Make sense of the Charleston in American mahjong

What is the Charleston for?

The Charleston happens after the deal and before ordinary play. It lets all four players exchange unwanted tiles while beginning to choose possible hands from their card. You are improving a starting position, not committing to a final hand immediately.

Before the first pass, sort your rack by suit and number. Notice pairs, flowers, and groups that might fit a card hand. Pick a few possible directions rather than holding every tile for every possibility.

The passing order, one step at a time

1. 1Right
2. 2Across
3. 3Left

For the first round, choose three tiles, place them face down for the player on your right, and receive three from your left. Review your rack, then choose three to pass across. Review again before passing three to your left.

The first round is compulsory in standard four-player play. The next round happens only if every player agrees to continue. If someone stops it after the first round, no one needs to explain why. If a second round begins, complete all three passes: left, across, right.

Keep the rounds separate in your head: right-across-left first; left-across-right second. Wait until the current exchange is complete before preparing the next one.

How to choose three tiles to pass

Ask which tiles help your strongest current possibilities. A pair can be useful evidence, but it is not a promise that a particular hand will work. Look at the whole rack and the requirements of the card before breaking up or protecting a group.

For example, if your leading options use bams and dots, an isolated crak might be a candidate to pass. That does not make it automatically correct: a different card hand might use it. Reassess each time new tiles arrive.

Avoid handing someone a ready-made matching group when you have equally useful alternatives. Still, improving your own rack matters more than trying to guess everyone else’s entire plan. There is no universally correct three-tile pass without seeing the hand and card.

What does a blind pass mean?

On the final pass of either round, you may pass along one, two, or three of the incoming tiles without looking at them. This is called a blind pass, sometimes “stealing.” Use tiles from your rack for any remainder so the outgoing pass still totals three.

The opportunities are the first round’s final left pass and the second round’s final right pass. A blind pass is not an extra exchange and does not let you inspect tiles before sending them onward. If you are learning at a physical table, ask for help with the passing sequence before touching the incoming tiles.

Finish with the courtesy exchange

Opposite players may agree to exchange up to three more tiles. If one wants to pass three and the other wants to pass one, they exchange one. Either can choose zero. This is different from the three-tile passes of the Charleston rounds.

After the exchanges, check your tile count: the dealer has 14 and the other players have 13. The dealer makes the first discard. Now the regular draw-and-discard game begins.

Three mistakes you can avoid

In Mahjong Pals, follow the direction prompt and select the requested number of tiles. Practicing a pass at a time helps connect the rule to the movement you see at the table.

• Do not pass jokers, even when you do not want them for your current plan.
• Do not mix up “across” with the next player around the table. Across means your opposite player.
• Do not rush into the optional round before everyone has agreed.
