Sudoku Online

About this game

Fill the 9×9 grid so every row, column and box holds each digit once, using logic alone, since each puzzle has exactly one solution. The classic mode comes in four difficulty levels, from Easy to Expert, and extra modes bend the rules with diagonals, bonus regions, target sums or markers between neighboring cells. Leaderboards, personal stats and a chat let you compare results and swap tips with other players.

How to play

Fill every empty cell with a digit between 1 and 9, and never repeat a digit in any row, column or 3×3 box. Select a cell to enter a digit, and use notes mode to jot down candidates while you narrow things down.
