American Mahjong Dragon Color Rules

American mahjong card notation often links dragons with suits by color: red dragon with craks, green dragon with bams, and white dragon with dots. This relationship helps interpret lines that use matching or contrasting card colors.

Standard suit-and-dragon relationships

Craks and red dragon

Characters are associated with the red dragon.

Bams and green dragon

Bamboos are associated with the green dragon.

Dots and white dragon

Circles are associated with the white dragon, commonly called soap.

Read a dragon line accurately

  • Identify which printed colors represent suits in the line.
  • Match the dragon to the intended suit relationship.
  • Check whether the line requires the same suit, opposite suit, or any suit.
  • Do not assume the physical ink color on every tile set matches the card's notation.
  • Verify pair and group sizes before using a joker.

Card color is structural, not decorative

Different colors on the card tell you how suits must relate. They do not necessarily name a fixed suit until the player chooses the suit assignment permitted by the line.

Dragon color questions

Is the white dragon always dots?

In the standard American suit relationship, white dragon corresponds with dots.

Does a red printed group always mean craks?

Not automatically. Card colors often show relationships among suits. Read the card's notation instructions rather than assigning a suit from color alone.

Are red, green, and white dragons interchangeable?

No. They are three distinct tiles unless the exact line allows a flexible dragon choice.
