How to play Slitherlink

Slitherlink on 850305 is organised around a clear objective: Draw one closed loop whose edges match the count around every numbered cell. Begin with build a repeatable approach and use the playbook beside the game.

Ten checked 4×4 loop puzzles with all cell clues shown.

Build a repeatable approach

Try a consistent sequence of observing, choosing and checking the result. Keep the sequence even when the position or challenge changes.

Your goal

Draw one closed loop whose edges match the count around every numbered cell.

Step by step

1. Click an edge to draw, exclude or clear it.
2. Count the four edges around each cell.
3. Do not branch or form separate loops.
4. Check puzzle verifies every clue and loop connectivity.

Controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution.

A useful example

A 0 cell has no loop edge around it; a 3 has exactly three.

Watch out for this

Several small loops are invalid even if clues match.
