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 56 walkthrough.
Hint – This is a new one. The left green one. Tap on three different boxes and tap on their hint box once (you don’t need to reveal the hints). You’ll see a different color for each layer in the background of levels 56 – 57. To make sure you get credit for it, tap 56’s hint box last.
