Choosing and moving on screen
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.
Follow the example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Compare this with the rule that governs the move. Notice the change in the playing area.
Notice this detail
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. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
