- What Defines a True Sudoku Puzzle?For a puzzle to be a true Sudoku puzzle, it can have one (and only one) solution. There can be no ambiguity in Sudoku. Each number has a single location it must reside in. Otherwise, the player is forced to guess which location to choose thus changing the puzzle into a game of chance.
Each row, column, and nonet can contain each number (typically 1 to 9) exactly once. 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 and to abandon the techniques we will layout below. Don't do it! In order to solve Sudoku puzzles reliably, you must be disciplined, focused, and patient.
It is important to understand that all Sudoku puzzles require an iterative approach. Except for in the case of the most simple puzzles, players will have to visit each nonet more than one time. Fortunately, each successive application of the solution techniques yields more completed cells.
