Try a more deliberate round
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. Use the example to check your reasoning.
What counts as success
Fill each row, column and irregular coloured nine-cell region with 1–9 once. The feedback beside the game helps you follow the round. 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.
Controls
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. Use one clear input at a time.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Use the example as a guide rather than a substitute for reading your board. 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. Take a moment to reassess the position before continuing. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
