How to Choose a Hand From the American Mah Jongg Card

Choosing a hand becomes easier when you narrow the search before reading the card line by line. Start with a few features of your rack, find the sections that might use them, and test two or three specific hands. This gives you a manageable set of candidates for the Charleston and the opening turns.

The method below assumes NMJL rules. Have the card being used at your table in front of you; a remembered hand from a different edition may no longer be available.

Use your tiles to choose where to look

A section heading helps you find candidates, but it does not make every tile associated with that heading useful. For example, a collection of even numbers suggests checking 2468. You must still match the printed numbers, suits, and group sizes.

Use the strongest features of your rack to decide which sections deserve your attention first.

Check the sections available on your actual card. These are search prompts, not recommendations to force a hand. Flowers and jokers can support more than one section, so assess them after identifying the rest of the pattern. ^[1]

Test a complete line

Once a hand looks promising, read it all the way across. Identify the exact pair or single requirements, the larger groups, the suit relationships, the X or C designation, and the note beside the pattern.

Mentally assign each tile in your rack to one required position. Count only the tiles that fit under one consistent interpretation of the hand. If the same physical tile could fit two positions, choose one; it cannot fill both.

An extra copy beyond a group's required size does not increase your progress unless another part of that hand can legally use it. If a hand needs a pair of a particular tile and you hold three, the third copy is not automatically another useful tile toward that pair.

Place jokers only after you have assigned the natural tiles. Use them in eligible larger groups, not in single or pair positions. This keeps an attractive joker count from hiding an essential natural tile you still need. ^[3]

Follow a rack through the search

Imagine you begin with this thirteen-tile rack:

Your first search can be Any Like Numbers because six tiles share the number five across three suits. Read the actual lines in that section. Do they use the suits and group sizes you can build? Do the flowers belong? Which group could use the joker?

Your second search might be Consecutive Runs because the 4 dot, 5 dots, and 6 dot create a neighboring-number pattern in one suit. You still need a line that permits those numbers and the required suit arrangement. The 5 bams and 5 craks may contribute to a different part of a candidate or may become surplus.

Do not add the six fives from the first idea to the consecutive-number tiles from the second idea and call the total your progress. Evaluate each complete candidate independently.

The East wind and green dragon are not automatically worthless. Check whether either belongs in the actual lines you found. If neither does, they may be sensible passing choices. Their usefulness comes from the candidate hand, not from a permanent ranking of tile types.

Keep a main option and a related backup

A useful backup shares tiles with the main option. This lets you preserve progress while waiting for information from the Charleston.

For instance, if two verified candidates both use your flowers and a group of the same numbered tile, that shared core can stay in your rack while you compare their remaining requirements. If the backup needs you to abandon nearly every tile in the main hand, keeping both may be impractical.

You do not need to announce your candidate hands. Identify their positions on the card and remember the important difference between them, such as which needs a natural pair and which needs a different suit.

If two candidates remain equally attractive, keep the tiles that serve both while you can. When a required pass or discard forces a choice, compare the particular requirements you would be giving up.

Use the Charleston to refine the shortlist

After receiving a pass, ask what changed. Did you complete a required pair? Did you obtain a tile for a previously unsupported group? Did a new natural tile free a joker for another legal position?

These questions are more useful than asking whether you received a generally desirable tile. A third flower may be valuable for one candidate and surplus for another.

Pass tiles that contribute least to your realistic options, while following the Charleston rules. Do not describe a hand as unsuccessful merely because you chose to pass its tiles. You may be making a sensible tradeoff, but it is still a tradeoff you made.

By the end of the Charleston, aim to identify one leading hand and, where useful, a compatible backup. Knowing what each hand needs will make the next decision easier: choosing which candidate deserves your commitment.
