Any interactions with components are done via the main mouse controls. Direct the mouse cursor to the component you are interested in, hold down the left mouse button and drag to the gem of the same color. However, for the components to be aligned, they must be close to each other. Otherwise, you will not be able to combine objects into one shape.
After the destruction of several gems, components of other colors appear in their place, which opens up the possibilities for you to destroy new shapes of a complex formation. Upon completing a local task, the system adds up the points and takes you to a new level in the game.
