Sudoku Zero

Classic Sudoku, daily puzzles

Free · Designed for iPad. Not verified for macOS.

Classic Sudoku with nothing in the way: no accounts, no interruptions, no clutter. Play offline, or take on a fresh Daily Challenge every day. Sudoku. Nothing else. Sudoku Zero is classic 9×9 Sudoku with everything else taken out. No ads, no subscriptions, no in-app purchases, no accounts, no tracking, and no popups asking for anything. FOUR LEVELS, PROPERLY GRADED Easy, Medium, Hard and Expert are graded by the techniques a puzzle actually needs, not just by how many numbers are given. Every puzzle has exactly one solution and can be solved by logic alone: no guessing. DAILY CHALLENGE A new Hard or Expert puzzle every day, the same for everyone. Keep your streak by finishing each day's puzzle on its own day, and use the calendar to go back and play any day you missed. Missed days count as completed, but they can't repair a broken streak. WORKS OFFLINE Regular games are created on your device and never need a connection. The Daily Challenge is saved once it has downloaded. HELPFUL, NOT PUSHY • Notes in their natural positions in each cell • Undo and redo • Logical hints that explain the technique, such as "Look at row 7. Only one cell can contain 4." • Optional mistake highlighting, with a mistakes counter • Highlights for related cells and matching numbers • A gentle ripple when you finish a row, column, box or all nine of a number • Automatic saving, so you can pick up exactly where you left off STATISTICS THAT MEAN SOMETHING Games started and completed, best and average times, games finished without a single mistake, and your current and longest Daily Challenge streaks. PRIVATE BY DESIGN No personal data is collected. Your games, statistics and streaks stay on your device. MADE TO BE COMFORTABLE Light and Dark Mode, Dynamic Type, and haptics and sounds you can switch off. Works on iPhone and iPad. Zero ads. Zero subscriptions. Zero interruptions.
