American mahjong, from reading the card to mahjong

How to read a hand card, what to pass in the Charleston, and when a joker can and cannot be used — learned by tapping real tiles rather than reading about them.

What to know about this ruleset

Reading the card first

Categories like year, evens and quints, and how card notation maps to real tiles.

Charleston practice

You decide what to pass and what to keep across all three passes, on real hands.

Joker rules in play

Where jokers are allowed, where they are not, and how to swap one out of an exposed group.

Frequently asked questions

Do I need to know another mahjong first?

No. The course starts from what a tile is, so no prior knowledge is assumed.

Can jokers go anywhere?

No — only in groups of three or more identical tiles, never in pairs or singles. The course shows this in play.

Is it free?

The entire course is free.
