Abstract
A three-dimensional puzzle comprising puzzle elements and a reflective surface. In one embodiment, the puzzle elements comprise cubes having visual material thereon. When the cubes are correctly arranged on the reflective surface, the visible cube visual material and the reflection of the cube visual material form a composite image solution. In a second embodiment, the puzzle elements are in the form of relatively flat tiles having visual material on their major surfaces. When the tiles are correctly arranged on a flat surface adjacent the upstanding reflective surface, the visual material on the tiles and the reflection of the visual material combine to form a composite image.
