How to play
Fill the grid so that every row, every column and every 3×3 box contains the digits 1 to 9 once. That is the only rule. Tap a cell to select it and tap a digit to fill it. Turn on Notes to write small candidates when you are not sure yet, and use Undo if you change your mind.
New to Sudoku? How to play takes you through the rule and the first moves, and Sudoku tips covers the habits that make you faster.
Hints that teach
When you are stuck, the Hint button shows the next logical move and tells you why it works, naming the technique. Over time you stop needing it. Every technique the game uses has its own guide with a real example, from hidden singles to the X-Wing.

Sudoku Clan runs in the browser on phones, tablets and computers. There is nothing to install, and you do not need an account. You can add it to your home screen, and solo puzzles keep working without a connection once the game has loaded. Sign in if you want your progress on more than one device.
