10 Beginner Mistakes to Avoid in Your First American Mahjong Games

American Mahjong setup on a white mat with lined sections, four green racks holding walls of white tiles, and the 2025 National Mah Jongg League card displayed on the table.

Starting American Mahjong can feel overwhelming—there’s the National Mah Jongg League card to learn, the Charleston, new terminology, and even unspoken table etiquette. Mistakes are part of the journey, but knowing the most common ones will help you feel more confident, enjoy the game more, and earn repeat invitations to play.

Here are 10 mistakes nearly every beginner makes—and how to avoid them.


Mistake #1: Ignoring the American Mahjong Card

The National Mah Jongg League card is your roadmap. Beginners often skim it and then feel lost mid-game. Every hand has strict requirements, so study it carefully before playing. Notice which hands use multiple suits, which require pairs, and which are consecutive. The card changes every year, so even experienced players need to refresh. Don’t skip the rules on the back—they explain essentials like Charleston passes, how to call tiles, and joker exchanges. These details prevent confusion and help you play with confidence.


Mistake #2: Spreading Tiles Too Thin Instead of Choosing a Hand

Beginners try to play too many hands at once. After the Charleston, commit to one or two hands maximum. This focused approach gives you a real chance of making Mahjong instead of ending up with a scattered rack.

Mistake #3: Passing Too Quickly in the Charleston

The Charleston sets up your entire game, but beginners often rush. Beginners should aim to complete the Charleston in four minutes. Take time to consider which tiles truly don’t fit your potential hands. Also, remember basic etiquette: don’t pick up until everyone is ready, and always ask if the table wants to continue before the second Charleston. This keeps the pace fair and friendly.


Mistake #4: Confusion About the Charleston Blind Pass and IOU Rule

The blind pass (passing tiles without looking) confuses many beginners. During the final pass of each round (first left, last right), you may pass tiles blind—without looking at what’s just been passed to you. Don’t panic, just follow the rule. And remember, patience and courtesy during Charleston exchanges keep the table running smoothly.


Mistake #5: Throwing Away Tiles Without Watching Opponents

New players often discard tiles carelessly. Always watch what others pick up and expose—those are clues to their hand. Avoid feeding someone’s Mahjong by tossing flowers or numbers they clearly need.


Mistake #6: Forgetting About Joker Exchanges and Misusing Them

Jokers are powerful, but beginners often misuse them. Remember:

  • You can only exchange a natural tile for an exposed joker.
  • Exchanges must be done hand-to-hand, never on the rack or table.
  • A discarded tile can never be used for a joker exchange.

If someone discards a tile that could have been exchanged, don’t point it out. It might have been a strategic move—or simply a mistake. Either way, commenting is poor etiquette.


Mistake #7: Skipping Table Etiquette

American Mahjong is as much about manners as strategy. A few key points:

  • Never touch another player’s rack.
  • Keep your hands clean.
  • Be polite when exchanging jokers (hold out your tile and say “please, may I have your joker?”).
  • Don’t sigh, drum fingers, or rush slower players.
  • Always congratulate winners and allow them their moment.

Good etiquette keeps games pleasant and ensures you’ll be invited back.


Mistake #8: Holding Onto “Favorite” Tiles That Don’t Fit

Many beginners cling to flowers or lucky numbers even when they don’t fit their chosen hand. Let go of personal favorites—play what the card calls for, not what you like best.


Mistake #9: Avoiding Help From Experienced Players

Don’t let pride stop you from asking questions. Most seasoned players love helping beginners who show genuine interest. Just be mindful to ask between games, not during play, to respect the pace of the table.


Mistake #10: Taking Mahjong Too Seriously Instead of Having Fun

Yes, Mahjong requires skill and focus—but it’s also a social game. Don’t get discouraged by mistakes or losses. Laugh, learn, and enjoy the community that makes Mahjong so special.


Final Thoughts: Learn the Rules, Respect the Table, Enjoy the Game

Every beginner and even experienced players make mistakes, but understanding both the rules and the etiquette will help you feel more confident and make games more enjoyable for everyone. With practice, patience, and good manners, you’ll grow from a hesitant beginner into a player people love having at their table.
