Review a difficult moment
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Make the next step deliberately.
Your goal
Draw one closed loop whose edges match the count around every numbered cell. Read that aim before choosing your first action. Follow this game’s rules rather than another version’s.
Step by step
- 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.
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. A new-round button replaces the current round.
A useful example
A 0 cell has no loop edge around it; a 3 has exactly three. Use the example as a guide rather than a substitute for reading your board. Take a moment to compare.
Watch out for this
Several small loops are invalid even if clues match. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
