Input guidance
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. Use the visible help when you are unsure of the next input.
Follow the example
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Your next round may have a different position, so inspect it before acting. Check the stated objective.
A common point of confusion
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. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
