Learn from a sample situation
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.
A common point of confusion
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
