The Bgraamiens Lines Puzzle is a worthy challenge for puzzle-makers with some time to sink into it. The 1,000 pieces feature black lines on a white background. The lines come from all directions and are different thicknesses, with no clear pattern. Made of strong cardboard and recycled paper, the puzzle is 24 inches by 24 inches when fully assembled.
The monochromatic design adds to the challenge, as solvers will need to identify white spaces and borders at every turn. For those who might want a hint or two, the backs of each piece are marked with letters indicating an area of the puzzle to be completed. Bgraamiens is a leading maker of some of the world’s most complex puzzles and Lines is no exception.
