How to interact with the game
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. Return to the rules if the result is unexpected.
Learn from a sample situation
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. Take a moment to compare.
Avoid this misunderstanding
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Read the feedback to see why an action did not have the expected result. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
