See how the rules apply
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Apply the same reasoning to the position in your own round. Keep the game’s format in mind.
Notice this detail
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Read the feedback to see why an action did not have the expected result. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
