Round Wind Pung (圈風) in Hong Kong Mahjong: Fan, Double East and Examples
In Hong Kong mahjong, a round wind pung is worth 1 fan: three (or four, as a kong) of the current round's wind — East in the East round, South in the South round — give one fan. The round wind is the same for all four players, whatever seat you're in.
If that wind is also your seat wind — for example the dealer (East seat) punging East in the East round — you score both the round wind and the seat wind fan. Players call it "double East".

The rules for a round wind pung
- Three or four of this round's wind: punged, exposed kong, concealed kong or drawn yourself all count
- A pair scores nothing — as the eyes it's worth no fan
- All four players can score it: in the East round, anyone with an East pung gets it
- Also your seat wind: one fan each for round and seat wind, two in total
- Three or four wind pungs make the limit hands Small Four Winds and Great Four Winds, scored at the limit instead
Which wind is the round wind
A full game has four rounds — East, South, West and North — and in each round every player deals once (repeat deals aside). On this site, "single hand" and "East round" games always use East as the round wind; only a full game reaches the South, West and North rounds.

How it relates to other hands
- Seat wind: a pung of your own seat's wind, also 1 fan. The round wind is shared; the seat wind differs per player.
- Dragon pung: 1 fan for each Red, Green or White pung, no matching needed.
- Small Four Winds, Great Four Winds: three wind pungs plus a wind pair, or four wind pungs — limit hands.
- Mixed One Suit, All Pungs: winds can only be punged, never chowed, so a round-wind hand often turns into All Pungs or Mixed One Suit too.
Round wind odds
A 13-tile opening hand has at least one wind pair (any wind) about 17% of the time; only one of the four winds is the round wind, so the chance of an actual round-wind pair is much smaller.
Over 100,000 hands of computers playing normally on this site, 10% of all wins included a round wind pung, and 10.0% a seat wind pung.
Playing the round wind
- Pung a round-wind pair straight away: it scores for everyone, so it's an instant fan.
- Everyone wants it: discarding the round wind early gives anyone holding a pair a free fan; hold a single round wind until you've seen one in the discards.
- The dealer gains most: in the East round the dealer's East pung is worth two fan, and with No Flowers or a self-draw that's already enough to win.
