Sudoku

Sudoku is a logic-based number puzzle game.

Game Objective

Using a few pre-provided numbers as clues, logically deduce and fill in the empty cells so that a 9x9 grid satisfies the following:

1. Each row contains the numbers 1 through 9, with no repeats.
2. Each column contains the numbers 1 through 9, with no repeats.
3. Each 3x3 subgrid (or "box") contains the numbers 1 through 9, with no repeats.
