How to play Slitherlink
Read the aim of Slitherlink, then make your first move. Draw one closed loop whose edges match the count around every numbered cell. Keep the game area visible while you use its controls. Use the opening round to become familiar with the layout. Check the relevant rule before repeating a move.
Ten 4×4 loop puzzles with all cell clues shown.
Focus on one rule
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Keep the objective visible.
Your goal
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.
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. A new-round button replaces the current round.
A useful example
A 0 cell has no loop edge around it; a 3 has exactly three. Use the example as a guide rather than a substitute for reading your board. Keep the controls nearby.
Watch out for this
Several small loops are invalid even if clues match. A different version of the game may use a different rule. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
