All Pungs (Dui Dui Wu) in Hong Kong Mahjong: Fan, Examples and Odds

In Hong Kong mahjong, All Pungs (對對糊, dui dui wu) is worth 3 fan: when you win, all four sets are pungs (three identical tiles, or a kong), plus one pair. A single chow — claimed or built in your hand — breaks it.

Cantonese tables need 3 fan to win, and All Pungs reaches exactly 3 fan on its own, which makes it one of the most common ways to get over the minimum.

The rules for All Pungs

• All four sets are pungs or kongs: claimed, self-drawn, exposed or concealed kongs all count
• No chows at all, so you cannot chow
• The pair can be any tile
• Any suits: characters, dots, bamboo and honours can be mixed

How All Pungs waits

A ready All Pungs hand has only two shapes.

Two pairs: waiting on either one

You hold two pairs; drawing or claiming either tile turns it into a pung and wins. Two tiles to wait on, so it wins more often than a single wait.

Single wait: four pungs done, waiting for the pair

All four pungs are complete and one lone tile waits for its match. Only one tile wins.

How All Pungs is scored

Fan add up, but within one family only the highest counts. The fan below are computed live by the same scoring code the game uses; with no flowers you also get No Flowers for 1 fan.

How it relates to other hands

• Four Concealed Pungs: all four pungs drawn yourself (concealed kongs count) is the limit hand 坑坑糊, scored at the limit instead of All Pungs. A pung completed by someone else's discard is not concealed.
• Pure One Suit: four pungs all in one suit score both — 10 fan · Limit.
• Mixed One Suit: one suit plus honours, stacks with All Pungs. Honours can only be punged, never chowed, so Mixed One Suit often ends up as All Pungs too.
• Mixed Terminals: pungs of only terminals and honours add another 1 fan.
• All Honours, Great Four Winds: all honour tiles, or four wind pungs, are always All Pungs; both are limit hands.

All Pungs odds

How many pairs in the opening hand

Is it worth forcing All Pungs?

We let computers play on this site's table: in every hand, the player with the most opening pairs had to go for All Pungs — pung only, never chow, and never win with anything else — while the other three played normally. Then we compared how often it came off, and the average result, with the same opening hands played normally.

Source: computer play on this site. In each of 16,000 hands the seat with the best start forced All pungs (對對糊); the other three played normally (Normal level). Results in base units (3-fan minimum, 10-fan limit, half-spicy scoring, discarder pays).

The result surprises most players: under Cantonese scoring, with enough pairs, forcing All Pungs pays better than playing normally.

• With 3 or more pairs, forcing it works 33% of the time, for an average result of +12.4 base units; with the same starts played normally, the player made All Pungs only 3.7% of the time and averaged +1.3.
• With 4 or more pairs, almost half come off (47%), averaging +19.9 against +3.5 playing normally.
• Finished hands averaged 4.6 fan after 13.9 draws: All Pungs already clears the minimum, and dragon pungs or Mixed One Suit pile on fan quickly.
• The exception is starting with one pair or none: forcing it then does worse than playing normally (see the first row).
• When the computers play normally, All Pungs is 5.8% of all wins.

Which hands suit All Pungs

• Four or more pairs in the opening hand, or several pungs already: you are only a few tiles away.
• Pairs that score: dragon, round-wind and seat-wind pairs add fan when punged, so they help twice.
• Pairs whose tiles haven't been discarded: once two of a tile are out, that pair can no longer be punged; only the last copy from the wall can help.
• Others notice after two pungs: two or three exposed pungs and no chows tell everyone you're going for All Pungs, and they'll hold the tiles you need.

When to give up: less than half the wall is left and you still need two or more sets, or the tiles your pairs need are already in the discards. Switch back to normal play or start defending. To practise the call, open a table of online Hong Kong mahjong — the computers play with you and count the fan for you.
