Now you should put the upper slider on the back of the box in the appropriate position, next to the picture of the star. When you have decoded all 4 words, you will get the following words:
“Star”, “Ring”, “Lampe” and “Magnet”

As soon as the 4 sliders are placed according to these symbols, the central lock can be removed.

Now you have opened the box and reached the secret compartment.
