Take a closer look while playing
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
What counts as success
Draw one closed loop whose edges match the count around every numbered cell. Use the instructions to see which actions move you towards it. Return to the instructions when a step is unclear.
The order of play
- 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.
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. A careful first action helps you become familiar with the layout. Use one clear input at a time.
A useful example
A 0 cell has no loop edge around it; a 3 has exactly three. Compare this with the rule that governs the move. Keep the controls nearby.
A mistake to avoid
Several small loops are invalid even if clues match. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
