Nikoli Slitherlink & Sudoku

Slitherink are engaging logic puzzles with some simple rules and four numbers: 0, 1, 2, and 3. They're Nikoli's original creations, known as Sli-Lin in Japan, and they provide endless enjoyment. The grid features scattered dots and numbers; connect the dots with a vertical or horizontal line until you've created a single loop with no crossings or branches. The trick is that when you reach a number, its value determines how many lines, or "walls" surround it. For extra solving pleasure, the collection also includes 45 sudoku.
