About Sudoku

Sudoku Master is the number puzzle the whole world knows: place the digits 1 to 9 so that each row, each column and each 3×3 box contains every digit exactly once. Multiple difficulty levels take you from a quick warm-up to a proper logic challenge.

A hosted HTML5 game that runs in your browser when you press play.

How to play

  1. Pick a difficulty to deal a fresh grid.
  2. Each row, column and 3×3 box must contain 1–9 with no repeats.
  3. Place the digits you're certain of, then narrow down the rest.
  4. Use pencil marks for candidates until a cell is forced.

Tips & strategy

  • Scan for cells where only one digit can possibly fit.
  • Work the rows, columns and boxes that are already nearly full.
  • Pencil in candidates — elimination does most of the work.
