Ten 4×4 loop puzzles with all cell clues shown.
A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Use the example to check your reasoning.
Your goal
Draw one closed loop whose edges match the count around every numbered cell. Read that aim before choosing your first action. 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. Read the example below alongside these instructions.
A useful example
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. Read the matching step again.
Watch out for this
Several small loops are invalid even if clues match. Take a moment to reassess the position before continuing. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
