Keyboard and screen 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. Use one clear input at a time.
Learn from a sample situation
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Your next round may have a different position, so inspect it before acting. Choose a deliberate next step.
Avoid this misunderstanding
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
