A Jigsaw Cube is constructed from boxes stacked into a cube with the width, height and depth set according to the number of Levels (5 in this example). The individual boxes on each of the 6 cube faces are initially positioned randomly, so that the images on the cube sides appear scrambled. The object is to rearrange the boxes as needed to properly reconstruct the images on each of the 6 faces of the cube.
A box can be moved by clicking it with the mouse and then dragging it to another position within the cube. The selected box will be outlined in yellow, and a green outlined box will follow the mouse movement until released at a new position. When a group of adjacent boxes are in their relative correct positions, they can be moved as a group (as shown in this example).
Solving a Jigsaw Cube is usually fairly easy, depending on the number of Levels. The real challenge comes with trying to maximize your score by minimizing the number of moves used to reconstruct the images. Moving a group of 'solved' boxes counts as a single move, so building fragments of the image and then moving them together can often increase your score. As boxes are moved, they essentially exchange places -- the boxes that are displaced by moved boxes are sent to the positions vacated by the moved boxes. Because of this, with a little cleverness and planning, you can sometimes solve 2 portions of the puzzle with a single move. Naturally, with higher Levels, the difficulty increases, as well as the potential for an impressive score. As with a normal jigsaw puzzle, it might be easiest to start by positioning the corner and edge pieces of the image. The Border Around Images option can be set in the Options screen to help identify corner and edge boxes. An Opened Box will reveal the position (row and column) where that box belongs.
