Built for the bigger platform

Smart learning

Hints and explanations should teach the next logical step, not just reveal answers.

Android connected

The site is designed to support Android challenge links, QR transfer, and scanned puzzles.

Lightweight sync

Progress will sync through explicit checkpoints instead of costly move-by-move writes.

Scanner path

Android remains the strongest OCR scanner first, with web upload and camera import later.
