Tractor (升级)

How to Play

Four players in two partnerships (you and the player across from you) use two decks (108 cards). Each player gets 25 cards; 8 form the kitty, taken and re-buried by the declaring team. The trump suit plus the current level rank and the jokers are all trump. The declarer leads the first trick; everyone plays one card (or a pair / tractor of consecutive pairs) and must follow the led suit if able. The highest card of the led suit wins unless someone plays trump. Point cards — 5 (5 pts), 10 and K (10 pts each) — are collected by the defending (non-declaring) team. If the defenders collect under 40 points the declarers level up; 40–75 swaps who declares; 80+ lets the defenders level up and take over. First team past Ace wins the match. (This build auto-declares the trump and auto-buries the kitty.)

Controls

When it's your turn, tap cards to select them and press Play. You can play a single, a pair, or a tractor (consecutive pairs), and must follow the led suit when you can — trump cards are highlighted. In single-player you and an AI partner play two AI opponents; in multiplayer, create or join a room and empty seats are filled with AI to make four players.

Tips & Strategy

Trumps are precious — keep them to ruff point-heavy tricks or to win the last trick (the kitty bonus is doubled). Lead low to draw out opponents' high cards, and feed point cards (10s and Ks) to your partner when they're winning a trick. As defenders, fight hard for 80 points to seize the lead.
