Ten 4×4 loop puzzles with all cell clues shown.
Try a deliberate move
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
Your goal
Draw one closed loop whose edges match the count around every numbered cell. An attractive position is not enough unless the goal is met. 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. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.
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. Notice the change in the playing area.
Watch out for this
Several small loops are invalid even if clues match. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
