Arto Inkala, a Finnish mathematician, claims to have created the most difficult Sudoku puzzle yet. According to Inkala, it took him three months to finish the construction of the puzzle.
Sudoku is a number placement puzzle. The objective of the player is to fill a 9 x 9 grid with numbers from 1 to 9 so that each column, row, and block (3 x 3 sub grids) contains all the digits. The puzzle was popularized by the Japanese company Nikoli in 1986.

This is purely an annoying sudoku. You can call it “difficult” if you want, but to me “difficult” means that there are human-reachable steps that are hard to find. As far as I can tell (and my sudoku-solving software, and one or two other people’s that I’ve tried), there’s nothing to do here except a lot of guess-and-check to eliminate possibilities. This is not at all like a good hard Nikoli puzzle.

You’re right. Looks like it will take me eternity before I can solve this.
Step one, take a picture of the sudoku using Google Goggles.
Step two, press “solve sudoku”.
There is no step three.
I also frequently read the last pages of books first.
@pfooti
haha… Same here. Don’t really have time to spend hours solving a single sudoku puzzle. Besides, it’s too many guesses and checks.
I was about to print and attempt. Alas, reading the comments, I might not even try it. *sigh*
@Bon,
There’s no harm in trying.
I haven’t solved it yet. LOL.
