A useful example
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Use the example as a guide rather than a substitute for reading your board. Check the stated objective.
Watch out for this
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
