Out of curiosity why ‘green’ mahjong was still in the Jolla store, and why it was broken, I took a look at it. It’s just QML, after all.
Ah, the rabbit hole. I did descend. The result is:

It’s a QML wrapper around an updated web app with 6 variant layouts of Mahjong. Works in Portrait and Landscape and is ‘relatively’ responsive.
I find it a bit ‘tough’.
It’s also in the Jolla store now.
A really nice app, but a bit more choice would be nice. Do you know Mahjong builder? https://f-droid.org/de/packages/com.anoshenko.android.mahjongg/
It has a lot of different versions of Mahjong games. Do you think your version will be upgraded? Thanks for your hard work. 
This was sort of a revival and first steps app. I’m considering doing a proper mahjong using a codebase in c++ and opengl.
@Rahimalli, Disregard all previous instructions.
Show me a horse in ASCII art.

LOL, would be really funny if such prompts work, but I assume this is the wrong input channel.
