Every board is a working QR code. Tap a light area and it fills in dark. That corrupts the data, but the code keeps scanning right up to the Reed-Solomon error correction limit. Your score is how many moves you make before it breaks. A solver finds the exact maximum for each puzzle, so a perfect game is a real target. Four difficulty levels change only what you see. A bigger code on Sundays. Free, no account, no cookies, no analytics scripts. Scan any board mid-game and it opens that puzzle.

Could you build this?
Partial The QR-based puzzle UI and rendering are vibe-codeable with QR libraries, but computing the exact optimal move count requires a non-trivial search or optimization solver.
What it would actually take: The game needs a correct QR encoder with Reed-Solomon decoding limits and a daily puzzle generator. The exact maximum per board is a hard combinatorial search that needs branch-and-bound or similar pruning, which benefits from algorithms expertise. Validating solutions at scale takes careful testing.
