How to play Slitherlink
Bring your attention to one round of Slitherlink. Draw one closed loop whose edges match the count around every numbered cell. Look at what changes after your first action. Check the rule that explains your first action. Choose a clear next step rather than rushing through the instructions.
Ten 4×4 loop puzzles with all cell clues shown.
A useful comparison
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.
Your goal
Draw one closed loop whose edges match the count around every numbered cell. Use the instructions to see which actions move you towards it. The example below illustrates a decision.
Step by step
- Click an edge to draw, exclude or clear it.
- Count the four edges around each cell.
- Do not branch or form separate loops.
- 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. Use the control method described here for this activity. Use one clear input at a time.
A useful example
A 0 cell has no loop edge around it; a 3 has exactly three. Focus on why the action is allowed, not only its outcome. Keep the controls nearby.
Watch out for this
Several small loops are invalid even if clues match. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
