Born in Huai’an

Guandan (掼蛋) took shape in the 1960s in Nanzha commune, Huai’an county, Jiangsu — hence its other name, “Huai’an Run Fast”. In 2024 the Jiangsu Guandan Association named Sun Zhaocheng its inventor.

Two stories behind the name

One says guanlan and guandan sound alike in the Huai’an dialect, and the name simply drifted. The other reads it literally: guan means to slam down, dan means bomb — a game fought with bombs.

Run Fast plus Eighty Points

The rules blend two local games, Run Fast (跑得快) and Eighty Points (八十分, also called Upgrade 升级): the race to empty your hand from the first, the win-and-promote structure from the second. After a Huai’an Guandan website launched in 2005 it reached Suqian, Nanjing and Yangzhou; today over 20 million people play in Jiangsu and Anhui alone.

Now a competitive sport

In January 2017 China’s General Administration of Sport issued unified competition rules; a trial competitive ruleset followed in late 2022. In 2023 Guandan appeared as a demonstration event at the 5th National Mind Sports Games.

Your partner is half the game

Even when you finish first, how far you climb depends on your partner: three ranks if they come second, two if third, only one if last. Holding a strong card to open a path for them is half the skill.

Promotion and the A gate

You start at rank 2 and climb with each win until you reach A. A must be won outright — and if your partner finishes last, the A does not count as cleared.

Beat what is on the table

You must match the leader’s combo type and card count with a higher hand. If you cannot — or would rather save your cards — you pass. When the other three all pass, the last player to play leads again.

The combos

Single · Pair · Triple · Full house (triple + pair) · Straight (exactly 5 in a row, 10-J-Q-K-A high, A-2-3-4-5 low) · Pair run (exactly three consecutive pairs, AAKKQQ high, AA2233 low) · Triple run (exactly two consecutive triples, 777888). None of these can be extended.

Bombs break the rules

A bomb beats any normal combo regardless of type. More cards is stronger; on equal size the higher rank wins. Four jokers — the royal bomb — beats everything.

Rank card and the wild

The rank card is the strongest single below the jokers. Only its two HEARTS are wild — they substitute for anything but a joker, which is how bombs can reach ten cards.

End of a round

The round ends once two players empty their hands; your team’s two finishing places decide the payout and the promotion.

Rules vary by region

Local variants are common. In Huai’an the card returned in the tribute (进贡) phase can be anything; the Nanjing style requires a low card, 10 or below. The “three failed A rounds” rule — dropping the team back to rank 2 — is used in some places and ignored in others. This app follows the 2017 national ruleset.

Hand types & ranking

Royal bomb (四王) All four jokers

All four jokers — two big, two small. Nothing beats it. The wild card cannot stand in for a joker, and with two decks there are exactly four, so it appears at most once per round.

8-card bomb (八炸) Eight of a kind

Eight of a kind. With wilds a bomb can reach nine or ten cards, and bigger is always stronger — but all of them still lose to the royal bomb.

7-card bomb (七炸) Seven of a kind

Seven of a kind. Only an eight-card bomb tops it.

6-card bomb (六炸) Six of a kind

Six of a kind. From this size up, bombs outrank the straight flush.

Straight flush (同花顺) Five in a row, one suit

Five in a row in one suit. A special bomb: above a five-card bomb, below a six-card bomb. 10-J-Q-K-A high, A-2-3-4-5 low.

5-card bomb (五炸) Five of a kind

Five of a kind. Loses to a straight flush, beats a four-card bomb.

4-card bomb (四炸) Four of a kind

Four of a kind. The smallest bomb, yet it still beats every normal combo.

Triple run (钢板) Two consecutive triples

Two consecutive triples (777888). Exactly six cards, never longer; compared by the lower group.

Pair run (木板) Three consecutive pairs

Three consecutive pairs (778899). Exactly six cards, AAKKQQ high and AA2233 low.

Straight (顺子) Five in a row

Five in a row, suits irrelevant, never longer than five. 10-J-Q-K-A high, A-2-3-4-5 low.

Full house (三带二) Triple plus a pair

Triple plus pair, five cards. Only the triple counts when comparing, so the attached pair can be anything.

Triple (三张) Three of a kind

Three of a kind, matched only against other triples. Three jokers do not make one.

Pair (对子) Two of a kind

Two of a kind. Two big jokers is the strongest pair and two small jokers the next; one of each is not a pair.

Single (单张) One card

One card. Order runs big joker > small joker > rank card > A > K … down to 2.

Two separate worlds

Combos split into normal hands and bombs. Normal hands only compete against the same type and the same card count; a bomb ignores type and beats any normal hand. You may not be able to top a straight with a straight — but one bomb ends the argument.

Bomb order

More cards always wins: a 5-card bomb beats a 4-card bomb, a 6-card beats a 5-card. At equal size the higher rank wins, so 8888 beats 5555.

Where the straight flush sits

A straight flush (five in a row in one suit, e.g. ♠5♠6♠7♠8♠9) is a special bomb: stronger than a 5-card bomb, weaker than a 6-card bomb. Same shape as a straight, but matching suits put it in a different league.

Jokers as a pair

Two big jokers are the strongest pair, two small jokers the next. Big and small are different ranks, so one of each is not a pair, and three jokers cannot make a triple. The only joker bomb is all four together.

The royal bomb

Four jokers (two big, two small) — nothing beats it. With only two decks there are exactly four jokers, so it appears at most once per round. Two exceptions worth knowing: the wild card cannot stand in for a joker, so it can never build a royal bomb; and even a nine- or ten-card bomb made with wilds still loses to it.

Rank card and the wild

The rank card is the strongest single below the jokers. Only its two hearts are wild (逢人配) — they stand in for anything except a joker.

Comparing within a type

Pairs, triples, full houses and straights only compete at equal card count. A full house is judged by its triple, a straight by its highest card, and the runs by their lowest group.

Regional rule styles

Guandan is played a little differently from place to place. These are the three styles the app supports — the 2017 national standard plus two regional variants.

National 2017 ruleset
What differs
Return card10 or lower only
Promotion1+2 → 3 ranks / 1+3 → 2 / 1+4 → 1
Three failed ANot used
EndTime and round limits

The competition standard issued by the General Administration of Sport. This app defaults to it and most online ranked play follows it.

Bomb order follows the national rules. With wilds a bomb can reach nine or ten cards, all still below the royal bomb.

Huai’an original
What differs
Return cardNo limit — any card
Promotion1+2 → 3 ranks / 1+3 → 2 / 1+4 → 1
Three failed ACommon — back to rank 2
EndUntil A is cleared

The folk style of the birthplace. With no limit on the returned card you can hand back a big one to rescue your partner.

Bomb order is the same, though some tables refuse to recognise nine- and ten-card bombs.

Nanjing strict
What differs
Return cardStrictly 10 or lower
PromotionNo gain on 1+4 · demoted one rank if partner is last
Three failed AUsed
EndUntil A is cleared

The style settled around Nanjing, with the harshest promotion. Finishing first alone is not enough, so partner play matters most.

Bomb order is identical, but the tight promotion makes players hoard bombs to the end.
