Choosing and moving on screen
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. On a smaller screen, keep the active part of the board within view. 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. Apply the same reasoning to the position in your own round. Read the matching step again.
Keep this in mind
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.
