Every lock needs its own key unless you are going to pick it. And in the ColorDock game, the keys and locks must have the same color in order for it to open. To do this, you must bring both elements closer to each other and several multi-colored keys will appear at the top of the field and gradually go down, where many multi-colored locks located in several rows are concentrated. To complete a level, you need to arrange the locks on the upper level so that each one matches the color of the descending key. To achieve the result, use the gray mouse, moving it between the locks and changing their places in the ColorDock.
