Head Scratching Eye Catching 3D ConundruMS

This follow-up to Eye-Pleasing, Mind-Teasing 3-D Conundrums offers more visually dazzling puzzle fun, all with contemporary-looking graphic and computer-generated images that increase the solving pleasure. Each conundrum takes up a full, colorful page. A group of delicate golden keys seem to explode like fireworks on the deep purple page. The puzzle: find the one key that's different than the others. Another figure has nine components, held together by screws. Which three different color screws have to be unscrewed to let the shape fall into three parts? Can pieces of a chessboard be joined so that none of the queens can capture any of the others? Every problem is as pleasing to the eye as it is challenging to the brain.
