Coolest sudoku EVAR!

Recommended Posts

I'm not the world's biggest sudoku guy. In fact, I rarely do sudokus. But I stumbled across a YouTube video that featured someone solving this sudoku, which, let's face it, is extraordinarily cool. You are given only four digits to start, along with three additional rules:

1. The major diagonals are 123456789 (not in order, just that they include all the digits, just like rows and columns)
2. The middle 3x3 square is a magic square (i.e. each of the rows, columns, and major diagonals adds up to the same amount)
3. There is a "knight's move" constraint which says that no digit can be a knight's move (L-shaped move, two boxes along a row or column and then one box perpendicular to that) away from itself.

I'm just amazed at some of the things people come up with. Very clever.

BTW, here's the video of the solution, in case you want to see it solved but don't want to (or can't) solve it.
