Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Notice the feedback after each input.

The challenge in front of you

Draw one closed loop whose edges match the count around every numbered cell. Read that aim before choosing your first action. Review the board or playing area as it changes.

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.

How to use 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. Look at the feedback after the action.

Work through an 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. Verify the rule before continuing.

A mistake to avoid

Several small loops are invalid even if clues match. A different version of the game may use a different rule. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
