What Is Sudoku? A Game for Relaxation and Self-Improvement

Sudoku is a classic free logic game—a fun, math-based number puzzle of Japanese origin, developed by expert creators. The goal is to fill an 81-square grid with numbers from 1 to 9. The name "Sudoku" combines the Japanese words "Su" (number) and "doku" (unique). Common misspellings include suduku, sodoku, soduko, soduku, and sedoku. Though created in the 1980s, Sudoku surged in global popularity after appearing in newspapers in 2005. Today, it's a staple in publications worldwide. Solving a puzzle typically takes 10 to 30 minutes, depending on difficulty and player skill.
