Sudoku, the calm way. Smart Sudoku Zen turns every puzzle into a quiet moment, and every solved puzzle into a stone in your own temple garden. THE JOURNEY Follow Master Sora through spring, summer, autumn and winter. 32 stages, each teaching one solving technique with a puzzle built for exactly that step: from Full House and Hidden Single to X-Wing, Skyscraper, XY-Wing and Swordfish. YOUR GARDEN Earn coins and restore a forgotten zen garden piece by piece: raked gravel, moss, a koi pond with a red bridge, stone lanterns, a tea house and finally the pagoda. It changes with the seasons, with cherry blossoms, autumn leaves, snow and fireflies on summer nights. HINTS THAT TEACH Stuck? The master shows you the next step and explains why it works, with the pattern highlighted right on the board. Learn 20 techniques instead of guessing. ONE DAILY PUZZLE FOR THE WORLD Every player gets the same puzzle each day: gentle on Mondays, expert on Saturdays, a diagonal on Sundays. Keep your streak, compare your time on the Game Center leaderboard and take on three daily challenges, like finishing all 5s first. EVERY PUZZLE IS FAIR Thousands of verified puzzles with exactly one solution, graded by the techniques they really need, not by the number of empty cells. Play Classic, Diagonal and Windoku. MADE FOR FOCUS • Easy, Medium, Hard and Expert • Explore all 20 techniques with interactive examples, highlighted candidates and connection lines • Notes that tidy themselves, undo and redo • Check against the solution, or only show conflicts for double coins • Jokers and an auto solver that explains every step • Type in or photograph a puzzle from a newspaper, let the solver explain it or play it right away • Game Center: 23 achievements and 7 leaderboards for best times, the daily puzzle, solved puzzles and journey stars • Optional iCloud sync: continue your progress on iPhone and iPad with the same Apple Account • iPhone and iPad, portrait and landscape, keyboard support • Light and dark mode, VoiceOver and Dynamic Type • No ads, calm music Think clear.
