How to Practice the 2027 NMJL Card (and When Apps Get It)

The short version: the 2027 NMJL card hasn’t been released yet, so nobody can practice its hands today. Not an app, not a teacher, not a website. The League usually mails the new card in late March or early April. See when the 2027 card comes out for the details.

That doesn’t mean there’s nothing to do. Most of what makes a strong player carries over from one card to the next, and the players who pick up a new card fastest in April are the ones who kept playing all winter.

What Carries Over From Card to Card

The hands change every year. Almost everything else doesn’t:

• The rules. Calling, exposures, Joker exchanges, dead hands, and scoring work the same way every year. Our American Mahjong rules guide covers them step by step.
• The Charleston. Deciding what to keep and what to pass is a skill you build over many hands. See our Charleston guide.
• Joker play. When to hold a Joker, when to use it, and when to redeem one from an exposure. See Jokers in American Mahjong.
• Reading the card’s notation. Colors, suits, and the X and C markings don’t change. See how to read the NMJL card.
• Defense. Reading exposures and discards to avoid feeding someone else’s win.
• The sections. The card’s categories, like 2468, Like Numbers, 13579, and Singles and Pairs, tend to return year after year even as the hands inside them change.

What to Do Before the 2027 Card Arrives

Now through winter: keep playing the 2026 card. Every hand you play sharpens your Charleston, your Joker sense, and your defense, and none of that resets in April.

In late December or January: order your 2027 card as soon as the League opens orders. Early orders tend to be mailed first.

In March: make a plan with your group for when you’ll switch. Most groups start using the new card once everyone at the table has one.

When Practice Apps Get the New Card

No app can have the new hands before the League releases them. After release, apps have to add the new card and ship an update. In 2026, practice apps added the new hands anywhere from late March to late April.

A few things to know:

• You still need your own printed card. The card is copyrighted. Apps generally won’t reproduce it, and the official NMJL Online game says outright that it doesn’t show the card.
• Update your apps in April. New cards usually arrive as app updates, so turn on automatic updates or check the App Store once your printed card arrives.
• Some apps let you choose the card year. That’s handy in the weeks when half your group has the new card and half doesn’t.

Mahj Parlour will add the 2027 card in an app update after the League releases it. It already lets you choose which card year you play, so you can stay on the 2026 card until your group is ready to switch. If you’re comparing options, our guide to the best American Mahjong apps for iPhone covers the main choices.

How to Learn a New Card Fast

Once the 2027 card is in your hands, here’s how to get comfortable with it quickly.

1. Read the Whole Card Once, Slowly

Before you play a single hand, read every section from top to bottom. Note which sections feel familiar and which hands look new. Compare it with your 2026 card side by side; seeing what changed is faster than learning everything from scratch.

2. Start With the Sections You Know

Most players have a few favorite sections. Start there. Getting comfortable with a handful of hands you’re likely to play gives you somewhere to go when your tiles are ambiguous.

3. Play a Lot of Hands, Quickly

Nothing replaces repetition. Short practice games against bots let you see dozens of starting hands in an evening, which is where you learn which card hands your tiles actually point toward. Look at your tiles after the deal and ask which two or three hands they could become before you start passing.

4. Pay Attention During the Charleston

The Charleston is where a new card really gets learned. Every pass forces you to decide which hands you’re keeping open. After each game, look back at what you passed and whether a different hand was hiding in your tiles.

5. Take a New Card Class

Many teachers and clubs run new-card classes each spring. Walking through the card with a teacher and other players is one of the fastest ways to see how experienced players think about the new hands.

6. Bring It Back to the Table

Practice is for the time between game nights, not a substitute for them. Take what you’ve learned back to your group, and compare notes on the hands everyone is chasing.

Where to Practice

• Your regular game. The best practice is still four people around a table.
• A new-card class or open play. Local teachers, community centers, and clubs often host them in April and May.
• A practice app. Mahj Parlour lets you play against bots with hints when you’re stuck, start private tables with your own group, or match with other players online. Its free lessons cover the rules and how to read the card if you’re rusty.

The 2027 card isn’t here yet, but the players who start April ready are the ones who kept playing through the winter.
