### Sudoku: A Journey Through History
#### Ancient Roots
The origins of Sudoku can be traced back to the ancient world, though its modern form was not developed until the 20th century. The concept of Sudoku-like puzzles has been found in various cultures and eras. One notable example is the Lo Shu Square, a 3×3 grid that dates back to ancient China around 500 BC. The Lo Shu Square, also known as the “River Lo Symbol,” is based on a magical turtle that appeared in the Yellow River and contained the sequence of numbers 1 to 9, with each row, column, and diagonal summing to 15.
#### Evolution in Japan
In the 19th century, Sudoku began to evolve in Japan. The concept was introduced by Kiyofusa Takahashi in a puzzle magazine under the name “Number Place.” The game became popular in Japan and was known as “Sudoku,” derived from the Japanese words “suu” (number) and “doku” (single).
#### Spread Across the Globe
