Mahjong Dots, Bams, and Craks
Dots, bams, and craks are the three numbered suits used in American mahjong. Each suit contains four copies of every number from one through nine. The card often uses these suits in relationships rather than naming one fixed suit, so players must understand both the physical tiles and the abstract suit roles shown by color.
Dots
Dots use circles or coin-like symbols. Count the circles to identify the number. One dot may be especially ornate.
Bams
Bams use bamboo-like sticks. One bam is the exception and usually shows a bird.
Craks
Craks combine a Chinese number character with a red character beneath it. Focus on the upper character to identify the number.
Card colors do not name fixed suits
Colors printed on the annual card show suit relationships. A three-color line normally needs three different suits. The player chooses which physical suit fills each color role unless the line names a suit or matching dragon.
Common visual traps
One bam versus a flower
One bam shows a bird but remains a numbered suit tile.
Dense dot patterns
Six, eight, and nine dots can look similar at a glance. Count the circles.
Crak characters
The red lower character repeats across the suit. Learn the upper number characters through comparison.
Practice routine
- Sort each suit from one through nine.
- Reveal mixed tiles one at a time.
- Name the number and suit aloud.
- Practice one bam until it is never mistaken for a flower.
- Find one-, two-, and three-suit examples on the card.
Numbered-suit questions
Can a joker represent any numbered tile?
Only inside an eligible group of three or more identical tiles.
Is one suit stronger than another?
No. Their value depends entirely on the chosen hand and tile availability.
Do card colors match tile ink colors?
No. Card colors show relationships between suits.
