Double Sur: Court Piece Rang

Double Sur is the classic South Asian trick-taking card game — the one you may know as Double Sar, Double Sir, Court Piece, Rang, Rung, Hokm, Coat or Kot. Four players in two partnerships, thirteen tricks, one trump suit, and a scoring twist that makes every hand tense: winning a single trick means nothing on its own. Tricks pile up face-down in a pending pool, and only when your side wins two in a row — a Double — does the whole pool come home.
HOW IT PLAYS
The trump caller sees their first five cards and declares the trump suit — the rang, or hukum. From there it's Court Piece: follow the led suit if you can, play any card if you can't, and the highest card of the led suit — or the highest trump — takes the trick. Win seven of the thirteen tricks to take the game. Sweep all thirteen as the trump-calling side for a Coat; sweep them against the trump side for the rare Dunk Coat and a big set bonus. Aces carry their own restrictions on completing a Double, exactly as at a real table.
PLAY OFFLINE OR ONLINE
• Offline against the AI — three opponents at Beginner, Intermediate or Expert. Expert counts cards, tracks the trumps still out, keeps its winners in reserve and holds the boss trump for the deciding last trick.
• Online with friends — create a room, share the code, and play a full set with three other people on their own phones.
MADE FOR THE TABLE
• Your whole hand on one screen — all thirteen cards fanned at full size, no scrolling.
• Sound effects and music for card plays, tricks, Doubles, Coat and Dunk Coat, and win or lose — with a mute button.
• Set scoring across games, dealer rotation and the real Double rules — not a simplified version.
• Clean, readable cards designed for phones.
Whether you call it Double Sar, Rang, Rung, Hokm, Troompe or Court Piece, this is the partnership card game played across Pakistan, India and the Gulf — offline or with friends.
