The playing sequence
- 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.

Making selections and moves
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Read a button’s label before selecting it. Avoid pressing the same control repeatedly while a move is being processed.
Try this example
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Focus on why the action is allowed, not only its outcome. Keep the controls nearby.
Where a round can go wrong
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
