Your goal
Fill each row, column and irregular coloured nine-cell region with 1–9 once. The feedback beside the game helps you follow the round. The example below illustrates a decision.
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. 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. 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. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
