NMJL
All National Mah Jongg League rules apply.

Standard Scrambles
Every Standard Scramble match has four games, with each player East once.

Social vs. Focused
All matches use the same rules. Social has a more relaxed pace expectation. Focused requires a faster pace.

Proposer equipment
The current match proposer provides the Mahjong tiles, mat, racks and dice. If the proposer leaves an open match, proposer responsibility transfers to the next player who joined.

Charleston passing
All four players must place their tiles on the mat before anyone picks up incoming tiles.

Phones
No phone above table height. No photos of tiles, racks, hands or the table. No AI or electronic assistance.

Notifications
All phone notification sounds must be turned off during play, as a courtesy to other players and to encourage everyone to stay present and focused on the game.

Scoring
Winner receives the NMJL hand value shown on the card.
Self-picked Mahjong = hand value ×2.
Jokerless Mahjong = hand value ×2 when eligible.
Self-picked + Jokerless = hand value ×4.
50- and 75-point hands are not eligible for the Jokerless multiplier.
Wall Game = +10 to each player and no other points for that game.
Average score is shown only after a player has completed at least 4 matches.

Standard Scramble proposer
In Standard Scrambles, the proposer at the time the match is completed receives +5 points.

Withdrawal
Leaving less than 24 hours before the match: −20 if no replacement joins and the match is cancelled.

Late
20 minutes or more late AND the delay results in the match being cancelled: late player −20 points; other three players +25 points each.

Emergency
If an emergency occurs after play begins, every unfinished game becomes a Wall Game, +10 to each player.
