Lucido Sudoku is the cleanest, most thoughtful Sudoku experience on iPhone and iPad. Every puzzle is generated using real human solving techniques — the same logic you use when you play. That means difficulty ratings are meaningful, and hints actually teach you something. WHY LUCIDO? Most Sudoku apps use brute-force puzzle generation. Lucido uses technique-based solving — Naked Singles, Hidden Singles, Naked Pairs, Locked Candidates, and X-Wing patterns — so every puzzle is fair, graded accurately, and solvable by logic alone. FEATURES • Five difficulty levels — Beginner to Expert • Daily Challenge — one fresh puzzle every day, the same for every player worldwide • Progressive hints — four levels from gentle nudge to full reveal • Candidate notes — jot down possibilities, cleared automatically as you solve • Unlimited undo — step back through any move, no restart needed • Stats & streaks — track your best times and hint-free completions per difficulty • Timer — optional, hide it if you prefer a relaxed pace HINTS THAT TEACH Tap Hint once for a nudge. Tap again to focus on the right area. Tap again for a technique explanation. One more tap reveals the answer. You decide how much help you want. DAILY CHALLENGE A new puzzle resets at midnight.
