Bring this focus to a round
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Use the example to check your reasoning.
What the game asks you to do
Fill each row, column and irregular coloured nine-cell region with 1–9 once. An attractive position is not enough unless the goal is met. Notice how the game responds to your input.
A walkthrough of the rules
- 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.
Using the playing area
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. On a smaller screen, keep the active part of the board within view. A new-round button replaces the current round.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Compare this with the rule that governs the move. Keep the game’s format in mind.
Notice this detail
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. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
