The Charleston Explained: Mastering American Mahjong's Unique Opening

The three passes that only exist in American mahjong — how the Charleston works, when to stop it, and what experienced players watch for.

Why the Charleston Exists

The Charleston is American mahjong's signature ritual — a structured exchange of tiles at the start of every hand that no other variant has. It exists to speed up the game: by trading unwanted tiles three at a time, players approach workable hands within a single round instead of grinding through draws.

The First Charleston (Mandatory)

Everyone passes three tiles: first to the Right, then three Across, then three to the Left. On the second pass, you may elect to stop the "across" pass if every player agrees — advanced tables use this to deny opponents key tiles. Watch what arrives: two of the same tile from different neighbors is information.

The Second Charleston (Optional) and the Courtesy Pass

The second Charleston runs in reverse — Left, Across, Right — and the whole round may be declined by unanimous vote. After it comes the courtesy pass: across-table partners may trade 0, 1, 2 or 3 tiles, and partners signal the count with fingers under the table. This tiny negotiation is where partnerships are won.

What Strong Players Watch

Count your jokers after both Charlestons — they define whether you chase an exposition-heavy hand. Note which neighbor passed you winds and dragons; they are likely collecting suits, which tells you what to safely discard. And remember the etiquette rule that keeps social games friendly: never reorganize your rack loudly during the pass — silent tiles, silent tells.
