ConCin opens from the extension toolbar in a dedicated tab. The startup screen offers Solo, Quick Play, Settings, and How to Play.
Use Solo to choose the table and game length before dealing. Quick Play starts an immediate deal with one computer player. Online rooms are not included in the first public release.
The current game and preferences are saved locally. ConCin does not require an account. Settings provides language, card-back, and card-face choices, and the interface supports reduced-motion preferences.
If the game page does not open, confirm that ConCin is enabled and use its toolbar action again. Clearing extension data or uninstalling ConCin removes saved local progress.
