Shengji: Tractor Card Game

Shengji (升级 / 拖拉机), also known as Tractor, is the beloved Chinese card game - now a single-player tractor card game you can play offline, anytime, for free.

Shengji is a trick-taking game where two teams race to climb the ranks from 2 all the way to Ace. This is the full three-deck game (162 cards) against 3 AI opponents in the classic 2-vs-2 partnership format, just like at the family table. Prefer a quicker round? A lighter two-deck mode is one tap away - but three decks is the real thing.

Recent changes:
Fixed who wins when a thrown lead gets beaten:

• When two players trump the same throw, only the biggest combination in the lead decides it — the tractor, else the pair, else the highest single. The rest is no longer compared.
• A trump play with the higher pair no longer loses to one whose leftover single happened to be bigger
• The small joker now takes a throw of all singles, instead of losing to two middling trumps
