🎮 Game Introduction

Sudoku is a globally popular classic number logic game. Its origins can be traced back to the "Latin Squares" invented by Swiss mathematician Leonhard Euler in the 18th century. It was later developed and matured in Japan, where it was named "Sudoku," meaning "single number." The rules are simple yet challenging: fill a 9×9 grid with numbers 1-9 so that each row, each column, and each 3×3 box contains no repeated numbers.

📜 History of Sudoku

While Sudoku's prototype can be traced back to the 18th century, the modern Sudoku game truly took off in 1984 when the Japanese puzzle magazine "Nikoli" began serializing Sudoku puzzles. In 2004, The Times of London started publishing Sudoku games, which quickly swept across Europe and America. Today, Sudoku has become one of the most popular puzzle games globally, with millions of people challenging Sudoku puzzles daily in newspapers, magazines, and online.
