Sudoku Guidelines

The Guidelines of Sudoku

The classic Sudoku game involves a grid of 81 squares. The grid is divided into nine blocks, each containing nine squares.

The rules of the game are simple: each of the nine blocks has to contain all the numbers 1-9 within its squares. Each number can only appear once in a row, column or box.

The difficulty lies in that each vertical nine-square column, or horizontal nine-square line across, within the larger square, must also contain the numbers 1-9, without repetition or omission.

Every puzzle has just one correct solution.

While solving Sudoku puzzles can be significant challenge, the rules for traditional solution finding are quite straight forward:

1. Each row, column, and nonet (A group of nine individuals) can contain each number (typically 1 to 9) exactly once.
2. The sum of all numbers in any nonet, row, or column must match the small number printed in its corner. For traditional Sudoku puzzles featuring the numbers 1 to 9, this sum is equal to 45.

This is an important point to review as it isn’t uncommon for inexperienced players to get frustrated. In order to solve Sudoku puzzles reliably, you must be disciplined, focused, and patient.
