Put the rules into context

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. Take a moment to compare.

Keep this in mind

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
