A small practice goal
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.
What you are aiming for
Fill each row, column and irregular coloured nine-cell region with 1–9 once. Keep that objective in view throughout the round. Start with a deliberate move.
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.
Making selections and moves
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. Read the example below alongside these instructions.
An example to follow
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Compare this with the rule that governs the move. 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. Check the rule before repeating the action. 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.
