A practical guide to Slitherlink

Use a short break to learn the rhythm of Slitherlink. Draw one closed loop whose edges match the count around every numbered cell. Choose a clear next step rather than rushing through the instructions. Read the objective before making your first input. Check the relevant rule before repeating a move.

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

Build familiarity through play

Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Use the example to check your reasoning.

What you need to achieve

Draw one closed loop whose edges match the count around every numbered cell. An attractive position is not enough unless the goal is met. Start with a deliberate move.

A walkthrough of the rules

  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.

Input guidance

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Check any mode label before starting.

One way to understand the rules

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. Notice the change in the playing area.

Avoid this misunderstanding

Several small loops are invalid even if clues match. Read the feedback to see why an action did not have the expected result. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
