Cambridge TCG is a peer-to-peer collectors' market, still in active development. You trade directly with other collectors; reference prices are policy-bound guides, not offers or open-data grants. Tell us if anything looks off.

Casual play

For hobbyists who love the game. The playing is the point. No rating shown here. No prize pressure.

Open the lobby →View adventure status →

Lobby — find an opponent, or create a private room and share the code with a friend.
Adventure — level and prior-progress reads remain available; battles and rewards are paused.

Check the lobby before relying on a game write surface.

Fun first. Nothing here earns money or store credit. Ratings live at /play/compete; the boundary is documented at /methodology/play-module.

New? Start with the beginner's guide, then the adventure status page. If you learned OPTCG in Japanese, the bilingual glossary maps every term.
