The controls to know
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. Look at the feedback after the action.
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. Read the matching step again.
A mistake to avoid
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
