One Layout Slitherlinks Jun 13, 2008

Then at Nikoli we thought that if we specify the layout, what differences in the flavor will the authors bring to the puzzles? And yes, we really tried it. We asked many authors to make a Slitherlink puzzle based on the same layout, and here we have 19 (nineteen!) of these puzzles.
