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. The example below illustrates a decision.
The playing sequence
- 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.
How to interact with the game
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Use the control method described here for this activity. Make sure you are interacting with the game rather than the surrounding page.
Work through an 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. Choose a deliberate next step.
A common point of confusion
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
