### Sudoku: The Exciting World of 12×22 and 18×18 Puzzles

#### Introduction to Sudoku

Sudoku is a popular puzzle game that has captured the interest of puzzle enthusiasts worldwide. It’s a game of logic and numbers where the objective is to fill a grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called “boxes”, “blocks”, or “regions”) contain all of the digits from 1 to 9. The challenge lies in the fact that the grid is partially filled, and the player must use logic to determine the missing digits.
