What is Nikoli?

The first puzzle magazine in Japan was published in August, 1980, this magazine was "Nikoli." So, yes, we are the pioneers in this field in Japan. Nikoli is now the company "NIKOLI Co., Ltd."

Since that first magazine, we have been publishing puzzle magazines and books and supplying original puzzles to other publications (newspapers, weekly and monthly magazines). We are constantly studying and inventing new puzzles and have created over 200 kinds of original puzzles.

We confidently assure you that among Japanese puzzle solvers, Nikoli stands for fantastic puzzles.
