You have to make the colors in the main screen, on top, be the same colors as the result box, on bottom-left of the screen. To do it, you have different kind of shapes, each of them could be specific to each level. The only possible action is a left button click if the shape fit on the screen. There are 7 different colors and 3 different borders: If there is a yellow-beige border, the color will go up of 1 color step and will get back to the original position after all colors have been shown. If there is a grey border, the color will stay the same. If there is a brown border, the color will go down of 1 color step and will get back to the original position after all colors have been shown. Each square in a shape is independent. So if you get a shape of 3 different squares, each of the colors of the different squares will go up, stay as it is, or go down of a color step.
