DoubleSur

Play Double Sur online with friends or against smart AI. Pick your partner, call trumps, and win the Double — with drop-in multiplayer that keeps the game going.

Winning a trick means nothing. Winning a Double means everything.

Double Sur is a fast, strategic 4-player partnership card game. Team up two-against-two, call your trumps, and outplay your rivals trick by trick to claim the Double and take the set.

PLAY ONLINE WITH FRIENDS • Create a private room, share the code, and choose your partner and seat. • Cross-platform — play together across iPhone and Android. • Drop-in, drop-out resilient: if a player disconnects, AI covers their seat and hands it back on return. If the host leaves, the game continues with a new host. Join a match already in progress and take over an open seat.

PLAY ANYTIME VS AI • Sharpen your game offline against smart, challenging opponents that actually play the odds.

BUILT FOR REAL GAMES • Clean, readable table designed for quick reads and fast turns. • Track your record with player profiles and career stats. • New here? An in-app How to Play guide gets you started in minutes.

Gather your partner, call the trumps, and go for the Double.
