Choose Your Level

Every session welcomes all three divisions — you just need to find your fit.

Beginner (2.0) You know the basics but you still like having an expert nearby for rules questions. An instructor is on-site at every match to help with rules (not strategy), so you can play at ease.

Beginner+/Intermediate (2.5-3.0) You keep a steady, confident pace — typically 2-3 games per hour. This division is for players who know their way around the wall and want consistent, competitive company.

Intermediate+/Advanced (3.5-4.0) You play fast, and you play to win — usually 3-4 or more games per hour. Built for players who want quick decisions, sharp opponents, and a real competitive rhythm.

We will reach out to you prior to the first match to find out your skill level and place you in the appropriate league.

How League Play Works

Match Format 

Each league match consists of two 55-minute rounds, with a five-minute break between rounds. Each player will be assigned to a table of four for each round. Table assignments will rotate after the first round.

Players may complete up to four games per round—but four is a limit, not a requirement. There is no penalty for completing fewer games. Play at your division’s natural pace, and let the games you finish speak for themselves.

Record the score for every completed game, up to four games per round. Score sheets will be provided.

The NMJL rules printed on the current card will serve as the league’s official rules. Montahj Social may establish supplemental league rules as needed. All rules questions will be resolved by Montahj Social instructors, whose decisions will be final. Additional league rules and etiquette guidelines will be shared with participants before the league session begins.

Scoring

Step 1: Determine Performance Points at the End of Each Round

Performance Points = NMJL Value + bonus points - penalty points

  • +NMJL value awarded to the winning player
  • +5 bonus points for self-drawing the winning tile for Mahjong+10 bonus points
  • 0 points for a wall game, a dead hand, or an incomplete game at the time limit-5 penalty points
  • +10 bonus points for a jokerless hand (excludes Singles & Pairs)0 points
  • -5 penalty points if you're not seated and ready to play at the start time
Step 2: Convert to Standing Points

At the end of each round, the four players at your table are ranked by Performance Points. Standing Points are awarded based on that rank:

  • 1st Highest Performance Points = 3 Standing Points
  • 2nd Highest Performance Points = 2 Standing Points
  • 3rd Highest Performance Points = 1 Standing Points
  • 4th Highest Performance Points = 0 Standing Points
Step 3: Determine the Match Winner

Standing Points are added up across every round in the match. Whoever has the most Standing Points at the end wins — not whoever racked up the most Performance Points in a single game.

Tiebreakers

Round Tie (Performance Points): If Performance Points are tied at the end of a round, the tie will be broken based on the following priority: 

  • Most Mahjongs → highest-value winning hand → highest total value of all winning hands before bonuses → coin toss

Match Tie (Standing Points): If Standing Points are tied at the end of the match, the tie will be broken based on the following priority: 

  • Most cumulative Performance Points → most cumulative Mahjongs → highest-value winning hand → highest total value of all winning hands before bonuses → coin toss

Entering Scores

Every player must sign the scoresheet to confirm accuracy. Give scoresheets to the instructor before leaving the match. Scores will count toward your rating — the more you play, the more your rating and ranking reflect it.

Final Ranking - League Winner

League standings are cumulative: most matches won takes the top prize. Ties are broken by:

  • Most cumulative Performance Points → most cumulative Mahjongs → highest-value winning hand → highest total value of all winning hands before bonuses → coin toss  

Prizes

Beyond the games themselves, league play comes with real stakes:

  • The top player in each division wins a $25 credit toward any Montahj Social event or retail item
  • Recognition in the newsletter and online
  • League winners qualify for championship tournaments
  • Sportsmanship Award — nominate a fellow player who shows kindness, patience, team spirit, and fun
