Controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Keep the playing area visible while using these controls. A new-round button replaces the current round.
An example to follow
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. Read the matching step again.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. After a move, check what changed. Decide which rule explains the new state before acting again.
