All of our Windows games, including Pretty Good Solitaire, work on the new Windows 10.
If you are installing on a new Windows 10 machine, you can just install using the downloaded install file just as on previous versions of Windows.
If you are upgrading to Windows 10, you may need to reinstall the game, although not always. Some people are able to just run the game after upgrading while others need to reinstall. Unless you erase your files in the process of upgrading, your statistics should also just be there after the upgrade.
You can download Pretty Good Solitaire from https://www.goodsol.com/download.html . Or, if you have a previous version installed, you can run the game, go to the Internet menu, and select "Download Latest Version". Be sure to exit the game before you install.
Version 15.20 is a free upgrade for users who originally ordered version 13 (ordered since April 12, 2011) or have paid for an upgrade since that time. It is not a free upgrade for users who originally ordered version 12 or below. Users of older versions can upgrade for $11.95 at https://www.goodsol.com/upgrade.html .
The quick way to determine whether you need to upgrade to use version 15.20 is to look at your registration code. If your registration code starts with "43", "42", "2a", "2r", or "2g", the upgrade is free and your registration code will work in version 15.20. If your code worked in version 14 or 15, it will work in version 15.20.
If you have lost your code and need to type it in again, you can request that your registration code be sent to you again from https://www.goodsol.com/regusers.html . Note that you should only need to type in a code again when installing on a new machine or after a Windows upgrade or reinstall. Entering your code may or may not also be necessary if you upgrade to Windows 10, depending on how the upgrade is done and what version of Windows you are upgrading from.
Pretty Good Solitaire is US$24.95 for immediate electronic delivery. If you want an additional CD, there is an option to add $9.95 shipping.
