A useful example
A circle 7 may have an arrow containing 3 and 4 when the normal Sudoku rules also allow it. Compare this with the rule that governs the move. 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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
