Latest Release

Pretty Good Solitaire Mac Edition

Pretty Good Solitaire Mac Edition 3.40 (macOS)

Pretty Good Solitaire is the most comprehensive collection of Solitaire games for the Mac, with 700 different games, plus 80 bonus variants.  It is published by Goodsol Development, who originally released it in 2007.

This title was designed and developed entirely in-house, originally written using C++ and the Carbon framework, and later ported to Objective-C++ and the Cocoa framework.  The core Solitaire functionality uses a custom, cross-platform engine, the Goodsol Solitaire Engine, that is shared (as identical source code) with Windows and iOS products; this engine was also designed and development in its entirety by SophSoft.
