Mastering Charleston Decision-Making in American Mahjong

Three Mah Jongg tiles stacked in a pyramid formation to represent the second left pass during the Charleston phase in American Mahjong.

Build smarter hands from the start, adapt quickly, and sharpen your game with strategy and observation.


Why the Charleston Matters

The Charleston is a series of mandatory tile passes at the start of the game and sets the tone for your entire hand. It can feel chaotic, especially for new players, but with the right mindset and a little practice, it becomes a powerful opportunity.

Great Charleston decisions = stronger hands = more wins.


Know the Card, Not Just the Hands

Before making good decisions, you need to understand the structure of the Mah Jongg card:

  • Learn the difference between fixed vs. flexible hands
  • Understand categories: 2468, Consecutive Run, 369, Winds/Dragons, etc.
  • Read the parentheses — they often clarify how a hand must be built
    (Don’t skip this! Misreading them is a common cause of dead hands.)

Tip: You don’t need to memorize every hand, but you should recognize patterns and categories at a glance.


What Is the Charleston?

The Charleston consists of three rounds of tile exchanges between players. Its main purpose:
Build a stronger hand by collecting tiles that support a recognizable NMJL pattern.

Your goals during the Charleston:

  • Identify your strongest direction
  • Build around any multiples (pairs, pungs, kongs)
  • Stay flexible and observe what others pass

Step-by-Step: How to Make Strong Charleston Decisions

StepWhat to DoWhy It Helps
Start with Your MultiplesBuild around any pairs or pungs you start withMultiples often form the core of winning hands
No Multiples? Find Your Strongest Suit or CategoryCount suits, sequences, or categories you have the most tiles inNarrow down your possible hand directions
Don’t OvercommitUse early passes to gather possibilitiesFlexibility gives you room to pivot later

Let the Tiles Lead — Not Just Your Preferences

During the Charleston: Reorganize Often

Every time you receive tiles, rearrange your rack:

  • By suit
  • By number
  • By card section

This can reveal new possibilities you hadn’t considered and identify spots where jokers could substitute effectively.
Even “junk” tiles should be racked first to avoid giving away visual “tells” that signal disinterest.


Think in Terms of Patterns and Overlap

  • Don’t chase an exact hand too early.
  • Focus on overlapping tiles that work in multiple sections.
  • Consider year hands that use less-common combinations (e.g., 2 and 5 in 2025).

 Strategy for 2025 NMJL Card

If you have a lot of: Look for hands in this category: 
2s and 5s Year (2025)
Even numbers 2 4 6 8 
Odd numbers1 3 5 7 9  Pick either 1-3-5 or 5-7-9 for clarity.
The same number Like Numbers, Quints, or Consecutive Run
The same suitConsecutive Run, (in evens) 2 4 6 8, or  (in odds) 1 3 5 7 9 
WindsWinds and dragons 
3s, 6s and 9s3 6 9 
3 or more jokers Quints 
No jokers Singles & pairs

Don’t Judge Your Hand Too Early

Your first 13 or 14 tiles if you are East are just the beginning.
If you complete both Charlestons and the courtesy pass, you’ll see up to 21 new tiles!

Stay open to pivoting and reassessing direction based on new tiles.


Watch for Overlooked Hand Types

  • Addition/multiplication hands are often skipped, but can be great pivot options. If your tiles don’t support a major category, don’t overlook these “backup” hands

Prioritize Pattern Compatibility

  • Each tile in your hand should support a clear goal:
    Ask yourself, “Does this tile move me closer to a valid hand from the card?”
  • Let go of “pretty” or uncommon tiles that don’t fit your strategy.
    Keep your rack focused, flexible, and aligned with NMJL patterns.

Smart Pair Passing

  • Don’t hang on to pairs that don’t help your hand.
    Break them up early to free space and improve your passes.

Strategy: Observing What Others Pass

Charleston strategy isn’t just about your hand — it’s about reading the table.

Why Observation Matters

  • Validate your hand direction
  • Avoid passing helpful tiles to opponents
  • Predict others’ categories and play defensively

 Watch the “Two Lefts”

The two left passes from your right-hand opponent often reveal what they’ve ruled out:

  • Entire suit passed = likely not playing that suit
  • Winds/dragons = skipping special hands
  • Rejected pairs

Reverse the First Right

Remember what you received in the first right?
If it’s unhelpful, consider passing it back on the first left — it’s strategic, cheeky, and allowed.


Read the Room: Reactions & Behavior

Facial expressions and reactions can reveal:

  • Frustration = you blocked their direction
  • Surprise or delight = you may have helped them
  • Body language = “tells” about how good their pass was

Joker & Tile Value Strategy

  • Save valuable tiles (flowers, dragons, winds) even if they don’t help yet as they may be used in joker exchanges.
  • If your hand relies on pairs, and you have lots of jokers, consider switching to a more joker-friendly hand.
  • Don’t cling to tiles just because they’re “rare” — stick to what works

Get Out of Your Comfort Zone

  • Don’t play the same hands over and over.
  • Try Quints, Singles & Pairs, or less common categories.
  • Keeps opponents guessing and sharpens your overall skill set

Pro Tip: In casual play or online, challenge yourself to try a new category each game.

Pick-and-Discard Phase: Stay Observant

Once the Charleston ends, the real game begins — but your attention should stay sharp.

Watch for:

  • Frequent discards = unwanted suits or numbers
  • Repeat discards = safe to pass
  • Exposures = clues about opponents’ hand categories

If you’re not getting what you need, consider pivoting before it’s too late.


 Practice Makes Progress

The more you play, the faster your decisions become. But you can accelerate improvement by:

 Watching Charleston practice videos
Doing pattern recognition drills
Talking through your tile choices with other players


Final Takeaways: Smart Mah Jongg Strategy

✔️ Let the tiles guide you — not a fixed plan
✔️ Reorganize your hand frequently
✔️ Observe what others pass and expose
✔️ Stay flexible and ready to pivot
✔️ Practice regularly to sharpen instincts


With consistency, observation, and a flexible mindset, you’ll find Charleston decisions and your overall Mahjong game improving dramatically.
