Guandan (掼蛋) is a four-player partnership game born in Jiangsu and now played everywhere from family tables to national tournaments. You and the player across the table share a ladder that climbs from 2 to Ace: two full decks, four jokers, 27 cards each, and every deal is a race to shed your hand first.
Bombs beat any ordinary play and outrank one another, the two heart level cards are wild, and losers pay tribute: their best card, handed to the winners before the next deal. The first team to clear a deal at its own Ace level takes the match.
