Abstract: A three-dimensional take-apart and put-together puzzle is provided. The device comprises a plurality of discs with each disc having spaced first and second planar side surfaces. A male element projects from each first planar side surface. A female element extends through the disc defining a receptacle for receiving the male element of a different disc. A radial slot is formed in each disc with each radial slot alignable with the radial slot of a corresponding disc upon positioning the first planar surfaces of a pair of discs against one another forming an overlapping, unconnected disc set whereby the aligned radial slots of a disc set mateably connect with the aligned radial slots of a corresponding disc set creating interlocking disc groups. Each interlocking disc group releasably connects with at least one other interlocking disc group through mating of the male elements with the female elements.
