Tracing Sudoku’s Roots
Contrary to popular belief that Sudoku originated from ancient Asia, it’s a relatively recent brainchild. The game’s ancestor, Latin Squares, was the brainchild of Leonhard Euler, a Swiss mathematician from the late 1700s. Fast forward to the modern era, and Howard Garns from Indiana breathed life into the game we recognize today. He introduced it as “Number Place” in 1979, capturing the attention of puzzle aficionados in the magazine “Dell Pencil Puzzles and Word Games.”
By the mid-1980s, this intriguing game found its way to Japan. Here, it was christened “Sudoku,” a name hinting at its unique rule: “the numbers must be solitary.” Given the complexity of creating crossword puzzles in Japanese, Sudoku, with its simple numeric structure, became a sensation. The game’s allure was so strong that Japanese enthusiasts snapped up hundreds of thousands of Sudoku magazines every month.
The global Sudoku wave can be credited to Wayne Gould, a judge from New Zealand. During a Tokyo trip in 1997, he stumbled upon this number puzzle. Recognizing its potential, he reintroduced it to the Western audience. By 2004, renowned newspapers, including the Times of London, were featuring Sudoku puzzles, marking its ascent as a global pastime.
In 2013, recognizing its widespread appeal, the World Puzzle Federation declared September 9th as the official International Sudoku Day, a nod to the game’s 9×9 grid.
Mastering the Game
At its core, Sudoku is a game of logic played on a grid, segmented into smaller grids. The aim? Populate each row, column, and mini grid with numbers from 1 to 9. The catch? No number should appear more than once in any row, column, or grid. While some numbers are provided to kickstart the game, the real challenge lies in deducing the missing ones using pure logic.
