Complete setup
Install or load the intended game while connected. Finish any required account or resource steps.
Try the intended mode
Disable connectivity and test the actual play mode, not only the opening screen. Reopen it and check whether progress remains available.
Keep a record
Document the version, device, mode and date. Recheck after updates rather than assuming an old result still applies.
