Work through an 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. Choose a deliberate next step.
A common point of confusion
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Read the feedback to see why an action did not have the expected result. 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.
