Press the Solve button to get the solution algorithm and the visual 3D representation of the steps. The program will try to guess and fill the colors as you move forward, this is why it sets the first and last yellow, and all red fields automatically not allowing you to set an invalid scramble. Start by adding the three blue stickers, then go on with the green, yellow and finally the red. The vertex and center pieces are already set because these can be solved very easily and the edge pieces are left blank because solving these is the real challenge here. Press the Edit button to set the color of the puzzle manually.
