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. Avoid pressing the same control repeatedly while a move is being processed.
Follow the example
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Compare this with the rule that governs the move. Keep the controls nearby.
One detail worth checking
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
