How to Play Sudoku
The rules of Sudoku are beautifully simple, yet the puzzle can be highly complex. The game consists of a 9x9 grid, divided into nine 3x3 sub-grids. The goal is to fill the entire grid with numbers from 1 to 9 so that:
- Every row contains each number from 1 to 9 exactly once.
- Every column contains each number from 1 to 9 exactly once.
- Every 3x3 sub-grid contains each number from 1 to 9 exactly once.
Tips for Beginners
If you're stuck, try scanning the board for a specific number. For instance, look at where the number "1" is placed across the board. By cross-referencing rows and columns that already contain a "1", you can often logically deduce the only possible remaining square for a "1" in a specific 3x3 box. Remember, Sudoku requires zero math skills—it is entirely a game of logic and deduction!
