The Story
Where it came from, and why it turned out this way.
Origin and standardizationMid-20th-century Huai’an, Jiangsu · national sport rules in 2022
From Huai’an tables to a national game
Guan Dan arose around Huai’an in Jiangsu, its name inherited from local speech. It combines the moving levels of promotion games, the combination battles of climbing games, and fixed-partner cooperation in two ordinary decks. It spread rapidly beyond Jiangsu and Anhui this century; China’s fifth National Mind Sports Games included it as a demonstration event under the official competitive rules.
Why the second deck matters
With 108 cards, an ordinary rank can appear eight times and each exact face has two physical instances. Rank bombs therefore grow beyond four all the way to ten cards, while the two heart level wilds can stitch scattered cards into a straight, pair run, or larger bomb. Duplication is not an implementation detail—it creates the game’s decision space.
Finishing first is not enough
First place chooses the side that advances, but the partner’s place sets the amount: three levels for second, two for third, one for last. Partnership therefore continues after one hand is empty. When an unanswerable final play survives, the partner can borrow the wind and lead the next round; the ideal result sends both players forward rather than maximizing one individual’s speed.
A common text amid local habits
Rapid spread also produced differences in return-card limits, promotion, run length, and resistance to tribute. After broad consultation, China’s national chess-and-card authority approved the 2022 Competitive Guan Dan Rules (Trial), standardizing combinations, tribute, borrowed leads, promotion, and tournament procedure. This widely used sport text is the default ruleset frozen here.
- A level card has two rankings: elevated just below the jokers in ordinary groups, but back in natural position inside sequences.
- The two heart level cards are wild, yet a wild played alone remains the level single rather than becoming any chosen rank.
- The four-joker bomb uses both black and both red jokers and is the only top bomb that wild cards cannot help construct.
Complete Rules
Start with what a turn allows and how the game is won.
- Players and deck
- 4 fixed partners · two 54-card decks, 108 cards
- Hand
- 27 cards each · counter-clockwise play
- Rank order
- Red joker > black joker > level > A … > 3 > 2
- Opposite seats are permanent partners. Both sides begin at level 2, with the opening leader fairly derived from the fresh session seed. In later deals the first-finishing side becomes the level side, and its current level makes all eight cards of that rank the level cards for the deal.
- The wild rank changes with the deal's current level: when the table is playing level N, only the two ♥N cards from the double deck are wild. The other six cards ranked N are level cards but not wild, and hearts of every other rank are not wild. A lone ♥N remains a level single, and the two ♥N cards alone remain a level pair. Inside a multi-card combination, each ♥N may supply one non-joker card to complete a pair, triple, full house, straight, three-pair run, two-triple run, rank bomb, or straight flush, but it can never replace a joker. The table keeps showing the physical ♥N and adjudicates the declared meaning: at level 2, 3, 4, 4, 5, 5, ♥2 means 33-44-55; at level 3, 4, 5, 5, 6, 6, ♥3 means 44-55-66. Both are three-pair runs.
- A leader may play a single, pair, triple, full house, five-card straight, three consecutive pairs, two consecutive triples, or a bomb. A response must be a higher combination of the same family or a higher bomb, or may pass. When every other player still holding cards passes, the last actual player leads again.
- Straights, pair runs, triple runs, and straight flushes use natural order rather than elevated level order. Ace may be high in 10-J-Q-K-A or low in A-2-3-4-5, AA-22-33, and AAA-222, but may not wrap through K-A-2.
- Bombs rise as four equal cards, five equal cards, straight flush, six through ten equal cards, then all four jokers. Equal-length rank bombs compare rank; straight flushes compare their natural high card; suit never breaks a tie.
- The first empty hand is first place. If the partner immediately finishes second, the opponents are double-down and the deal ends; otherwise play establishes third and last. A partner in second advances three levels, third two, and last one.
- From the second deal, last place gives first place its highest single other than a heart level wild and receives a natural 10-or-lower card in return; double-down makes both losers pay. The owing side resists all tribute if it collectively holds both red jokers.
Your First Game
Use this order of thought to get through a complete game quickly.
- Organize 27 cards by turns remaining. Pair runs, consecutive triples, straights, and full houses shed many at once; breaking one merely to answer now can create several extra tail plays.
- A heart level wild need not be spent immediately. It can complete groups and runs or enlarge a rank bomb, so compare where it removes the greatest number of future turns.
- Your partner’s control is usually more valuable than overtaking once. When the partner has just played and no opponent is close to finishing, passing preserves the partnership’s next lead.
- The table continuously reports hands of ten or fewer. Preserve a high single or pair against an opponent with one or two cards, and lead a shape your partner may accept when the partner is nearly out.
- A non-level 2 is the lowest ordinary rank, while the level jumps above Ace and remains below the jokers. Sequences use the same natural A-to-2 order, with Ace additionally allowed below 2 in the three frozen low windows.
Practical Strategy
Move from knowing the rules to playing with a plan.
- The goal is not merely to finish first but to improve the partner’s place. First plus last advances only one level; arranging a relay or useful lead for the partner can turn the same deal into a two- or three-level gain.
- Borrowing the wind is central: if a player’s final combination survives and that player is out, the partner leads the new round. Plan the last play around the shape the partner most needs to lead.
- Bomb strength is categorical before rank. Any five-card bomb beats every four-card bomb, and a straight flush beats every five-card bomb; a four-card level bomb cannot beat six low equal cards.
- Two decks make counting richer: each exact ordinary face occurs twice and a rank up to eight times. Public plays, your own cards, and reported counts gradually constrain where bombs and runs can remain.
- Tribute changes both cards and the opening lead. Last place leads after single tribute; after double tribute, the player whose higher gift went to first place leads. Return a card that cleans your hand without completing an obvious opponent run.
Winning and Special Rules
Details that are easy to miss but can change the result.
- A wild card's substitute meaning belongs to the play declaration and never changes its printed face. At level 2, the physical cards for the 33-44-55 pair run may therefore appear as 3, 4, 4, 5, 5, ♥2, or 344552 when ranks are written together. Once the level changes to 3, ♥2 immediately stops being wild and only ♥3 may substitute.
- A straight is exactly five cards, a pair run exactly three pairs, and a triple run exactly two triples. Variable-length local runs are not part of this ruleset.
- When the same selected cards have several wild-card meanings, the controls offer separate ‘play as’ actions. The declaration is part of the replayable rule action; neither UI nor AI guesses from selection order.
- If the incumbent has finished and every remaining player passes, the incumbent’s partner borrows the lead. Finished seats are skipped thereafter.
- The initial release offers one coherent official 2022 mode. The newer 2025 world text and scattered regional return/promotion differences are not mixed into it as toggles.
Common Mistakes
The traps new players fall into most often.
- Importing Dou Dizhu’s high 2 into ordinary singles. In Guandan, a non-level 2 is lowest and 3 beats it; only the current level rank jumps above Ace.
- Answering with a six-card straight or four consecutive pairs. Sport-rule runs have fixed lengths; longer is neither stronger nor legal.
- Declaring a lone heart level wild as an arbitrary single. Alone it is the level card; substitution exists only within multi-card combinations.
- Comparing bombs by rank before category. Six low equal cards always beat a straight flush or five-card level bomb.
- Ignoring the rest of the deal after finishing. Unless a double-down ends immediately, whether your partner is second, third, or last changes the promotion.
