How many
36: four each of 1 to 9

What they look like

Each dot tile shows that many circles, from one large circle on the 1 dot to nine on the 9 dot. Many American sets also print the number in a corner.

The 1 dot is often a big, decorated circle.

How they are used

Dots are one of the three suits. On the card, the colors of a hand tell you how many suits to use, not which ones, so dots can fill any color.

The matching dragon for dots is the white dragon (soap).

Common mistakes

  • Assuming a blue or green group on the card has to be dots. Colors only say how many suits a hand uses.
  • Pairing dots with the red or green dragon in a hand that calls for matching dragons.
