An example before you play
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. Notice the change in the playing area.
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. After a move, check what changed. Decide which rule explains the new state before acting again.
