The Charleston: How to Pass Tiles in American Mahjong

The Charleston is the tile exchange that opens every hand of American mahjong. Before anyone discards, the four players pass tiles to each other in a fixed order, three at a time, to shape their hands toward a line on the card. New players often find it the most confusing part of the game, and experienced players say it is where many hands are won or lost. This guide walks through each pass, the optional parts, and a simple way to choose the three tiles you give away.

Why the Charleston exists

In American mahjong you can only win with a hand that exactly matches one of the patterns on the card, and there is no chow: you can't claim a discard to finish a run. That makes the deal much more important than in Chinese styles. The Charleston gives every player a chance to trade away tiles that don't fit any hand they might build and to receive tiles someone else doesn't want. It also sets the social rhythm of the table: everyone passes at the same time, so nobody waits long.

Before you pass: pick your candidates

Sort your 13 tiles (14 if you are East) by suit and by number, set the flowers and jokers aside, and look at the card. You are not choosing your final hand yet. You are looking for two or three families your tiles lean toward, such as even numbers, 369, like numbers or a run of consecutive numbers.

A quick way to read a hand:

• Count evens (2, 4, 6, 8) against odds (1, 3, 5, 7, 9).
• Look for pairs and pungs you already hold: they anchor a pattern.
• Note which suits are strongest. Many patterns use two or three suits in fixed roles.
• Count flowers. Several families need two, three or even five of them.

Once you have candidates, every tile that fits none of them is a passing tile.

The first Charleston (required)

Every hand starts with the first Charleston. All four players take part.

1. Pass right. Put three tiles face down and slide them to the player on your right. Pick up the three tiles from the player on your left only after you have passed.
2. Pass across. Pass three tiles to the player sitting opposite you.
3. Pass left. Pass three tiles to the player on your left. This is the first pass where you may pass blind.

Passing right first can feel backward if you have played other games, but it becomes automatic quickly. A useful memory aid is "right, across, left": the tiles travel around the table and come back toward you.

The blind pass

On the last pass of the first Charleston you may pass on one, two or three of the tiles you are about to receive without looking at them, in place of tiles from your hand. Players use a blind pass when every tile in their hand is useful and they would rather gamble on unseen tiles than break a pair. If your hand already has a clear direction, you rarely need it. If you are still far from every pattern, a blind pass is a way to keep your good tiles and let luck do the work.

The vote on a second Charleston

After the first Charleston, any player may ask for a second one. It only happens if all four players agree. A single "no" stops it.

Say yes when you are still far from every hand on the card. Say no when you are close to a pattern and don't want to risk passing a useful tile, or when you have already committed to a hand that needs specific tiles.

The second Charleston (optional)

The second Charleston runs in the opposite order:

1. Pass left.
2. Pass across.
3. Pass right. A blind pass is allowed again on this last pass.

The second round is where good hands become very good: by now you usually know your target, so you can pass with confidence and hope to receive the last tiles you need.

The courtesy pass

Finally, the two players sitting across from each other may make a courtesy pass of zero to three tiles. Each player says how many they would like to exchange, and the smaller number is used. If either player says zero, there is no exchange. The courtesy pass is the last chance to trade a lone tile for something useful.

What to pass: a simple method

The strongest beginner rule is: pass tiles that none of your closest hands uses. In order of preference:

1. Tiles no candidate uses. A lone wind when you are building numbers, an odd tile in an even hand, a third suit you can't use.
2. Loners over pairs. A single tile is less likely to become a group than a pair you already hold.
3. Spare copies. If your hand needs a pair of 4s and you hold three, the third 4 is cheap to give up.

And a few firm rules:

• Never pass a joker. It is against the rules, and a joker is the most valuable tile in the game.
• Think twice about flowers. Many families use them, so a flower is often worth keeping until you know your target.
• Don't pass a tile you just received if it fits. It is tempting to send back what came to you, but a tile that helps your candidate hand should stay.

Watch what comes to you

The tiles you receive tell you something. If the player on your right keeps passing you even numbers in one suit, they are probably not building an even hand in that suit. Good players use this information later to choose safer discards.

A worked example

Suppose you are dealt 2, 2, 4, 4, 6 and 8 in craks, a flower, a 3 and a 7 of dots, the North and West winds, and a 1 and a 9 of bams. Evens in craks stand out: you already hold two pairs and the start of a run of evens. The dots and bams don't fit, and the winds are loners.

• Right: pass the North wind, the West wind and the 1 bam. None of your candidate even hands uses them.
• Across: say you received a 4 and an 8 of craks. Keep them. Pass the 3 dot, the 7 dot and the 9 bam.
• Left: now you hold three 4s, two 8s, two 2s and a 6 in craks. Pass the least useful three tiles you have left, or pass blind if every tile helps.

This is the exact situation in the first Charleston lesson of our Mahjong Coach, where the coach marks the three tiles to pass at each step and explains why.

Common mistakes

• Passing too early in the direction of a single hand. Keep two or three candidates through the first Charleston. It costs little and saves hands.
• Breaking pairs to keep loners. Pairs are hard to make. Loners are easy to replace.
• Forgetting the order. Right, across, left for the first Charleston, and the reverse for the second.
• Voting yes by habit. A second Charleston helps a weak hand but can cost a strong one a key tile.

Practice the Charleston

The fastest way to get comfortable is repetition. At the Mahjong Coach's American table, the coach suggests three tiles to pass at every step with a short reason for each, advises you on the vote for a second Charleston, and shows the three practice patterns you are closest to. After the hand, the review lists each of your passes next to the coach's suggestion so you can see where you differed.
