A useful example
A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
