Blackbox think outside the box is an addictive frustrating game, we are solving them and it gets tough as the level progresses. We will sharing hints for all the levels. Here is the Blackbox think outside the box level 16 walkthrough.
Hint – Two green boxes – This has to do with time. Open it up at least once every hour of the day. Each box represents 12 hours. When you open it during a new hour, it will fill in another piece of the clock. Fill a clock for each light. (Note: You might just need to have the game open for those hours for this to work. It might not be necessary to open that particular level. One of mine lit up on the level select screen, without me opening the level first.)
