Sudoku?

Lately I have heard a lot about Sudoku and how people can spend hours and hours passing the day filling in numbers in little boxes. The rules seem easy: Fill all empty squares so that the numbers 1 through 9 appear once in each row, column and 3x3 box. Maybe I will learn how to play and see what all the fuss is about???

Anyway...for all you Sudoku fans out there, I bring to you a very special puzzle. The world's hardest Sudoku puzzle courtesy of Zonked Yak: AL Escargot.

The puzzle has also gone by the name "AI Etana"

So is it the world's hardest? Come on experts, let me know your thoughts...
