When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Notice the feedback after each input.
Aim for this result
Draw one closed loop whose edges match the count around every numbered cell. Use the instructions to see which actions move you towards it. Notice how the game responds to your input.
Work through the instructions
- 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. On a smaller screen, keep the active part of the board within view. Check any mode label before starting.
Work through an example
A 0 cell has no loop edge around it; a 3 has exactly three. Apply the same reasoning to the position in your own round. Choose a deliberate next step.
A common point of confusion
Several small loops are invalid even if clues match. Check the rule before repeating the action. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
