Suit

The three main families of numbered tiles in Mahjong: Bamboo (Bam), Character (Crak), and Dot. Each suit contains tiles numbered 1 through 9, with 4 copies of each number, 108 suit tiles total.

What Are the Three Suits?

In American Mahjong, the three suits form the backbone of most winning hands. They work much like suits in a deck of playing cards, each suit is a distinct family of numbered tiles, and many hands on the NMJL card require you to collect specific combinations from one or more suits.

The three suits are:

• Bamboo (Bam), Tiles depicting bamboo sticks or rods. Numbered 1 through 9.
• Character (Crak), Tiles showing Chinese characters with numerals. Numbered 1 through 9.
• Dot (Circle), Tiles featuring circular dot patterns. Numbered 1 through 9.

Each suit has 9 different numbers (1-9), and each number appears on 4 identical tiles. That gives each suit 36 tiles, and the three suits together account for 108 tiles out of the 166 in a standard American Mahjong set.

The remaining tiles include Winds (16 tiles), Dragons (12 tiles), Flowers (8 tiles), Jokers (8 tiles), and blank/spare tiles.

How Suits Appear on the NMJL Card

The NMJL card is the heart of American Mahjong, and understanding how suits are represented on it is essential for selecting and building your hand.

Color coding. The card uses a consistent color system:

• Blue/Green = Bam (Bamboo)
• Red = Crak (Character)
• Black or Dark Blue = Dot

This color coding matches the traditional colors used on the tiles themselves, making it easier to visually connect the card to the tiles in your hand.

Suit flexibility. Many hands on the card allow you to choose which suit to use. The card indicates this by showing the hand pattern in multiple colors or by using a notation that means "any suit." For example, a hand might show:

• FFF 1111 2222 3333, where the numbers could be in any one suit
• 111 222 333 (one suit) DD (matching Dragons), again, you pick the suit

Other hands are suit-specific, requiring particular combinations across two or three suits. These hands are often more challenging because you need to gather tiles from multiple families simultaneously.

"Like numbers" and "unlike numbers." The card sometimes requires numbers from the same suit (like numbers) or from different suits (unlike numbers). Understanding this distinction matters, "111" in one color means three of the same tile from one suit (Pung), while "1 1 1" in three different colors means one of each suit.

Consecutive vs. matching. Suit tiles can be required in consecutive runs (1-2-3, 3-4-5, etc.) or as matching groups. The NMJL card makes this clear through its layout, but new players should pay close attention to whether a hand asks for sequences or groups of identical tiles.

Suit Strategy Fundamentals

Choosing which suit or suits to focus on is one of the earliest and most important strategic decisions in each hand of American Mahjong.

Single-suit hands require tiles from only one suit. These hands benefit from focus, every suit tile you draw from your chosen suit is potentially useful. However, you are competing with other players who may be collecting the same suit. During the Charleston, pay attention to which suit tiles are coming your way. If you keep receiving Bams, that might signal that other players are not pursuing Bam-based hands.

Multi-suit hands spread your needs across two or three suits. They offer more flexibility since you have more useful tiles to draw, but they also require you to track progress across multiple groupings. These hands can be harder to read from the outside, which helps keep your strategy concealed.

Counting tiles. With 4 copies of each number per suit, building a Kong requires all 4 tiles of one specific number-suit combination. If you see two copies of your needed tile in the discard pile, you know only 2 remain. This counting is simpler within suits than across the entire 166-tile set because the numbers are bounded (1-9) and the copies are fixed (4 each).

Suit balance in the Charleston. When passing tiles during the Charleston, you are often choosing which suit to abandon. Passing away all your Dots, for example, commits you toward Bam and Crak hands. Experienced players make these decisions based on both the tiles they hold and the hands available on the current year's card.

Suit tiles and Jokers. Jokers can substitute for suit tiles in groups of three or more. A hand requiring a Quint of 7 Bam (five 7-Bam tiles) is technically impossible without Jokers since only four 7-Bam tiles exist. Jokers make these oversized groupings achievable and are a critical factor in deciding which hands to pursue.

Recognizing Suit Tiles

New players sometimes struggle to tell the three suits apart at a glance. Here are some quick tips:

Bamboo (Bam) tiles show stick-like shapes arranged in patterns. The 1 Bam is traditionally depicted as a bird (often a peacock or sparrow) rather than a single stick. Numbers 2-9 show clusters of bamboo sticks in the corresponding quantity.

Character (Crak) tiles display Chinese characters (also called "Wan" in Chinese, meaning "ten thousand"). The top portion of the tile shows a Chinese numeral, and the bottom shows the character 萬 (wan). These tiles can be the hardest for Western players to identify at first, but the numerals on top follow a learnable pattern.

Dot tiles are usually the easiest suit to identify. They show circles (dots) arranged in patterns corresponding to the number. For example, 3 Dot shows three circles, 7 Dot shows seven circles, and so on.

Most modern American Mahjong sets include Arabic numerals alongside the traditional designs, making identification much easier for beginners. As you play more, recognizing suit tiles at a glance becomes second nature.
