Many beginners told me that the Sudokus uploaded on the blog are quite difficult for them to solve. So, I decided that from now on wards I'll also post a link of the easier version of the same Sudoku which I post on the blog. Additionally, from now on wards I'll also post the link of  the solution of the Sudoku.(I'll also add the solution link to the previous Sudokus in some days)

Sudoku 10: Missile Sudoku

Today I've created a new variant---Missile Sudoku as a tribute to Dr. A. P. J. Abdul Kalam, the Missile Man of India, on the occasion of his 87th birth anniversary.
Rules: Classic Sudoku rules apply. Additionally the cells with circles are missile cells. The number in the missile cell must be greater than the numbers in the adjacent(both orthogonally and diagonally) cells.

I hope many variations of this variant will appear in future😉
