The invention relates to a ball-shaped puzzle comprising a spherical support element (1; 31) and a plurality of movable puzzle elements (16; 33) which all have substantially the same size and shape, the movable puzzle elements (16; 33) being slidably engaged in a trajectory (2; 32) on the outside of the spherical support element (1; 31), the trajectory (2; 32) defining a plurality of predetermined positions on the outside of the spherical support element (1; 31) between which the puzzle elements (16; 33) are movable. The spherical support element (1; 31) comprises a core and a plurality of trajectory forming elements (15; 45-46) which form the trajectory (2; 32), the trajectory forming elements (15; 45-46) being fixed onto the core (13; 43-44) by a snap-fitting arrangement (40-41).
