Ninefold: Sudoku

Daily logic, honest levels

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

A new sudoku every day, the same for everyone. Levels that mean what they say, and a hint that explains the next step instead of just filling it in. A sudoku that respects your time: every puzzle has exactly one answer, every level is honest, and help is there the moment you need it. Warm up on Easy or go straight to Expert for a real fight. Ninefold sets each puzzle's level by the techniques it takes to solve, not by how many numbers are missing, so Easy stays relaxing and Expert is a genuine challenge. A new puzzle every day. One daily sudoku, the same for every player: gentle on Monday, tough by Saturday. Solve it each day to grow your streak, and a streak freeze saves you on the day life gets busy. Hints that make you better. Stuck? Tap Hint and Ninefold shows you where to look and explains the step in plain words. Tap again if you just want the answer. You pick up techniques like pairs and X-wings without reading a manual. New to sudoku? A short hands-on tutorial shows you the goal and walks you through your first move. You're playing in under a minute. Made for focus. • Pure logic: no guessing is ever needed. • Four levels (Easy, Medium, Hard, Expert) with unlimited puzzles. • Pencil marks that clean themselves up as you play. • Unlimited undo, optional mistake highlighting, and a timer you can pause. • Your fastest times and averages for every level. • Saves automatically: close it mid-puzzle and pick up later. • Plays offline, on phone and tablet, in 26 languages. No sign-up needed. Your puzzles, times and streak never leave your phone. Sharpen your mind a few minutes a day. Get Ninefold and solve today's puzzle.

Daily reminders, if you want them: Ninefold can let you know once a day when the new puzzle is ready. You choose the time, there is never more than one a day, and you can turn them off any time in Settings. Also a few small improvements.
