Sudoku Help - Buying Sudoku Dragon

Here'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 context.

We now offer an alternative product only available for download from Microsoft Store. This shares many features but not all of them. For documentation of the SudokuDragon for Store version see its separate help section.

We need your support to keep on improving the program and managing the web site. The program comes with a long free trial period, after that we ask you to pay for a license to continue to use the product.

We have a simple and secure online purchase process. We use Paypal to securely take your credit / debit card details over the Internet so you can be sure that the process is secure and trouble free. We have been taking online payments for over 25 years. You do not need to download a new version from our web site, the purchase transaction upgrades your license type from 'trial' to 'purchased'.

To start the online purchase process you can use the License menu option from the Help menu. The screen gives details of the license and has a Purchase button to kick off the secure online purchase process in a new web browser window. Please contact us if you have any query or problem with the purchasing procedure.
