There are names of 5 famous inventors on the left, while there is a grid of arrow symbols on the right. Notice that all the arrows are pointing in a different direction. Press the direction of the arrows so that the first letter of the direction matches with the first letter of the name. So the solution will go like this:
East arrow = Einstein
North east arrow = Neumann Edison
South arrow = Sophokles
North arrow = Newton
West arrow = Watt
As you press the corresponding arrows, a glowing key will appear. Use it to escape this level.
