One way to understand the rules
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. Choose a deliberate next step.
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
