Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Keep the objective visible.
Your objective
Fill each row, column and irregular coloured nine-cell region with 1–9 once. The feedback beside the game helps you follow the round. 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.
Making selections and moves
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. A new-round button replaces the current round.
Try this example
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. Notice the change in the playing area.
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
