Abstract: An improved puzzle of the type in which a target image is applied to the edge of a stack of slats. The slats are shuffled and then reassembled by the user. In the improvement, the strip of target image that is associated with the edge of each slat is extended beyond the edge, along the surface of the slat, allowing the user to more readily perceive the puzzle pattern, particularly on relatively thin slats. The improvement also allows economic manufacture from inexpensive materials by ordinary printing techniques. Slats can be printed flat, then formed by folding.
