Getting comfortable with 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. On a smaller screen, keep the active part of the board within view. Contact us with the game and device if a control does not respond.
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. Keep the controls nearby.
Check this before moving on
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.
