RunServer has introduced Classic Solitaire for Mac OS X. It’s a copy of the original Klondike Solitaire card game.

Classic Solitaire feels like the old game, but sports high resolution cards redraw for Retina displays. The game requires Mac OS X 10.7 or later and costs US$0.99.

It’s available on the Mac App Store in the Games category. Go to http://runserver.net/apps/ for more info.
