A careful first round

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Use the example to check your reasoning.

Your goal

Fill each row, column and irregular coloured nine-cell region with 1–9 once. Keep that objective in view throughout the round. 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. On a smaller screen, keep the active part of the board within view. Look at the feedback after the action.

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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
