Step 1
The 4 sliders (with arrows)
Look at the spacebar from all sides. Pay special attention to the page with 9 numbers circled. To the left of the "number house”, you will find 2 numbers above the triangle and 2 numbers below the circle. Look at the two numbers separately and think about what relation they have to the “house of numbers”. You must understand that circles 12 and 69 could be important. The same goes for the numbers under the circle - that is, 46 and 79. If you look at the side of the frame that shows a circle with two rings around it, you will see that this side has something to do with the previous one. "House number" must be made. Now you need to check which arrangement of the circles points to which symbol. Then you have to set this symbol to circle and triangle using the slider. When you've set two sliders, note that you can also see two shapes on the opposite side of the gap. You will find 2 more numbers above the rectangle and the hexagon. This also takes you to 2 symbols that you can set with the slider.
