The Evolution of Sudoku: From Newspapers to Online Puzzles

June 28, 2025

Sudoku has become one of the most recognizable and beloved puzzles in the world. But it didn’t start out as the sleek, tap-and-play digital experience we know today. In fact, the history of Sudoku is a winding story of mathematics, print media, and modern technology.

In this post, we take a journey through time—from the origins of Sudoku to its transformation into a digital favorite.


1. Sudoku’s Surprising Origins: Not from Japan

While the name Sudoku is Japanese, the puzzle’s roots can actually be traced back to 18th-century Switzerland. A mathematician named Leonhard Euler developed a concept known as Latin Squares, which required filling a grid so that numbers or symbols appeared only once in each row and column.

This idea eventually inspired American puzzle creator Howard Garns, who developed a number puzzle called “Number Place” in the late 1970s. It appeared in Dell Pencil Puzzles and Word Games in the U.S.


2. The Japanese Influence: Naming and Popularizing

In 1984, a Japanese puzzle company called Nikoli discovered “Number Place” and introduced it to the Japanese public under a new name:
🎌 Su-doku, short for “Sūji wa dokushin ni kagiru” (数字は独身に限る), which loosely translates to “the digits must remain single.”

Nikoli refined the rules (such as limiting the number of given clues to increase difficulty) and published it in magazines, where it became a national obsession.


3. Global Boom: The 2005 Puzzle Craze

Sudoku remained a Japanese phenomenon for two decades until it exploded worldwide in 2005, thanks to a New Zealand judge named Wayne Gould. He developed a computer program to generate Sudoku puzzles and pitched them to The Times of London.

The Times published Sudoku on the front page—and within weeks, it was syndicated across hundreds of newspapers globally. Suddenly, Sudoku was everywhere: printed in dailies, available in books, and played by commuters and puzzle enthusiasts around the world.


4. Digital Shift: Sudoku Enters the Online Era

With the rise of smartphones and web-based gaming, Sudoku naturally found a new home online. Now, millions of users play Sudoku on:

  • Mobile apps
  • Dedicated puzzle websites
  • Social platforms and browser games

Online Sudoku brought new features:
