When I saw that Shenzhen Solitaire - the solitaire minigame spun off from Shenzhen I/O - was out for MS-DOS on floppy disks I'll admit I nearly consigned it to the novelty promo pile along with emails about cassette mix tapes or my friend whose response to new music is always "Yes, but can I listen to it on my Discman?". HOWEVER! It gets more interesting because developers Zachtronics have written up the project as a blog post. I didn't follow all the technicalities, but it was super interesting to know more about the choices the pair made, and the quirks of the systems involved under the hood. I find optimisation techniques fascinating so dirty rectangles discussion was a lovely accompaniment to my cup of tea!
The DOS release is available through a Kickstarter running until September 11th.
