Whether you are playing for the first time or refreshing your knowledge, these simple instructions will help you feel more confident at the table.

What Is American Mahjong?

American Mahjong is a tile-based game played by four players. Each player tries to create a specific combination of tiles that matches a winning hand on the official NMJL card. The game uses skill, memory, planning, and a little luck.

Although American Mahjong shares its history with other forms of Mahjong, it has its own rules and style. One major difference is the use of the NMJL card, which lists the winning hand combinations for the year. American Mahjong also includes special tiles called jokers and a tile-passing stage known as the Charleston.

The goal is simple: collect the correct tiles, follow the rules, and complete a valid hand before the other players do.

Understanding American Mahjong Tiles

Before starting a game, you need to understand the tiles. A standard American Mahjong set contains 152 tiles. These tiles include suits, winds, dragons, flowers, jokers, and other special tiles.

The three main suits are Craks, Bams, and Dots. Craks feature Chinese characters and numbers, Bams show bamboo designs, and Dots display circular patterns. Each suit contains tiles numbered from one to nine. Learning to recognize these suits makes it easier to organize your hand and follow the combinations on the NMJL card.

Wind tiles include East, South, West, and North. Dragon tiles are usually shown in red, green, and white designs. Flower tiles are also part of the game and can appear in different winning combinations.

Jokers are special tiles that can replace certain tiles in eligible groups. However, they cannot be used everywhere. For example, jokers cannot replace a single tile or a pair. Understanding these limits is important because using a joker incorrectly can prevent you from completing a valid hand.

How to Set Up an American Mahjong Game

American Mahjong is designed for four players. Each player sits on one side of the table and receives a rack to organize their tiles. Before the game begins, place all the tiles face down and mix them thoroughly.

Players then build the tile walls according to the set's instructions and the table's agreed setup. The dealer, known as East, begins the deal. Players receive their starting tiles and arrange them on their racks so they can study their options.

Once everyone has their tiles, turn over the current NMJL card. This card is essential because it shows the winning combinations available for the year. Every player should have access to the same card during the game.

How to Read the NMJL Card

The National Mah Jongg League card is one of the most important parts of American Mahjong. It lists the hands players can complete to declare Mahjong. The card changes each year, so players should use the current edition.

The card is divided into sections that group hands by patterns or themes. You may see combinations involving numbers, suits, winds, dragons, flowers, or other tile groups. Each line represents a possible winning hand, and the symbols show which tiles you need.

Take time to study the card before choosing a hand. Look for patterns that match the tiles you already have. Some hands require specific suits or numbers, while others allow more flexibility. The card may also show whether a hand must remain concealed or can include exposed groups.

A concealed hand means you have not exposed any groups by calling discarded tiles. An exposed hand allows certain groups to be shown during play. Always check the card's instructions before deciding which hand to pursue.

What Is the Charleston in American Mahjong?

The Charleston is a special tile-passing stage that takes place before regular gameplay. It gives players a chance to exchange unwanted tiles and improve their starting hands.

During the first Charleston, players pass three tiles to the right, then three across, and then three to the left. Players usually choose tiles that do not fit the hand they hope to build.

A second Charleston may follow, depending on the table's rules and the players' agreement. It generally moves in the opposite direction: left, across, and right. Players may also agree to a courtesy pass when needed.

The Charleston can make a big difference because it helps you collect tiles that match a possible NMJL hand. Try to pass tiles that are unlikely to help you, but avoid giving away tiles that could complete a useful combination for another player.

Basic American Mahjong Rules During Gameplay

After the Charleston ends, regular gameplay begins. Players take turns drawing and discarding tiles to improve their hands. The main goal is to match one complete combination from the NMJL card.

On a typical turn, a player draws a tile from the wall and checks whether it helps complete a winning hand. If the tile is not useful, the player discards one tile face up in the center of the table. The next player then takes their turn.

Players should keep their tiles organized and compare them with the NMJL card throughout the game. A tile that seems unimportant at first may become useful later, so think carefully before discarding.

You can also watch the discards made by other players. These tiles offer clues about the hands they may be building. Paying attention can help you make better decisions and avoid discarding a tile that another player needs.

How to Call a Discarded Tile

In American Mahjong, players may sometimes claim a discarded tile to complete an eligible group. This is called calling a tile. However, not every discard can be called.

A player may generally call a discarded tile to complete a pung, kong, or quint when the combination and current rules allow it. A pung contains three identical tiles, a kong contains four identical tiles, and a quint contains five identical tiles. The completed group is then exposed on the player's rack.

You generally cannot call a discarded tile to complete a single or pair. There are also special rules for calling a tile to declare Mahjong. Since calling rules can affect whether a hand is concealed or exposed, always check the current NMJL card and the rules followed at your table.

How to Use Jokers Correctly

Jokers can help players complete groups and create winning hands more easily. They can usually represent a missing tile in an eligible group of three or more identical tiles, such as a pung, kong, or quint.

However, jokers cannot be used as single tiles or to complete pairs. They also cannot replace every special tile or required symbol. For example, a joker cannot take the place of a flower or a year tile when the card requires that exact tile.

Before using a joker, check the hand you are trying to complete. Make sure the combination allows jokers and that the group meets the rules. Using a joker in the wrong place can make an otherwise promising hand invalid.

How to Win an American Mahjong Game

To win, you must collect all the tiles required for one complete hand shown on the current NMJL card. When your tiles match a valid combination, you can declare Mahjong according to the game's rules.

A winning hand usually contains several groups and a pair, but the exact structure depends on the combination printed on the card. Some hands use repeated numbers, while others include specific suits, winds, dragons, flowers, or other patterns.

Before declaring Mahjong, check every tile carefully. Make sure the hand matches the card exactly, including any requirements for suits, numbers, exposed groups, and jokers. A small mistake can make a hand invalid.

Beginner Tips for Playing American Mahjong

The best way to learn American Mahjong is to start with the basics. Spend time recognizing the tiles and reading the NMJL card before joining a game. You do not need to memorize every possible hand immediately. Instead, focus on understanding how the card works and how tile combinations fit together.

Choose a hand that matches several tiles in your starting rack. Avoid changing your plan too often, but remain flexible when useful tiles appear. During the Charleston, pass tiles that do not support your plan. As the game continues, review your options and adjust when necessary.

It is also helpful to pay attention to exposed tiles and discards. These can give you clues about the combinations other players are collecting. With practice, you will become better at deciding which tiles to keep and which ones to discard.

Most importantly, do not worry about making mistakes while learning. Ask questions, follow the table's rules, and enjoy the process. Playing with experienced players can help you understand difficult situations more quickly.

Common American Mahjong Mistakes to Avoid

New players often make a few common mistakes. One is choosing a hand without checking whether the tiles match the NMJL card. Another is using a joker in a pair or single, which is not allowed.

Some beginners also forget that the NMJL card changes every year. Using an old card can lead to confusion because the available hands may be different. Always make sure you are playing with the correct card.

Another common mistake is discarding tiles too quickly. Before throwing away a tile, consider whether it could help complete another possible hand. It is also important to understand calling rules before exposing a group. Once a group is exposed, your options may become more limited.
