The basic idea behind Greater Than Sudoku and it works likethe standard Sudoku in most instances.
There is still a grid of 9 x 9 squares, the grid will further be divided into 9 subgroups of 3 x 3 squares each.
However in Greater Than Sudoku between two blocks in a subgroup, there will be a greater than or less than sign indicating the order of the numbers in the squares. The object of this game is to complete all the squares with numbers 1 - 9 where the numbers in each row, column or subgroup must not repeat, and that the numbers must obey the relationship given by the signs.
The faster you finish this game, the higher your score. If you are stuck, you can click the hint button to get some hint, but a time penalty will be applied.
Greater Than Sudoku is a tough nut to crack, but give it a go and put your grey matter to the test in a big way.
