The Charleston in American Mahjong: Step-by-Step Rules

The Charleston is American Mah Jongg’s distinctive pregame passing ritual. It gives players a chance to improve their starting tiles before normal drawing and discarding begins. For beginners, the challenge is not strategy at first—it is remembering the direction, timing, and limits of each pass.

Quick answer

In a standard four-player American Mahjong Charleston, everyone passes three tiles at the same time: right, across, then left. A second sequence commonly reverses direction: left, across, then right. Players may then make a courtesy pass with the person opposite them. Jokers can never be passed, and procedural details should be confirmed before play.

Rules basis and important variation

This guide describes common National Mah Jongg League-style American Mah Jongg for four players using the 2026 card. The annual card defines legal hands, but current published guidance and the rules governing your table control Charleston details.

Social groups, teachers, and tournaments may differ on stopping the second Charleston, blind-pass technique, what happens after an exposed pass, and penalties for mistakes. Use the sequence below as a learning framework, then confirm the exact procedure for your game. Three-player play requires a separate passing method.

Why the Charleston exists

After the deal, most racks contain tiles from many unrelated hands. The Charleston lets you remove low-value tiles and receive new possibilities without spending turns drawing and discarding.

It also creates information. A tile you pass may return later, suggesting that it is unwanted around the table. A suit that never appears may be scarce. However, the passes are not open discards; keep all passed tiles face down and do not announce them.

The Charleston ends before East’s opening discard. It is part of setup, not ordinary turn play.

Before the first pass

Confirm that:

  • East has 14 tiles and every other player has 13.
  • All players use the same year’s card.
  • No exposed tiles are on any rack.
  • Everyone knows which physical direction is right, left, and across.
  • The table has agreed on second-Charleston and blind-pass procedure.
  • Every player understands that Jokers cannot be passed.

Players may sort their tiles and compare them with the card. You do not need to commit to one hand, but choose two or three candidate lines before selecting your first three tiles.

First Charleston: right, across, left

A useful memory phrase is right, across, left.

Step 1: Pass three tiles to the right

Choose three unwanted tiles from your rack. Place them face down together. When everyone is ready, slide the group to the player on your right and receive three from the player on your left.

Do not look at incoming tiles before your outgoing group is committed. Simultaneous exchange prevents a player from changing a pass based on what arrives.

Step 2: Pass three tiles across

Study the three received tiles along with your rack. Select three tiles and pass them face down to the player directly opposite you. Receive three from that player.

Across passes can feel less intuitive on a crowded table. Make eye contact with your opposite player and keep the two groups separate until both are committed.

Step 3: Pass three tiles to the left

Select three tiles and pass them to the player on your left. You receive three from the right.

Under many standard procedures, this is one of the passes where a limited blind pass may be allowed. A blind pass means forwarding one or more incoming tiles without first looking at them because you do not want to release three tiles from your rack. It is not permission to pass Jokers, change the number passed, or conceal an error. Follow the current rules used at your table; some teachers omit blind passing entirely for a first lesson.

The first right-across-left sequence is generally treated as the required Charleston round in standard four-player play.

Second Charleston: left, across, right

The reverse sequence is left, across, right.

Step 4: Pass three tiles to the left

After the table applies its required continuation or stopping procedure, select three tiles and pass left. Receive three from the right.

Do not assume your social group’s vote or veto method is universal. Some tables ask whether anyone wishes to stop at a specified point; organized rules may define exactly when and how that choice is made. Agree before tiles move.

Step 5: Pass three tiles across

Exchange three face-down tiles with the player opposite you. As before, both players should commit their outgoing tiles before examining incoming ones.

Step 6: Pass three tiles to the right

Pass three tiles right and receive three from the left. This final right pass is another point where common procedures may allow a limited blind pass. Use only the method permitted by your governing rules.

At the end of the second Charleston, every player should still have the same tile count they had immediately before each exchange. The Charleston changes tile composition, not hand size.

The courtesy pass

After the main Charleston, opposite players may make a courtesy pass. This is negotiated separately by each pair across the table.

A common procedure is:

  1. Ask the player opposite how many tiles they want to exchange.
  2. Agree on a number, usually from zero through three.
  3. Both players pass that exact number face down at the same time.
  4. No Joker may be included.

If one player wants one tile and the other wants three, the pair passes the lower mutually accepted number rather than forcing the larger exchange. A courtesy pass is optional and cooperative.

