Koop Card Shop Simulator Multiplayer PC

Three diverse modes, each offering a different experience.

Single Player Mode
Play at your own pace. Hire staff to help manage your shop with ease, and your progress is fully saved. You can always join a friend’s multiplayer game using your solo save file.

Co‑op Multiplayer Mode
Invite up to 3 friends and run a great card shop together! Experience the joys of teamwork, unleash your creativity to decorate your shop, share the excitement of opening card packs, and challenge your friends to a friendly card duel on a lazy weekend.

Competitive Multiplayer Mode
Want to compete to see whose shop earns more, whose cards are stronger, or whose card‑battling skills are sharper? Each player runs their own shop on the same street, fighting to attract customers.

Collect Rare Cards

With over 400 cards spanning 7 generations and a wide variety of card frames to enrich your collection, there’s always more to discover. Some mysterious cards only appear under special conditions. Legend tells of a set worth a fortune—with a bit of luck, you might obtain it on your very first day, while others may never catch even a glimpse of the myth.

Wager your cards and enter the duel!

Classic Duel

Featuring an auto-battle system based on elemental strengths and weaknesses, this mode delivers a fast-paced and accessible card battling experience—full of thrilling randomness and luck.

Advanced Duel

A turn-based battle mode where you command every move—decide which cards to play, choose attack targets, and master the timing of each spell. Total tactical control is in your hands.

Uncover the Secrets of the Street

Venture Beyond Your Shop
Step into the streets and discover all kinds of surprises—maybe a hidden card, a game of basketball, a rooftop view, or a trader who buys spare cards. Challenge the local gym, too. Whenever you explore, something unexpected is always waiting.

Showcase Your Creativity: Customize Your Shop

Use a wide range of interactive decorations, plants, shelves, card display walls, flooring, ceilings, plush toys, and statues to design a shop that’s uniquely your own.
