A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Notice the feedback after each input.
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
- Select an editable cell.
- Enter a value using the keypad or keyboard; Notes stores candidates.
- Read the region, cage, arrow or outside clues alongside the normal constraints.
- Check entries verifies the completed board; Undo reverses your last input.
- 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. Keep the playing area visible while using these controls. Avoid pressing the same control repeatedly while a move is being processed.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Apply the same reasoning to the position in your own round. Look for the relevant detail.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
