Slitherlink: from controls to your first round
Choose a round of Slitherlink and settle into its rules. Draw one closed loop whose edges match the count around every numbered cell. Look at what changes after your first action. 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.
A small practice goal
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Use the example to check your reasoning.
Understand the aim
Draw one closed loop whose edges match the count around every numbered cell. An attractive position is not enough unless the goal is met. Keep the controls in easy reach.
Work through the instructions
- 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.
Your inputs
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. Look at the feedback after the action.
Work through an example
A 0 cell has no loop edge around it; a 3 has exactly three. Use the example as a guide rather than a substitute for reading your board. Look for the relevant detail.
An important reminder
Several small loops are invalid even if clues match. A different version of the game may use a different rule. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
