Colourshift

For the logic game fans many games have been made. One from them is this boy. You have to connect coloured pipes, the name is Colourshift. Many different types of pipes appear on the screen, some are with light some not. Connecting the grey with coloured one will turn the grey into the colour. Your task is to connect all that no grey stays. It sound easy but the rotating is key. More pipes with different colours arrive and the number of light sources increases as well.
