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. Contact us with the game and device if a control does not respond.
A useful 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. Consider the next action carefully.
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
