Fun sudoku game featuring genuine Sudoku Generator
4Sudoku is a number placement game which requires great patience and a good logical thinking ability! The aim of the game is to place a numerical digit 1-9 in each cell of the 9x9 grid so that each row column and 3x3 block contain only one instance of each number.
