Help and Questions



How to play Mah Jongg is a great place to learn if you are new to the game! I'd recommend getting started by playing against the computer players before jumping into a game with other people.

If you are still learning to play or looking for tips and tricks to become a better player, I highly recommend "Let's Play Modern American Mah Jongg! A Flipbook Reference Guide" from 26th Avenue Press. This is a fantastic reference to keep with you at the table!

For an online tutorial, I recommend the great tutorial at Yellow Mountain Imports

If you know the rules but want to see a tutorial video on how to get started on, check out this video:

Dead hands will automatically rule your hand dead if:

  • You declare Mah Jongg and your hand doesn't match any hand on the card that you are playing.
  • You declare Mah Jongg and your hand matches a hand on the card that you are playing, but the hand played was concealed and you had previously exposed a set of tiles.
  • You expose a set of tiles and your exposed sets don't match any hand on the card that you are playing, or they only match a concealed hand.

If you think your hand was ruled dead in error, PLEASE double-check the following before sending your feedback:

  • Check to make sure that you are playing at a table set for the correct card. You can see which card is in use by opening the sidebar on the right and clicking on the "Card" tab.
  • If you had previously exposed tiles, check that the hand you were attempting is not concealed.
  • Check to make sure that the suits match the rules described on the card for that hand. For example, if the card calls for "two suits", make sure that your hand doesn't consist of a single suit or three suits.
  • Check to make sure that you haven't confused two tiles that are similar in appearance. For example, the 1 dot tile appears similar to the joker, and the 1 (bird) Bam looks somewhat like the Flower.

Sneak Preview!

Tile Tutor


The "Card" tab in the game is blank...why? has its own card (the Starter Card), but respects the hard work (and copyrights) of others who publish cards. For that reason, only the card is available from within a game. For other cards, you'll need to purchase your own copy in order to play. For example, is not affiliated in any way with the National Mah Jongg League and therefore can't include their card of hands.

Closing the sidebar

If you are playing on a device with a smaller screen (such as an Apple iPad), it is probably necessary to keep the sidebar on the right closed (unless you need to refer to it) while playing in order to see all of your tiles.

To show or hide the sidebar, just click on the vertical gray bar on the right edge of the screen.

Close sidebar

Viewing discarded tiles

To view the tiles that have been discarded, you'll first need to make sure that the sidebar on the right is open. You can hide or show the sidebar by clicking on the vertical gray bar along the right edge of the screen.

Once the sidebar is open, just click on the "Discards" tab. The tiles are grouped by suit and then by number. The number of each tile that has been discarded will be shown below the tile. If all tiles of a particular type have been discarded, then the tile will be faded out and the count will be shown in red.

How much does Premium cost? Premium is a subscription. There are several pricing options to fit everyone's budget:

Option Cost Billed Every Premium - Monthly $4.99 1 month Less than a trip to the coffee shop! Premium - Quarterly $12.99 3 months Only $4.33 per month! Premium - Semiannually $22.99 6 months Only $3.83 per month! Premium - Annually $39.99 12 months The best value...only $3.33 per month!

All amounts are is US dollars (USD).

Why can't be completely free? Why a limited number of free games per day?

There is a cost to keeping up and running. As the number of players increases, so does the cost. I would like to be self-sustaining so I can continue to improve the site and add new features for a long time to come! I would also like to avoid relying on advertisements which ruin the experience for everyone.

As promised since the site began, you will always be able to play for free. You'll simply be limited to four free games per day. That number was chosen because four games is "once around the table". The free game counter resets each day at 3:00am U.S. central time.

Exposing tiles

You can make an exposure after claiming a tile discarded by another player. After claiming the discard, you first need to select all of the tiles in the set (the discarded tile that you just claimed should already be selected). Once you've done so, the "Expose Tiles" button should be available. Click that to make your exposure.

You must make your entire exposure at one time -- there is no way to add tiles to or modify an exposure once it has been made.

What do the tiles used on the site look like?

Let's start with the Bams:

1B 2B 3B 4B 5B 6B 7B 8B 9B

Here are the Craks:

1C 2C 3C 4C 5C 6C 7C 8C 9C

Here are the Dots:

1D 2D 3D 4D 5D 6D 7D 8D 9D

Here are the Winds:


Here are the Flowers:

F1 F2 F3 F4

Here are the Dragons -- Green, Red, and White:


Finally, here is your favorite tile, the Joker:


See tiles remaining in the wall

There are two places where you can see the number of tiles remaining in the wall:

  1. The gauge across the top of the game board shows the number of tile remaining. It also becomes smaller and changes colors from green to red as the game progresses.
  2. The "Discards" tab in the sidebar on the right also shows the number of tiles remaining.

