Focus on one rule

Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.

Your goal

Fill each row, column and irregular coloured nine-cell region with 1–9 once. Use the instructions to see which actions move you towards it. Keep the controls in easy reach.

Step by step

1. Select an editable cell.
2. Enter a value using the keypad or keyboard; Notes stores candidates.
3. Read the region, cage, arrow or outside clues alongside the normal constraints.
4. Check entries verifies the completed board; Undo reverses your last input.
5. New puzzle selects another included puzzle.

Controls

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. Check any mode label before starting.

A useful example

The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Use the example as a guide rather than a substitute for reading your board. Verify the rule before continuing.

Watch out for this

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
