About Sudoku

Sudoku is a popular puzzle game that requires logic and problem-solving skills. The objective of the game is to fill a 9×9 grid with numbers from 1 to 9 in such a way that each row, column, and 3×3 sub-grid contains all the numbers from 1 to 9 without any repetition. The game was invented in Switzerland in the late 1970s, and it gained worldwide popularity in the early 2000s.

To play Sudoku, you start with a partially filled grid, where some of the cells already have numbers in them. Your task is to fill the remaining empty cells with numbers such that each row, column, and 3×3 sub-grid contains all the numbers from 1 to 9 without repetition. The puzzle is solved when all the cells are filled correctly.

The game is played using logic and deduction. You need to use the numbers that are already present in the grid to deduce the possible numbers that can be placed in the empty cells. You can eliminate the numbers that cannot be placed in a particular cell based on the numbers that are already present in its row, column, and 3×3 sub-grid. This process of elimination helps to narrow down the possibilities and solve the puzzle.

Sudoku puzzles can vary in difficulty, ranging from easy to extremely challenging. The difficulty level depends on the number of cells that are filled in at the beginning of the game. The more cells that are already filled, the easier the puzzle is to solve, and vice versa.