Customizing the number of popups

The number of popup messages that appear from the top-left corner of the screen can be customized by changing the appropriate setting in the "Settings" popup while playing.

You can choose to show popups:

  • Never
  • For important messages only (chat, exposures, joker trades)
  • Always

Note that if the sidebar on the right is open to the "Chat and Messages" tab, then no popup messages (other than errors) will be displayed regardless of the setting above.

Change popup setting

How do the stars work?

The number of stars is based on your total number of points. As you accumulate more points, it becomes harder to earn the next star:

Stars Points Required
??? 1,000,000
Dead jokers

You may see a joker that is "faded" and outlined in red:

Dead joker

This is because there are no longer sufficient tiles in play to trade for that joker. For example, in the screenshot above, five other flowers have already been discarded. This means that only one of the exposed jokers is available for trade while the other is "dead".

Some players do this when playing at a real table by turning the exposed joker upside down.

What is the "red sword" tile?

Red dragon

That is the red dragon tile.

This is a common way of representing the red dragon. It was chosen because -- unlike all of the other tiles (which are distinguishable by number or letter) -- the red and green dragon tiles would otherwise differ only in color. This would make playing difficult for those who have a color vision deficiency.

Where is the wall?

Building and breaking the wall (as well as dealing and drawing from the head) are artifacts of playing at an actual table with physical tiles. The wall is therefore more of a "ritual" than a rule. It is not necessary on, as the tiles are thoroughly randomized for each game. To see how many tiles are remaining in the wall, click on the "Discards" tab in the sidebar on the right.

Connection status

You may receive a popup window indicating that "Your connection to the game was lost". This means that for some reason, MyJongg lost its connection to the server. The "Connection Status" window means that an attempt was made to rejoin the game. However, depending on how long the connection was inactive, the game may have been already closed, making it impossible to rejoin. The popup window will indicate whether the connection could be restored or not.

There are a number of reasons why this might have happened, including:

  • You are playing on a mobile device like an Apple iPad (as opposed to a laptop or desktop PC) and you closed the web browser, switched to another app, or allowed the screen to lock due to inactivity. This causes iOS to suspend the web browser to save battery life, which closes any active connections.
  • Your internet connection may have been interrupted.

Trading for jokers

  1. Select (by clicking or tapping) the tile in your hand that you would like to trade.
  2. Select the exposed joker for which you would like to trade.
  3. The "Trade Joker" button should now be enabled. Click it.

Note that you can only trade for a joker on your turn. To trade for more than one joker, simply repeat the steps above multiple times.

How do you earn points? What are the scoring rules?

Basically, the winner of the hand receives the number of points shown on the card for that hand. There are a number of bonuses and penalties, however:

  • A 2x bonus is awarded for winning with a pure hand (no jokers used).
  • A 2x bonus is awarded for drawing your own winning tile.
  • A 2x bonus is awarded for trading for an exposed joker that is used to win.
  • A 10-point bonus is awarded for winning on the last tile in the wall.
  • A 10-point penalty is charged for discarding a tile that is claimed by another player to win.

If a hand ends in a wall game (a draw due to no tiles remaining in the wall), all players receive 10 points.

What does the red lightning bolt symbol mean?

Lightning bolt

The red lightning bolt symbol next to a player's name means that they are a Premium member.

What does the thumb tack symbol mean?


The thumb tack next to a player's name means that they are the "table captain" -- they either created the table, or they are the human player who has been at the table longer than anyone else.

How do I start a table with Tile Tutor?

In order to use Tile Tutor, you must start your table using the "Start a New Table" button (not the "Just Play" button) in the lobby. When you enable Tile Tutor, scoring is automatically disabled, so you will not score any points or receive credit for any wins for games played with Tile Tutor.

Starting a table with Tile Tutor

Tile Tutor will be enabled for all players with a Premium membership who join this table. Those without a membership will still be able to join the table, but they will not be able to access Tile Tutor.

How do I use Tile Tutor at the table?

Once your Tile Tutor-enabled table has started, you can access the Tutor by opening the sidebar on the right and switching to the "Tutor" tab.

Accessing Tile Tutor

  • The "Best Sections" area looks at the number of hands in each section of the card that match your tiles and recommends the top three sections. This gives you an area of the card in which to focus.
  • The "Best Hands" area lists the top three matching hands for your tiles. The yellow number next to the hand is the point value for that hand as shown on the card. You can expand or collapse each hand by clicking on the blue plus/minus button.
  • The hands recommended by Tile Tutor do not take into account tiles that have already been discarded, so hands that can no longer be completed may be recommended.

