Make the controls familiar

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Keep the objective visible.

Your goal

Fill each row, column and irregular coloured nine-cell region with 1–9 once. An attractive position is not enough unless the goal is met. Take a moment to understand the current position.

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. On a smaller screen, keep the active part of the board within view. Use one clear input at a time.

A useful example

The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.

Watch out for this

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