It has been appearing in my local paper under the name Loop (which doesn't google well).
It is a variant of Slitherlink where you draw a single non-intersecting line around a grid.
Numbers indicate how many of the diagonally adjacent cells contain a line with a 90 degree turn.ers
Cells without a turn are either blank or have a straight line through them (you have to work out which).
Newspaper puzzles have also included a starting turn in the top-left but they are not needed and easily deduced.
Example puzzle:
- Code: Select all
