Mahjong characters · 筒子 tǒng zi

What do the circles on mahjong tiles mean?

The dots are strings of coins, drawn as rings. There is no character anywhere on them — you count the circles and say the number yourself, which is exactly the kind of practice that builds recall.

Every face in this suit

On the tile	Called	Reading	What it is
—	一筒	yī tǒng	1 of dots
—	二筒	èr tǒng	2 of dots
—	三筒	sān tǒng	3 of dots
—	四筒	sì tǒng	4 of dots
—	五筒	wǔ tǒng	5 of dots
—	六筒	liù tǒng	6 of dots
—	七筒	qī tǒng	7 of dots
—	八筒	bā tǒng	8 of dots
—	九筒	jiǔ tǒng	9 of dots

There is no writing on these tiles at all, and that is genuinely useful if you are learning: a face with a character on it lets you read the answer off, while a face with pips makes you produce 六 liù from nothing. Recall is what builds memory; recognition mostly feels like it does.
