Sudoku Tool License

The Sudoku Tool is licensed and requires activation via the web. A license code is used to initiate the activation process for your valid copy of the tool.
An inexpensive subscription is purchased to obtain an authentic license code.

Two options are available:

  • one year subscription – will require renewal and will need to be re-activated yearly.
  • perpetual subscription – will need to be activated only once.

After the subscription is purchased, an email will be sent to you with your authentic license code. Enter the license code in the license dialog of the Sudoku Tool to activate the license. The license code is a very long string of characters. It is best to “copy and paste” using the clipboard of your PC.

Download the Sudoku Tool. Start the tool on your PC. Copy the code from the email (be sure to get it all) to the clipboard. Paste into the Sudoku Tool license dialog, while the PC is connected to the Internet. A valid code will active the PC to use the tool.
