In the vein of my first game, Zen Klondike, comes Zen Freecell!
It’s ugly, but free of ads and options. Just bare-bones Freecell like it was meant to be. 
One thing that was fun experimenting with was key pairs in iCloud. This game saves your current win streak and best win streak in the cloud, and uses the latter across your devices. Small time for a lot of you, but as a newbie to making games, every time I try something new and (eventually) get it to work, it feels so good. Especially considering all the ideas in the dumpster fire at the side of the road. Ha ha.
