We know that Ivory has been getting a little long in the tooth. When we first created the iOS version, there were no retina screens, and iPads didn’t even exist yet. We’re currently doing a complete re-write on Ivory—updating all the graphics and building a completely new game engine based on the latest tools from Apple. Unfortunately because we do this in our spare time, we can’t keep maintaining Ivory on all platforms, so we’ll be discontinuing our Windows and MacOS versions so that we can focus all of our development on iOS.
Please bear with us as we try to give you a better mahjongg solitaire game.
