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. Look at the feedback after the action.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Use the example as a guide rather than a substitute for reading your board. Keep the game’s format in mind.
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
