Abstract: A puzzle box includes a floor, side walls, a first end wall, and a second end wall to define a container, with a lid positioned to overlie the container, wherein the first end wall receives a through-extending shaft, wherein the side walls and second end wall include fixed block members. The shaft is directed through openings in flanges fixedly and orthogonally mounted to a bottom surface of the lid, wherein the shaft is only projected into the container through the first end wall and the remaining end walls and side walls are arranged to confuse availability of the shaft. A modification of the invention includes the floor formed with spring-biased rods selectively projected into the container, wherein the lid, when mounted on the container, includes locking blocks, wherein the locking blocks are positioned in locking engagement with the shaft and are in biased communication with the shaft.
