The Charleston, Explained: A Beginner's Walkthrough of the Tile Pass
The Charleston is the part of American mahjong that does not exist in any other version of the game — a structured exchange of tiles before play begins. It is also the part that intimidates new players most, mostly because nobody explains the shape of it. The shape is simple. Here it is once, end to end.
What the Charleston is
After the deal, every player is holding 13 random tiles and a card full of target hands. The Charleston is three (sometimes four) rounds of passing that let everyone trade away tiles they do not want. Statistically it roughly doubles the useful tiles in your hand — it is the engine of the whole game, and skipping it is not an option at an American table.
The shape: right, across, left
- First pass — to the right. Choose three tiles, place them face down, and slide them to the player on your right. Everyone passes at the same time; you pick up the three coming to you from the left.
- Second pass — across. Choose three more (they can include tiles you just received) and pass them to the player opposite you.
- Third pass — to the left. Same again, to the player on your left. This is the pass where the blind pass is allowed (below).
- Optional courtesy. If all four players agree, the Charleston runs back the other way — left, across, right. At the very end, the two players across from each other may swap one to three tiles by mutual agreement. This last bit is the courtesy pass.
Most home games run just the first three passes plus the courtesy swap. Watch it once in the practice game and the rhythm makes immediate sense — the AI passes with you in real time.
What to pass (and what never to pass)
The pass is not about dumping your worst tiles; it is about declaring a direction. Look at your thirteen, glance at the card, and ask which one or two sections your hand already leans toward. Then:
- Pass: single tiles that fit nothing — an off-suit number with no neighbor, a wind you have one of, a flower when you are not building a flower hand.
- Keep: pairs, anything with a same-suit neighbor (a 5 next to a 7), all jokers, and whatever the card section you are leaning toward asks for.
- Never pass a joker. It is against the rules, full stop — a joker in the pass is returned and the offender is usually teased for the rest of the evening.
One nuance for pass three: the blind pass. If you have only two tiles you are willing to give up, you may take up to three tiles from the incoming stack without looking at them and forward them on — as long as the total you pass is three. You cannot blind-pass on the first two rounds.
After the pass: commit (loosely)
When the Charleston ends, your hand is roughly twice as coherent as it was at the deal. Now pick your lane: choose one, at most two, card sections to chase, and start discarding everything that serves neither. Our Charleston strategy guide goes deeper into reading which way a hand wants to go; the printable rule card keeps the pass order in front of you until it is muscle memory.
Quick Answers
What is the Charleston in American mahjong?
A structured tile exchange after the deal: each player passes three unwanted tiles to the right, then across, then left, with an optional reverse run and a courtesy swap at the end. It is unique to American mahjong and mandatory at most tables.
Can you pass a joker in the Charleston?
Never. Passing a joker is against the rules. If one slips through by accident, it is returned to the player who passed it.
What is a blind pass?
On the third pass only, you may forward up to three tiles from the incoming stack without looking at them, as long as you pass three tiles total. It is not allowed on the first two passes.
Is the courtesy pass required?
No. After the third pass, the two players seated across from each other may agree to swap one to three tiles — but either player may decline, and the whole second Charleston (left, across, right) only happens if all four players want it.
