Mahjong etiquette: table manners for American mahjong
Good table manners make mahjong faster, fairer and much more fun. Some of these are courtesy; some are actual rules that decide who gets a tile.
Checked and updated October 31, 2026
During play
- Name every discard clearly as you put it down. Other players are listening for the tile they need.
- Wait your turn to draw. Take your tile from the wall only after the player before you has discarded. At tournaments, touching the next tile ends your right to call the previous discard.
- Call clearly and promptly. Say "call" or "Mah Jongg" as soon as you want a tile. A discard can be called until the next player has drawn and racked or discarded.
- Once you commit, you commit. After you touch a called tile or expose tiles, you must take the discard. You cannot change a named discard once it is down.
- Ask before taking a joker. Offer your matching tile and ask the owner for the joker rather than reaching onto their rack.
- Keep your tiles tidy and in your own space, with the right number on your rack. Holding a tile in your hand can lead to a miscount.
- Keep a steady pace. Take a moment to check your card, but do not stall.
When someone declares Mah Jongg
- Leave your own tiles alone. Do not throw in your hand until the winning hand is checked.
- Check the hand against the card together, politely. Mistakes happen, especially with year hands and colours.
- A simple "nice hand" goes a long way.
If a Mah Jongg turns out to be wrong, the rules on Mah Jongg in error apply.
Talking at the table
- In a regular game, do not discuss what you or others are building during a hand. It gives information away.
- Teaching games are different. Agree at the start if hands are open and coaching is welcome.
- Beginners should feel free to ask questions; experienced players should answer patiently.
Money and house rules
- Agree on stakes, payment rules and any penalties before the first hand. How scoring works.
- Settle each hand as you go, or keep a written tally.
- Have the current card for every player. Sharing slows the table down.
Hosting and guest manners
- Hosts: set up the table, tiles, racks and a spare card before guests arrive.
- Guests: bring your own card. Snacks or drinks are a welcome extra.
- Keep food and drinks off the playing surface; sticky tiles are nobody's friend.
Tournament manners
Tournaments follow the League's standard rules strictly, and directors enforce them. One tournament organizer, Mah Jongg Fever, lists penalties such as these:
- Misnaming a tile that another player calls for an exposure: minus 10 points.
- Discarding the tile that gives a player Mah Jongg when they have 2 exposures: minus 10; with 3 exposures: minus 25.
- Picking from the wrong end of the wall, or holding the wrong number of tiles, can make your hand dead.
Penalties vary by tournament. Read the rules for the event you enter.
Common questions
Do you have to say the name of your discard?
Yes. Name every discard clearly as you put it down, for example "five bam". Other players rely on it to decide whether to call, and in tournaments misnaming a called tile can cost points.
Can you pick up your tile before the previous player discards?
Wait. Pick from the wall only after the player before you has discarded. In tournament play, once you touch the next tile you lose the right to call the previous discard.
Is it rude to take a long time on a turn?
A few seconds to check your card is normal. Keep things moving without rushing anyone, especially beginners.
Should you help a beginner at the table?
In a friendly game, yes, if they ask. Avoid telling other players what to discard during a hand unless the table has agreed to an open, teaching game.
What do you do when someone calls Mah Jongg?
Stop, leave your own tiles where they are, and check the winning hand against the card. Do not throw in or expose your tiles until it is confirmed.
Do you have to ask before taking a joker?
Yes. Hand over your matching tile and ask for the joker; do not reach onto another player's rack and take it.
Should I bring something to a mahjong game?
Not required, but snacks or drinks for the host are appreciated, as is your own current card.
