The logic puzzle challenges people to fill a grid of 9×9 blocks, with nine boxes in each block so that all columns, vertical and horizontal, contain the numbers one to nine without repetition. The number of filled-in figures for a grid at the start of the puzzle determines how difficult it is.

“Known as the Godfather of Sudoku, he was adored by puzzle lovers around the world and we would like to express our gratitude to all of you,” his company, Nikoli, said on its website on Monday.

Sudoku became popular outside Japan about 20 years ago after overseas newspapers began printing it. Praised as a way to keep mental faculties sharp, more than 100 million people worldwide are estimated to try the puzzles regularly. A world championship has been held annually since 2006.

Kaji continued to create and refine puzzles with the help of readers of his quarterly puzzle magazine. He stepped down as head of his company in July due to ill health and died on August 10.

“I get really moved when I see a new idea for a puzzle which has lots of potentials,” he told the BBC in 2007, adding that the secret to inventing a good puzzle was to make the rules simple.

“It is like finding treasure. It’s not about whether it will make money, it is purely the excitement of trying to solve it.”
