**Large Sudoku Grids: A Comprehensive Guide**
Sudoku, a popular puzzle game, has been captivating minds around the world for years. While traditional Sudoku grids consist of 9×9 cells, large Sudoku grids offer a more challenging and expansive experience. In this guide, we’ll explore the intricacies of large Sudoku grids, their benefits, and how to solve them effectively.
### What is a Large Sudoku Grid?
A large Sudoku grid, also known as an extended Sudoku, is a larger version of the classic 9×9 Sudoku puzzle. These grids typically consist of 16×16 or 25×25 cells, providing a greater number of cells and additional complexity. The rules of large Sudoku grids remain the same as the traditional 9×9 version: each row, column, and 4×4 subgrid must contain all numbers from 1 to the grid’s total number of cells, without repetition.
