Sudoku Dragon gives a wide range of types of hints and suggestions on how to solve Sudoku puzzles. Hints range from checking the state of play so far, to revealing the solution. Features will help both newcomers and experts. An expert will often want to tackle more difficult puzzles and use the facility to mark tentative possibilities on Sudoku squares. You can use square coloring to highlight particular squares. A newcomer may need more help to work out the possibilities for each square. You can use the automatic allocation feature to solve the simpler squares for you, leaving you only the tricky ones to work on. This is particularly useful to mop up those last few easy squares.

There is a full range of ten different puzzle sizes from the introductory 4x4 grid through the regular 9x9 and onto the really challenging 16x16 and 20x20 sized puzzles. The program provides standard, diagonal (or X_Sudoku), Word Sudoku, Samurai Sudoku and Squiggle (or Jigsaw) Sudoku types of puzzle. It has full support for our unique, new types of puzzle : the Sudoku Stripe. If you make a false assumption the solver's undo of square allocations let's you easily back track - you don't need to remember the order you allocated squares. It has support for five different difficulty levels from gentle through to very challenging - for all the ten sizes of puzzle.

You can highlight numbers that have only a few squares remaining to be filled in on the possibility toolbar. You can add your own notes and select your own possibilities and impossibilities for each Sudoku square. Shows all possible locations for numbers in the grid using the possibility toolbar with text explanations of why a number is permitted or why it is not.

Advanced features are provided for the Sudoku expert. Experts will not need to use the possibility display, they may want to work out the possibilities for themselves without help. You can mark individual Sudoku square possibilities and impossibilities by just using the CTRL and SHIFT with a number key. You can add notes to any Sudoku square and these can be printed out with the puzzle. A hint option is provided that allows an expert player to check that all the squares so far allocated are correct - without seeing the whole solution. Another hint option lets you check that all the possibilities that you have marked are genuine possibilities.

The program keeps track of each square allocation that you make so you can quickly and easily go back to try alternative possibilities without needing to remember in which order you set the squares.

To keep Sudoku experts on their toes we provide the very challenging 16x16 and 20x20 grids. Each square has at least 16 possible allocations and this makes it a real test of skill to work through all the possibilities.Puzzle generation has six difficulty levels for each of the ten puzzle sizes.

Flexibility is the key. If you want to change the size, look and feel of the Sudoku puzzle grid this can be done simply and easily. You can choose your own colors and fonts, as well as sound effects. The program will remember these settings each time you play.

Our online forums let you share your successes and queries with other devoted Sudoku players. You can share your special strategies for solving puzzles, swap particular puzzles or just debate the finer points of Sudoku.
