PySol, which PySolFC is based on, was only for Linux and discontinued in 2004. Unfortunately I cant find Microsoft Solitaire Collection in the Store so we still have to deploy a PowerShell script to get rid of this app. Its features include modern look and feel (uses Ttk widget set), multiple card sets and tableau backgrounds, sound, unlimited undo, player statistics, a hint system, demo games, a solitaire wizard, support for user-written plug-ins, an integrated HTML help browser, and lots of documentation. Some games use the 52 card International Pattern deck, games for the 78 card Tarock deck, eight and ten suits Ganjifa games, Hanafuda games, Matrix games, Mahjongg games, and games for an original hexadecimal-based deck.
PySolFC (PySol Fan Club edition) is an extended version of PySol (a solitaire card games collection) featuring over 1,000 card games.
