Slitherlink is another Japanese puzzle like Sudoku. It has only three simple basic rules, but can be devilishly devious. But the question is will Slitherlink finally be successful? According to the statistics of my website the number of page views for my Slitherlink pages increase enormous (last week +300%). So will this be the breakthrough of Slitherlink? I hope so because Slitherlink is still one of my favorite puzzles.
For the people who are not familiar with Slitherlink a small wrap up. The three rules for Slitherlink are:
1. Connect dots with vertical / horizontal line and make one loop,
2. Numbers are the hints to know how many lines can be drawn around it. There may be any number of lines around cells without number,
3. Lines cannot be crossed or branch off.
