The puzzle has a chassis (21) with four wheels (22) that allow it to roll along a surface. It supports a three-dimensional puzzle (23) that is locked together by a longitudinal bar. A front piece (25) of the puzzle is locked to the bar by a ball (28) that is pushed by a spring (29) into a hollow in the bar. A back piece (33) is fixed to the back of the bar (34). A part (32), fixed to the front of the bar, recoils into a groove when it is hit and releases the ball, to take the puzzle apart.
