Before anyone picks a single tile from the wall, American mahjong has a ritual that no other version of the game has: the Charleston. It's a series of tile passes between players, and it's where you turn a messy opening rack into a hand you can actually build.
It's also the part that confuses new players the most, so here's the whole thing, one pass at a time.
The Charleston is a structured exchange of tiles that happens right after the deal. Every player passes three tiles to another player and receives three in return. It happens in a set order, and it gives everyone a chance to get rid of tiles they don't want and pick up ones they might.
Jokers can never be passed during the Charleston. If you're dealt one, it's yours to keep.
The first Charleston is mandatory. Every player takes part, in this order:
A helpful habit: pick your tiles for the next pass before you look at what's coming in. It keeps the table moving and stops you from second-guessing.
After the first Charleston, the table can do a second one, in the reverse order: left, across, right.
Here's the catch: the second Charleston only happens if everyone agrees. Any single player can stop it. If you already like your hand and don't want to risk breaking it up, you can say so, and the table goes straight to the courtesy pass.
The last step is the optional courtesy pass, which is only between you and the player across from you. Each of you can offer zero, one, two, or three tiles. If you disagree on the number, you both go with the smaller one. So if you want to pass three and your partner only wants to pass one, you each pass one.
On two of the passes, the first left and the last right, you're allowed to "blind pass" (sometimes called "stealing"). Instead of passing tiles from your own rack, you pass along some or all of the tiles you just received without looking at them. It's a great move when you don't want to give up anything from your hand.
We wrote a whole article on this one: Why Would Anyone Do a Blind Pass?
This is where strategy comes in. A few guidelines that help most players:
Your first discard after the Charleston matters just as much. Read The First Discard for why.
The Charleston gets easier the more hands you've seen, because you start recognizing what your tiles can become. That's the fastest skill to build with practice, and it's exactly what Bird Bam practice modes are designed for.
