STEP 1 – HOW TO START?

Version 1

When you look closer, you will see the starting information on the left side: there are 4 sliders. One is labeled with the word “Start”. The arrows will lead you to the 5 keys.

Version 2

When you look closer, you will see the starting information on the left side: there are 4 sliders labeled with: “Take”, “out”, “5 Keys” and “to start”

The 5 keys are on the lower surface of the box. They are blocked. It is not possible to rotate or pull them out individually. They must all be rotated by 90 degrees together.
