This collection contains 6 puzzles. Progress is saved in this browser. The same puzzle can appear again; the collection is not labelled with calibrated difficulty levels.

Focus on one rule

Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Notice the feedback after each input.

Your goal

Fill each row, column and irregular coloured nine-cell region with 1–9 once. Keep that objective in view throughout the round. Take a moment to understand the current position.

Step by step

1. Select an editable cell.
2. Enter a value using the keypad or keyboard; Notes stores candidates.
3. Read the region, cage, arrow or outside clues alongside the normal constraints.
4. Check entries verifies the completed board; Undo reverses your last input.
5. 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. Look at the feedback after the action.

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. Take a moment to compare.

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. 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.
