Learn from a sample situation
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Focus on why the action is allowed, not only its outcome. Keep the game’s format in mind.
Check this before moving on
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
