The objective is to fill a 9×9 grid with digits in such a way that each column, each row, and each of the nine 3×3 grids that make up the larger 9×9 grid contains all of the digits from 1 to 9. Each Sudoku puzzle begins with some cells filled in. The player uses these seed numbers as a launching point toward finding the unique solution. It is important to stress the fact that no number from 1 to 9 can be repeated in any row or column (although, they can be repeated along the diagonals). Each puzzle has a unique solution which can be found without guessing. SUDOKU PUZZLES 100 x LARGE PRINT Great for the Beginner or Novice Sudoku Player as a Christmas Gift.

Available in PDF, EPUB and Kindle. Book excerpt: This popular, even more challenging variant of sudoku is for true puzzle warriors! Each one consists of FIVE sudoku grids arranged in an X-shaped array, with overlapping corners. No grid can be solved on its own; to complete the entire puzzle, players have to work on several grids at once, making their way to overlapping areas and constantly searching for new clues. While regular sudoku-solving techniques provide the starting point, the game's more complicated than that. Because the overlapping areas belong to two different grids, they must comply with the rules of both simultaneously. That changes the puzzle's underlying logic...and makes these sudokus more fun for the serious fan. An introduction, with a sample puzzle, shows all the strategies.

The objective is to fill a 9×9 grid with digits in such a way that each column, each row, and each of the nine 3×3 grids that make up the larger 9×9 grid contains all of the digits from 1 to 9. Each Sudoku puzzle begins with some cells filled in. The player uses these seed numbers as a launching point toward finding the unique solution. It is important to stress the fact that no number from 1 to 9 can be repeated in any row or column (although, the can be repeated along the diagonals).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. Sudoku Puzzle Variants There are many variations on Sudoku including Mini Sudoku, Cross Sums Sudoku, Killer Sudoku, and Wordoku. We will not cover such variations here. The Rules of Sudoku While solving Sudoku puzzles can be significant challenge, the rules for traditional solution finding are quite straight forward: 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 lay out below. Don't do it! In order to solve Sudoku puzzles reliably, you must be disciplined, focused, and patient. How to Solve Sudoku Puzzles There are two main techniques one can use to solve a Sudoku puzzle; Crosshatching and Penciling In. These two techniques are simple, straightforward, reliable, and sufficient in solving most standard Sudoku puzzles. 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. Sudoku, sudoku puzzles, sudoku puzzles for adults.
