Sudoku-- 2.0

Sudoku is a numerical logic reasoning game with origins dating back to the 18th century in Switzerland. It was later introduced to Japan in 1984 by a Japanese scholar and published by Nikoli Company in a gaming magazine under the name Sudoku. Offering various difficulty levels, players can progress from easy to mastering this logic-based game that challenges the mind through deductive reasoning. Using paper and pen, players must deduce the numbers for empty squares on a 9x9 grid based on existing numbers while ensuring that each row, column, and 3x3 section contains digits 1-9 without duplication.

How to play:
The Sudoku grid consists of nine 3x3 sections, each further divided into nine smaller squares. By placing initial set numbers and adhering to problem-solving rules throughout the 81 squares, players must logically fill in missing numbers from 1-9. The goal is to ensure that each number appears only once in every row, column, and section.
