I have been featured in a Sudoku book. Conceptis Japan made a book for a Japanese publisher, Kasakura Shuppan. In the book they introduce a puzzle friend who has solved four of the puzzles and his/her solving time is revealed beside the puzzle. Chie, the manager of Conceptis Japan, asked me if I knew someone who would like to get introduced there. I decided that I could as well do it myself.
So here are two of the puzzles I had to solve. Solving them as fast as possible was more stressful than I thought. I usually pay no attention to the clock. The hardest one took me 28 minutes!
With the sample books I got this note from Chie :)
When I showed the book to my family, no one was thrilled to have the book with my autograph!
