Slitherlink rules

Following the footsteps of Sudoku, Kakuro and other Number Logic puzzles, Slitherlink is another family of easy to learn addictive logic puzzles which were invented in Japan. Using pure logic and requiring no math to solve, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

Slitherlink is a loop-forming puzzle. Unlike other logic puzzles, Slitherlink are solved by drawing lines around the clues according to the rules until a closed loop is formed.

Slitherlink puzzles come in many sizes and range from very easy to extremely difficult taking anything from five minutes to several hours to solve. However, make one mistake and you’ll find yourself stuck later on as you get closer to the solution...

Classic Slitherlink

Each puzzle consists of a rectangular lattice of dots with some clues in various places. The object is to link adjacent dots so:

• The value of each clue equals the number of links surrounding it.
• Empty squares may be surrounded by any number of links.
• When completed, the solution forms a single continuous loop with no crossings or branches.
