Getting comfortable with the controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. A careful first action helps you become familiar with the layout. Make sure you are interacting with the game rather than the surrounding page.
See how the rules apply
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. Verify the rule before continuing.
Keep this in mind
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
