Invention relates to a three-dimensional spherical sliding puzzle having a frame made of eight corner pieces, and seventeen square pieces each mobile in grooves bordering the corner pieces and along guide grooves defined in the corner pieces. The square pieces are moved independently, one at a time by one finger of a user while other the other square pieces are locked in place. The corner pieces are easily extrudable and can be assembled by the snap-connections-and are detached seamlessly with each other by symmetrical male-female-couplers. The grooves provided by the corner pieces of the ball frame have 18 points, where each of the 17 square pieces can be situated, whereby one free point is utilized for moving the pieces one at a time. The corner pieces each include retaining nails having a tip thickening located at an end thereof for releasably clamping to control buttons of the square pieces.
