What is Diagonal Sudoku?
A Sudoku puzzle consists of nine 9×9 squares and your goal is to cover every square with numbers ranging from 1 to 9. For diagonal Sudoku, the main diagonals require to contain the numbers 1 through 9.
Is there a Diagonal Rule in Sudoku?
Frankly speaking, there is no such thing as Diagonal Rule in Sudoku. However, there is a widely played variant of Sudoku in which we have to put all numbers from 1 to 9 into the diagonals.
Is Diagonal Sudoku the hardest?
Many people think that diagonal Sudoku is the hardest form of Sudoku, however, we have explained the rules of Sudoku below and leave it to the readers to determine which Sudoku is the hardest!
Diagonal Sudoku Explained!
Sudoku is a very simple game, which is one of the reasons many people love it:
1. Each column should be numbered 1 to 9 at a time without repeating
2. In each row, numbers 1 to 9 should appear simultaneously without repetition
3. The 3 x 3 circuits should contain the numbers 1 through 9 simultaneously, but not duplicative.
On the sudoku grid, you can find two diagonals of 9 cells. What about those? Do these two diagonals also contain all the numbers from 1 to 9 at the same time?
To put it another way:
Do sudokus go diagonally?
There is no short answer to this question.
There is no rule that says two diagonals of 9 cells must contain the numbers 1 to 9 in standard sudoku.
In most cases, you are not concerned about diagonals unless you are playing this variant or another variant that has a drag rule. Trying to ensure that the numbers 1 to 9 appear only once in the entire diagonal may also be a common puzzling sudoku puzzle.
Does a diagonal rule make Sudoku difficult to solve?
You may think that the absence of a sudoku diagonal rule would mean that the puzzle becomes easier to solve. After all, it is only natural to think that a few issues have a lot of potentials.
However, sudoku is a game in which you have to eliminate the possibility of all digits from a particular cell except one digit.
An additional obstacle means that you may have more details to work with when trying to figure out which digit enters one of the cells in any of the longer diagonals.

Summary of Basic Rules for Diagonal Sudoku
The basic rules of this Sudoku are the same as those of standard Sudoku:
1. Each column, row, and 3×3 sub-grid should be numbered 1 to 9.
2. No column, row, or sub-grid can have two cells with the same number.
The puzzle can be solved with the help of identifying numbers which are small numbers written next to the arrows in the intersections between the cells.
Each identification number is a two-digit product in two cells adjacent to each other. The shape of each pair of adjacent squares shown is indicated by arrows.
For instance, a box at the bottom left with 24 in it means that the cells indicated by the arrow can have a possible number as 3 and 8, 8 and 3, 4 and 6, or 6 and 4.
