A small practice goal
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Use the example to check your reasoning.
The challenge in front of you
Fill each row, column and irregular coloured nine-cell region with 1–9 once. Read that aim before choosing your first action. Follow this game’s rules rather than another version’s.
The order of play
- 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.
The controls to know
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. A careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.
Learn from a sample situation
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Focus on why the action is allowed, not only its outcome. Read the matching step again.
A useful caution
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Read the feedback to see why an action did not have the expected result. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
