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

Try a more deliberate round

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.

The challenge in front of you

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.

The order of play

  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. Use the control method described here for this activity. Return to the rules if the result is unexpected.

Put the rules into context

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. Take a moment to compare.

Where a round can go wrong

Several small loops are invalid even if clues match. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