Do not reveal what you are passing or request a specific suit. The courtesy pass is not trading by identity; it is a simultaneous blind exchange.

What tiles should a beginner pass?

Pass tiles that are least useful across your realistic card options. A good first-pass decision often follows this order:

  1. Eliminate tiles that fit none of your shortlisted hands.
  2. Keep pairs, because they are harder to complete and cannot be replaced by Jokers.
  3. Keep flexible tiles that work in more than one candidate line.
  4. Keep natural tiles that could support Joker-free singles or pairs.
  5. Reassess after every incoming group rather than repeating the same plan.

Avoid passing solely by suit because your hand may need multiple suits. Read the color relationships and notes on the card first.

A practical example

Imagine you hold several tiles that support two related Consecutive Run possibilities, a pair needed by both, and three isolated Winds that fit neither. The Winds are reasonable first-pass candidates.

After the right pass, you receive two useful numbered tiles and a Flower. Now one candidate becomes much stronger. For the across pass, protect the shared pair and the new useful tiles. Release tiles tied only to the weaker option.

This is the central Charleston skill: update your plan after every exchange.

Blind passing explained carefully

A blind pass is sometimes called a “steal.” The player uses allowed incoming tile or tiles as part of the outgoing pass without looking at them first. It exists to protect useful rack tiles late in a Charleston sequence.

Blind passing does not mean:

  • Looking at an incoming tile and then pretending it was blind
  • Passing fewer than the required total
  • Passing a Joker
  • Taking back a committed tile
  • Using the technique on any pass you choose

Because the eligible pass, number of tiles, and handling method can differ by authority or event, beginners should ask, “Are we allowing a blind pass, and exactly how?” before the Charleston starts.

Jokers during the Charleston

The rule is straightforward: never pass a Joker. This includes every Charleston pass and the courtesy pass.

If you receive a Joker, stop the procedure without exposing private information and ask the table to apply the correction rule. A social learning game may simply return and replace it; a tournament may impose a defined penalty or dead-hand ruling. Do not invent a correction in organized play.

A Joker may remain in your rack and later support an eligible grouping, but it cannot solve your need to select passable tiles. If you have many useful tiles and a Joker, use a permitted blind-pass procedure if available rather than slipping the Joker into the pass.

Charleston etiquette that prevents disputes

  • Keep every outgoing group face down.
  • Commit the full group before touching incoming tiles.
  • Pass and receive at the same time.
  • Do not announce tile names or show disappointment.
  • Keep separate groups separate, especially across the table.
  • Do not take back a tile once the pass is committed.
  • Count three tile backs before looking.
  • Pause immediately if a group contains the wrong number.
  • Ask about local procedure before, not during, an edge case.

A smooth rhythm is helpful, but accuracy is more important than speed.

Common Charleston mistakes

Passing a Joker

A Joker cannot be passed. Check the face of every outgoing tile before turning the group face down.

Passing in the wrong direction

Use a spoken cue from the leader: “First right,” “now across,” and so on. Do not move until all players are ready.

Looking before committing

Choose and release outgoing tiles before inspecting incoming ones. Otherwise, you gain information unavailable to other players.

Locking into one hand too early

The Charleston can transform your rack. Keep at least one backup possibility until the later passes.

Assuming the second-round procedure

Stopping rules are an area of variation. Confirm the current published or tournament procedure rather than relying on a memory from another group.

American Mahjong Charleston FAQ

Is the Charleston required?

The first Charleston is generally required in standard four-player NMJL-style play. The handling of the reverse sequence and any stopping point should follow current published guidance or the event’s rules.

How many tiles do you pass?

Each standard Charleston exchange moves three tiles per player. A courtesy pass may involve an agreed number from zero through three.

Can you pass a Joker in the courtesy pass?

No. Jokers cannot be passed during any Charleston exchange or courtesy pass.

Can you pass back a tile you just received?

Yes, unless a specific rule limits the action. Once you receive and inspect tiles, they become part of your rack and can be selected for a later pass.

Can the Charleston create Mah Jongg?

A player may emerge from passing with tiles matching a card hand, but table procedure determines when a win may be declared. Do not interrupt an unfinished Charleston; follow the governing rule for completing passes and declaration timing.

Does three-player American Mahjong use the same Charleston?

No. Three-player methods modify or omit parts of the four-player passing pattern. Choose a specific published variant before play.
