A puzzle of the type wherein a movable object, e.g. a ball, is manipulated into a recess or round maze by tilting a substantially horizontal playing surface has reflectors which transmitt an image of the playing surface, in a different plane from that of the object, to a viewing area. One mirror at 45‹ to the object may be used to give an errect image (Figs. 9 and 10) or two mirrors with their planes at 45‹ to each other may be used to give an errect and laterally inverted image, as shown in Figs. 1 and 3. Two puzzles 44, 60 joined side by side may be arranged to pivot so as to bring either of them above the object area. Alternatively different puzzles may be removably located by a leaf spring and peg arrangement above the object area. The puzzle may be confined within plastic walls, the upper wall being translucent and the lower being transparent.</p> |