The features of each recommended hand are as follows:

Using Tile Tutor

  • Sort Like This - This button orders the tiles in your actual hand to match this recommended hand, with needed tiles on the left and unneeded tiles on the right.
  • Matching Tiles - This shows the tiles needed to complete the chosen hand. The numbers below each tile indicate how many of that tile you have out of the total needed. Red numbers indicate that you do not have any of those tiles.
  • Match Strength - This shows the total number of matching tiles that you have in your rack as well as the number of needed singles and pairs. These numbers are important because they impact your ability to complete this hand.
  • Tile Tutor Score - This is a composite number that shows the strength your tiles toward the chosen hand. A "mah jongg" (winning) hand will have a score of 100. It takes into account the following:
    • The number of tiles in your rack that match the chosen hand
    • The number of points the chosen hand is worth (as printed on the card)
    • The number of incomplete singles and pairs (since they cannot be exposed and jokers cannot be used)
    • The number of quints (or larger) needed (since jokers must be used)
    • Whether or not the hand is concealed (since concealed hands are more difficult to complete)

Blind passing

On the last pass of each Charleston (i.e. the first left pass and the last right pass), you are allowed to pass fewer than three tiles. This is called "blind passing" (or sometimes "stealing").

To do so, simply select and pass fewer than three tiles. The game will take care of the rest -- making sure that the receiving player gets the full three tiles.

Game is frozen at "Stand By..."

I apologize if you run into this problem. I'm working on finding and fixing problems that can cause the game to become unresponsive. Unfortunately, I haven't been able to track down the cause of this particular issue yet.

If your game gets stuck, you can try clicking on the "Refresh Table" button in the "Settings" popup window.

If this doesn't work, go ahead and send me a message (using the feedback form from within the game) to let me know. Please include as many of the following details as possible:

  • What kind of device are you using to play (e.g. desktop or laptop PC, iPad)?
  • On that device, what web browser are you using (e.g. Internet Explorer, Safari, Google Chrome)?
  • Do you experience this problem when playing alone with computer players, with other human players, or does it happen in both circumstances?

Chatting with other players

To chat with other players during a game, first make sure that the sidebar on the right is open. This help article explains how to open and close the sidebar.

Once the sidebar is open, switch to the "Chat and Messages" tab. Click or tap the text box at the bottom of the tab, type your message, then click the "Send" button or press the ENTER key.

How to use private tables

Private tables allow you to play (either with friends or against the computer opponents) without your game appearing in the lobby. Players will need to be on your friends list or know a code to join.

Creating a Private Table

To create a private table, just click on the "Start a New Table" button in the lobby and check the "Create a private table" button as shown below:

You can choose to specify a secret table code that you and your friends have agreed upon in advance. If you don't specify a code, one will be generated for you by the game.

You can also optionally choose to show this table in the Lobby to any player on your friends list. This will allow them to join your private table without knowing the code.

Finally, you can also specify how many computer players (bots) you wish to have at your private table.

Sharing the Private Table Code

Once you are at the table, you should have a button labeled "Game Code" that will show you the code necessary to join the table. You can then share this code with your friends via text message, email, or some other means.

Please note that this code is specific to this table only. If you leave and/or create a new table, this code will not work.

Create private table

Joining a Private Table

If you were given a private table code by someone else, just click the "Join a Private Table" button in the lobby and enter the code you were given. You should then be taken to the private table.

Create private table

How do I use the training room?

The training room is started from the "Train" tab in the lobby. Click on the "Start Training!" button under that tab to get started. Follow the prompts on the next screen to start your training session.

The training room works by showing you a winning Mah Jongg hand from the chosen card with one tile missing. You must then choose the tile that completes that hand from the grid of tiles below.

Training Room

You don't compete directly against other players in the training room. Your "training points" are kept separately from your points earned while playing at the actual tables and can be seen on your profile page.

Why do the bots get more jokers than me? Why do I rarely receive multiple jokers?

The tiles (including the jokers) are completely random and the game does not favor computer players or humans. Every player has an equal chance of drawing jokers from the wall on their turn.

Some possible reasons why it might appear otherwise:

  • If you are playing at a table against three computer opponents, they are three times more likely to win simply because they outnumber you three-to-one (not taking relative skill into account, of course).
  • Jokers increase the chances of winning, so winning hands are naturally going to tend to contain more jokers. You see the winning hand at the end of each game, but don't see the other hands that likely had fewer jokers.
  • Games played "in real life" at an actual table where the tiles are shuffled by hand are likely not as random. This can lead to "bunches" of jokers in the wall. When you become accustomed to this joker distribution, a truly random wall can feel "wrong".

