R8 Tapa-Like Loop: The loops will not be able to intersect at a cell orthogonally adjacent to a neutral clue, since it means that a loop will cross-over to the cell with a neutral clue (which is prohibited in the rules). It can, however, intersect at a diagonally-adjacent cell to a neutral clue, in which case the total of both loops is counted. Therefore, it is possible for a neutral clue to have numbers add up to more than 8.
