## Sudoku Help - Puzzle TypesHere's a page from the extensive help system for Sudoku Dragon. It is available as a help screen when running the program. To get the full picture Download our Sudoku Dragon and see the screen in its proper context. Sudoku dragon supports not just the familiar 9x9 puzzle but many variations on this theme. So if you get bored with the standard game try one of the different Sudoku types for a new challenge. ## StandardThe puzzle can be any size from just 2x2 through regular 9x9 to the monster 20x20 grid size. All rows; columns and regions must have all the numbers once only. Variations of region size examples of 2 by 3; 2 by 7 and 4 by 5 grids
## StripeLike the standard puzzle the Striped version can be of any size but a Sudoku Dragon special rule is added as well. Hidden in one row; column or region are the numbers in ascending or descending sequence. This is called the Sudoku stripe. This example Striped Sudoku shows the original puzzle and then the solution with the stripe in column ## DiagonalRather similar is the next Sudoku variation we provide. In this case the diagonals of the grid are also 'groups' and must contain all the numbers once only like the rows; columns and regions. This example Diagonal Sudoku (also called Sudoku-X) shows the original puzzle and then the solution with the diagonals highlighted to show that all numbers 1-9 are present in both diagonals. ## WordIf you get bored with numbers then you can use letters instead, there is no reason why numbers need to be used in a Sudoku puzzle. As an extra twist the letters can form a word. So by solving the puzzle the hidden word (in a row or column) is revealed. If you guess the word from the letters available this can help you solve the puzzle. The Word Sudoku is only available with the 9x9 puzzle size. This example Word Sudoku shows the original puzzle and then the solution. The hidden word 'Outbreaks' is in column ## JigsawSudoku Dragon offers 'Jigsaw' or 'Squiggle' Sudoku. In this case the regions that in the standard Sudoku puzzle are rectangular are allowed to be any interlinked shape - as long as they have the same number of squares. Solving this type of Sudoku requires a few more twists as some of the familiar rules will no longer work. Our Jigsaw puzzles can be of any size. This example Jigsaw Sudoku shows the original puzzle and then the solution. The regions all are in the form of irregular jigsaw pieces but they all still have nine squares in each of them. ## SamuraiA final variation offered by Sudoku Dragon is 'Samurai' Sudoku. The grid contains more than one standard puzzle in an overlapping fashion. The puzzles are linked by the shared squares. - Getting a Sudoku Puzzle
