Question

fill in the grid with digit in such a manner that every row, every column and every 3x3 box accommodates the digits 1-9, without repeating any

Answer 1

Answer:

Write 1 to 9 digits in an empty Sudoku table with these rules (similar to 9-Queen problem):

There are 9 Boxes indexed from 1 to 9 in the image below. and each box has a 3x3 grid child.

Every two digits should NOT be in the same row, column or diagonal.

Pointing rule: You have to place next number in an specific box. (e.g. if you start to place 1 in top-left box and middle-center child grid, you have to continue with 2 in middle-center box)

You are free to begin from any box.

Close the loop: The last number (9) should point to the box that you have placed the first number (1) in it.

At the end there will be a Sudoku table with only 9 digits in it each in a separate 3x3 box. (other 72 cells will remain empty)
