About the Game

Sudoku is a numbers puzzle game which popularity has recently spread all over the world.

While the name Sudoku or Su Doku is said to be a contraction of the Japanese phrase suji wa dokushinsha ni kaiguru meaning something like solitary number, the game itself may have evolved from number puzzles described by the 18. century mathematician Euler (1707 - 1783).

This version of Sudoku is played in a 3 by 3 grid of blocks, each block displaying the numbers from 1 to 9 in a 3 by 3 grid of cells.

The rules are simple, fill all empty cells so that the numbers 1 to 9 appears once in each row, column and block.
