• Fences can be converted to almost every planar Graph. Usually regular shapes are used. The most common variants are hexagons, triangles and rectangular with "holes".
• The numbers give the number of neighbouring corners, that bent 90°.
• The diagram is divided into white an gray fields. One of the colors denote correct numbers, the other wrong numbers.
• Cryptoversion: The numbers have been replaced with letters.
• Degrees: Instead of the numbers in the fields, there are numbers given in the grid points, that denote the angle of the path.
