Why it goes right, across, left
The first round sends 3 tiles to each other player once. The second round comes back the other way. Across the six passes, each player can move up to 18 tiles they don't want and take 18 in. That is how a weak deal becomes a playable hand before the first discard.
The blind pass, worked
On pass 3 (left), you have only two tiles you're willing to give up. Pass those two and one tile from the three just handed to you from across, without looking at it. That is a blind pass, also called stealing. It is only allowed on the last pass of each round.
With two or three players
The League's short-handed rules skip the Charleston. See two players and three players, including the ghost-player house rule for tables that keep it.

What is a blind pass in mahjong?
On the last pass of each round, passing on tiles you just received without looking at them, when you don't have three tiles you want to give up.
How does the courtesy pass work?
After the Charleston, each player may trade 0 to 3 tiles with the player across. If you ask for 3 and they offer 1, you both pass 1.
