The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Compare this with the rule that governs the move. Notice the change in the playing area.
Avoid this misunderstanding
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
