See the idea in action
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Focus on why the action is allowed, not only its outcome. Look for the relevant detail.
A mistake to avoid
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.
