See how the rules apply
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. 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. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
