All Terminals and Honors in Chinese Official Mahjong (MCR): Points, Examples and Odds

In Chinese Official Mahjong, All Terminals and Honors (混幺九) is worth 32 points: every tile in your winning hand is a 1, a 9 or an honor — no 2 to 8 at all. Terminals can't form chows, so the hand is always four pungs and a pair, or seven pairs.

The rules

• All 14 tiles are 1s, 9s or honors
• Normal form: four pungs (or kongs) and a pair; no chows possible, but you may pung and kong
• Seven Pairs form: seven pairs of terminals and honors also count (plus Seven Pairs)
• You need both terminals and honors: terminals only is All Terminals (64 points), honors only is All Honors (64 points), and neither adds All Terminals and Honors
• Thirteen Orphans also uses only terminals and honors, but it's a separate 88-point special hand and doesn't add this fan

What it does not combine with

Under the non-repeat principle these are not counted:

• All Pungs (6 points): the normal form is always four pungs
• Pung of Terminals or Honors (1 point): every set is one, and none are counted
• Outside Hand (4 points): every set contains a terminal or honor, so not counted

These still count: Dragon Pung, Prevalent Wind, Seat Wind (depending on which honor pungs you have), Two / Three / Four Concealed Pungs, Double / Triple Pung, All Types, Half Flush, One Voided Suit, Seven Pairs.

Scoring examples

Every hand below is scored live by this site's scoring engine — the same code as the game — including the fan left out by the non-repeat rules.

How it relates to other fan

• All Pungs: the normal form always is All Pungs, so it isn't added.
• Seven Pairs: the seven-pairs version starts at 56 points.
• All Types: terminals spread over three suits plus winds and dragons often give all five types.

Odds

The hand needs all 14 tiles from just 13 kinds (52 tiles) of terminals and honors. About 6.6% of 13-tile opening hands hold 8 or more of them, only 1.8% hold 9 or more.

How to build it

• Many terminals and honors, with pairs: the hand is all pungs, so pairs are what you need to pung.
• Pung freely: the normal form is already All Pungs; claiming costs nothing.
• Lots of pairs? Try seven pairs: with five or six pairs and a concealed hand, the seven-pairs version works too.
• Fallback: if it stalls, honor pungs and terminal pungs still make All Pungs with honor fan, or Half Flush.

FAQ

How many points is All Terminals and Honors?

32 points in Chinese Official Mahjong, not combined with All Pungs, Pung of Terminals or Honors or Outside Hand.

Can I pung for it?

Yes. It doesn't need to be concealed; the normal form is four pungs anyway, so pungs and kongs are fine.

What's the difference from Outside Hand?

Outside Hand only needs a terminal or honor in every set and the pair, with 2–8 tiles allowed inside chows; All Terminals and Honors uses nothing but terminals and honors, and scores far more.

Can Seven Pairs be All Terminals and Honors?

Yes. If all seven pairs are terminals or honors, you score both, 56 points or more.
