An example to follow
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Compare this with the rule that governs the move. Read the matching step again.
Where a round can go wrong
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. 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.
