Welcome to the DiAgonizer™!

There is a brand new iPhone Application with lots of these puzzles available in the App Store.
Come back soon! For every puzzle size, you'll get a new puzzle at this website each week ...

On each row, column or (bigger or smaller) diagonal, no number may occur twice.

You can temporarily put two or three numbers in one field as to exclude all others. Good luck!
