Who am I?

I’m Stefan Heine and Im Germanys best-known puzzle maker. I have been supplying over 300 newspapers and magazines from all over the world with brain teasers of all kinds for more than 20 years. I have been making Sudoku puzzles since 1999, and it is said that I’m the one responsible for their success in Germany.

I created the puzzles for the German, Austrian, and American championships, and also for the World championships. I advise television shows and agencies on issues related to puzzles, manage puzzle magazines, design and develop games, give workshops, and create puzzle books for many publishers.

I do what I can do best: Puzzles, puzzles, puzzles!

                         Sincerely, Stefan Heine
