About the Author
My name is Serhii Kucher.
I have been creating logic puzzles professionally since 1998 and currently work as the Editor-in-Chief of the Japanese puzzle magazine Relax.
I am the author of numerous puzzle books and the creator of a wide range of logic puzzles, including Sudoku, Nonograms (Picross), and other original puzzle variants. My goal is to design puzzles that are both intellectually challenging and enjoyable for solvers of all skill levels.
If you enjoyed my puzzle books, I would greatly appreciate it if you could leave a review — your feedback helps improve future editions and supports independent puzzle creators.
If you have any questions about solving a puzzle or would like to share your thoughts, feel free to contact me.
