Build a steady rhythm
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Notice the feedback after each input.
Your goal
Draw one closed loop whose edges match the count around every numbered cell. Use the instructions to see which actions move you towards it. Try to explain the aim in your own words.
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. Keep the playing area visible while using these controls. Use the visible help when you are unsure of the next input.
A useful 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. Keep the game’s format in mind.
Watch out for this
Several small loops are invalid even if clues match. Compare the situation with the worked example. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
