Find your footing in Slitherlink

One thing to notice as you play

After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.

What the game asks you to do

Draw one closed loop whose edges match the count around every numbered cell. Keep that objective in view throughout the round. Notice how the game responds to your input.

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.

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. Read a button’s label before selecting it. 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. Apply the same reasoning to the position in your own round. Choose a deliberate next step.

Avoid this misunderstanding

Several small loops are invalid even if clues match. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
