Your goal
Draw one closed loop whose edges match the count around every numbered cell. The feedback beside the game helps you follow the round. Notice how the game responds to your input.
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.
Keyboard and screen controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Look at the feedback after the action.
Put the rules into context
A 0 cell has no loop edge around it; a 3 has exactly three. Your next round may have a different position, so inspect it before acting. Look for the relevant detail.
An important reminder
Several small loops are invalid even if clues match. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
