If you want a brand new puzzle to solve you can just generate a new one simply and easily. Alternatively you can download a new puzzle from our web site or start off with a completely blank grid. It generates a new puzzle totally randomly and as there are billions to choose from, you aren't going to get the same one next time.

We support a large range of grid sizes, by far the most often used is the standard 9 x 9 grid. Smaller grids (4; 6; 8) are however useful for learning the basics of Sudoku. Larger grid sizes are available too, the 16 x 16 and 20 x 20 are super-sized ones that we offer as a challenge for the dedicated puzzle solver.

Choosing the level of difficulty is more tricky as the art and science of Sudoku puzzle solving is a very personal thing. What one person finds easy another may find daunting. We have used a special algorithm to carefully check whether a new puzzle is hard or easy to solve but the intervening 'moderate' levels of difficulty may not generate the level of challenge you expect. It is worth experimenting with the different levels of difficulty until you find one that meets your requirements but the random nature of the generation will ensure that no two generated Sudoku games are ever quite the same !

You can select to display the symbols in the standard sudoku grid with the normal 1' through '9' numbers. If you choose the 16 grid size the program will use the 'hexadecimal numbers' '0' to '9' and 'A' to 'F'. You can also choose to use letters rather than numbers for the grid. This uses 'A' to 'I' for the 9x9 grid and 'A' through 'P' for the 16x16 grid.

It is normal for Sudoku puzzles to have a symmetric pattern of squares initially revealed. Different people take different views on this. A 'random' pattern can offer more challenges to solve it but may be less aesthetically pleasing to look at. Choose which option you like by clicking on the checkbox.

Unique to Sudoku Dragon is the inclusion of a Stripe somewhere within the puzzle. This ensures that the puzzle will have one group with all the numbers (or letters) in order. So one row, column or region will be easier to solve. The order can be 1;2;3;4;5;6;7;8;9 or reversed 9;8;7;6;5;4;3;2;1 and it can be located anywhere in the grid. This makes the Sudoku puzzle a little more fun to solve as finding the stripe can be a useful new way of solving the puzzle. In a hard Sudoku puzzle with so few revealed square it can be a struggle to discover where the stripe is located.

To create the new puzzle press Generate, to create a new blank one with no squares filled in press Blank.
