One line, one hand

Each line on the card is one hand of exactly 14 tiles. Each chunk separated by a space is one group:

2468222 4444 666 8888Any 1 suitX · 25

Read this line as: a pung of 2s (3 tiles), a kong of 4s (4 tiles), a pung of 6s and a kong of 8s, all four groups in the same color → all in one suit. The X · 25 on the right means you may expose groups and the hand is worth 25 points.

This site’s card, “House Card 2026”, has 50 hands in 10 categories. In the game, press “Show the full card” in the card panel to see them all.

Colors mean “same suit or different suits”

The colors on the card do not stand for bams, craks or dots. They tell you which groups must share a suit:

  • Same color = same suit (you choose which one)
  • Different colors = must be different suits

In this hand (ignore the opening pair of flowers for now), 4444 and 8888 share a color and 6666 has a different one. You can make “4444 and 8888 in craks with 6666 in dots”, or “4444 and 8888 in bams with 6666 in craks” — but the 6666 can never be in the same suit as the other two groups.

Letters and symbols

On the cardMeaning
1–9The number on a suit tile
FFlower
N E W SNorth, East, West, South
DDragon, which must match the group’s suit (Green with bams, Red with craks, Soap with dots)
0Soap used as a zero, belonging to no suit
XExposed: you may call other players’ discards to complete groups
CConcealed: no exposures; you may only call the tile that wins

The number on the right is the hand’s value. The harder a hand is to build, the more it’s worth.

“Any like numbers” and “any consecutive numbers”

Some hands don’t fix the numbers. The card prints them using 1 as an example and notes “any like numbers” or “any consecutive numbers” next to them:

Like NumbersFFFF 1111 111 1113 suits · any like numbersX · 25
Consecutive RunFFF 111 2222 33333 suits · any consecutive numbersX · 25

The first hand is “4 flowers plus one group of the same number in each of the three suits”: you could use all 5s, or all 8s. The second is three consecutive numbers: 1-2-3, 4-5-6 and 7-8-9 all work.

Year hands

Every card has a category of hands built from the current year. 2026 is four single tiles: 2, Soap (as 0), 2, 6.

2026FF 2026 2222 6666Any 2 suitsX · 30
2026NEWS 2026 2026 DD3 suitsC · 35

2026 is made of singles, so jokers can’t be used — only real tiles. The second hand is concealed (C), and its NEWS means one each of North, East, West and South.

Singles and pairs

This category is made up entirely of pairs and singles, so not a single joker can be used. That means these hands are always concealed, and they score the highest:

This site’s card is an original design, not the official card the National Mah Jongg League (NMJL) publishes every year. It reads the same way, though: learn this one and you’ll be able to read the official card too.
