One source of truth

PandaDesign is the authority for Panda design assets and instructions. These rules apply to new work and updates to existing apps.

Boards and pieces

Use the approved local piece sets: Neo (default), Pixel, Disc or RhosGFX.
Copy assets into each app. No Wikipedia, Wikimedia, GitHub or CDN piece requests while playing.
Coordinates belong outside the squares, or are turned off. Never inside, including on phones and printed diagrams.
Keep a1 dark and h1 light. Keep the board square and the pieces upright when flipped.

Skins

Each app can have its own considered design. Support light and dark modes, use real artwork, and keep the board easy to read. Historical screenshots are references, not permission to override the current rules.

Brand

Use the full-body panda beside the app title. Use the head only for a browser or home-screen icon. Put the full panda on a light tile on dark backgrounds.

Using the library

Download a piece set from Boards & pieces, or have your coding tool copy it from PandaDesign into the app. Design changes are made here first, then copied out deliberately. Existing apps keep their own files and work offline.

The source repository also contains the complete instructions, generator, migration tools, and historical collections. Internal files are not served by this website.
