Puzzle Lab

Puzzle Lab is a calm, distraction-free jigsaw game. Pick one of the built-in photos or import any picture from your library, choose a shape (classic / circle / hexagon) and a difficulty (9 to 400 pieces), and drop pieces into place. Pieces snap when they're close, you can filter to just edge pieces to start with the border, and a quick tap shows the reference image whenever you're stuck. A daily challenge reseeds every day for a quick session. Optional white noise and two ambient tracks help you focus. Time, move count and 20+ achievements are saved locally. Everything is offline. No accounts, no ads, no tracking, no network. The photos you import never leave your device.
