Fit the 6 pieces back into the box. Looks like a reasonable challenge, but it may be not so easy! In fact, this is a quite difficult level 4 puzzle. Its the kind of puzzle that anyone can attack and attempt to solve quickly, usually achieving all but one piece. Kind of keeps you trying but the solution is very elusive. Excellent desk or coffee table type puzzle.
