A practical guide to Slitherlink
Try Slitherlink at your own pace and keep its objective in view. Draw one closed loop whose edges match the count around every numbered cell. Check the relevant rule before repeating a move. Begin with the solo mode shown on the page. Choose a clear next step rather than rushing through the instructions.
Ten 4×4 loop puzzles with all cell clues shown.
Something to practise
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
The objective of a round
Draw one closed loop whose edges match the count around every numbered cell. The feedback beside the game helps you follow the round. Take a moment to understand the current position.
Start here and follow along
- 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.
Put the rules into context
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. Look for the relevant detail.
Pay attention to this rule
Several small loops are invalid even if clues match. Compare the situation with the worked example. After a move, check what changed. Decide which rule explains the new state before acting again.
