In 3-D Logic, your goal is to create a path between squares of the same color on the cube. Rotate the cube by moving your mouse pointer around it. Just click a color and then drag your mouse along the grey squares to create the colored path (black squares are "out of bounds"). More colors and path options are added as the level increases. If you're having any trouble with clicking and dragging to create a colored path, you can also click a color and then single-click along the grey route to create the path.
Controls: Mouse to create path and rotate the cube.
