Saves belong to the browser and domain where you played. Moving to this hub or your custom domain requires a transfer on the same device.
On desktop, open the original game. Open your browser’s developer console, paste this export code, and run it. It downloads only game progress and preferences, with no login or multiplayer tokens.
On mobile, use a desktop browser with the original saves or keep the old game available. Browser-local data on a different device cannot be retrieved here.
Import replaces matching game settings and progress on this domain. Export a backup here first if you have existing progress.
