A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Refer to the controls when needed.
Your goal
Fill each row, column and irregular coloured nine-cell region with 1–9 once. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.
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 careful first action helps you become familiar with the layout. Return to the rules if the result is unexpected.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Apply the same reasoning to the position in your own round. Notice the change in the playing area.
Watch out for this
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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
