JM Mahjong was created to give players the most enjoyable and rewarding experience every time they play.

The joy and rewards of mahjong: it sharpens the mind, strengthens memory, and forges supportive, lasting friendships.

My goal is to create games that emphasize skill over luck and bring greater enjoyment to more players

Mahjong tournaments are the ultimate challenge—offering incredible fun for players who truly appreciate the game..

By increasing the share of players who earn prizes, staging championship-style tournaments, or using team‑format tournaments, I minimize luck’s influence and let the skill stand out.

Mahjong Game at Home

Games at Home

Either one table or eight tables, the comfort of the home game is irresitiable and the four automatic mahjong tables add more fun vibe for the game.

The games outside the house

Games on Cruise

Team Tournaments

By running team tournaments in dedicated locations, JM Mahjong transforms mahjong into a more exhilarating experience.

Why and How I Make the Games Differently

Winning is the ultimate thrill, yet the slim odds in tournaments can be discouraging. Out of my love for the game, I’m willing to put in all the effort needed to make mahjong tounaments more enjoyable for everyone—and to ensure our tournaments remain vibrant and sustainable for the long haul.

Transparency Fosters Trust

I am committed to clear communication ensures everyone knows where they stand, either openly sharing decisions and the reasoning behind them or upholding transparency and honesty around rules and tournament outcomes.

50%

Rewarded

By optimizing prize payouts, in tournaments with up to six tables, 50% of players walk away with a prize.

Foster

skills

Whether it’s league play, team tournaments, or a five‑day championship, spreading competition over multiple days and larger player pools helps offset the luck factor of a single day’s and single player’s results.

Randomness Ensures Fairness

No one knows their opponents in advance. With no preassigned seating, each player or team draws their seats at random just before the tournament—ensuring complete fairness.

The 4‑Auto‑Table Tournament is the flagship of JM Mahjong

Automatic tables paired with our random‑seat protocol ensure every player an equal shot, while the sleek, innovative tables create a premium “tournament‑pro” atmosphere that’s both special and memorable.

By creating the “4‑Auto‑Table Championship,” JM Mahjong establishes its reputation as an innovator—and puts Northport on the map as a local mahjong hotspot.

Monday Tournament

If you love pizza, meatballs, pasta, and fresh salad, our Italian‑themed Monday tournaments are for you!

Tuesday Tournament

Taco Tuesday flows nicely with our group who love Mexican‑style flavors that keep the fun going strong!

Wednesday Tournament

Golden China’s fame has spread past Northport thanks to our Chinese‑food‑themed Wednesday tournaments.

Thursday Touranment

With a surf‑and‑turf menu, my husband Richard’s BBQ prowess is on full display for the perfect steak.
