Riichi mahjong, up to your first win

From what a yaku is, through when to declare riichi, dora and furiten, and on to draws and defence — learned by tapping real tiles.

What to know about this ruleset

Why yaku and riichi matter

You learn why a yaku is required and when declaring riichi is worth it, in real situations.

Furiten and defence

The mistakes beginners make most — furiten and picking safe tiles — get their own lessons.

A feel for scoring

Worked examples show how fu and han turn into a final score.

Frequently asked questions

I do not know a single yaku.

The course introduces the most common ones first, so no prior knowledge is needed.

What is furiten?

A rule that stops you winning on a discard when you have already discarded a waiting tile. The course shows it in play.

Can I play straight afterwards?

Yes — you continue into an AI match or an online table with friends.
