Left: the left hand side is enough to communicate the answer; the left pattern can be seen without the counterexamples on the right.
Right: the right hand side is enough to communicate the answer; the right pattern can be seen without counterexamples on the left.
Flipping a BP will switch its sorting.
The following is taken from the comments on page BP513 (keyword left-narrow):
Call a pattern "narrow" if it is likely to be noticed in a collection of examples, without any counterexamples provided.
A collection of triangles will be recognized as such; "triangles" is a narrow pattern. A collection of non-triangular shapes will just be seen as "shapes"; "not triangles" is not narrow.
Narrow patterns tend to be phrased positively ("is [property]"), while non-narrow patterns opposite narrow patterns tend to be phrased negatively ("is not [property]"). |

Left examples have no solution, but they do not break the rules in ways so extreme that it is plainly impossible for them to have a solution, such as including the same image on both sides or including no images per side. (See such as including the same image on both sides or including no images per side. |

See BP522 for the version with links to pages on the OEBP instead of images of Bongard Problems (miniproblems).
See BP968 (flipped) for a version of this Bongard Problem including examples of invalid Bongard Problems that don't even admit a convoluted solution (the same image appears on both sides).
Also see BP1080, which is similar to BP968, but including various different formats of Bongard Problems, distinguishing them from arbitrary images that are not Bongard Problems.
