A few years back, I thought to write a computer program to generate Sudoku puzzles. I started creating it starting with a small size without a smaller grid and with diagonal constraints and called it Sudoku 2D. Created a few Sudoku puzzles using this program and later improved it to increase the size of Sudoku. Unfortunately, later my computer's hard disk crashed taking away my program and a lot of my work. Here I am putting some computer-generated Sudoku 2D puzzles created that time as the 14th contribution to the Fun With Sudoku Series.
Meanwhile, 9/9 is announced as Sudoku Day by World Puzzle Federation, and to celebrate Sudoku Day Logic Masters India is hosting Sudoku Test from 6th September 2014 to 9th September 2014 named as Sudoku Day - LMI September Sudoku Test. Try to participate in this test if you love to solve Sudoku puzzles.

## Rules of Sudoku 2D

Enter the number from 1 to N where N is the size of Sudoku, so that each row, each column, and each main diagonal contains each number exactly once.
