基本信息
- 人数:4 人,对家一队(你和对面的人一队)。
- 牌:两副牌共 108 张。每人 25 张,剩下 8 张是底牌。
- 出牌顺序:逆时针,你出完轮到右手边的人。
- 级别:两队各有自己的级,都从 2 开始;这局打几,几就是级牌。
亮主、定主牌
- 发牌时,谁拿到级牌就可以亮出来,定这局的主花色;一对级牌可以反主,一对王可以打无主。
- 第一局谁亮主谁坐庄;没人亮主就翻底牌定主。
- 主牌 = 大王、小王、所有级牌、所有主花色的牌。任何主牌都比任何副牌大。
- 主牌从大到小:大王 > 小王 > 主花色的级牌 > 其他级牌 > 主花色 A、K…… dapai.app 默认2 为常主(2 排在级牌下面,房主可以关掉)。
扣底
庄家拿起 8 张底牌,再扣回 8 张。最好别扣分牌:如果闲家赢了最后一墩,底牌里的分会翻倍算给闲家。
出牌和跟牌
- 牌型:单张、对子(两张一模一样)、拖拉机(相连的对子,级牌不占位)、甩牌(一次领出同一门里几手最大的牌)。
- 跟牌:领出的是哪一门,有这门就必须出这门;领出对子,这门有对子必须跟对子;领出拖拉机,有拖拉机必须跟拖拉机。
- 没有这门时,可以出主牌毙掉,也可以垫别的牌。
- 一墩里最大的牌赢,赢的人领出下一墩。
- 甩牌失败时只能出其中最小的那部分;是否再罚 10 分由房主设置(默认不罚)。
计分和升级
- 分牌:5 是 5 分,10 和 K 是 10 分,一共 200 分。只有闲家赢下的墩算分。
- 抠底:闲家赢了最后一墩,底牌分翻倍给闲家(单张 ×2、对子 ×4、两对的拖拉机 ×8)。
- 闲家 80 分或以上:上台当庄家,120 分起每多 40 分再升 1 级。
- 庄家守住:闲家 40–75 分升 1 级,5–35 分升 2 级,0 分升 3 级。
- 打到 A,并在 A 守住的一队赢得整场。
常见问题

- 四个人,两副牌(108 张),坐对面的两个人是一队。每人 25 张,剩下 8 张是底牌。

Shengji (Tractor) rules in English
Shengji (升级, "level up"), also called Tractor (拖拉机) or 80 Points (八十分), is a Chinese trick-taking
card game for four players in two partnerships, played with two decks. Both teams start at level 2 and climb one hand at a time;
the first team to win at level A wins the match.
Setup
- 4 players; partners sit opposite each other.
- Two decks, 108 cards: 25 each, with 8 left as the bottom (kitty).
- Play goes counter-clockwise. The current level's rank is the level card.
Trumps
- While dealing, a player holding a level card can show it to set the trump suit; a pair of level cards overrides; a pair of jokers means no trump suit.
- In the first hand the declarer becomes dealer; if nobody declares, the bottom cards decide the trump suit.
- Trumps are both jokers, every level card and the whole trump suit. Any trump beats any side card. Order: big joker > small joker > level card of the trump suit > other level cards > trump-suit A, K, … By default dapai.app also treats every 2 as a trump (the host can turn this off).
Playing tricks
- Combinations: singles, pairs (two identical cards), tractors (consecutive pairs; the level rank is skipped) and throws (several top cards of one suit at once).
- You must follow the suit led; follow a pair with a pair and a tractor with a tractor if you can. If you are out of that suit, you may ruff with a trump or discard.
- The dealer picks up the 8 bottom cards and buries 8.
Scoring
- 5s are worth 5, 10s and Ks are worth 10 — 200 points in total. Only the attacking team (not the dealers) scores points from tricks.
- If the attackers win the last trick, the bottom's points are multiplied (×2 single, ×4 pair, ×8 two-pair tractor).
- Attackers with 80+ take over as dealers (one extra level for every 40 from 120). Otherwise the dealers go up 1 level (40–75), 2 levels (5–35) or 3 levels (0).
