Sudoku is a puzzle, which is a 9 by 9 square, each of which contains a number from 1 to 9. There cannot be identical numbers in one column, row or 3 by 3 square. Initially, only a fraction of the numbers are shown. The goal is to find the missing ones. All Sudoku on our site are composed correctly and have the only correct solution! It is absolutely free to play Sudoku online!

Each cell contains auxiliary numbers to facilitate the solution. Each number can be marked as a possible variant of the correct value for the cell by highlighting it in black (with the left mouse button), or erased to exclude the variant from the list of errors (right mouse button).
