Practice beyond the first move

What the game asks you to do
Fill rows, columns and boxes with 1–9 once. Cage digits cannot repeat and must add to their clue. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.

Your inputs
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Read a button’s label before selecting it. A new-round button replaces the current round.
Put the rules into context
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
