The order of play

- 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.
Input guidance
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. Use one clear input at a time.
One way to understand the rules
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Compare this with the rule that governs the move. Consider the next action carefully.
A useful caution
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. After a move, check what changed. Decide which rule explains the new state before acting again.
