What are Singles and Pairs hands in American Mahjong?

Singles and Pairs hands are NMJL hands made up only of single tiles and pairs (two of a kind). No pungs, kongs, or Quints. The whole 14-tile hand is just individual tiles and pairs of tiles. They are also entirely concealed, you cannot expose by claiming discards.

Why can't you use Jokers in pairs?

NMJL rules state that Jokers cannot be used in pairs. A pair must be two natural matching tiles. Jokers may still be used in singles, but most Singles and Pairs hands rely heavily on natural tiles in the pair slots, which is what makes the category challenging.

Are Singles and Pairs hands always concealed?

Yes. Every hand in the Singles and Pairs section is concealed. You cannot call discards from other players to expose tiles. Every tile must come from your own draws and from the Charleston passes.

Are Singles and Pairs hands good for beginners?

They are usually not the easiest place to start. Concealed-only play with no claiming is a difficult mode, and the Joker restriction in pairs makes the category demanding. Year hands and Consecutive Run hands are gentler entry points for new players.

Singles and Pairs hands in American Mahjong

The Singles and Pairs section on the NMJL card contains some of the most demanding hands on the card. They're made up entirely of single tiles and pairs: no pungs (three of a kind), no kongs (four of a kind), no Quints. The whole hand is just individual tiles and tiles in pairs.

These hands are also entirely concealed. You can't expose your tiles by claiming discards from other players. Everything has to come from your own draws and from the Charleston (the tile-passing rounds at the start of the game).

What "Singles and Pairs" means

Each Singles and Pairs hand has 14 tiles arranged in some combination of single tiles (alone) and pairs (two of a kind). No three-of-a-kind groups. No four-of-a-kind groups. No Quints. Just singles and pairs.

The card sets the exact pattern. Some hands have several pairs and a few singles. Some lean heavier on singles. Some require pairs to come from specific suits or specific number ranges.

A note about Jokers

Here's the critical rule for this category: Jokers cannot be used in pairs. A pair has to be two natural tiles. (There's no rule against using Jokers in singles, but most Singles and Pairs hands rely heavily on natural tiles in their pair slots.) This restriction means Jokers are far less useful here than in any other section of the card.

If you've drawn a Joker-heavy hand, Quints or Winds and Dragons are usually a better fit than Singles and Pairs.

Why the category exists

Singles and Pairs gives experienced players a category that asks for something different. Most hands reward Joker management; Singles and Pairs rewards patience and tile tracking. Most hands let you call discards; Singles and Pairs makes you play your draws as they come.

The category appeals to players who prefer a more traditional style of play. Pungs and kongs are accessible to everyone. Singles and Pairs asks you to read the wall, time your draws, and protect a concealed hand from exposure. When it comes together, the points are high. When it doesn't, you may end up with a dead hand. That's the trade-off.

How they play in practice

You're playing without backup. No claiming discards, no Joker shortcuts in pairs. Every tile in your hand has to come from your own draws or from the Charleston passes.

The Charleston is your main supply. With no calling allowed, the Charleston is the largest source of tiles you'll get outside the wall. Pay close attention to what's coming through.

Tracking the wall matters more here. If a tile you need has already been discarded twice, the third copy is the only one left, and the fourth would have to come through the Charleston.

These hands often go dead. A Singles and Pairs hand that doesn't come together by the end of the wall is a dead hand. That's the cost of the category, balanced against the higher point value when one does land.

Defense is harder against Singles and Pairs players. With nothing exposed, opponents can't tell what you're chasing. Some players choose Singles and Pairs precisely for the deception.

Where to find them on the card

Every NMJL card has a Singles and Pairs section, usually toward the bottom. The hands change every year and are NMJL's protected content. You'll need an official card to see this year's patterns. Order one from the National Mah Jongg League for $14, and our card-reading guide walks through how the notation works.

When this category is a good fit

Consider Singles and Pairs when:

Your starting tiles include many distinct types in modest quantities (lots of variety, no big clusters).
You're comfortable playing concealed hands and tracking discards carefully.
You enjoy a high-risk, high-reward style of play.

You might pick another category when:

You drew several Jokers. They're less useful in this section than anywhere else on the card.
You're newer to the game. Year hands or Consecutive Runs are gentler starting points.
