American Mah Jongg (NMJL)
Four-player scoring for standard home games. Pick a mode when you create a group — mahjilla records wins and applies the rules below.
Settle up
Official home game. Zero-sum — the winner collects, everyone else pays.
The official NMJL home-game settle-up most tables use — zero-sum, everyone pays the winner.
Official home game. Zero-sum — the winner collects, everyone else pays.
How scoring works
- The winner collects; every other player pays based on the hand value.
- Self-pick: everyone pays double what they would otherwise owe.
- Discard win: the player who threw the tile pays double; everyone else pays the base amount.
- Jokerless: doubles the payment again (stacks with self-pick or discard doubling).
- Wall game: no winner, no points change hands.
What you'll record each game
- Who won and how (discard, self-pick, or wall game)
- Hand value from the 2026 NMJL card
- Who threw the tile — discard wins only
- Jokerless only when the hand earns the jokerless bonus — not Singles & Pairs
Win types at your table
Won off a discard
Someone called mahj on a discard — another player fed them the winning tile.
In Settle up: Winner collects the hand value from each loser. The discarder pays double.
Self-pick
They picked the winning tile themselves — nobody threw it.
In Settle up: Winner collects double the hand value from every other player.
Wall game
The wall was exhausted and nobody mahj'd. No winner for that hand.
In Settle up: No winner. Scores stay put — nothing is exchanged.
Example
A 25-point discard win: three losers each owe 25, but the discarder owes 50. Jokerless would double those amounts again.
Singles & Pairs and jokers
On the NMJL card, Singles & Pairs hands cannot use jokers and do not get the jokerless bonus.
- Jokers may only substitute in pungs, kongs, and quints — never in a single tile or a pair.
- Hands in the Singles and Pairs section of the card are built from natural tiles only.
- The jokerless bonus (double in settle-up, extra points in additive/Siamese) applies only when the hand could have used jokers but did not.
- Singles & Pairs never qualify — score the card value only and leave Jokerless unchecked in mahjilla.
Check Jokerless when…
- The hand is from any other section (2025, 2468, Consec, etc.) and was won without jokers.
Leave Jokerless off when…
- The winning hand is from the Singles and Pairs section of the card.
- The hand used one or more jokers.
mahjilla does not read the card for you — pick the hand value from the line and choose Jokerless based on the rules above.
Additive
Tournament style. The winner banks the hand value plus bonuses.
Tournament-style tracking where only the winner gains points and nobody goes negative.

Win types at your table
Won off a discard
Someone called mahj on a discard — another player fed them the winning tile.
In Additive: Winner gets the hand value. No penalty to the thrower — just the winner's score.
Self-pick
They picked the winning tile themselves — nobody threw it.
In Additive: Winner gets hand value plus your self-pick bonus.
Wall game
The wall was exhausted and nobody mahj'd. No winner for that hand.
In Additive: No winner. Each player receives your wall bonus.
Example
A 30-point self-pick with a 10-point self-pick bonus: the winner banks 40. Everyone else stays unchanged.
Bonus points (additive only)
- Self-pick — Extra points when the winner drew the tile themselves.
- Jokerless — Extra points when the hand earned the jokerless bonus — never for Singles & Pairs.
- Wall — Flat payout to everyone when the hand ends in a wall game (additive only).

Win count
Simplest of all. One point for the win, nothing else counts.
The simplest leaderboard — count mahjs, ignore hand values and bonuses.

How scoring works
- One point per win. Hand value, jokers, and how they won don't change the score.
- Wall games don't add a win to anyone.
- Great when you only care who mahj'd the most.
What you'll record each game
