Choosing a hand after the Charleston means looking at the 13 tiles on your rack (14 if you are East) and deciding which one or two lines on the card are worth chasing. The goal is not the perfect hand. The goal is a practical one, plus a backup.
The last pass is done, your rack looks different from a few minutes ago, and the table goes quiet. This is where many first hands quietly fall apart, because beginners go looking for the best-looking line instead of the line their tiles actually support.
Key takeaways
- Sort your rack first, then count pairs, jokers, flowers and your longest suit.
- Look for card lines that already match several tiles you hold, not lines that simply look valuable.
- Keep two lines in play, so one discarded or exposed tile does not end your hand.
- Switching lines early costs little. Switching after you have exposed sets costs a lot.
- Your plan can change every turn. Treat it as a working guess, not a promise.
Step 1: take stock of your rack
Before you open the card, sort your rack. A sorted rack shows you things a jumble hides. If you have not built the habit yet, our guide to the 60-second rack sort walks through it.
Once the tiles are in order, count these four things:
- Pairs. Pairs are the building blocks of many lines, and jokers can never complete them.
- Jokers. Every joker you hold is yours to keep, because jokers can never be passed in the Charleston or the courtesy pass.
- Flowers. On the card, F stands for any flower, and all eight flowers are interchangeable.
- Your longest suit. Do you hold more dots, bams or craks?
Say it quietly to yourself: “Two jokers, two pairs, three flowers, mostly bams.” That sentence is your starting inventory.
Step 2: find lines that already fit
Now open the card. If you are still learning how it is laid out, start with what the mahjong card is and how its colors stand for suits.
Scan for lines that ask for things you already hold. A line that needs groups you already have pieces of deserves more attention than one that needs groups you have nothing toward, however attractive its value looks. Value only matters if you can finish the hand.
Remember how the colors work
On most lines, the colors stand for suits, not tile colors, and you choose which suit goes with which color. So one line can fit your rack in more than one way. Some lines carry notes that override the colors, so read the small print. Winds, flowers and zeros have no suit.
Check the C or X
Each line is marked C (concealed) or X (exposed allowed). Concealed lines are generally worth more than comparable exposed lines, but a concealed hand means no exposures, so you cannot call discards to complete sets along the way. If your rack is thin on tiles that already pair up, an X line that lets you call may be more realistic. Our explainer on concealed and exposed hands goes deeper.
Step 3: shortlist two lines
Pick two lines, not one. If a key tile for the first line is discarded or exposed by someone else, you still have somewhere to go. Choosing a single line this early locks you in before you know what the wall will give you.
It helps if the two lines share a few tiles you already hold, so most of your rack stays useful whichever way you go.
Think about jokers too. They stand in only for tiles in groups of three or more, never in a pair or as a single, so a line built mostly from pairs gets no help from them.
A worked example with made-up lines
Imagine a rack of 13 tiles after the Charleston: one joker, two flowers, a pair of North winds, a 4, 5 and 6 of bams, two 8 of dots, one red dragon, one 2 of craks and one 9 of craks.
Now imagine two invented lines. These are not from any real card:
- Made-up line A: a group of flowers, a group of winds, and two suited groups.
- Made-up line B: several pairs in different suits, plus one larger group.
Line A looks promising. You hold two flowers plus a joker, which could help fill a flower group. You hold a pair of North winds that could grow into a group. The bams might become one of the suited groups. Line B asks for several pairs, and you clearly hold only two, one of them the winds. Your joker would not help with any of those pairs.
So you shortlist line A first, with a second line that also uses the North pair and the flowers as a backup. If other players expose two North winds, you know the rest are scarce and can switch early.
Step 4: stay flexible, then commit
In the first several turns, discard tiles that fit neither line. Tiles that serve both lines are the last ones to let go.
- Watch the table. What others discard and expose tells you which tiles are scarce. If most of the tiles you need are already gone, change lines.
- Think before you call. Calling a discard puts a set on display. Exposed sets count toward your 13 tiles and stay on view, which narrows your options. For the timing rules, see calling a discard.
- Switch while it is cheap. A switch after two or three turns costs you very little. A switch after you have exposed a set may cost you the hand.
If your group plays a second Charleston
The second Charleston is optional. It happens only if all four players agree, and any player can decline. If your table plays one, hold your shortlist loosely until it is over, because the extra passes can change your rack a lot. The courtesy pass between the two players sitting across from each other can do the same. For the details, read the second Charleston and the courtesy pass.
If you are East
East starts with 14 tiles and discards first. That first discard is a chance to let go of a tile that fits neither of your lines. Pick it with your shortlist in mind.
Common mistakes
- Falling in love with a line. If a line is worth a lot but needs tiles you do not have, it is a wish, not a plan.
- Keeping only one line. One line means one point of failure.
- Ignoring discards. If you never look at the table, you may chase a tile that three other players have already thrown away.
- Drifting between two lines. If your hand ends up almost line A and almost line B, it may match neither. A winning hand must match a line exactly, including suits, groups and the C or X status.
Try it at your next game
When the Charleston ends, take 30 seconds before your first turn. Sort your rack, say your inventory to yourself, and pick your two lines. After a few turns, notice whether you stayed on your first line or switched, and why. Do this for three games and you will start to feel which tiles are worth holding.
A line reader card can help here, since it lets you cover everything on the card except the line you are studying. We sell a 4-pack of line reader cards in our mahjong accessories collection. The yearly hand card is not included, so you will still need your own from the National Mah Jongg League.
Frequently asked questions
How many lines should I keep in mind after the Charleston?
Two is a good number for a beginner. One is too risky, and more than three is hard to track while you also watch the discards. Narrow down as the hand develops.
Can I change my hand after I have picked a line?
Yes. Nothing is declared in advance, so you can change your plan on any turn. The practical limit is exposures: once a set is on display it stays there, so switching is only realistic if the new line can use it.
What should I do if my rack fits no line well?
Choose the line with the most tiles you can use, keep your jokers and any pairs that overlap, and discard the tiles that fit nothing. Many hands start out unpromising and improve with a few good draws.
Should I always aim for the highest-value line?
Not at first. Value only counts if you win. A modest line that your tiles support often beats an impressive one that needs tiles you do not hold, especially while you are still learning.
Are concealed lines a good idea for beginners?
They can be, if your rack already holds many of the tiles you need. If you expect to rely on calling discards, an X line is usually more forgiving, because you are allowed to expose sets.
