The unsolved Sudoku puzzle supplies only a few numbers in random squares. To solve the puzzle, the remaining squares must be filled in with the numbers 1 through 9, each appearing only once in each row, column and 3x3 square.Operating system: Win95,Win98,WinME,Windows2000,WinXP,Windows2003 Release notes: New Release
