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.
