Sudoku

A new puzzle every day, and everyone gets the same one. Pick a level and go.

How the daily works

Every day at midnight, your time, there are four new puzzles: easy, medium, hard and expert. Everyone gets the same ones, so you can compare times with a friend.

Easy puzzles only need the basics. Medium adds pairs. Hard needs an X-Wing somewhere, and expert needs a swordfish. When you get stuck, the hint shows you one move and tells you the name of the trick behind it.

There are no ads and nothing to sign up for. Your streak and your progress stay on your device.
