Just starting out? These sites have the clearest interfaces, best hint systems, and most beginner-friendly difficulty settings.
Beginners need three things: a clean grid that's easy to read on any screen, a hint system that explains why a number goes somewhere rather than just placing it, and a proper Easy difficulty that genuinely is easy — not "easy compared to Expert." All sites on this list tick these boxes.
