Getting started with Slitherlink

Practice beyond the first move

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. Make the next step deliberately.

What you need to achieve

Draw one closed loop whose edges match the count around every numbered cell. The feedback beside the game helps you follow the round. Keep the controls in easy reach.

How a round unfolds

  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.

Getting comfortable with the 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. Avoid pressing the same control repeatedly while a move is being processed.

A closer look at one example

A 0 cell has no loop edge around it; a 3 has exactly three. Apply the same reasoning to the position in your own round. Verify the rule before continuing.

A common point of confusion

Several small loops are invalid even if clues match. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
