Keep going offline
Your mission progress is saved on this device. Some cloud and coding tools need the internet, but your work is not lost.
If the connection drops
Continue reading your mission brief and coding instructions. Use Retry sync after the connection returns.
Protect your progress
Project PNG files wait safely in browser storage for upload. Session backup JSON files can be restored from the mission check-in page.
MakeCode offline
Ask the school to install the official MakeCode Arcade offline app before the programme. Lumos Mission Lab does not claim to replace it.
Offline mission brief
Nova City’s school traffic lights have failed. Your first program must cycle safely through red, green, and yellow. Your second program must detect a crossing request, stop traffic, wait for a safe timed crossing, then restore the traffic state.
When the connection returns, open any mission page and choose Retry sync. Queued project files and progress will upload automatically.
