Sydoku: Daily Sudoku Puzzles
No ads, no tracking, just play
Free · Designed for iPad. Not verified for macOS.
New: Contemplative, a fourth difficulty for patient solvers. Fewer numbers, deeper reasoning, and its own daily puzzle, the same for everyone.
Sydoku is Sudoku the way it should feel: calm, clear, and entirely yours.
No ads. No tracking. No distractions. Just puzzles, done right.
A NEW PUZZLE EVERY DAY
Each day brings a fresh daily puzzle in every difficulty, and it's the same puzzle for everyone. Finish on consecutive days to build your streak, or complete Gentle, Standard and Challenging in one day for a Perfect Day.
FOUR WAYS TO PLAY
• Gentle: relaxed
• Standard: balanced
• Challenging: deep focus
• Contemplative (new): patience. Fewer numbers, deeper reasoning. Every puzzle needs more than the basic techniques.
Every puzzle has exactly one solution.
HELP THAT DOESN'T SOLVE IT FOR YOU
• Notes, with Add All Notes when you want them filled in
• Hints show what a square could be. They never place a number for you
• Optional error checking, with mistake limits of 3, 5 or 10, or none at all
• 50 steps of undo and redo
DESIGNED WITH CARE
• Seven themes, including Blossom, Midnight, Ocean and Classic
• Scales beautifully on iPhone and iPad
• Respects Dynamic Type and accessibility settings
• Statistics, best times and a full puzzle history
• Seamless iCloud sync. Start on your iPhone, finish on your iPad
HONEST BY DESIGN
Sydoku is free and open source, and collects no data at all. Nothing to sell you, ever.
Built by someone who just wanted a better Sudoku app.
New difficulty: Contemplative
For when Challenging isn't enough. Contemplative puzzles use as few clues as each puzzle allows, and every one needs deeper reasoning to solve. It has its own daily puzzle too, the same for everyone.
Also new:
• How to Play, from the (?) button or the Menu
• Deleting a puzzle from Puzzle History now asks first
• Faster puzzle generation for every difficulty
• Bug fixes and polish
