm

NMJL clubs and home tables frequently add rules that change the math. The most common:

  • Jokerless double: a hand built without any jokers pays double its card value.
  • Penalty pools: wrong calls or dead hands pay into a pot.

None of these are standard NMJL tournament rules — so ask before the first hand.
