THE PLAYBOOK · CFPPAXLB
Getting started with Slitherlink
Use a short break to learn the rhythm of Slitherlink. Draw one closed loop whose edges match the count around every numbered cell. Choose a clear next step rather than rushing through the instructions. Choose a comfortable screen position before beginning. Check the relevant rule before repeating a move.
Ten 4×4 loop puzzles with all cell clues shown.
One thing to notice as you play
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.
What counts as success
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.
The playing sequence
- 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.
How to use the 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. Make sure you are interacting with the game rather than the surrounding page.
An example before you play
A 0 cell has no loop edge around it; a 3 has exactly three. Focus on why the action is allowed, not only its outcome. Consider the next action carefully.
Where a round can go wrong
Several small loops are invalid even if clues match. Compare the situation with the worked example. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
