Hey — I’m Connor, your resident mahjong geek.
If you’ve been playing American Mahjong and kept hearing about “the card,” “the 2025 edition,” or “hand patterns,” this article is for you.
The National Mah Jongg League (NMJL) card is the central blueprint of American Mahjong. Mastering it unlocks everything — from smart hand choices to confident calls and real wins.
If you don’t have the 2025 card yet, you can practice the new patterns directly on I Love Mahj — the leading platform for learning and playing American Mahjong online, fully aligned with NMJL rules.
In this guide I’ll walk you through what the 2025 card is, how to read it, how to use it in gameplay, and the strategic mechanics that make it far more than just a cheat sheet.
Why the Card Matters
In American Mahjong, you’re not simply trying to build any winning hand — you must build one of the exact patterns listed on the current NMJL card. If your hand doesn’t match, you don’t win (even if it looks “good”).
The card becomes both your legal map and your strategic roadmap. Because it changes every year, staying current matters.
Use an old card, and you risk invalid hands, confusion, or worse — getting laughed out of the club.
💡 Tip: You can always double-check the 2025 card layout and updated hands using the I Love Mahj online practice table, which automatically applies the correct year’s rules.
Over time, you’ll stop looking at the card and start feeling tile paths. That’s the hallmark of a confident American Mahjong player.
What You’ll See on the Card
Here’s a breakdown of the key elements on the 2025 card and what each tells you:
- Hand patterns: Each line shows a precise combination — e.g., “2 0 2 5” (for the year) or “Any Nine & Any One”. These are your target blueprints.
- Color-coding: On the printed card, different color backgrounds or tile-icons signal how many suits are allowed. One colour = one suit; two colours = two suits; three colours = three suits. It’s bizarre until you’ve seen someone mis-play because they ignored the colour rule.
- Parentheses, asterisks & footnotes: These contain important instructions: “Jokers not allowed,” “Exposed only,” “No Flowers,” or “Contains White Dragon as wild for this year.”
- Suit icons and examples: Some cards include small tile images to illustrate how the pattern might look in play.
- Annual edit flag: Towards the bottom you’ll often see a line like “2025 Edition” or “Valid Jan 1 2025 – Dec 31 2025” to show you’re using current material.
Key Categories on the 2025 Card
The card is organised by themed categories. Each has implications for how you play. Here are major categories and what to watch:
• “Year” Hands
These use the digits of the year: for 2025, you’ll see patterns like 2-0-2-5 (where 0 = White Dragon or similar substitution). These are often solid starters for beginners because they’re familiar yet still require focus.
• Like Numbers / Odds / Evens
Hands like “2-4-6-8” or “Any Odd/Nine” show up. These let you play patterns based on tile values rather than suits. Useful when you start with mid-value tiles.
• Consecutive Runs (Chows) Across Suits
For example: a run of 4-5-6 in one suit and 6-7-8 in another. These require you to keep eyes on two suits and manage dumpster turfs (discard piles) accordingly.
• Winds & Dragons
These hands lean heavily on honours (EAST, SOUTH, WEST, NORTH winds; RED/WHITE/GREEN dragons). Because honours are scarce and often contested, these categories are higher risk/higher reward.
• Singles & Pairs Only
Some patterns demand only pairs (no pungs) or require no jokers. They’re complex and often require you to keep many tiles rather than expose early. Great for advanced players who want control.

How to Read the Card Like a Pro
Here are actionable steps you can adopt immediately:
- Quick scan before the deal – glancing at the list helps your brain starting forming possible paths.
- Pick 1–2 target patterns – based on your initial rack and early picks, choose your primary target and a backup.
- Watch the colour rule – decide how many suits you’ll use. If the pattern is one colour, stick to one suit.
- Check for restrictions – before you expose anything, look at the footnotes: Is the pattern exposed? Jokers allowed? No Flowers?
- Be ready to pivot – if your draw is poor, switch to backup pattern rather than forcing the unlikely. The card is your guide, not your trap.
Connor’s tip: I often keep a small sticky-note beside me reading: “Colour = suits. Check footnotes. Pick backup early.” It keeps me grounded, especially late in the game.
What’s New in 2025?
Every year the NMJL card includes updated patterns, removed patterns, and tweaks to keep the game fresh and balanced. For 2025 expect:
- A handful of retired patterns from 2024 — if your club still uses those, you’ll throw invalid wins.
- New higher-difficulty patterns aimed at experienced players (e.g., more single-tile/single-suit restrictions).
- Subtle tweaks in Joker rules for specific patterns (some will say “No Jokers” or restrict to only one).
- New graphics or layout that might throw off your muscle memory if you’re used to the old card format.
Mastering the 2025 patterns early gives you a huge advantage — most players take 50–100 hands to adjust.

Strategy: Using the Card to Your Advantage
Here are deeper strategic insights:
- Entry-level pattern pick: Early in the game, pick a pattern you can realistically reach from your rack. Holding out for a top-tier pattern can kill momentum.
- Joker economy: Treat jokers like currency. Use them when you need them, not just because you can. Some 2025 patterns limit their use – know which ones.
- Discard early, plan late: The card gives you targets. Discard tiles that don’t feed any target. It reduces noise in your rack.
- Trap defence: Since everyone at the table can refer to the same card, your opponents can guess your hand. Use mis-direction: sometimes hold a “bad” tile to fake your target.
- Pivot speed: If after 3–4 draws you’re nowhere near your target, shift to your backup pattern. The card is dynamic, and you should be too.
Common Pitfalls & How to Avoid Them
❌ Ignoring the color rule
❌ Using jokers too early
❌ Missing “No Flowers” or “Exposed only” notes
❌ Forcing hard patterns with poor tiles
❌ Playing with last year’s card
Keep your play sharp — and your card current.

FAQs: The 2025 Card Edition
Q: Do I have to use the 2025 edition?
A: If your club mandates it, yes. Some casual groups allow older cards, but you’ll reduce your winning chances and increase confusion.
Q: Can I build any pattern on the card, or only the ones I aim for at the start?
A: You can build any pattern on the card – but you’ll save time and frustration if you focus on 1–2 based on your rack and draws.
Q: What happens if I expose a pattern that isn’t valid on this year’s card?
A: You’ll get caught. Either you’ll be forced to “call off” your win or the club may enforce penalties or loss of point value. Always verify.
Q: Do Jokers work the same in every pattern?
A: No. Some patterns say “No Jokers” or “Max 1 Joker”. Always check the footnote. Using a Joker in a banned pattern invalidates your hand.
