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. Check the stated objective.
Avoid this misunderstanding
Several small loops are invalid even if clues match. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
