American Mahjong Scoring: Who Pays What

Scoring in American Mahjong looks intimidating, but the whole system fits in a few sentences. Every hand on the NMJL® card has a value printed next to it. When someone wins, the other three players pay them based on that value — and only three things ever change the amount.

Start with the printed value

The number at the end of each line on the card is that hand's value. Harder hands are worth more; the exact values are printed on the current year's card (we can't reproduce them here). In a basic win off a discard, each non-discarding player pays the printed value.

The discarder pays double

If you win by calling another player's discard, the player who threw your winning tile pays double the hand's value. The other two players pay the normal amount. It's the game's built-in penalty for feeding the winner — and the reason defensive discarding matters.

Self-draw: everyone pays double

If you draw your winning tile from the wall yourself — a self-draw — there's no discarder to blame, so all three players pay double. A self-draw win always collects more than a discard win.

The jokerless bonus

Win with no Jokers anywhere in your hand and every payment doubles again, on top of whatever it already was. So a jokerless win off a discard means the discarder pays four times the printed value and the others pay double.

One important exception: Singles & Pairs hands can never use Jokers, so their higher difficulty is already baked into the value printed on the card. Don't apply the jokerless double to them — just use the printed number.

What you don't need to memorize

You never need to memorize hand values — they're right on the card. The only mental math is the multipliers: discarder ×2, self-draw ×2 for everyone, jokerless ×2 on top. Our scoring calculator does the arithmetic for you while you learn.
