Everyone has their favorite puzzle swap board - once you get it, you can really rack up the culture unaided. But everyone has their own bugbear too, a puzzle swap board that you can't seem to get right. Maybe because of a lot of similar-looking lines, or indistinguishable blades of grass or patches of sky.

For whatever reason, I am interested in knowing everyone's top favorites and the ones you love to hate.

Please answer the poll over here. If you don't know which great art puzzle has which name, never fear! Visual aids are provided in the link.
