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. Make the next step deliberately.

Step by step
- Select an editable cell.

Controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Keep the playing area visible while using these controls. Use the visible help when you are unsure of the next input.
A useful example
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Compare this with the rule that governs the move. Choose a deliberate next step.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