How do I save a game and resume it later?

If you are playing against bots and need to "pause" your game for some reason, there is a new "Save Game" option that appears when you click on the "Leave Table" button:

Save game button

Clicking on this button will save the game then return you to the Lobby page so that you can resume the game at a later time. On the Lobby page, you'll see a note indicating that you have a saved game:

Saved games lobby

Clicking on the "Resume Saved Game(s)" button will take you to a page that shows a brief snapshot of the game or games that you have saved, allowing you to resume or delete them:

Saved games

How do I access my stats and game history?

A complete history of your games is kept by Your Premium membership gives you access to those games, as well as statistics about your wins, losses, and hands played. To access this information, open the "Analyze" tab in the Lobby.

The "Basic Stats", "Most-Played Cards", and "Most-Played Hands" sections give you information about your performance and tendencies. The "Game History" section shows a list of months and years in which you have played. Choosing a month and clicking on the "Load Games" button will show you all games completed in that month. Clicking on a date in the resulting table will open a snapshot of that game in a new browser tab or window.

Game History

Sideways tiles

You right-click with your mouse to turn tiles sideways. Some players do this to mark tiles that they need to watch for. Right-clicking again should return the tile to normal.

Sideways tiles

There is no equivalent to right-clicking on touchscreen devices like iPads, so there is no way to turn tiles sideways on those devices.

How do I add or remove computer players from my table?

If you are playing at a table that you created (or you are the player who has been playing at the table the longest), then you can add or remove computer players from the game.

To add a computer player, click or tap the "Add Computer Player" button above your tile area and confirm when asked in the popup message. Note that if a game is currently in progress, this button will not be available.

To remove a computer player, click or tap on the arrow icon next to that player's avatar and confirm when asked in the popup message. Be aware that removing a computer player from a game in progress will end that game.

Adding friends to your friends list

The first step to adding friends is to search for them (by username or location) on the player search page. This link is located below your friends list in the lobby. Once you have found your friend, click on them in the results to open their profile page. There you should see a "Add to Friends List" button. Click that and they will be added to your list.

When your friends are playing at a table, they will be highlighted in red in your friends list (unless they have chosen not to allow this in their settings):

Active friends

To remove a player from your friends list, click on their profile picture in the friends list in the Lobby. A popup will appear containing a "Remove from Friends List" button:

Remove friend

Click this button to remove them from your list.

How do I view, update, or cancel my subscription?

You can see your subscription status, update your payment method, and cancel your subscription from the " Premium" tab on your profile page.

Manage Your Membership

Note that all sales are final and no refunds will be issued. Refunds are not offered because there is really nothing to "return" (you will continue to have access to all of the Premium membership benefits until the expiration date) and has limited customer service resources.

How do I see the other players' hands at the end of a game?

To do so, just click on the "Results" button above your tiles, then click on the "Show Previous Game" button in the popup window. You can use the list to choose either a player whose tiles you would like to see, the remaining wall tiles, or the discarded tiles:

You can return to the scoreboard by clicking on the "Show Results" button:

Return to scoreboard

Would you prefer to keep your unexposed tiles a secret? Just open the "Player Settings" window, un-check the "Allow other players to see your hand at the end of each game" box, and click "Save Changes". This change will not take effect until the next game.

Hide tiles

Why are some players highlighted in red in the Lobby?

Active Player

Players are highlighted with a red background on the Lobby page (in both your friends list and the leaderboard) when they are actively playing at a table.

Players at private tables are not highlighted in this way. In addition, players can choose to not be highlighted in their profile settings.

How can I prevent other players from seeing when I am online?

You may not wish to allow other players to see when you are actively playing at a table. There is an option to hide your playing status on the "Other Settings" tab of your account page. In addition, there is an option to hide your recent game history from other players if you do not wish them to see on what days and times you have played. Refer to the animation below to see how to enable these privacy options.

How to send feedback and bugs

Use the feedback page to report bugs or to send suggestions. They are both appreciated!

Who are you?

This is me.

I live in Oklahoma with my wonderful wife, two kids, and two dogs. I'm a software developer by day. I learned Mah Jongg a few years ago (thanks to my favorite mother-in-law) and started to work on the site in my spare time when I saw that there weren't a lot of options for playing American Mah Jongg online.


Tile images are used with permission from Yellow Mountain Imports. Their American mahjongg tutorial is excellent as well!
