Rules of Anti Diagonal Sudoku Puzzle
Place a digit from 1 to 9 into each of the empty cells so that each digit appears exactly once in each row, column and 3x3 outlined box. Additionally every main/marked diagonal contains only 3 different numbers (e.g. 1,2,6).

Solution:
The rule of Anti Diagonal Sudoku is that each main diagonal must contain only three different digits. In a standard 9x9 Sudoku grid, there are two main diagonals:
The first diagonal runs from the top left corner to the bottom right corner.
The second diagonal runs from the top right corner to the bottom left corner.
So, in an Anti Diagonal Sudoku puzzle, no digit can appear more than twice in any of the main diagonals.
The other rules of Sudoku still apply in Anti Diagonal Sudoku. This means that each row, column, and 3x3 block must also contain the numbers from 1 to 9, without repetitions.
Anti Diagonal Sudoku can be a more challenging puzzle than regular Sudoku, because there are fewer places where you can put certain numbers. However, it can also be a more rewarding puzzle to solve, because it requires more strategic thinking.
Here are some tips for solving Anti Diagonal Sudoku puzzles:
Start by filling in the numbers that you know for sure. This will help you to narrow down the possibilities for the other numbers.
Look for patterns and sequences in the grid. This can help you to identify which numbers are likely to be in certain places.
Use the elimination method to rule out impossible solutions. If a number cannot appear in a certain row, column, or block, then it cannot appear in either of the main diagonals either.
Be patient and persistent. Anti Diagonal Sudoku puzzles can be difficult, but they are definitely possible to solve.
