The generation of new puzzles is a key feature of Sudoku Dragon. You can also download new puzzles from our web site including all the hundreds of free daily puzzles.

When you generate a puzzle you have the option of choosing the level of difficulty from gentle to very challenging. The hard puzzles vary enormously in difficulty as different players use a range of strategies for solving the puzzles. The same puzzle will be easy for some people and impossibly tricky for others.

You can select from a wide range of grid sizes. The 9x9 is the most common size. The smallest 4x4 size is ideal for getting to know the basics while 20x20 puzzles offer a new level of challenge that can be truly daunting. You can choose a size that matches your level of skill.

We offer a range of different forms of the Sudoku puzzle:

Normally 9x9 puzzles use the numbers 0 to 9, but for larger grid sizes there are not enough numbers and so letters are used instead. If you prefer you can use letters for any puzzle size - even 4x4.

The more advanced puzzle player might like to experiment with puzzles that are asymmetric. These do not have the attractive symmetric pattern but a random initial pattern. These puzzles can be much more difficult to solve. The repeated pattern can use rotational symmetry or mirror symmetry.
