Mentally rotate and reflect a constellation, then rebuild it in a blank grid.

Deduction: if ◇ + ◇ = 10, then ◇ = 5. The real locks use several clues together. Enter your answer and press Unlock.
Imagination: a dot at the top-left moves to the top-right after a 90° clockwise turn. Apply every instruction in order, then tap the matching positions in your answer grid.
Knowledge: read a clue and choose the concept it describes. Reveal another clue if you need help; this reduces the score, never a life.
Wrong submissions use a life. A third mistake ends a challenge. Practice has no life limit. Knowledge explanations include source links.
