Method: on the 9×9 lattice, keep every clue cell’s remaining count in pencil. Satisfied clues ban their spare edges exactly like zeros, and chains of forced edges usually travel around two sides of the board before the loop closes. The full step-by-step method is in the how to play slitherlink puzzles guide.
Each number counts the loop edges on that cell. Draw edges between neighboring dots in pencil; the loop must close without crossing or branching.
