A useful example
A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Focus on why the action is allowed, not only its outcome. Verify the rule before continuing.
Watch out for this
A correct cage total does not permit duplicate digits in a row. Take a moment to reassess the position before continuing. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
