Understanding Sudoku

Sudoku is a popular puzzle game that has been entertaining people of all ages for decades. The game involves filling in numbers on a 9x9 grid, following specific rules to ensure that each row, column, and 3x3 sub-grid contains the numbers 1-9 without repetition.

History of Sudoku

The origins of Sudoku are not well-documented, but it is believed to have originated in Switzerland in the late 19th century. The game was initially called “Latin Squares” and was used as a mathematical tool for testing the intelligence of military recruits. It gained popularity in Japan in the 1970s and was introduced to the world by Nikoli, a Japanese puzzle company.

How to Play Sudoku

Sudoku is a relatively simple game to play:

1. The game starts with some numbers already filled in on the grid.
2. The player’s goal is to fill in the remaining blank cells with numbers from 1-9.
3. Each number can only be used once in each row, column, and 3x3 sub-grid.
4. The game is solved when all blank cells are filled in correctly.
