Your goal
Fill each row, column and irregular coloured nine-cell region with 1–9 once.
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.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction.
