Sudoku

About the game

Fill the 9×9 grid so every row, every column and every 3×3 box has the numbers 1 to 9, with no repeats. Four levels from Easy to Expert, a fresh grid every game and a Daily challenge that is the same for everyone, with notes, undo and hints when you get stuck. Play with mouse, keyboard or touch, right in the browser.

How to play Sudoku

1. A Sudoku board is a 9×9 grid split into nine 3×3 boxes. Some numbers are already filled in.
2. Fill the empty cells with numbers from 1 to 9: every row, every column and every 3×3 box must hold all the numbers from 1 to 9, with no repeats.
3. Every grid has a single solution, and you can reach it with logic alone, no guessing.
4. Pick a level: Easy, Medium, Hard or Expert. Each game deals a new grid, and the Daily challenge is the same grid for everyone.

Tips

• Start with the rows, columns and boxes that are almost full: with few empty cells, the missing numbers show up fast.
• For each number, check where it can still go in a box. If only one cell is left, that is its place.
• Use notes to mark the candidates of each cell. When a cell is down to one candidate, fill it in.
• Stuck? Ask for a hint or undo your last moves. Wrong numbers turn red.
