Rever's puzzo and stuff

 Internal Conflicts On puzz.link, regions are made of individual edges, each separating two different cells. However, using those individual edges, it is possible to create internal borders that do not form regions. These three puzzles are using this "exploit", which result in some interesting consequence stemming from error-checking. Due to the subtleties of internal border, the rules have been modified to encompensate that. Changed sections are in bold. Country Road Rules and link Draw a non-intersecting loop through the centers of some cells which passes through exactly two bold borders in, or on the exterior of each region . A number in a region represents how many cells in the region are visited by the loop. Orthogonally adjacent cells across a bold border may not both be unused. You can solve this puzzle here using puzz.link's interface Heyawake Rules and link Shade some cells so that no two shaded cells are orthogonally adjacent and the remaining unshaded cells for...
