Before anyone draws from the wall, before the first discard, and before the table settles into its rhythm, American Mahjong begins with a little choreography.
Three tiles move right.
Three tiles move across.
Three tiles move left.
That opening exchange is called the Charleston, and for many new players, it is the first moment the game feels slightly mysterious. Everyone seems to know where the tiles are going. Someone mentions a blind pass. Someone asks about stopping. Then someone whispers the one rule you absolutely cannot forget:
Never pass a joker.
Here is the clean version: the Charleston is the tile-passing phase that happens before regular play begins in American Mahjong. It gives each player a chance to move away from weaker tiles, notice patterns, and begin shaping a possible hand before the first discard. The National Mah Jongg League, which publishes the American version of the rules and supplies the annual Official Standard Hands and Rules Cards, identifies the Charleston as part of what distinguishes American Mahjong from other versions of the game (National Mah Jongg League, n.d.).
The Charleston Order
The Charleston is easiest to learn when you think of it as two possible rounds, followed by one optional final exchange.
The First Charleston is required:
-
Pass 3 tiles to the right
-
Pass 3 tiles across
-
Pass 3 tiles to the left
Then the table decides whether to continue.
The Second Charleston is optional and only happens if everyone agrees:
-
Pass 3 tiles to the left
-
Pass 3 tiles across
-
Pass 3 tiles to the right
After that, players may do a Courtesy Pass with the person across from them. This final pass can be 0, 1, 2, or 3 tiles, but both players must agree on the number.
First: right, across, left. Second: left, across, right. Courtesy: across.
That is the whole map.
What Is the Point of the Charleston?
The Charleston is not just housekeeping. It is the first real decision-making moment of the hand.
At the start, your rack is usually messy. You may see a pair, a possible suit direction, a few flowers, or nothing that feels especially promising. The Charleston helps you move away from tiles that do not fit while watching what comes back to you.
The goal is not to find the final hand immediately. The goal is to stay open long enough to see what the tiles are telling you.
A good Charleston does not lock you in too early. It keeps your best options alive.
Before passing, glance at the current American Mahjong card and look for two or three possible hand families your rack could become. If you only chase one hand too soon, the Charleston can become risky. You may pass away a tile that later turns out to be exactly what you needed.
For newer players, the complimentary American Mahjong Cheat Sheet can be helpful. It gives you a quick visual reference for tile types, hand patterns, and common beginner confusion without slowing down the table.

The Blind Pass
The blind pass is one of the Charleston rules that sounds more complicated than it is.
During the final pass of each Charleston round — First Left or Second Right — you may pass along one, two, or three tiles from the group just passed to you without looking at them.
That matters because sometimes your rack is strong and you do not want to break it up. Instead of giving away useful tiles from your own rack, you can move along unknown tiles from the incoming pass.
The key rule is simple:
If you pass blind, you cannot look at those blind tiles first.
A blind pass is not a peek-and-decide situation. It is a way to fulfill the pass while protecting a hand that is already developing.
Can You Stop the Charleston?
Yes, but only after the First Charleston is complete.
The first three passes — right, across, left — are mandatory. After that, any player may stop the Charleston before the Second Charleston begins. You do not need a dramatic explanation. A simple “I’d like to stop” is enough.
Stopping can be smart when your hand is already taking shape and you do not have enough safe tiles left to pass. Continuing just because everyone else seems eager can accidentally force you to break apart pairs, flowers, or flexible tiles that could still matter later.
Do not treat the Second Charleston as automatic. Treat it as a choice.
The Courtesy Pass
After the Charleston ends, the two players sitting across from each other may do a Courtesy Pass.
This pass is optional. The number can be 0, 1, 2, or 3 tiles. Both players exchange the same number, and the number is usually determined by the player who wants to pass fewer tiles.
If you have nothing useful to give, say so. If you only want to exchange one tile, that is perfectly valid.
The Courtesy Pass is small, but it can matter. One clean exchange can remove a tile that does nothing for your rack — or bring in the tile that gives your hand direction.
The Joker Rule You Cannot Forget
In American Mahjong, jokers are powerful because they can help complete certain groupings, but they are not treated like ordinary passable tiles. The NMJL notes that American Mahjong uses more tiles than other versions, notably the joker, and uses the annual card of standard hands (National Mah Jongg League, n.d.).
During the Charleston, the practical rule is:
Never pass a joker. Not in the First Charleston. Not in the Second Charleston. Not in the Courtesy Pass.
If a joker is passed by mistake, it should be returned and replaced with a proper tile. For beginners, this is one of the most common errors because a joker may not look immediately useful at the beginning of the hand. Keep it anyway. A joker that feels irrelevant during the Charleston may become valuable once your hand takes shape.
For a deeper look at how jokers work once regular play begins, our guide to jokers in American Mahjong can help clarify where jokers are useful, where they are limited, and why they matter so much.
What Should You Pass?
Start with tiles that have the least connection to your possible hands. A lonely tile in the wrong suit, an unmatched number that appears nowhere on the card for your direction, or an isolated honor tile may be easy to release.
Be more careful with:
-
Pairs, because they are hard to rebuild
-
Flowers, because many hands need them
-
Flexible number tiles, because they may work in more than one hand
-
Jokers, because they should never be passed
A good Charleston is part strategy, part restraint. You are not only asking, “What do I dislike?” You are also asking, “What might I regret giving away?”
If you are playing on a hard surface, a Mahjong mat can also make the passing rhythm feel smoother and more organized. The point is not decoration; it is giving the tiles a defined surface so the table feels easier to manage.
Common Charleston Mistakes
The biggest mistake is passing before looking at the card. Even a quick scan gives your hand more direction.
Another common mistake is committing to one hand too early. If the tiles are still uncertain, keep two or three possibilities alive through the First Charleston.
Players also forget to watch what comes back. If you keep receiving similar tiles, that may tell you what other players are discarding — and what they probably are not building.
The quietest mistake is emotional: rushing because everyone else seems faster.
The Charleston rewards calm players.
Take a breath, read your rack, protect your flexible tiles, and remember that the game has not truly begun yet.
The Simple Charleston Summary
The First Charleston is required: right, across, left.
The Second Charleston is optional: left, across, right.
The Courtesy Pass is optional: 0 to 3 tiles across.
The blind pass is allowed only on the final pass of a Charleston round.
Jokers are never passed.
Once you understand that structure, the Charleston stops feeling like a memorization test. It becomes what it was meant to be: the first strategic conversation between your rack, the card, and the table.
The best players are not simply passing tiles away.
They are listening early.
