American Mahjong Charleston Rules, Explained Simply

The Charleston is the part of American Mahjong that confuses new players the most, and it is also the part that makes the game so good. It is the round of passing tiles that happens right after the deal, before real play begins. Think of it as everyone quietly trading away what they cannot use and reaching for what they can.

Here is how it works, without the jargon.

Why the Charleston exists

When the tiles are first dealt, your hand is usually a mess. The Charleston gives everyone a few chances to pass along tiles they do not want and pick up better ones. By the time it ends, most folks have a real direction for their hand.

The passing order at a glance

The first Charleston: three passes

The first Charleston is required, and it is three passes in a row. Each pass is three tiles:

1. Pass right. Choose three tiles you do not want and pass them to the player on your right.
2. Pass across. Three tiles to the player sitting opposite you.
3. Pass left. Three tiles to the player on your left.

You pass three and receive three each time, so your hand always stays the same size. On the third pass (left), you are allowed a blind pass: you may send on one to three of the tiles being passed to you on this pass without looking at them, and add tiles from your own rack to make three.

The second Charleston: optional

After the first three passes, a second Charleston can happen, but only if everyone agrees to it. It mirrors the first in the other direction: left, across, then right. The blind pass is allowed on the last pass (right) of this round.

Any single player can stop the second Charleston before it starts, with no vote and no reason needed. This is a real decision. If your hand came together nicely in the first round, you may not want to risk passing more away.

A handy way to remember the whole sequence is ROLLOR: Right, Over, Left, then Left, Over, Right.

The courtesy pass

After the Charleston rounds, there is one last optional step: the courtesy pass with the player across from you. The two of you may swap up to three tiles. If you want different numbers, you both pass the lower number: if they want to pass two and you want three, you each pass two. If either of you wants none, there is no swap. Each pair across decides on its own.

The one hard rule: never pass a joker

You can never pass a joker, in any pass, blind or not. Jokers stay with you. Flowers are different: you may pass them, though many hands use flowers, so think twice before you let one go. A blind pass never sends a joker on, because nobody may pass you one. If someone does, give it back.

Common mistakes, and the fix

• Passing tiles you actually need. Read the card first, then pass what fits no hand you are considering.
• Feeding a neighbor. Try not to pass three of the same tile in one direction. You may be handing someone their hand.
• Passing a joker by accident. Check the tiles you pass from your own rack. A joker never goes.
• Forcing the second Charleston. If your hand is set, it is fine to stop it.

The Charleston rewards patience. You are not trying to win it. You are trying to end it with a hand that has somewhere to go.
