SadMan Software Sudoku is priced at $11.95 for a personal single-user license. Buying a license means that SadMan Software Sudoku will continue to operate once the evaluation period has expired, and also entitles you to any upgrades at no additional cost.

You can purchase any of our products through SWREG, a software reseller. Ordering through SWREG is both secure and easy. They can accept your credit card, debit card, international money order, check/cheque or PayPal. The fastest and most convenient method to order our products is using their secure on-line ordering process, although you can also phone or fax your credit card details if you prefer.

Your registration key will be delivered via email.

To enter your registration details, run Sudoku, click the Help -> Enter Registration Key menu option, and enter your name and key exactly as shown on your receipt. Once you've successfully entered your details the Enter Registration Key menu option is no longer visible, and the Help -> About box will show your details. Keep your registration details in a safe place, as you will need to re-enter them if you ever want to move the application to another computer.

Please note that a personal license does not allow you to distribute puzzles created by this program. If you require distribution rights, we can supply a commercial license along with a purpose-built generation program. Alternatively, we can also supply puzzles. Please contact SadMan Software if you require either of these options.
